Demonstrate critical and evaluative interpretation and application of theoretical IT/ e-business concepts to a current tourism and hospitality market situation in order to build sustainable competitive advantage. I Introduction Accompanying the technological revolution of the 1990s there are many new opportunities and challenges for the tourism and hospitality industries. Since tourism, global industry information is its life-blood and technology has become fundamental to the ability of the industry to operate effectively and competitively.

It serves as an integral part of the marketing mix, serving as a digital distribution channel as well as an electronic storefront. Consumers in the Internet medium are more than just passive recipients in the marketing process. The Internet is an interactive medium as opposed to traditional marketing which usually allows only one-way communication from marketer to consumer 1.0 PEST ANALYSIS 1.1 POLITICAL / LEGAL Government policies can have a dramatic effect on the Internet and its potential development, by introducing new policies and limitations. The privacy and security issues are also very significant. Therefore, Internet providers have to consider ethical matters and the usage of personal data stored within the networks. For the full commercial potential of electronic commerce and Internet to be exploited by the tourism industry and its consumers, several issues have to be considered, which include an increase of security of transmissions, copyright issues, reduction of user confusion and dissatisfaction, establishment of pricing structures for distribution of information and reservations and enhancement of the standardisation of information and reservation procedures. Credibility and accountability of the information needs to be secured and equal access for smaller and larger partners should be developed.

Ocean Carriers Example

Essays on Ocean Carriers Coursework Finance and Accounting 7th February, The foremost objectives of this analysis are to forecast cash flows and calculate net present value of the company. It also involves calculating internal rate of return, pay back period and discounted pay back period rate. It also involves an analysis on sensitivity analysis on Net Present Value (NPV). Project Cash flows Revenues=Daily hire rate*days hired=20,000*(365*3) =20,000*1,095= 21,900,000 Minus: operating expenses= daily operating expenses*365=$4000*365= (1,460,000) Minus: depreciation= (39,000,000/25) +1/5*500000*(t-1) =1560000+ (100000*0.97) = (1,657,000) operating income (earnings before interest and tax) EBIAT= 18,783,000 Minus: Taxes= 18,783.000*(1-0.35) = 18,783,000*0.65= 12,208,950 Earnings before Interest after Tax = 12,208,950 Plus: Depreciation= 1,460,000 Minus: Capital expenditure (300,000) Minus: Change in net working capital (500,000) Plus: After tax proceeds from sales of equipment = sales price- Tax rate*(sales price-Book value) = 5,000,000-0.35*(5000000-(39000000-1,460,000) = 5000000- 0.35(5000000-37540000) = 5000000+11,389,000 = 16,389,000 = 29,257,950 Cash flow = $ 29,257,950 Ocean carriers as a US firm is a viable project because it will have positive cash flows; therefore, the project should be established because it will add value to the company. Miss Linn should purchase the capsize vessel since it will be profitable to the company. Ocean carriers based in Hong Kong will have high and positive cash flow; therefore, it should be accepted. The tax exemption increases the profits of the company. This makes it even more viable (Pollio, p74). Internal Rate of Return The internal rate of return of this venture is greater than the cost of investment and; therefore the project should be accepted in the case of Ocean carriers being a USA company. This shows that the company will be able to settle its obligations in time. The project will have immediate benefits and return to capital. In the case of being a Hong Kong company, the project should not be accepted because the rate of return is less than the cost of capital of the company. This means the project will take a long time before it benefits the company (Pollio, p79). Payback period and discounted rates The project will take long in the US case before it pays back its obligation. This is as a result of taxation and other challenges that affect the company. The discounted pay back period rates of the company are high meaning that they can not reinvest their profits back in the business as it will affect the company’s operation; therefore, the company will destabilizes. The company will take long to break even which is not a promising analysis to new project. In case of Hong Kong, the pay back period is short. This means that the company will take a short time to pay its debts. This will add on to the high rate of return to capital. This analysis means that the project is viable and should be accepted because will create a positive reputation of the company. The discounted pay back period of the company is positive meaning that it will take a diminutive time for the project to break even which makes the project most viable and; therefore; acceptable (Pollio, p83). Sensitivity analysis There might be errors in the process of analyzing the project. This might make the project viable when it is not. It is therefore, advisable to consider the risk factor in the analysis which eliminates errors. The sensitivity analysis would not have changed the decision to accept the project (Pollio, p85). In conclusion, the project in both cases is viable and should be accepted since it will be profitable to the company. The case of Hong Kong will break even at an early stage; therefore, it is most viable Works Cited Pollio, Gerald. International project Analysis and Financing. Michigan: University of Michigan, 1999.

Two Hacking Incidents JP Morgan (Bank) and Sony Pictures

Questions: 1. Sony Pictures hacked, confidential emails and films leaked? 2. JP Morgan hack affects most US citizens? Answers: Introduction This report is on two stories; the first one is about Sony pictures been hacked and the second one is about JP Morgan, an American bank been hacked. Both the two scenarios were caused due to the malicious activities of the hackers. Sony has faced this kind of situation earlier and yet they did not tighten their network security. The company should enforce good networking systems. The second organization JP Morgan bank; individual details were leaked in public. They should have hired ethical hackers so that the network security could have been better. The Company should incorporate ethical hacking in their system to stop this kind of hacking incidents. These hacking incidents can ruin the reputation of the company and damage their clients evidently (Goldstein, 2010). Actor Network Theory Actor network theory or ANT is concerned with the procedures by which investigative question get to be shut, thoughts acknowledged, instruments and techniques embraced - that is, with how choices are made about what is known. Actor: Any component which curves space around itself, makes other components subordinate upon itself and decipher their will into the dialect it could call its own. Actor Network: A varied network of allied interests 1. Sony Pictures hacked, confidential emails and films leaked Hackers attacked Sony pictures in November 2014. This incident led the company to take decision of turning of their systems. Actants: Hackers; Sony (company) How the actants are acting: It was yet another hit to Sony, which does not have the best notoriety for security, taking after a series of assaults against its PlayStation Network. As insights about the assault rose, it has to be clear that data extends from representative subtle elements - including individual data and messages of big names - to unreleased movies being made open. The assault against Sony Pictures prompted the FBI cautioning US organizations that hackers have utilized vindictive programming to dispatch "damaging" assaults against American associations. At the season of composing, there are no reports about the criminal. North Korea was blamed for this incident at first because the company has made a film about the attempt to assassinate the leader of the country. However, North Korea is denying of any involvement in this incident. Whoever executed the assault, it has been yet another humiliating security episode for Sony. Who is a hacker: In the context of computer security, hacker is somebody who looks for and abuses shortcomings in a PC framework or PC system. A huge number of reasons, for example: benefit, dissent, challenge, enjoyment, or to assess those shortcomings to help with evacuating them may propel programmers (Mcfedries, 2010). The subculture that has advanced around programmers is frequently alluded to as the PC underground and is currently a known group. While different employments of the word programmer exist that are identified with PC security, for example, alluding to somebody with a propelled comprehension of PCs and PC systems, they are infrequently utilized as a part of standard connection. They are liable to the longstanding programmer definition contention about the term's actual significance. In this debate, the term programmer is recovered by PC software engineers who contend that somebody who breaks into PCs, whether computer security expert (white hats) or computer criminal (black hats), is all the more fittingly called a cracker. How cyber crime is controlled: The penetration and attack tests are run in the company can distinguish those powerless focuses in the system that can be effortlessly gotten to from both outer and inward clients (Engebretson, 2010). In the wake of recognizing these centers, you would have the ability to thwart strikes from external sources and right the pitfalls that could transform into the section demonstrate for gatecrashers hack into your framework. The test must be done from both the internal and outside perspectives to recognize all the powerless core interests (Forte, 2010). Acquaint true blue sifting programming activities with perceive all area centers from the web into the internal arrangement of the association. Any attack to the framework needs to start from these core interests (Farsole, Kashikar and Zunzunwala, 2010). Perceiving these segments concentrate however, a straightforward errand is not in the smallest degree. It is perfect to take the help of skilled good softw are engineers who have taken phenomenal framework security get ready to perform this errand adequately. Why the company should use ethical hacking: The Company should incorporate ethical hacking in their system to stop this kind of hacking incidents. These hacking incidents can ruin the reputation of the company and damage their clients evidently. To safeguard their reputation ethical hacking should be introduced in their system. Each and every possible step must be taken to make each one of the customers of the framework aware of the pitfalls of security and the critical security practices to minimize these threats. The organization can coordinate the social-building tests to center the customer care. Until each one of the customers is aware of particular variables related to the framework, affirmation isn't possible in the honest to goodness sentiment the term. 2. JP Morgan hack affects most US citizens JP Morgan is one of the largest banks in America, it was attacked by the hackers in 2014. The information of the customers were traded off by the criminals. Actants: Hackers; JP Morgan (Assaulted organization); Customers How the actants are acting: A virtual assault on JPMorgan Chase traded off the report of seventy six million families and 7 million little companies, a tally that people past evaluations by the bank and puts the disruption among the largest ever. The subtle elements of the break uncovered in a securities recording on 2014 developed during an era when buyer trust in the automated operations of commercial America is shaken. Various different retailers and Home depot have maintained significant information ruptures. The data of 70 million others and 40 million cardholders were traded off at Target a year ago, while an assault at Home Depot in September influenced fifty six million cards. Perhaps if JP Morgan have utilized moral hacking methods that was utilized by the Bank of England, something that could have maybe kept one of the biggest information ruptures ever. The digital assaults against the bank at first happened in August, which prompted the FBI testing Russian government connections to the JP Morgan hack. On the other hand, paying little mind to who completed the assault, the outcomes were to a great degree extensive, with the names, locations, telephone numbers and email locations of 76 million family units and seven million little business records uncovered. What is ethical hacking: Ethical hacker is a networking and computer administration specialist who efficiently actions to enter a PC system for its owners with a goal of discovering vulnerabilities in security that malevolent hackers could possibly abuse (Bodhani, 2012). Ethical hacker utilize the same strategies and methods to test and detour a framework's resistances as their less-principled partners, but instead than exploiting any vulnerabilities discovered, they record them and give significant counsel on the best way to alter them so the association can enhance its general security. Why JP Morgan should have used Ethical hacking: The reason for ethical hacking is to assess the security of a system or framework's base In-text:(Beaver, 2010). It involves discovering and endeavoring to misuse any vulnerability to figure out if unapproved access or different pernicious exercises are conceivable. Vulnerabilities have a tendency to be found in poor or uncalled for framework design, known and obscure equipment or programming defects, and operational shortcomings in procedure or specialized countermeasures. One of the first cases of moral hacking happened in the 1970s, when the United States government utilized gatherings of specialists called "red groups" to hack its own PC frameworks (Palmer, 2001). It has turn into a sizable sub-industry inside of the data security showcase and has extended to likewise cover the physical and human components of an association's resistances. An effective test does not fundamentally mean a system or framework is 100 percent safe, yet i t ought to have the capacity to withstand computerized assaults and untalented programmers. Any association that has a system joined with the Internet or gives an online administration ought to consider subjecting it to an infiltration test. Different guidelines, for example, the Payment Card Industry Data Security Standard oblige organizations to direct entrance testing from both an inside and outside point of view on a yearly premise and after any huge change in the framework or applications. Conclusion This report is on the two hacking incidents that took place in JP Morgan (bank) and Sony Pictures. These two incidents were caused due to lack in the security system or the good and advanced knowledge of the cyber criminals. Both these incidents could have been avoided if the networking of these organizations would have been better. They can employ ethical hackers who would find the loopholes in their system and try to fix the problem or report them to the organization. The purpose behind ethical hacking is to survey the security of a framework or structure's base. It includes finding and attempting to abuse any defenselessness to make sense of if unapproved access.

