Paleolithic and Neolithic Ages Ap History
Paleolithic and Neolithic Ages The Neolithic Age changed the way people live now a days for many reasons. First of all, in this era agriculture was very important. People could farm instead of hunting and gathering and also they could settle down in one place. People also began to live in small communities. Settling down in one place meant more food and free time. This started trade because there were food surpluses and began the first forms of government. There were many things to be done so they divided work up among everyone in the small community.This was the very beginning of the way we live today. The Paleolithic Age is the Old Stone Age ending in 1200 B. C. E. were stone tools were used for hunting and gathering. People used tools such as clubs and choppers to crack open bones. Tools in this era were mainly made to use for shelter, defense, and keepings of food and clothing. These people believed in an afterlife which was similar to actual life on Earth because they were provi ded with all the tools, weapons and necessities needed to survive which was stated in document 1.In this age scholars believed that their ancestors lived in a world of spirits and shown in document 2 these people were hunters. The Neolithic Age is the New Stone Age between 8000 and 5000 B. C. E. were the adaptation of sedentary agriculture occurred and were domestication of plants and animals occurred. This is the era where people began to develop social groups and create civilizations and stop moving from place to place. Stated in the document 4 people began to depend more on animals and less on plants.They followed herds of animals instead of just one to get more food and eventually create a surplus. The animals that they herded gave them the fertilizer for agriculture. In document 5 it says that there were settled farming communities and they began to create a council to make decisions on what to harvest. Settled people had more personal property. These differences were so import ant because of the technology and ways of life that these people started to create.If the people from the Paleolithic and Neolithic ages didnââ¬â¢t discover the things that they did our world today would be totally different. There are many possibilities on what our life would be like today if these people didnââ¬â¢t start a foundation for us. In conclusion, as you can see the Neolithic age changed how we live greatly. They started the first forms of agriculture and created small communities of people. People settled in one place and began to trade for work. What do you think life would be like if people from these two eras didnââ¬â¢t start the things they did for us?

Explain and Assess Descartes Trademark Argument
Explain and Assess Descartes Trademark Argument Descartes Trademark Argument came about when Descartes was in the process of trying to build up the knowledge he himself can know a priori (without experience) through pure reason. When doing this be began to think about where his idea of God came from and eventually Descartes concluded that the idea of God comes from God himself and he explained this through the Trademark Argument. The argument is an a priori argument meaning before experience.This sort of argument is the type that philosophers usually prefer because, unlike a posteriori or after experience, the evidence is not so open to interpretation because anyone could dispute the true meaning of an experience but its far more difficult to do that with pure reasoning. The origins and foundations of the Trademark Argument lie in the Causal Adequacy Principle. This states that any cause of something must have at least equal or greater properties than its effect, so in short it means that every cause must be sufficient enough to create the effect.For example, to break a window, the cause must have enough power in the speed and weight of the object in order for the window to shatter. So in this case a fly wouldnââ¬â¢t cause the window to shatter just by flying into because it does not possess greater or equal properties however a flying brick will possess these properties so the window can shatter. Descartes then applied this theory with out ideas. Ideas must be caused by something, but this something must have at least as much reality as the idea themselves.A complex way of saying this would be ââ¬Å"Something (A) cannot exist unless it is produced by something that contains either formally or eminently everything to be found in (A). â⬠To possess something formally is to possess equal properties while eminently is to possess properties greater. Letââ¬â¢s look at this with an example. Ideas of Angels can be made up ourselves just by using our ideas of material things and God. The idea of Angels, which is far greater than any sort of human, but not as great as God, can be thought of as a lesser version of God himself.Descartes was sure that these ideas existed in his own mind however he could not work out if they represented anything else in the real world even if he is led to think that by his instincts. Descartes believed that his ideas had degrees of ââ¬Å"objective realityâ⬠so what they represent can be measured in terms of perfection. These ideas canââ¬â¢t be more perfect or contain more reality than the things that caused them so we cant be the cause of our ideas of God because we arenââ¬â¢t perfect enough to be able to do it even if we are the cause of other ideas such as substance which we cant be sure exists outside our own minds.So, if we canââ¬â¢t be the cause of our idea of God, who can? This can only be answered in one way for there is only one being, according to Descartes, that has at least as muc h perfection as God and that is God himself. So for us to have this idea of God there must have been a God to put it in us in the first place. As Descartes described it, it is ââ¬Å"the mark of a craftsmen stamped on his work. â⬠This can be simplified by using a