Cause and Effects of Global Warming Essay Example

Cause and Effects of Global Warming Paper We all know that it is bad but because most people don’t know what to do to help their environment. Well its the simple things like recycling and reducing your carbon-foot print. All these things if each person contributes we can make a better world not just for us but for our children and our grandchildren. Cause and Effects of Global Warming Global warming it’s the increase in the average temperature on Earth. Temperature on earth is controlled by the oceans, the average temperature is fifty-five degrees and if it were to increase or decrease in either direction than it would be the point of no return. The increase of temperature is caused by the release of CO (carbon-dioxide), the methane which both act as greenhouse gases, and the melting of the glaciers are a result. The reason for all this is human interference and disregard for Mother Nature and her limits. Cause 1 Carbon-dioxide is a gas that is released from burning fossil fuels for us most commonly known as oil. When it is burned in the engine of cars a process called combustion which has a byproduct of CO Burning up in combustion†). CO is also released from industries, though they filter what they release it is still harmful to the environment.

It’s our fault that global warming is increasing, so it falls on us to help earth cool down. Carbon-dioxide causes an increase in earth’s global temperature by trapping the heat which is received from the sun which in turn increases the temperature this is called the greenhouse effect. However Carbon-dioxide is not the only cause of the increase in the Earth’s global temperature. Methane is a major contributor to Global Warming. Cause 2 Methane is a greenhouse gas that is mainly from animals expelling gas. While the gas expelled contains many other gases like nitrogen, hydrogen, carbon-dioxide, oxygen, and of course methane. Methane is just like any other greenhouse gas except it is mostly concentrated in agriculture. It is the cows, pigs and goats (Kate Melville) that are fed corn and other grains they get very gassy and â€Å"pass gas† and it is now a major cause of global warming. It is because the agriculture is such a big business and since most of America eats meat to meet that demand the farmers have to raise more cattle and in urn the more cattle there is than the more gas there that is being released. Most people wouldn’t think that they are hurting the environment with what they do every day, eating meat however it is not major because animals would do this anyways right. Well yes to a point but since agriculture is so concentrated that it is having a major impact and this could all be stopped if we all limit how much meat we eat. I have talked on and on about these different gases well why do you care it getting a little hotter well the increase in temperature is having other effects indirectly and we have all heard of this n the news at one point or another and I?s the melting of the glaciers. Cause 3 and Effect Though we have talked about greenhouse gases and what is releasing them, and what they have caused, We have not talked about what happens when the temperature does increase what effect is there to the environment. The increase in temperature cause the glaciers to melt and the melting cause the rocks to show under the ice sheet under Antarctica which heat up becau se of the exposure to the sun. This will cause the ice to melt more causing a reaction that repeats it’s self. They call this a positive feedback loop it means hat it is â€Å"an action that causes a reaction and the reaction causes more of the action, which in turn causes more reaction and so forth†. (Rachel Sway. 2010). The rate of this happening is also increasing because of the hole in the ozone. The ozone is a thin layer of gas that contains 03. The hole in the ozone is caused but the release of Cuff’s or Chlorofluorocarbons Annie Allen). Cuff’s have been banned in the United States for twenty years, countries all around the world also agreed to stop the use of Cuff’s called the Kyoto protocol (Up radiation 2010) but they are still in use in developing Mounties like China and India, however this is only in small amounts and illegally. The ozone layers purpose is to block out UP (ultra violet) rays, they block 99% of UP rays. Now because of the hole the amount of XIV rays entering the earth has increased and this can have major impacts on humans and animals (Up radiation,† 201 0) because the UP rays mutate our DNA. This does not mean that we will mutate and grow a third arm or leg however it can cause skin cancer and cataract. While the uses of Cuff’s have been banned it is our duty as citizens of the world to make sure that other countries adhere to the contract that they signed.

Free Essays on The Best Years Of My Life

Looking back now, I can see that people were right when they said that my high school years would be the best years of my life.

Women Heads of States in Latin America Essay Example | Topics and Well Written Essays - 500 words

Women Heads of States in Latin America - Essay Example More so, there were virtually no female heads of state in Latin America as late as the 1980s. Nevertheless, beginning the 1990s to present, the number of women in executive positions and especially as presidents in Latin America has increased drastically. In this essay we look at two women who have made political impact in Latin America, both in the 20th and 21st centuries. We briefly look at Evita Peron, a 20th century woman and the role she played in shaping the future for Latin American women of the 21st century. Secondly, we look more extensively at Michelle Bachelet, her presidency in Chile and how she has continually championed for women rights. Evita Peron was the most influential woman in Latin American history until the late 20th century. Although Evita never officially held a post in the executive, she was a powerful advocate of women rights in the political arena. Until her death in 1952, Evita was actively engaged in designing policies intended to benefit women in Argenti na. In association with other feminists, Evita formed the â€Å"Peronist Feminist Party† that was designed to help women ascend the political ladder and occupy important political posts (Keen & Haynes, pp. 383). In the social sector, Evita founded a charitable organization that gave financial and legal aid to disadvantaged women in Argentina.