series of points to structure the argument.The cause of anything must be at least as perfect as its effectMy ideas must be caused by somethingI am imperfectMy idea of God is of a perfect being soâ⬠¦I cannot be the cause of my idea of God andâ⬠¦Only a perfect being could cause such an idea soâ⬠¦God (a perfect being) placed the idea within us and exists.That is the argument in its simplest form. Over the many years since Descartes revealed his findings in his work ââ¬Å"meditationsâ⬠there have been many supporters and backers of the argument, most of whom are rationalists who as explained before, like the a priori style of the argument.Other supporters we can assume could be major religions for exampl e, such as Islam which would share the same view as Descartes that our idea of God is innate the implanted within us by God himself which can also be seen as a major strength of the argument. So, Descartes believes he has proved that in order for us to have the idea of God as a supremely perfect being it must be innate within us and must have been placed in us by God himself. However there are many critics to this argument which must be considered in order to assess the argument.Firstly, many philosophers have encountered problems with the Causal Adequacy Principle. Descartes considered this principle true for many reasons, one of the main ones we think that he believed in was you cant get more out of the effect than what was already in the cause, otherwise it would be something for nothing. This however may not be true because there are examples in the world which we can see as having more in its effect than what was in the cause. One of which is can we not light a large bonfire ju st with the aid of one match? Also can we start an avalanche with just the sound waves from one whisper?There are many other more scientific examples such as Chaos Theory, Quantum Physics and also Evolution. In the case of evolution, single celled organisms evolve into more complex beings just through the passage of time, once all life on earth was just single cell organisms but now there are millions of different species all more complex than what came before. Hume also criticised the causal adequacy principle by saying we cannot determine the cause of anything by looking just at the effect. Can we know what caused a window to shatter before inspecting the evidence to find the cause within?All we know it must have been big enough with enough power behind to smash through the window but we cant even know this a priori. Hume said that we learn a posteriori that for a window to shatter it must have been caused by a large object with lots of power behind it. From this Hume seems to sug gest that to know what actually caused our idea of God we much observe its cause. Hume also said that even if the principle is correct then how could Descartes assume that the principle can just be transferred from physical things to ideas without it changing?However there are philosophers who have defended the principle stating that lots of rules have exemptions and why, if a rule does need exemptions which were not originally set out, is it immediately untrue. Things such as evolution, chaos theory and my examples of lighting a large bonfire with a single match and causing an avalanche with a whisper may just be exemptions to the rule however it still applies to many other things. Some philosophers have also criticised Descartes for defining his idea of God and an incoherent God. For example, Descartes describes God as being Omnipotent, meaning that he is all powerful.This would seem to satisfy many peoples ideas of God however on close examination it is indeed incoherent. To illu strate this I shall use a paradox which undermines Godââ¬â¢s power. Can God create a rock that he himself could not lift? Either way one thing he can not do for if he can create the rock then he canââ¬â¢t lift it but if he cant create the rock there is still something he cant do. This paradox suggests Descartes idea of God is flawed and imperfect so a perfect being can not be the only possible cause of the idea according to the causal adequacy principle.From this we can deduce that its far more likely that Descartes himself created this imperfect idea rather than a perfect being. The final criticism I shall look as it one formed collectively by the arch-rationalists: empiricists. This group of philosophers would consider themselves to rival rationalism as they believe that the mind at birth is blank and we gain all our ideas from experience, not reason or innate ideas. Hume, one of the leading empiricists, amongst others argued that we observe qualities in other people and so recognise there are degrees of certain qualities such as knowledge, power and benevolence.With these ideas in our head from the experiences we have had of other people, we can then extend these qualities until we arrive at infinite knowledge, power and benevolence. This way we have arrived at the idea of these things joining and making a perfect being with infinite qualities however we have arrived through it in a much less perfect way than through God. If this is correct then the origin of our idea is not innate and certainly not caused by God but just us manipulating what we have experienced to suit our needs as imaginative human beings. In conclusion there are many strengths and weaknesses to Descartes Trademark Argument.It is a compelling argument to follow because of the way it is structured and how it sets out to explain out idea of God in an untainted way, free of what can be misleading experiences and just work it out through the power of reason however once examining the po tential problems that have arisen since Descartes time it would be difficult to believe the argument is the truth, and for myself it is incredibly difficult to believe in it knowing that there is an equal and possibly more valid reason why we have an idea of God, as explained by the empiricists.

Distribution Essay Example | Topics and Well Written Essays - 500 words
Distribution - Essay Example tury old strategy of independent dealers to a reduced number of jointly held super stores, thus reducing competition among the dealers and shifting the focus to competing with the other automobile dealers (1). In 2005, the Ford unified its Ford and Mercury Lincoln division to strengthen its marketing, sales and service, in the face of growing competition. (2). Therefore in the last decade Ford has demonstrated an urge to adapt to the environment in which it functions. These changes have not given Ford the boost it needs. Ford needs to be more innovative in its changes in the distribution and sales strategies, in keeping with revolutionary change that it brought about in the early 1900s through mass production assembly lines (3). So what is the innovative distribution strategy that Ford can consider? A look at its web site provides a possible solution. In its web site Ford offers a prospective customer the means to navigate and find out the range of products and accessories offered and the possible cost of a product with a variety of accessories and financing facilities. In short the customer has all the information he needs to make the purchase, but now has to go to a jointly held super store and place his order. In case Ford were to make use of the Internet and sell directly it would be making use of direct selling strategies. No doubt this would be against the grain of traditional sales and distribution in the automobile industry sector, which has relied on indirect dealer based sales. There is no market intelligence to suggest that Ford is considering such a change, but then maybe such an innovative change in the automobile sector would be to the advantage of Ford. The reason for this suggestion is the example of Dell Inc. Dell changed the way in which business enterprises have viewed direct selling strategies and the use of the Internet for sales, through its successes in the computer and peripherals market. This remarkable direct-sales model was the result

Cause and Effect - Essay Example Global warming is the rise in earth temperature mainly due to its inhabitants and their activities. On average 7 billion tons of carbon di-oxide is emitted into atmosphere by various activities. It not only threatens human beings, but also animals and fertile land. Gases like carbon dioxide, methane are main contributors to this nuisance(Ham et al.,1993) Most of the sunlight is reflected back from earth, but the presence of these unwanted gases prevents its flow back to outer space and consequently re-reflected on to the earth. Use of chemicals and dumping of industrial waste into the sea are the main factors to this evil cause This rise in temperature causes melting of polar ice caps, rise in sea levels, floods, killer storms, droughts, extinction of species. Coral reefs are at a direct threat from global warming, various skin diseases and cancers are gifts of global warming Bibliography : Ham, J , L H. J. M. Janssen, and R J. Swart. Non-co?