Management - Class Reflection Research Paper Example | Topics and Well Written Essays - 1250 words

Management - Class Reflection - Research Paper Example The last and the most important area is the way to write a flawless dissertation in a cohesive way. The Course Content and Outcome This course has provided me in depth knowledge into the various aspects of research process, and also various forms of research. Evidently, the course gives adequate knowledge about the various aspects of research according to American Psychological Association. It also teaches how to do literature review, various aspects of grammar, and also how to develop a good dissertation. The very first thing I learnt is the use of action research. Contrary to my view that research is something different from doing things practically, the course made me learn how it is possible to ‘learn while doing’ through action research. Also, for the first time, I realized that action research is different from other forms of research in the fact that it turns the people involved into active researchers too. Te researchers do things, observe changes, make modificat ions, and try again until a solution is reached. As Greenwood (1999, pp. 85-87) points out, the research takes place in real life situations and the solutions too come out in real life situations; not in just theory as it often happens with other forms of research. Also, I gained the idea how important it is to have the principles of reflexive critique. As Mike (2007) states, the term ‘reflexive critique’ means to reflect on issues and processes and to make explicit the interpretations, biases, assumptions, and concerns upon which judgments are reached. This is important to do because truth is relative to the teller. This helps developing theoretical considerations from practical accounts. In addition are the factors like dialectical critique and collaborative resources. Thus, I learnt the fact that action research is very useful in such real life situations like a workplace to solve real life problems. As Rehm and Cebula (1996, pp. 1-3) point out, another vital point i s the use of the Search Conference tool which can be effectively utilized in various organizations. Two other research areas explained are qualitative research and quantitative research. Sukamolson (n.d) opines that while qualitative research is about counting and measuring things, producing averages and differences in numbers. Qualitative research stems from social science and hence, is more concerned about people’s knowledge, attitudes, behaviors, beliefs, and fears. In addition, the course made me understand how qualitative research is more useful in identifying a large number of hidden attitudes and values that will be missed in qualitative research. For example, while quantitative research will help in identifying a trend, qualitative research will be required to find the reason behind that trend (QSR International, 2011). In addition, the study gave an insight into various forms of data collection in qualitative research. They are focus groups, direct observation, and i n depth interviews. Some other methods used in qualitative research are diary methods, role play, simulations, and case studies. Also the course helped me understand how difficult it is to conduct an extensive qualitative research as it is more labor intensive than other forms of research. Some other problems as connected to qualitative research are lack of generalizability, possibility of research bias influencing the observation, and poor reproducibility of the

Women In Management (Interview, Biography and Case Study) Essay

Women In Management (Interview, Biography and Case Study) - Essay Example I had a previous experience in sales though. I belonged to the Information Technology CBU (Client Business Unit) and I did enjoy my job for sometime. This was until our manager began to press us for rising sales figures.† The organization where Jessica belongs is essentially a research oriented consultant firm. The function of such an organization is to engage a section of the work force in writing reports and hence the organization would publish them in regular intervals. Jessica has appeared in both in the print and visual media with her expansive knowledge in all subjects and not just pertaining to IT or health. She seems to have specialized in all of them. As she puts it in her words: â€Å" This is not the time to criticize the Jack of all trades, rather the time calls for a Master of all trades. Therefore all children needs to be encouraged to master themselves in all the fields as many areas as possible†. Perhaps that is what she wanted to incorporate in her personality. She reveals how, the decision of her career was influenced by the surprises offered by life and the challenges, which she had to overcome. When it comes to her family life, Jessica is equally frank and honest.

Nursing Information Systems Survey

Nursing Information Systems Survey Study of Nursing Information Systems (NIS) in teaching hospital of Zahedan University of Medical Sciences Leila Erfannial Msc1,Yousef Mehdipour PhD 1,Afsaneh Karimi Msc 1,Ayeshe Zarei Bs 1,Nahid Mehrabi Msc 2 ABSTRACT Purpose: Nurses are one of the biggest providers in health industry that effect directly on health service quality and outcomes. Nurses need correct information in correct time to have an effective service for patient and other member of health society. Nursing information system (NIS) is subsystem of hospital information system that can help nurse to have better performances. The main goal of this study is evaluation of nursing information system in teaching hospital of Zahedan according standard criteria. Materials and Methods: This research is based on a descriptive – cross sectional study that has done on 2013.Nursing information system of 4 teaching hospital in Zahedan were evaluated. For data gathering, we use a checklist that its reliability and validity was verified. Results: According our result, NIS of our study has met 42.19% of priority in general scopes, 72.33% for nursing data set, none of them had classification system standards. They had 45% of nursing data register priorities and 61.12% of report requirement was met. Conclusion: According our system weakness in general aspects, data register and data classification, we propose educational package such as workshops, classes and bulletin for nurses in hospitals toward optimal using of NIS. In other hand , provide nurses with enough hardware requirements , management supervision on using system , provide NIS systems by nursing classification standards and contribution of nurses in selection and implementation of this system is suggested. Keywords: nursing information system; hospital information system; nurse INTRODUCTION There is an increasing growth in information production in different sciences and theqnics, so the management of these volumes of information is very difficult. Information technology is a useful tool for management and useful application of this information. Health industry has faced with increasing rate of information generation that are multiple and complicated in nature1. So health information technology can help this high-demanded industry to manage information. Health information systems are some kinds of tools that integrate and communicate patient data and information and also can process the data and make some new information2. Nurses are one of the biggest providers in health industry that effect directly on health service quality and outcomes. Nurses need correct information in correct time to have an effective service for patient and other member of health society3. Nursing information system (NIS) are subsystem of hospital information system that can help nurse to have better performances, more nursing knowledge and make available data and information for nurses to have a role in health policy making and also decision making around health society and patients4. Furthermore, NIS can participate in hospital information process so lead to a better communication between health care team in hospital 5 . Margaretconclude that using NIS in hospital has a positive effect on information quality that provide by nurses6 .Ammenwerth state that NIS lead to better and more complete documentation of patient information and also better quality of information process5 .Toolabi in her study conclude that optimization of hospital information system would lead to a significant progress in nursing care average and better communication between nurses , patient and health care team and consequently patient more truth to health system ,health services and nurses, more patient family satisfaction and at the end , decrease patient claims7. Zahedan, the capital city of a province in southeast of Iran uses hospital information system in teaching hospital. Nursing information system is one this system module that use in these hospitals. So the basic objective of this study is to evaluate Nursing information system according standard indexes in four sections: general specification of systems, nursing data set , nursing nomenclature and classification specification , documentation registration and reporting specification of systems. MATERIALS AND METHODS This research is based on a descriptive – cross sectional study that has done on 2013.nursing information system of 4 teaching hospital in Zahedan were evaluated. For data gathering, we use a checklist that its reliability and validity was verified. Checklist has 5 section at whole: section 1 has some questions about the system, vendor and some general information about NIS module, section 2 was about general specification of nursing information system. The questions has two answers yes or no.this section involve 23 question about patient care process,11 about ward management process, 10 about communication process and 1 question research and education process.in section 3 , we have some questions about nursing data set that involve 5 question about nursing care data specification, 15 about patient data specification and 14 about service providing data specifications. Section 4 has some question about nursing nomenclature and classification data specification with 25 questions and in section 5 nursing data, registration and reporting requirements were evaluated by 6 questions about personnelreport, 14 questions about clinical report and 3 about financial report. The researchers attended in hospitals and by deep interviewing and also direct observation of systems, gather information and register in checklists. Supervisor of hospital, health information technologist and some professional nurse who uses NIS and familiar with the potential of system was interviewed; furthermore, during interview the researchers can observe the NIS and its functions. After gathering information, we use descriptive statistics to analysis our data by using Excel 2010 tables. RESULTS According our study, general specification of our NIS was evaluated in 5 aspects and 4 hospitals.(table 1) At whole, the frequency of patient care process data specification was 44/56%, ward management data specification was 31.81%, communication process data specification 47.5% and education and research data specification was 50% in our society research. Nursing data set was evaluated in 4 aspects in 4 hospitals: nursing care data set , patient data set, service data set (table 2) According our study , nursing care data set specification was 40% , patient data set specification was 71.66% and service data set specification was 84%. None of our NIS , has nursing classification standards specification data. Data registration and reporting specification data was evaluated in 4 aspects.(table 3) DISCUSSION Information technology making a great service for nurses to perform their tasks8. According our result, by using NIS in all hospital, nurses can receive patient demographic data from admission,discharge,and transmission (ADT) system of hospitals and also can register of different request such as laboratory tests, radiology and pharmacy services. And also they can observe laboratory and radiology results. But none of NIS support nursing evidence based and alert variances from normal patterns. According Ammenwerthstudy, after using information systems, nurses report more quickly patient data documentation, better information monitoring and progress in patient information legibility5. Kossman state that electronic health record implementation in hospital lead to decrease inter-department communication and promote critical thinking between nurses9. Making electronic communication between different parts of hospital is one of the most important capabilities of hospital information systems. According our study, by using nursing information system, in all hospital, nurses can schedule the admission of patients in their wards. Nurses in hospitals can access to information in every place of hospital. In hospital Cand D , nurses can transmit all information by NIS when changing their shifts. According Hinsonstudy , using NIS would lead to the time increasethat nurses spend on patient direct care (10.66%) ,verbal communication 19.33% decrease and mean time for reviewing data 8.9% increase10. Standard NIS needs nursing concepts standards and nursing data standards3. Without unified nursing language , internal data integration and external connection of information would disappear when information are shared and also there would be some problem for clinical decision support.in other hand , nursing information are unstructured generally , so if we don’t use a standard unified language , the retrieval of information would be difficult11. Result of our study show that, none of NIS in Zahedan hospital use standard nursing classification. This issue is very similar to Ahmadi research, they suggest standard nursing classification system for standardization of nursing data and concept to facilities retrieval of information that register in nursing information system12. All NIS in our study, register patient demographic data , nursing diagnostic data and data about service provided by nurses can record ECG data.in hospital C and D , patient vital signs and input-output liquid balance data , can enter to the terminal near patient bed. Anderson state that a standard nursing data set should involve nursing diagnostic data , nursing intervention , nursing outcome and intensity of nursing services and declare , by using such standard data set , management of nursing service cost , supporting of resources that allocated to the nurses , nursing knowledge developed and at the end nursing nursing profession would be promoted13. Making different reports is one of basic management capability of nursing information system that can provide valuable information about personnel productivity, budget management and nursing workload management in different shifts14. In hospital A,B and D , NIS making schedule for personnelshifts. All NIS , can make clinical reports such as laboratory and pathology report and reports about admitted or discharged patients. In Ahmadi study, reporting specification data was met 20.4%,63.5% and 85.2% in personnel , clinical and financial reports4. CONCLUSION Nurses have a great role in health care systems so documentation of their services would be very easy by using nursing information system.so if we want to implement an effective NIS , at first , we should implement a powerful HIS as an infrastructure for any hospital ward subsystem. Nurses are the biggest group of NIS users , so nurses computer literature promotion , has an important role in success and acceptance of NIS. So educational workshop and classes for nurses in hospital would be helpful to make better utilization of nursing information system also increasing inter-hospital communication between nurses and health information technologist would have a helpful tool for transmitting professional knowledge between these groups. Using nurse’s knowledge and skills in all phase electronic system development and implementation and courage electronic health systems developer to use this knowledge in their production is an essential item for successfulness of NIS and systems li ke that. Since we don’t have any national nursing standard classification and nomenclature , prepare , provide an standard unified system according national requirements is another important factor for implementation and usage of NIS and at whole , establishment some professional workshop that has different different profession such as nursing , health information technology , policy making and so on , to start and monitored special effort about nursing information system requirement , development and implementation is very important.

Censorship Laws and Practices in China Essay -- Internet Cyberspace Ce

Censorship Laws and Practices in China Introduction China joined the global Internet age in 1994, and has been commercially available since 1995. Since then, Chinese Internet usage has seen explosive growth, doubling every six months, and the number of online users is only second to the US. The Internet age ushered in the information age with a new world of freedom and expression for the Chinese. However, soon after its inception, the Chinese government has reined in the free wheeling Internet users and has imposed new laws and restrictions to access and content on the Internet. It is interesting to note that some of the new Internet regulations contradict International Laws signed by the Chinese government. China signed the International Covenant on Civil and Political Rights in 1998 that states that â€Å"Everyone shall have the right to freedom of expression; this right shall include freedom to seek, receive and impart information and ideas of all kinds, regardless of frontiers, either orally, in writing or in print†¦or through any other media of his choice†. Overview of China’s Internet Censorship Practices Since the internet's inception in China, regulations have been in place in order to protect â€Å"state secrets†. The first such law was the â€Å"Safety and Protection Regulations for Computer Information Systems†1 put into place in 1994. This law opened the door for monitoring of Internet usage for criminal and other activities. In 1997, the â€Å"Computer Information Network and Internet Security, Protection and Management Regulations† strengthened the monitoring by requiring all Internet Service Providers in China to turn over monthly Internet traffic data to government’s Public Security Bureau.

How Groups Can Influence People in Positive and Negative Ways Essay

Groups influence people in positive and negative ways. Looking at research and studies we will see how the roles we play in groups can influence our behaviour. We will see how groups we gravitate to help raise our self-esteem and give us a sense of belonging but at the same time how conflict is created with other groups. Groups we belong to help to give us a sense of identity but we will see how we can lose this as we conform to group behaviour and the impact this can have. Finally, we will look at Kondo’s research and how changing cultures slowly changed her identity and how this affected her on her journey emphasising her positive and negative influences. As we grow we will have many social identities which influence the groups we belong to. These groups can range from friends to family and further out to groups like nationality and ethnicity. Within these groups we have different roles to play which influence our behaviour. A controversial experiment by Zimbardo (1971) (Spoors et al.) shows how a groups of males were separated into two groups of guards and prisoners in a make shift prison. After six days of a two week experiment it was stopped. The guards became abusive while the prisoners showed signs of emotional disturbance. Lots of factors could have influenced the participant’s behaviour but this experiment shows us the effect that roles have on us in a group and how quick we are to adapt to them. We see how an individual can turn abusive and also how individuals can be walked over an abused. Regarding Zimbardo’s experiment we can identify two groups. Psychologists call these our ‘in’ and ‘out’ groups. Evidence suggests our ‘in group’ raises our self-esteem, we gain a sense of belonging, identification and a sense of status. Our ‘in group’ also gives us an opportunity to compare with our ‘out group’ this can create conflict as an us and them divide is formed. Positively we show favour to our ‘in group’ and negatively we discriminate against our ‘out group’. Tajfel et al. (1971) (Spoors et al.) showed this when he assigned teenage boys to a ‘virtual group’ that did not exist. The boys still showed favouritism to their ‘in group’. We see this behaviour in an experiment conducted by Sherif et al. (1961) (Spoors et al.). He set two sets of boys in a summer camp into groups. Separately the groups interacted, group norms were followed, they joked and had secret codes. The groups were set against each other in competition and within their own groups co-operation and loyalty were heightened but hostility, aggression and prejudiced was seen between the groups. Observing Sherif’s study we see positively how group members found a sense of belonging in their own group and how loyalty and co-operation were heightened by competition. Negatively we see their behaviour changing when clashing against their ‘out group’ becoming hostile, aggressive and prejudiced. Prejudism against our ‘out group’ bolsters self-esteem as it allows us to see other groups as inferior. We feel safe and part of our ‘in group’ but through group pressure we may conform to the rest of the group and the sense of identity we gained we could start to lose as we become more influenced by the rest of the group. Asch (1951) (Spoors et al.) looked at this and conducted an experiment on conformity. Participants had to match two lines out of a group of four that were similar in length with a group of other people. Participants conformed with the group who deliberately gave wrong answers. This was repeated and seventy five per cent of participants gave a wrong answer at least once. Asch’s experiment shows the influence of group pressure. Negatively this influence can have disastrous implications. Spoors et al. (2011) use the example of the ‘Heavens Gate’ cult. Thirty nine of their members committed suicide believing their souls would be transported to a spaceship behind Hale Bop comet. Psychological factors need to be recognised but would they have acted this way left to their own devices? Positively Asch’s experiment shows us how we like to feel part of a group and not left out. Society would be chaos if people did not conform to some degree. Just going to the cinema and being quiet we are conforming to the silence so others are not offended. Cultures will have an influence on conformity as Collectivist cultures emphasise groups more than Individualist cultures so all depending where we live in the world cultures influence our behaviour in groups. As our behaviour changes so will our own social identities and this can finally lead us onto research by Dorinne Kondo (1990) (Spoors et al.) Dorinne Kondo was a Japanese American raised in the U.S.A. She moved to Japan to take part in research involving participant-observational study moving in with a Japanese family. Over time she found her American identity diminishing and her new identity flourishing encountering both positive and negative influences on her journey. Negatively she describes being confronted with bewilderment, embarrassment even anger on her linguistical mistakes and when conforming wrongly to Japanese customs also when ‘proper’ behaviour meant she had to behave subserviently. She describes her conflicts surrounding expectations of gender especially her role as a young woman. Positively she describes being left with a warm positive feeling to her live in family when being affirmed for behaving with proper Japanese etiquette. After time she found herself losing her American identity. In her tea ceremony class she explains her awkward, exaggerated western movements had been replaced with Japanese grace. Kondo’s research demonstrates the positive and negative influences we encounter in different cultures and how they can change us as a person as our identities evolve. We have seen how groups can influence people in both positive and negative ways. Zimbardo’s prison experiment shows us how quick we take up roles in a group and the extent to which we act out these roles. Sherif’s summer camp study shows how we look for a sense of belonging and to raise our self-esteem in a group but how we discriminate when conflict is created. These same groups who we look to for affirmation can influence us so greatly we will make the wrong decisions. We have also seen from research how different cultures can influence our positive and negative behaviour in groups and the impact this has on us as our identities evolve.