Servant leadership Essay Example | Topics and Well Written Essays - 500 words
Servant leadership - Essay Example Students shall receive desirable educational quality with the support of such control system. On the contrary, this system possessed certain loopholes. Firstly, no principal would state that their students were provided with lower quality of education. This indicates all teachers are given a rank of 5 on the grading system (Daft, 2013). Personal feedback given by master teachers cannot be considered as accurate. It is recommended that centralized external agency should exhibit operations related to feedback control system. Personnel needs to be hired who can evaluate efficiency level of teachers in context of subject area outside their expertise. Teacher grading system forms an integral component of feedback control system. Master teachers and principals were the key personnel involved in such grading system. Teacher evaluation system is important when there is a need to analyze performance of students as well as teachers. Feedback control system highlights contribution of teacher towards a system. Student learning progress is dependent on accountability of teachers. Grading system is an essential part simply because it helps in determining position of a teacher in educational system with respect to others. Master teachers and principal needs to cover wide set of areas in order to grade a teacher. Feedback system can operate efficiently only when a framework of grades or results is provided. This framework outlines performance of teachers over a specific time period. Perfection exhibited by teachers can be portrayed through such grading system. Accuracy is a critical element in the entire evaluation process. Principals are involved in the evaluation process and they might possess long term relationship with teaching staff. This form of relationship tends to violate the process. However accuracy standards can be retained only when state controls the operation through an external agent. Principals who are conducting the procedure also need to be
The novel The Awakening by Kate Chopin Essay Example | Topics and Well Written Essays - 1250 words
The novel The Awakening by Kate Chopin - Essay Example The novel "The Awakening" by Kate Chopin Thus, in the novel, the author portrays the character of Edna who suffers from gender inequality, isolation, suppressed sexuality, racial discrimination, marital problems, motherhood and social customs. The reader can analyze various topics such as gender crises between Edna and her husband, Ednaââ¬â¢s attitude towards motherhood, suppressed sexuality in Ednaââ¬â¢s character, marital problems between Edna and her husband, social systems and racial issues that are depicted in the story in a structured way from a feminist perspective. Literary critics have often remarked that Kate Chopinââ¬â¢s novels have inspired the readers to find the glimpses of early feminism in 19th century American society. The whole novel describes the survival of Edna in a male dominating society that never admits women as equal to men. Feminist ideologies and theories always argue for female existence and survival. As Brown comments; ââ¬Å"Some feminist argue that the sociology learnt today is socio logy of men stating men point of view and therefore the theories and ideas given are biased with the absence of women based theories and ideasâ⬠(Brown, 2011). Kate Chopinââ¬â¢s The Awakening provides some elements of feminism through the afflictions and awakening of the protagonist Edna. The story is based on the Pontellier family who come vacationing on Grand isle near Gulf Mexico. The Pontellier family includes Leonce Pontellier, a businessman, his wife Edna and their two sons. Considering the identity crises faced by Edna in the novel The Awakening one can clearly identify the underlying elements of feminism and feminist perspectives in the novel. Ednaââ¬â¢s cry for independence and her fight towards male dominating society for existence always inspire the reader to create a feminist perspective. The protagonist Edna Pontellier is struggling to reconcile her ongoing unorthodox concepts on femininity and motherhood with the background of prevailing social attitudes. Th e problem of gender in equality is visible in Kate Chopinââ¬â¢snovel. Gender and awakening sexuality have shown their importance as underlying themes in the novel The Awakening. In Launceââ¬â¢s opinion women have no independence, no personal self realization, and she must live only for men. He complains that Edna is not well in her womanly duties and act as an irresponsible mother. Here the man shows extreme male chauvinism in its zenith. His never ending frustration and anger against Edna reveals his intolerance. During the time of 1800s, American society had believed that there was a definite disparity between the sexes. In this historical perspective one can see that man is considered as active, dominant, assertive and materialistic than women. Expected to act their personal duties and responsibilities for the health and happiness of their family members, the women in 18th and 19th century American society were blocked from searching the satisfaction of their own personal n eeds and desires. The eighteenth century American society, on the other hand, attributed its willingness to consider women as individuals who have some domestic duties and responsibilities. In Kate Chopinââ¬â¢s novel reader can find a shift in Ednaââ¬â¢s character and attitudes; however, the society often fails to admit her new status. Edna creates an image in her mind about her freedom. Analyzing her conversation between Edna and Mademoiselle Reisz reveals this idea. Mademoiselle Reis