Eating Habits essays

Eating Habits essays In Hispanic countries their eating habits are a lot different then our eating habits in the American culture. Their days begin with a small breakfast, not important a very quick and simple meal usually consist of maybe a roll with butter and coffee with hot milk. However, the most important meal of the day is lunch time they go all out unlike ours which is supper time. Their main meal is served between 1:00 and 3:00 in the afternoon. Since this is the most important meal of the day it is customary for the parent/s and children to leave work or school to attend this meal. After the meal there is a set time for a rest period. They rest and get back to doing whatever they were doing to begin with. In the early evening they have a light snack, maybe a sandwich or coffee and rolls. This is mostly for the children.

English Essay Example | Topics and Well Written Essays - 500 words - 1

English - Essay Example It could be an advantage to the agency to dismiss her as it will protect the agency from any further leaks from McCarthy. Another reason I can find for firing McCarthy is the fact that her action broke the agreement of secrecy required by any agent of the CIA. (Shrader,) Again, this means that McCarthy cannot be trusted; however this may not be reason enough to dismiss her. A disadvantage of firing McCarthy is that the media will most likely support McCarthy as it is favorable for the media to take the side of someone who is apparently being fired unfairly. Also, the President may not agree as his interests don't always agree with those of the CIA, according to Senator Menendez. (Shrader) In order to avoid opposition from the president and from the media I feel it might be best to place McCarthy under probation and if it is found she is not to be trusted I will have a solid reason to dismiss McCarthy. I failed one polygraph test and now my job is on the line. (Shrader) I'm sure they want to fire me. I need to gather my thoughts together and analyze this situation. I've already confessed the leak and that could work in my favor. I also need to determine what reasons the agency may have for firing me and not firing me and act accordingly.

Socilogy of Organisation Essay Example | Topics and Well Written Essays - 1500 words

Socilogy of Organisation - Essay Example The term 'power' is obtained from the French term 'poeir' which implies 'being able to take action'. Power is characterised by the ability to carry out or proceed efficiently inclusive of the situational context where not to proceed is considered as most effectual. In a democratic framework, power is essentially categorised against itself, in the archetypal tripartite segmentation of power in governmental, executive and legal power, for example. In modern pluralistic democracies the distribution of power has further implication which is particularly not restricted to the dominion of formal politics. Issues of power concern to languages, communication, promotion, technologies, sciences, fashions, designs, management and varieties of other fields. Evidently, it can be concluded that 'power is everywhere' in terms of relational definition of power attributing to omnipresence, multiplication and dynamism, not restricted to the 'centres of power', as prevalent in legislative organizations and political institutions, for instance. Power is an important aspect of organizational analysis. ... r, in organizational analysis the primary emphasis is on 'power over' in which coercion put prominence on asymmetrical framework while commanding over on resources, like possession on the mode of fabrication, and consent, on the other hand, put stresses on authorities as 'gripping power' revealing a control over all the resources for and after production. There are several numbers of classifications explaining the inferences power over another - the phenomenon is defined as 'forms of power' as described by Russell (1938), subcategorised fundamentally in two headings - - Influence over individuals - Psychological types of influence (Russell, 1938). While understanding the function of an organizational structure, the fundamental methodologies employed to understand the implementation of power need to be recognized. The forms of influence, in practice, are broken down into three general subtypes - - The power of Force and coercion - The power of Inducement and group conformity - The power of Propaganda and/or practice On the other hand, the psychological influences can be subdivided into three distinctive forms such as - - Traditional - Revolutionary - Naked These subtypes can be overlapped with the forms of influences in certain given contexts, for instance, naked power can be trimmed down into coercion alone. Coercion is found to be affected by the influence of carceral power, which is essentially characterised by the experience of agents as 'imprisoned' by virtue of the use of power as a force, as described by Marx, or the attainability of the knowledge of its ability (Weber). Resistance may be overcome by the presence of compliance, which is known as subjectification as 'power through' rather than the presence of naked use of power at the form coercion, which is

Conventional Wars, Rules of Engagement, Chain of Command Essay

Conventional Wars, Rules of Engagement, Chain of Command - Essay Example The implementation of the rule of engagement led him to victories as his attacks were effectively launched. The chain of command broke down responsibilities based on the allocation of specific responsibilities at each position. In addition, each official reported to the one above them (Bevin, 2014). It shows the flow of duties through ranks, from the commander in chief of the armed forces to the individual soldiers in the field. The rules of engagement define the conduct of opposing sides in a war situation Napoleon’s military had individual soldiers in the field who executed decisions made by senior persons in authority. They were the junior most officials of his military. They formed the basis of every attack. Their fundamental task was going out to the battlefield and fighting their opponents. They focused on defeating their enemies in the shortest span of time. The process involved employing tactical methodologies and strategies in launching their attacks to force the opponents do things against their own will. This has always been the fundamental goal of any war (Greene, 2007). The attacks would be organized in troops that had adopted a policy that involved ambushing supply columns. The military had battalion commanders who would execute command from division commanders. The battalion commanders were second lowest in command. They directed orders to the soldiers in the field, who are a fundamental group to any military unit. They would mentor and coach their subordinate staff officers and company commanders. They would be involved in giving morale, enthusiasm in their organizations and training. This would eventually boost their performance at war and consequently lead them to victories. The battalion was capable of independent missions and operations of a specific period of time and scope The military had division commanders who would receive orders from the general. They directed their orders to the battalion commanders. They