Societys Fascination with Reality TV Essay Example | Topics and Well Written Essays - 500 words
Societys Fascination with Reality TV - Essay Example Watching a standard TV program is like escaping into a world of fiction and fantasy, where the shocks and jolts that are associated with real life may sometimes be absent. But reality TV offers the lure of so-called truth. It portrays life as it happens, with all its disappointments, hope, anxieties and unexpected events, as well as its mundane, daily grind. The fascination of reality TV for the viewer is in gaining insight into the fears, dreams and expectations of real people. Reality TV programs focus on ordinary, working and middle-class citizens, so it becomes easier for viewers to identify with the characters. To some extent, the fascination for reality TV may also lie in the fact that participants reveal some of the most intimate aspects of their lives. For example the Celebrity Big Brother TV show in the UK where celebrities are asked to live together without contact with the outside world and satisfy certain conditions (www.tv.com). Such programs offer viewers the opportunit y for a voyeuristic look into other peoplesââ¬â¢ lives, while for the ones participating in the programs, the focus is a narcissistic one. With the onset of more and sensational kinds of programs on TV, reality TV which attempts to compete with it, offers an equal amount of shock value but drawn from ââ¬Å"realityâ⬠, which packs a bigger thrill for viewers as compared to standard TV programs, where viewers are aware that the events are fictional or doctored up in some way. For example, TV shows like ââ¬Å"The Bold and the Beautifulâ⬠and ââ¬Å"Dynastyâ⬠are enjoyed by viewers, but they are aware of the fictional content of these programs. Reality TV, however, does not represent ââ¬Å"fluffâ⬠in any sense of the word. In some instances, it may offer valuable insight into the fears, perceptions and feelings of actual people and viewers are irresistibly drawn by the lure of participating, even temporarily, in other peoplesââ¬â¢ lives.

GETTING FINANCING Essay Example | Topics and Well Written Essays - 1250 words
GETTING FINANCING - Essay Example As the name suggests, debt financing is borrowing money from some financial institutions, usually a bank, which you will have to repay after a certain period with interest. Entrepreneurs may borrow money for short term, which means for less than a year. Usually short-term loans are for financing working capital requirements, operational activities, filling the gaps in accounts receivables and inventory (Horne & Wachowicz, 2008). On the other hand, long-term loans, which are for more than one year, are usually the ones that entrepreneurs usually look for to finance their assets, capital, land, buildings, machinery and other costs of starting a business venture. Clearly, debt financing has certain advantages. Firstly, the interest that is paid on these loans is tax deductible thus providing a tax advantage (Bygrave & Zacharakis, 2010). Secondly, as we will see that equity financing provides a part of ownership in the business to its financers, however, the same is not the case with debt financing. Lenders, unlike shareholders, do not get any ownership in the business and thus the entrepreneur retains the sole control of the business (Shim & Siegel, 2008). Thirdly, the entrepreneur usually will get many options with regard to the maturity time and the amount of interest payable per month or per year. Lastly, compared with equity financing, debt financing is less hassle and less time consuming, whereas it may take months for someone to appear on a stock exchange list and getting enough shareholders (Brigham & Ehrhardt, 2008). However, the disadvantages of debt financing are significant as well. Firstly, unexpected changes in interest rates due to economic downturns, at times, create a disaster for borrowers (Horne & Wachowicz, 2008). Moreover, even if these economic downturns of macro environment events fail to alter the revenue and

Moving from organisational employment to self-employment Assignment
Moving from organisational employment to self-employment - Assignment Example Therefore, Deborah and Yasminââ¬â¢s career could be described as internal, that is, subjectively constructed by the individuals themselves. For instance, in the case of Deborah, she envisioned a career that she would be able to attain professional growth and at the same time provide high-quality medical care and personal attention for her patients. However, after the hospitals became more focused on financial gains than on quality service provision for patients she became disheartened. As a result, she decided to start her own nursing home where she could practice what according to her is ââ¬Ëreal nursingââ¬â¢. Hence, her career decision was based on the feelings, opinion and perspective about the value for high-quality healthcare and personal attention for patients as opposed to business-like healthcare. Similarly, Yasmin did not actually plan where she would work or what she would do, but all she envisioned was a continuous career development process that would involve acq uiring knowledge, a range of skills and experiences, and the applying these to various employment contexts. This is why she got fed up with her position at the local authority when she realized that there was no room for development and enhancement of her career, for example, she felt marginalized and powerless to make any policy changes. Therefore, her decision to go enroll for Masters course and eventually start her own consultancy firm was all based on her feelings and opinion that as an employee of the local authority she was not gaining any professional growth and career achievements. Moreover, she felt deskilled instead of gaining a range of skills, and the reason according to her perspective was that the local authority was highly politicized. Question 2 Career anchor is an individualââ¬â¢s self concept that consists of his/her basic values, talents and abilities, and perception of needs and motives with regard to their career. Schein identified 8 career anchors, which are security, independence, technical-functional competence, entrepreneurial creativity, service to cause, general managerial competence, pure challenge, and finally, lifestyle (Schein, 1996). It is clear these career anchors to some extent apply to Yasmin and Deborahââ¬â¢s accounts. For example, Deborahââ¬â¢s career is driven by service/dedication to cause. This is because she is determined and believes in provision of quality healthcare service, as well as personal attention of patients. Thus, her career is fulfilled by helping and satisfying the needs of other people. Deborahââ¬â¢s career is also driven by independence/autonomy whereby she would prefer to work under her own steam and rules to attain career achievements. Likewise, Yasminââ¬â¢s career is also driven by Scheinââ¬â¢s career anchors to some extent, for example, she could be described as general managerial competence. This is because she is the kind of person who likes to deal with other people, thrives at responsibility and problem-solving. In addition, she values the concept of home-life balance, as well as personal time, thus, her career is driven by lifestyle career anchor. This can be clearly understood by her statement, ââ¬Å"I mean there is work life, and there is the rest of your life, and there are your childrenâ⬠(Gallos, 1989, p.273). Question 3 Galloââ¬â¢s quote resonates with Yasmin and Deborahââ¬â¢s story because it touches on several aspects that these women encountered during their career life.

The drunkard Essay Example for Free
The drunkard Essay Develop the five-paragraph essay BEFORE you write so that you know Where you are going. The Use of Irony and Humor of The Drunkard In the story, The Drunkard the author Frank OConnor uses a point of view to primarily reveal humor and Irony. In the story, OConnor uses first person point of view. First person point of view is told through the eyes of the main character in this story. The main character is named Larry. Larry is a young boy who has to go along with his father one day to a funeral. Larrys father Mick Is the person referred to as the drunkard. Larry seems to know what will happen when he goes with his father but Is hoping that his father might consider his presence and not drink. Since the story is told through little Larrys eyes and thoughts the reader mainly focuses on how Larry feels about his dad being a drinker. The Irony and humor that is found in human nature is revealed through Larry, first person point of view. and what happens on his outing with his father Mick. Irony, the incongruities between the expected and actual results of events and humor, the quality of being laughably ludicrous are interweaved in this story. In the short story, The Drunkard Frank OConnor uses tlrst person point ot view to reveal the humor and irony that is created in this musing story. Humor is seen many times In the story after Larry and his father Mick reach the bar following the funeral. Larry is thirsty and takes a drink of his fathers beer. Larry finishes his fathers drink and becomes drunk afterwards. While this Is occurring his father is talking away with a man named Peter Crowley who is also a drinker. When Mick realizes Larry is drunk he knows he must take him home immediately. This scene is described as, They all stopped gabbling to gape at the strange spectacle of two sober men, middle aged men bringing home a