Action Research Essay Abstract This paper reports the results of an action research (RA) on the effectiveness of teaching stories in a new way â€Å"Teaching Stories without Telling Them†. The purpose of this research was to justify that how interactive ways of teaching stories enables students to perform better in the classroom, how the interactive teaching expands the knowledge of both teachers and learners, and how the teacher, at the same time, is teaching and drawing on and learning from the knowledge and experience of the students. That creates an ideal teaching cycle, a self-reinforcing teaching and never ending learning process. Introduction The teacher can choose particular designs and techniques for teaching a foreign language in a particular context. No quick fix is guaranteed to provide success for all classroom situations. Every learner is unique; every teacher is unique; so is every learner-teacher relationship. The teacher’s key task is, therefore, to understand the properties of these relationships and set the classroom environment accordingly. In other countries such as Nepal, students are taught to view their teachers  as an authority and a knows-everything person in the classroom, and this value-based relationship hinders the learners from freely expressing themselves in the classroom. In this firmly established teacher-centered system, it is often offensive for the students to contradict the teacher’s point of view. This unequal classroom relationship is often seen as a cultural disposition. I believe that this is not a new issue. Many published writings have critically looked at it. However, a teacher can always adopt various strategies to increase students’ participation in the classroom activities. In order to justify this possibility, I used a technique that I have termed as â€Å"teaching stories without telling them†. If the stories are carefully chosen, students feel what they do in the classroom is relevant and meaningful to their lives. Moreover, when asked to respond personally to the texts, students become increasingly confident about expressing their own ideas and emotions. The stories involve emotions as well as intellect, which adds to motivation and contribute to personal development. This is in particular very useful where the classroom is often only source of English. Background I’m a new English Teacher at Kaunlaran High School but I have been teaching English for the last four year. The pre-requisite to join this programme is School Leaving Certificate (SLC). Practically, the students who join this course range from SLC graduates to University graduates. I also work at â€Å"English Speaking and Research Club† that runs classes for those who want to improve their speaking skills. Interestingly, the members coming to this Club include school students to professionals and businesspersons. Certainly, the classes in both settings are multilevel in nature. I would like to refer to Hess’s (2002) definition multilevel class is the class in which students vary considerably in their language and literary skills. In my case, students not only differed in language level, but also in age, motivation, expectations, attitude and interest. The Procedure In both places, I began with a pre-test in order to diagnose the learners  level of English. The candidates were tested all their skills – first day reading and writing and the second day speaking and listening. Later they were divided into three groups named as triple five (those scoring less than 50%), triple seven (those scoring between 50-60 %) and triple six (those scoring 60% above) according to their test results; but they were not informed about it. Action plan teaching process Selecting a story: (I selected stories from books available in the market. I purposely chose books that had an appropriate level of difficulty and length.) Briefing the students about the different nature of class: (I told my students that they would have to read the text and be able to answer the questions I would ask them in the class. I did not read the story. My role as a teacher and facilitator was to ask questions very carefully so that I would be able understand the story and students’ role was to make me understand the story.) Giving students the story to read at home as reading assignment: (I gave each student a copy of the same story to read at home.) Grouping the students according to their language proficiency level and carrying out the class: (I asked simple factual questions to below average group i.e. 555; reflective questions to average group i.e. 777; and interpretive and judgmental questions to above average group i.e. 666. This actually engaged every student in the classroom activity. Moreover, they were very attentive when someone was speaking. This various types of questions actually motivated all level students to participate in the classroom activity.) Carry out discussion: (I was very careful while carrying out the discussion. Sometimes the students gave contradictory answers to the same question I asked. In such situation I played a very careful role – I gave the students equal opportunity to justify their answers. My job was to facilitate them to come to an agreeing point.) Giving home assignment: (I gave different tasks to different group – I asked the below average group to write a summary of the story, I asked the average group to imagine one of the characters in the story and write the story from their own perspective. For example, imagine that you are the Brahmin in the story, write a paragraph how these three thieves cheated you. I asked the above average group to interpret t he story using their own feelings and emotions. For example, do you think you would punish these thieves if you  were a judge? Write a very logical paragraph of your argumentations. The students at the beginning were little puzzled but did not express openly. However, they participated very actively in the classroom activities. My primary aim was to promote learner autonomy, by encouraging them to take charge of their own learning (Nguyen, 2005). This became even more interesting as I purposely did not read the story to create a real information gap. If I had read the story, I would already have known everything and then the questions I asked in the classroom would have been merely mechanical ones. For this reason, I claim that the classroom language was authentic. Classroom activity In the classroom, I asked four different types of questions: factual, reflective, interpretive, and judgmental. It is vital that we understand the nature of the different types of question. I have briefly described what they mean and quoted some sample questions I used in my classroom and their respective answers that students gave. They are as follows. a) Factual questions: the questions are very simple and they can pick up the answer from the text very easily such as: T: what is the title of the story? 555: Brahmin and thieves (they can pick from the text) T: How many characters are there? 555: There are four; one Brahmin and three thieves. b) Reflective questions: the types of questions are related with peoples’ emotions, feelings and associations for which the students have to use their won feelings to characters, event and plot of the story such as: T: What could be another suitable title? 777: Brahmin and the goat (they have to associate with the text.) T: why did they try to fool the Brahmin? 777: because they want the goat. c) Interpretive questions: the types of questions are related with meaning,  purpose and values such as: T: Why do you think the title should be Brahmin and goat? 666: Because the goat also has main role in the story. d) Judgmental question: these sorts of questions allow the students to decide their feelings, emotions and response to the topic and discussion they have had together such as: T: Write a very logical description, why do you want to punish one? 666: I should judge very carefully. We all know that if we miss judge then there is no one to help poor people. In this case, any way the Brahmin is (sis) victim †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. In this way, every learner participated in the class. Though the class was multilevel, the task designed for different levels was really challenging. The classroom rule was that only the group was supposed to answer the question, in case they did not answer then other group would answer. As far as the error correction concerned, I did not correct all the errors they made in the discussion. It does not mean that I ignored all the errors. I corrected only global error not the local error. I agree with Brown’s (2000) definition that the local error is clearly and humorously recognized and recommended that they may not be corrected as long as the message is understood and correction may interrupt a learner in the flow of communication. The global error needs to be corrected in some way since the message may otherwise remain unclear and rather ambiguous. I have corrected the errors watching the situation without disturbing in their attempt to produce the language. The result I found a dramatic change in the classroom atmosphere: all trying to say something, listening to others what they say. In fact, I had never had such satisfaction in my class before even though I used pair work, group work and role-play. In this sense, I agree with Nunan’s (as cited in Hiep 2005) suggestion that the teacher should use such activities that involve oral communication, carrying out meaningful tasks and using language which is meaningful to the learners and as well as the use of materials that promote  communicative language use. Such activities helped the learners to find the ways of helping them to connect what is in the text to what is in their minds. One of the major advantages of this approach is that texts can be selected based on the richness and diversity of the language and on the relevance to the English learners who should find them both meaningful and motivating. I refer Nguyen (2005:5) â€Å"Exposing students to varieties of stories let them experie nce not only the beautiful language but also something beyond, such as sympathy with characters and engagement with emotional situations that relate to their actual lives. As a result, I found the activities vital for progress in language learning process. Such discussion certainly enhances students’ ability to pay attention, remember new grammar and vocabulary, process ideas and response appropriately. Moreover, students get enough chances to express their own ideas and opinions and discuss the opinions and ideas of other students. I agree with Byrd and Cabetas (1991:9) ‘by discussing these differences students learn to use English more clearly and to understand it better.† Moreover, they learn to clarify their own ideas, values, perspectives, and learn from others. A major innovation that I have noticed about this technique is to systematically build students’ ability to present their own ideas, opinions and feelings both accurately and confidently. I have particularly focused on maximizing student-talking time and minimizing teacher-talking time in the classroom setting. This action research proved the idea of Breen and Candlin (as cited in Byrd and Cabetas 1991) that the teacher has two roles: the first role is to facilitate the communicative process and to act as an independent participant within the teaching-learning process; second role is that of researcher and learner.