drunken mall boy with a cut over his This could not be better told than through the eyes of Larry who at the time is observing all he sees happening around him. Two usually drunk men carrying home but a young boy who Is not sobers enough to walk. This humorous scene described by the main character reveals more enjoyment because little Larry is the one who is drunk. It is also a bit ironic that the two grown men are carrying a drunken young boy home and it Is not the other way around. Larry is watching all the people around him and knows how ridiculous he must look In between the arms of his father adepter Crowley. The humor Is revealed in an entertaining way from the first person point of view because of the situation the main character is in and how he is describing it. t Of2 Irony seems to occur In a Tew Instances since Larry Is settlng up tne reader wltn certain expectations. Larry tells us how his father is and knows exactly what will happen after the funeral. His father will wind up in a bar drunk like he had been described doing since his best friend passed away. Larrys first conclusion about the circumstances that are likely to occur is, l know I might have to bring him home, blink runk, down Blarney Lane, with all the old women at their doors, saying: Mick Delaney is on it again (302). This is Larrys prediction to how the day would end up. To the readers hilarious surprise, this is not what happens. Larrys thirst at the bar gets him in to an unusual situation and bewilderment from the liquor he has drunk. Larry as he realizes he is drunk says to himself, But, drunk and all as I was (301). both the Larry and the reader are surprised by this ironic event. Larrys prediction is reversed. He no longer has to take his drunken father home down Blarney Lane. Now Larrys father has to take Larry home blind drunk. The twist of events that Larry the main character is going through mainly reveals the irony also in a more humorous way. Humor through the eyes and words of Larry, the main character, provide the reader with more enjoyment as his day continues. As the men carry Larry by the arms he knows he is going to stroll down Blarney Lane drunk. So as Larry is proceeding down the lane he cries out to the women laughing, Ill make ye laugh at the other side of year faces if ye dont let me pass Go away ye bloody bitches Take care or Ill come back and show ye! (302). this scene described by Larry is very comical. He knows he father usually passes down this same lane drunk but does not get to realize what it is like until now. Its especially worse for Larry because he is not a grown man yet who is allowed to drink. It is ironic also because Larry never thought hed be the one walking down this lane drunk after the funeral. The humor being revealed is more amusing through the words of Larry who is telling the story from the first person point of view.

SQL Injection and Buffer Overflow Attack Detection
SQL Injection and Buffer Overflow Attack Detection CHAPTER ONE INTRODUCTION This chapter discussed about research requirement for this research. It discussed briefly the research background in section 1.1, problem statement in 1.2, research objectives in 1.3, research questions in 1.4, scope of research in 1.5, research elements in 1.6 and research significant in 1.7 1.1 Research Background The internet which is a free, supportive and self-sustaining facility reachable to hundreds of millions of people worldwide, have become one of important communicationââ¬â¢s medium today. The greatest widely used part of the Internet is the web or World Wide Web (WWW). The Web uses the Hypertext Transfer Protocol (HTTP) to convey data through the Internet as HTTP is a well-known language over the Internet. There is a Web Browser that acts as the main door to the Internet if user wants to view the web pages in different websites. Web pages is a document that may contain text, videos, sound, images or any multimedia components created in Hypertext Markup Language (HTML). In addition, to make the process of searching specific web pages easier, there is Uniform Resource Locator (URL) where it standardized naming convention for addressing documents available over the Internet or Intranet. As Internet become more and more significant, there are some individuals identified as hackers that have the ability to interrupt the peace of using Internet. For that reason, network security is required. Network security emphasis on securing networks from any violence or exploit especially from hackers and typically handles by network administrator on each organization that applies security policy. Thus, to ensure the three main goals of security which are integrity, availability and confidentiality is guarantee, network security become the main role to some kind of vulnerabilities in web application. Vulnerabilities can be referring as the flaws where attacker can take benefit by exploiting it to gain unauthorized access to their target. There are two of the most common web application vulnerabilities that exist in a web application are Structured Query Language (SQL) Injection and Buffer Overflow (BOF). SQL Injection is an attack in which the attacker inserts SQL commands into form or parameter values. It exploits the use of SQL query in the application. SQL Injection has become a predominant type of attacks that target web applications. The Open Web Application Security Project (OWASP) ranks it on top among the Top-10 security threats. Buffer Overflow is an exploit that can make the memory allocated to a certain application become massive. For example, an application expecting a five-digit postcode therefore the programmer only allocates enough memory for the perimeter. If an attacker enters more than five digits for example hundreds of digit, the application will end up using more memory than what it should. As of September 2010, 12 of the 20 most severe vulnerabilities ranked by US-CERT were Buffer Overflow related. There are a lot of web application vulnerabilities detection scanners existing in Internet. Either it free source or need to buy, there are more or less problems faced by these tools. The common problem meet by some of the scanner are false positive and false negatives. A false positive is when there is an error whereby a web application tested for is mistakenly found the vulnerabilities which actually there is none. Meanwhile, false negatives are the scanner does not found any vulnerability in a web application and telling user that the web is secure. However, actually the web application may have some vulnerability. Thus, by proposed a method for detecting the web vulnerabilities through searching for the suspicious and defined web vulnerabilities criteria, it will help the web application administrator to take a look and always standby in secure mode to avoid and secure mode for avoiding any attacks from the attacker. 1.2 Problem Statement Usually developers of a web application does not realize that their web application have vulnerabilities. They only realize it when there is an attack or manipulation of their code by someone. This is normal as in a web application, there are thousands of lines of code so, it is not easy to detect if there is some mistakes (Houghton, 2013). Nowadays lots of new hacker are born as the tools and tutorials are easier to get. According to Dougherty (2012), even though SQL Injection is very easy to protect against, there are still large numbers of the system on the internet are vulnerable to this type of attack because there will be a few subtle condition that can go undetected. Besides, in Buffer Overflow, although many methods have been proposed to address this problem, it mostly very high overhead involves considerable additional resources (Zheng, Zhou Liu, 2015). Therefore, a detection method for detecting the SQL Injection and Buffer Overflow while producing minimum false positive a nd false negative was proposed. 1.3 Research Objective There are two objectives that have been achieved in this dissertation: To construct a detection method that can detect SQL Injection and Buffer Overflow attack in web application based on acknowledged features and characteristics of the vulnerabilities. To evaluate the performance of proposed method in term of accuracy and efficiency by conducted two sets of experiments under laboratory testing environment. 1.4 Research Questions There are four research questions that have been addressed in this dissertation: Is it possible to employ a dynamic method for SQL Injection and Buffer Overflow detection in web application? What are the criteria used to detect SQL Injection and Buffer Overflow in the proposed detection method? What is the evaluation metrics used to measure the performance of the proposed detection method? How to measure the accuracy and efficiency of the proposed detection method? 1.5 Scope of Research This dissertation focused on the web application vulnerabilities which are more specific on SQL Injection and Buffer Overflow. This dissertation limited to: Detection of web application vulnerabilities which are limited on: SQL Injection Buffer Overflow A number of vulnerable websiteââ¬â¢s URL collected from: http://www.thetechnism.com/ http://pastebin.com/ For detection of web application vulnerabilities of SQL Injection and Buffer Overflow, the criteria used are: Get the URL of website Tokenize the URL Match the pattern with the matching criteria based on Boyer-Moore Algorithm Get the web application vulnerabilities The evaluation metrics that used in this dissertation are accuracy and efficiency 1.6Research SIGNIFICANCE There are two significances of this dissertation: This dissertation able to provide a method that can detect SQL Injection and Buffer Overflow attack based on Boyer-Moore String Matching Algorithm. This proposed detection method also able to generate the report regarding the level of vulnerability of the web application. The proposed method can assistance the web application developer or administrator to take any extra action to protected their application from being attacked by the unethical person outside the network to SQL Injection and Buffer Overflow attack.