Intrusion detection system for internet

Intrusion detection system for internet ABSTRACT The visibility to detect the rapid growth of Internet attacks becomes an important issue in network security. Intrusion detection system (IDS) acts as necessary complement to firewall for monitoring packets on the computer network, performing analysis and incident-responses to the suspicious traffic. This report presents the design, implementation and experimentation of Network Intrusion Detection System (NIDS), which aims at providing effective network and anomaly based intrusion detection using ANOVA (Analysis of Variance) statistic. A generic system modelling approach and architecture are design for building the NIDS with useful functionalities. Solving the shortcomings of current statistical methods in anomaly based network intrusion detection system is one of the design objectives in this project as all of them reflect the necessary improvements in the network-based IDS industry. Throughout the system development of NIDS, several aspects for building an affective network-based IDS are emphasized, such as the statistical method implementation, packet analysis and detection capabilities. A step by step anomaly detection using ANOVA (Analysis of Variance) test has been calculated in the report. Chapter 1 Introduction This chapter is introduction to the whole project. This chapter introduce the project, its motivation, main objective and advance objectives. The chapter also give brief methodology of the research. Introduction The Though with the rapid growth of computer networks make life faster and easier, while on the other side it makes life insecure as well. Internet banking, on line buying, selling, on internet, is now part of our daily life, along with that, if we look at growing incidents of cyber attacks, security become a problem of great significance. Firewalls are no longer considered sufficient for reliable security, especially against zero error attacks. The security concern companies are now moving towards an additional layer of protection in the form of Intrusion Detection System. D.Yang, A.Usynin W.Hines (2006) explain intrusion and intrusion detection as: Any action that is not legally allowed for a user to take towards an information system is called intrusion and intrusion detection is a process of detecting and tracing inappropriate, and incorrect, or anomalous activity targeted at computing and networking resources [16]. Idea of intrusion detection was first introduced in 1980 (J.P Anderson) and first intrusion detection model was suggested in 1987 (D.E.Denning). Intrusion Prevention System (IPS) is considered as first line of defence and Intrusion Detection Systems are considered as second line defence [16]. IDS are useful once an intrusion has occurred to contain the resulting damage. Snot is best example of working Intrusion Detection System and Intrusion Prevention Systems (IDS/IPS) developed by Sourcefire. Which combine the benefits of signature, protocol and anomaly based inspection. IDS can be classified in to misuse detection and anomaly detection. Misuse detection or signature based IDS can detect intrusion based on known attack patterns or known system vulnerabilities or known intrusive scenarios where as anomaly intrusion detection or not-use detection systems are useful against zero -day attacks, pseudo zero-day attack. Anomaly based IDS based on assumption that behaviour of intruder is different from normal user. Anomaly detection systems can be divided into static and dynamic, S.Chebrolu, et al A.Abraham J.P.Thomas (2004). Static anomaly detectors assume that the portion of system being monitored will not change and they mostly address the software area of the system [17]. Protocol anomaly detection could be the best example of static anomaly detection [17]. Dynamic anomaly detection systems operate on network traffic data or audit records and that will be the main area of my interest in research. Anomaly IDS has become a popular research area due to strength of tracing zero-day threats, B.Schneier (2002). It examines user profiles and audit records etc, and targets the intruder by identifying the deviation from normal user behaviour and alert from potential unseen attacks [18]. Active attacks have more tendencies to be traced as compared to passive attacks, but in ideal IDS we try to traces both. Anomaly based Intrusion detection system are the next generation IDS and in system defence they are considered as second line of defence. In that research my main concentration will be Denial of service attacks their types and how to trace them. Motivations Though Internet is the well knowing technology of the day but still there are security concerns such as internet security and availability. The big threat to information security and availability is intrusion and denial-of-service attacks. Since the existing internet was developed about 40 year ago, at that time the priorities were different. Then unexpected growth of internet result exhaustion IPV4 address along with that it brings lots of security issues as well. According to the CERT statistical data 44,074 vulnerabilities had been reported till 2008. Intrusion is the main issue in computer networks. There are too many signature based intrusion detection are used within information systems. But these intrusion detection systems can only detect known intrusion. Another approach called anomaly based intrusion detection is the dominant technology now. Many organizations are working on anomaly based intrusion detection systems. Many organizations such as Massachusetts Institute of Technology are providing data set for this purpose. Motivated by the observation that there is lots of work is done using the Massachusetts Institute of Technology (MIT) data sets. Another aspect of the anomaly based intrusion detection system is statistical method. There are too many good multivariate statistical techniques e,g Multivariate Cumulative Sum (MCUSUM) and Multivariate Exponentially Weighted Moving Average (MEWMA) are used for anomaly detection in the wild of manufacturing systems [3]. Theoretically, these multivariate statistical methods can be used to intrusion detection for examining and detecting anomaly of a subject in the wild of information science. Practically it is not possible because of the computationally intensive procedures of these statistical techniques cannot meet the requirements of intrusion detection systems for several reasons. First, intrusion detection systems deal with huge amount of high-dimensional process data because of large number of behaviours and a high frequency of events occurrence [3]. Second, intrusion detection systems demand a minimum delay of processing of each event in computer systems to make sure an early d etection and signals of intrusions. Therefore, a method which study the variation is called ANOVA statistic would be used in this research. But there is no research available that have implemented ANOVA and F statistic on data sets collected by The Cooperative Association for Internet Data Analysis (CAIDA). The data sets provided by CAIDA are unique in their nature as it does not contain any session flow, any traffic between the attacker and the attack victim. It contains only reflections from the attack victim that went back to other real or spoof IP addresses. It creates trouble in estimating the attack. I will take that trouble as challenge. Research Question In this section I will explore the core objective of the research and a road map to achieve those objectives. During that research I will study data sets called backscatter-2008, collected by CAIDA for denial of services attacks. I will use statistical technique ANOVA to detect anomaly activities in computer networks. My research is guided by five questions. What is an intrusion and intrusion detection system? How can we classify intrusion detection system? What are different methodologies proposed for intrusion detection systems? How to analyse the CAIDA Backscatter-2008 data sets and make them ready for future study and analysis. How to figure out the different types of DOS attacks. How to implement ANOVA statistical techniques to detect anomaly in networks traffics Aims and Objectives Dos attacks are too many in numbers and it is not possible to discuss all the dos attacks in one paper. In this paper I will look to detect anomaly in network traffic using number of packets. Main/Core objectives of the research Review literature of recent intrusion detection approaches and techniques. Discuss current intrusion detection system used in computer networks Obtaining a data set from CAIDA organization for analysis and future study. Pre-process the trace collected by CAIDA, make it ready for future analysis. Recognizing the normal and anomaly network traffic in CAIDA dataset called backscatter-2008. Investigate Analyse deviated network traffic using MATLAB for different variants of denial of services attacks. Review of existing statistical techniques for anomaly detection Evaluation of the proposed system model Advance Objectives of the research Extend the system model to detect new security attacks. Investigating and analysing the ANOVA statistical techniques over other statistics for anomaly detection in computer networks. Nature and Methodology The area of research is related with detecting anomaly traffic in computer networks. The revolution in processing and storage capabilities in the computing made it possible to capture, store computer network traffic and then different kind of data patterns are derived from the captured data traffic. These data patterns are analysed to build profile for the network traffic. Deviations from these normal profiles will be considered anomaly in the computer network traffic. This research presents a study of vulnerability in TCP/IP and attacks that can be initiated. Also the purpose of research is to study TCP flags, find distribution for the network traffic and then apply ANOVA statistical techniques to identify potential anomaly traffic on the network.

Chapter 3: Security Vulnerabilities and Threats in Computer Networks This area of report is dedicated to the Network Security in general and issues with computer networks. Then types of Denial of services attacks are described in general. This chapter also include Types of DOS attacks and brief description of each attack. Chapter 4: Data Source Data sets collected and uploaded by CAIDA on their web site are not in a format to be processed straight away. This chapter described in detail how to obtain those data sets. Then all the necessary steps that are carried out on the data sets to convert that trace into format that is understood by MATLAB for final analysis. It also includes the problems faced during the pre-processing of data sets as there not enough material available on internet for pre-processing of datasets and the application used during that phase. Chapter 5: System Model As the research is based on TCP/IP protocol So it is vital to discuss the TCP and the weak points that allow that attacker to take advantage and use them for malicious purpose.

What is the nature of the research and which method will be used in it are in picture. The topic provides overall background information. Furthermore explanation of the report structure and brief description of all the chapters are also included in this chapter. Chapter 2 Research Background Introduction The focus of this chapter is to explain, what is intrusion and intrusion detection system. Why we need Intrusion Detection System. This chapter also discuss types and techniques used for Intrusion Detection Systems. Goals, challenges and problems are the main parts of the Intrusion Detection System are also explained in this chapter. Intrusion Detection System (IDS) A computer intrusion is the number of events that breaches the security of a system. Such number of events must be detected in proactive manner in order to guarantee the confidentiality, integrity and availability of resources of a computer system. An intrusion into an information system is a malicious activity that compromises its security (e.g. integrity, confidentiality, and availability) through a series of events in the information system. For example intrusion may compromise the integrity and confidentiality of an information system by gaining root level access and then modifying and stealing information. Another type of intrusion is denial-of-service intrusion that compromises the availability of an information system by flooding a server with an overwhelming number of service requests to the server over short period of time and thus makes services unavailable to legitimate users. According to D. Yang, A. Usynin W. Hines, they describe intrusion and intrusion detection as: An y action that is not legally allowed for a user to take towards an information system is called intrusion and intrusion detection is a process of detecting and tracing inappropriate, and incorrect, or anomalous activity targeted at computing and networking resources. Why we need Intrusion Detection System To provide guarantee of integrity, confidentiality and availability of the computer system resources, we need a system that supervise events, processes and actions within an information system [1]. The limitations of current traditional methods, misconfigured control access policies and also the misconfigured firewalls policies in computer systems and computer network security systems (Basic motivation to prevent security failures), along with increasing number of exploitable bugs in computer network software, have made it very obvious to design security oriented monitoring systems to supervise system events in context of security violations [1]. These traditional systems do not notify the system administrator about the misuses or anomaly events in the system. So we need a system which provides proactive decision about misuse or anomaly events, so therefore from last two decades the intrusion detection systems importance is growing day by day. Now a days intrusion detection system plays vital role in an organization computers security infrastructure. Types of Intrusion Detection System Intrusion detection system is a technique that supervises computers or networks for unauthorized login, events, activity, or file deletion or modifications [1]. Intrusion detection system can also be designed to monitor network traffic, so it can detect denial of service attacks, such as SYN, RST, ICMP attacks. Typically intrusion detection system can be classified into two types [1]. Host-Based Intrusion Detection System (HIDS) Network-Based Intrusion Detection System (NIDS) Each of the above two types of intrusion detection system has their own different approach to supervise, monitor and secure data, and each has distinct merits and demerits. In short words, host based intrusion detection system analyse activity occurrence on individual computers, while on the other hand network based IDSs examine traffic of the whole computer network. Host-Based Intrusion Detection System Host based intrusion detection gather and analyse audit records from a computer that provide services such as Password services, DHCP services, web services etc [1]. The host based intrusion detection systems (HIDS) are mostly platform dependent because each platform has different audit record from other platforms. It includes an agent on a host which detect intrusion by examining system audit records, for example audit record may be system calls, application logs, file-system modification (access control list data base modification, password file modification) and other system or users events or actions on the system. Intrusion detection system were first developed and implemented as a host based [1]. In host based intrusion detection systems once the audit records is aggregated for a specific computer, it can be sent to a central machine for analysis, or it can be examined for analysis on the local machine as well. These types of intrusion detection systems are highly effective for detecting inside intrusion events. An unauthorized modification, accesses, and retrieval of files can detect effectively by host based intrusion detection system. Issues involve in host based intrusion detection systems is the collection of audit records for thousands of computer may insufficient or ineffective. Windows NT/2000 security events logs, RDMS audit sources, UNIX Syslog, and Enterprises Management systems audit data (such as Tivoli) are the possible implementations of the host based intrusion detection system. Network-Based Intrusion Detection System Network-based intrusion detection system (NIDS) is completely platform independent intrusion detection system which predicts intrusion in network traffic by analysing network traffic such as frames , packets and TCP segments (network address, port number, protocols TCP headers, TCP flags etc) and network bandwidth as well. The NIDS examines and compared the captured packets with already analysed data to recognize their nature for anomaly or malicious activity. NIDS is supervising the whole network, so it should be more distributed than HIDS. NIDS does not examine information that originate from a computer but uses specials techniques like packet sniffing to take out data from TCP/IP or other protocols travelling along the computer network [1]. HIDS and NIDS can also be used as combination. My project focus on network based intrusion detection systems, in this project we analyse TCP flags for detecting intrusions. Techniques Used in Existing IDS In the above section we discussed about the general existing type of the intrusion detection system. Now the question arises that how these intrusion detection system detect the intrusion. There are two major techniques are used for above each intrusion detection system to detect intruder. Signature Detection or Misuse Detection Anomaly Detection Signature Detection or Misuse Detection This technique commonly called signature detection, this technique first derives a pattern for each known intrusive scenarios and then it is stored in a data base [3]. These patterns are called signatures. A signature can be as simple as a three failed login or a pattern that matches a specific portion of network traffic or it may be a sequence of string or bits [1]. Then this technique tests the current behaviour of the subject with store signature data base and signals an intrusion when there is a same pattern match. The main limitation in this technique, that it cannot detect new attacks whose signatures are unknown. Anomaly Detection In this technique the IDS develop a profile of the subjects normal behaviour (norm profile) or baseline of normal usage patterns. Subject of interest may be a host system, user, privileged program, file, computer network etc. Then this technique compare the observed behaviour of the subject with its normal profile and alarm an intrusion when the subjects observe activity departs from its normal profile [3]. For comparison, anomaly detection method use statistical techniques e,g ANOVA K-mean, Standard Deviations, Linear regressions, etc [2]. In my project, I am using ANOVA statistic for anomaly detection. Anomaly detection technique can detect both known and new intrusion in the information system if and only if, there is departure between norm and observed profile [3]. For example, in denial of service attack, intrusion occurs through flooding a server, the ratio of the events to the server is much higher than the events ratio of the norm operation condition [3]. Issues and Challenges in the IDS An intrusion detection system should recognize a substantial percentage of intrusion while maintain the false alarm rate at acceptable level [4]. The major challenge for IDS is the base rate fallacy. The base rate fallacy can be explained in false positive false negative. False positive means when there is no intrusion and the IDS detect intrusion in the event. False negative when there is an intrusion in the events and the IDS does not detect it. Unfortunately, the nature of the probability includes, and the overlapping area between the observed and training data, it is very difficult to keep the standard of the high rate of detections with low rate of false alarms [4]. According study held on the current intrusion detection systems depicted that the existing intrusion detection systems have not solved the problem of base rate fallacy [4]. Summary An intrusion into information system compromises security of the information system. A system, called intrusion detection is used to detect intrusion into information system. The two major types of IDS are HIDS and NIDS. The host based intrusion detection system monitor mostly the events on the host computer, while the NIDS monitor the activity of the computer network system. There are two approaches implemented for intrusion detection in IDS, anomaly and signature. Anomaly use statistical methods for detecting anomaly in the observed behaviour while signature check patterns in it. Base rate fallacy is the major challenge for IDS. Chapter 3 Security Vulnerabilities and threats in Networks Introduction In this chapter we are going to discuss the computer and network security. For computer security, there are some other terminologies like vulnerability, exploitability and threats are discussed as well in the chapter. Then chapter focus on Denial of Service attack, which is the most dominant attack in the wild of computer science. The chapter also concentrate the all aspects of the denial of service attack. Computer Security In the early days of the internet, network attacks have been a difficult problem. As the economy, business, banks and organization and society becomes more dependent on the internet, network attacks put a problem of huge significance. Computer security preclude attacker from getting the objectives through unauthorized use of computers and networks [5]. According to the Robert C. Searcord Security has developmental and operational elements [5]. Developmental security means, developing secure software with secure design and flawless implementation [5]. Operational Security means, securing the implemented system and networks from attacks. In computer security the following terminologies are used most commonly [5]. Security Policy: A set of rules and rehearses that are typically implemented by the network or system administrator to their system or network to protect it from attacks are called security policies. Security Flaw: A software fault that offers a potential security risk is called security flaw. Vulnerability: the term vulnerability is a set of conditions through malicious user implicitly or explicitly violates security policy. Exploit: a set of tools, software, or techniques that get benefit of security vulnerability to breach implicit or explicit security policy [5]. The term information security and network security are often used interchangeably. However, this project focus intrusion in computer networks, so we are going to discuss network security. The term network security is the techniques that are used to protect data from the hacker travelling on computer networks. Network security Issues There are many issued involved in the network security but the following are the most common. Known vulnerabilities are too many and new vulnerabilities are being discovered every day. In denial of service attack when the malicious user, attack on the resources of the remote server, so there is no typical way to distinguish bad and good requests. Vulnerability in TCP/IP protocols. Denial of service Attacks A denial of service attacks or distributed denial of service attack is an attempt to make computer resources exhausts or disable or unavailable to its legitimate users. These resources may be network bandwidth, computing power, computer services, or operating system data structure. When this attack is launched from a single machine, or network node then it is called denial of service attack. But now days in the computer wild the most serious threat is distributed denial of service attack [4]. In distributed denial of service attack, the attacker first gain access to the number of host throughout the internet, then the attacker uses these victims as launch pad simultaneously or in a coordinated fashion to launch the attack upon the targets. There are two basic classes of DoS attacks: logic attacks and resource attacks. Ping-of-Death, exploits current software flaws to degrade or crash the remote server is an example of the logic attacks. While on the other hand in resource attacks, the victims CPU, memory, or network resources are overwhelmed by sending large amount of wrong requests. Because the remote server, does not differentiate the bad and good request, so to defend attack on resources is not possible. Various denials of service attacks have some special characteristics Oleksii ignatenko explain the characteristics of the denial of service attacks as in the figure 1. Your browser may not support display of this image. Figure 1 Denial of service attack characteristics Attack type: a denial of service can be a distributed (when it comes from many sources) or non-distributed (when it comes from only one source). Attack Direction: attack direction may be network or system resources. Attack Scheme: Attack Scheme can be direct from malicious users source or it can be reflections form other victims systems, or it can be hidden. Attack Method: Method means that vulnerability that allows attack. Targeted attack utilizes vulnerability in protocols, software and services, while consumption method consumes all possible resources. Exploitive attacks take advantages of defects in operating system. operating system Methods for Implementing Denial of Service Attacks A denial of service attack can be implemented in many ways; the following are the most common implantation techniques Attempt to flood a network, thereby stopping legitimate network traffic Attempt to interrupt connections between two systems, thereby preclude access to a service Attempt to prevent a specific user from accessing a service The flood method can be deployed in many ways but the following are well known in the wild of networks system. TCP-SYN Flood ICMP Flood RST attack TCP-SYN Flood: In order to achieve the TCP-SYN flood the attacker tries to establish the connection to the server. Normally a client establishes a connection to the server through three way handshake. In three way handshake, The client or any sender sends the TCP packet with the SYN flag set. The server or receiver receives the TCP packet, it sends TCP packet with both SYN and ACK bits are set. The client receives SYN-ACK packet and send ACK packet to the server. The three way handshake can easily be understood in the figure 2: Client Server Your browser may not support display of this image.Your browser may not support display of this image.Your browser may not support display of this image.

Figure 2 Three way Handshake This is called three way handshake of TCP connection establishment. So in SYN flood what the attacker does, he sends SYN packet to the server and the server responds with SYN-ACK packets but the attacker does not sends the ACK packet. If the server does not receive the ACK packet from the client it will resends a SYN-ACK packet again after waiting for 3 seconds. If SYN-ACK still does not arrive, the server will send another SYN-ACK after 6 seconds. This doubling in time continuous for a total of 4 or 6 attempts (the exact number depends upon the implementation of the TCP protocol on the server side) [8]. So in SYN flood the attacker install Zombies on Internet hosts and sends huge amount of SYN request from spoof IP to the server or any host on the internet and utilize all the server or host memory and data structure. In this way the server get busy and is not able to accept request or respond to
