The Book Spiritual Mothering The Titus 2 Model For...

Introduction Today there are many Christians that do not know how to develop and strengthen their faith. Their faith can be shaky because most times when hard circumstances and trials come their way then they lose faith that God will bring them through. The way to help people strengthen their faith is mentor them. Mentoring is a way to spend time consistently with someone to keep them accountable in their walk with the Lord and understanding what time with the Lord looks like. The book Spiritual Mothering: The Titus 2 Model for Mentoring Women is a book that helps Biblical women know their role in mentoring other women. It helps women to understand the model that they should use in mentoring other women. This book focuses†¦show more content†¦After describing the reference point of spiritual mothering Susan Hunt then describes the fact that it is a life purpose. The author describes a Biblical woman’s life purpose as glorifying God. A Biblical woman should be living their life to glorify God in everything that they do, which includes when they mentor other women. In order for a Biblical woman to follow the mandate of mentoring based on Titus 2:3-5, she must be obedient to God throughout her life. That does not mean it will be easy, but obedience to God is essential for any older woman who is trying to mentor other women. It is essential because there would be no reason for women to mentor others if they are not following God and being obedient to what He has called them to do. After describing the life purpose, Susan Hunt then goes to tackle the importance of sound doctrine. Sound doctrine refers to teaching that is in ling with Scripture and God’s commands. After covering the mandate, the author moves next to the model. The Model The very first aspect of spiritual mothering that Susan Hunt addresses is that of nurturing and building the relationship. She writes that, â€Å"Spiritual mothering is impossible apart from a relationship.† Building a relationship with someone that an older woman is mentoring will not always be easy because it requires work. The work of building the relationship is necessary though

Lehman Collapse Capital Markets

Question: Discuss about theLehman Collapse for Capital Markets. Answer: Introduction: Brief Description Lehman Brother collapse in 2008 was considered as one of the most tragic events of failure among financial institutions. Before, it collapse the company was considered to be the fourth largest investment bank in America (Iminds, 2010). Began in 1844 by Henry Lehman, Lehman Brother was a small grocery and dry goods store, after two decades they traded cotton, and later Henry Lehman moved to New York to establish a New York Cotton exchange firm. After, the occurrence of this events Lehman went on with this road of success to be able to establish the fourth largest America investment bank. The main areas of business for Lehman before the collapse include; typical investment banking as well as participation in equities, capital markets, investment management and fixed incomes (Iminds, 2010). Their investment banking process could provide financial services such as mergers, underwritings, acquisitions and security issuing. They had also invested globally in fixed incomes, capital markets investment management parts. But, the main revenues of the firm came from fees derived from size of transaction or services being provided by the firm to their customers (Lee, 2009). Despite all these the firm had survived all traumatic events ranging from world wars to the great depression, but the collapse of U.S. housing market brought the company on its knees. Causes of Failure The following are reasons why Lehman Brother bank collapsed: Poor Assets and Risk Management Here, the old saying of not putting all eggs in one basket tends to have a significance. It is evident that when the housing sector market was at peak Lehman borrowed in excessive and mostly invested all its proceeds in to the mortgage market. But for security reasons subprime loans had granted mortgage to houses that Lehman had already bought. Greed and recklessness became the order of the day as they tried to be leaders in the market for the subprime mortgage backed securities. As of 2006 to mid 2007, they had pursued an aggressive strategy where they thought of expanding into commercial real estate, private equities and leverage lending through their capital (Haas Horen, 2012). Hence, their concentration in mortgage made them vulnerable and sensitive leading to the down fall. Management Problems Lehman brother similar to the great city of New York never slept. Whenever the trading bells rang at the NYS Exchange at four that is in the afternoon, the equity guys just packed up because there was nothing else to be done. Bank debts and high yield debts went till seven. In often instances the traders had a normal looking balance sheet that werent drastic; this is because losses were never loved by Lehman management (Dillian, 2011). Hence, the failure by the firm to acknowledge losses might be reasons as to why the business failed. Fraud As of 2007 the American housing market began to crumble due to the increased numbers of default. Hence, this meant losses for Lehman and hence they were forced to write down billion of dollars as bad debts, which greatly deteriorated their financial position. Hence, they were unable manage their financial leverage and took too much risk (Mcdonald, 2015). For the purpose of hiding their poor financial status they ought to develop the Repo 105 transaction to show that they are still maintaining a positive grading based on the rating but that wasnt the case. Such an act of fraud was also a reason to their downfall. Above are reasons as to why Lehman Brothers collapsed but it is also important to at least try and shows the early signs of their collapse, in this case we will outline the activities that I believe are reasons as to why they collapsed. Activities engaged in that showed early signs of collapse Before the collapse, Lehman Brother risk management team had identified several specific inherent risks in the business that lead to the collapse: Operational risk- this tends to be loss that originates from inadequate or failure by the Lehman internal process, including the responsible people and systems and also the external events that they engaged. Credit risk-the firm also run the risk of loaned counterparty being unable to honour the contractual obligation to the Lehman Brothers. As a result, in the future it escalated the possibility of collapse (Benos et al, 2012). Reputational risk-this tends to be the risk of losing the confidence from customers, public and the government as a result of the unfortunate decisions on the clients selection and conduction of the business. In some way these had an influence in their collapse as they faked their records to remain attractive. Market risk-this tends to be a representation of the potential unfavourable change in the value portfolio of the financial instruments as a result of the changes in the market rates, volatilities and prices. Liquidity risk- this was the risk factor where Lehman was unable to fulfil payment obligations, they also borrowed funds in the markets at certain good regular prices for the purpose of funding actual commitment and liquidating their assets. This initiative came as an early sign of their downfall (Tibman, 2009). Exceeding the Risk Limits In 2007 the firm raised a wide risk limit close to $2.3 billion to $ 3.3 billion, justifying it by the modifying of ways that calculate risk they can support. As of September 2007 it was increased to $3.5 billion and $4 billion in 2008. If risk limit were calculated under same assumptions, it would have been $2.5billion. In making analysis of Lehman Brothers mode of risk management, it tends to conclude that Lehman management in countless times had exceeded risk limits, ultimately exceeding risk policies by margins of close to 70% as on the commercial estate, and by 100% on the leverage loans (Paulson, 2010). An explanation to this is the dangerous behaviour in the compensation system. For attraction and sharpening the minds in the industry, they should reward the most revenue generating employee who makes big monetary bonuses. But, the bonus incentives were asymmetric. Implication of Lehman Fall to the International Banking Industry It tends to be perceived that Lehman bankruptcy has some effects on the depreciation in price of the real estate commercial. For instance, when there was liquidatin of $4.3 billion in the mortgage security, it created a sell of in commercial mortgage that was to backed by securities (CMBS) market (Robinson et al, 2009). Some auditors perceive that the collapse of Lehman led to rise of top primary reserve fund. It was the only time since 1994 that the money market fund experienced a drop which was below $1 per share level. Hence, the collapse of Lehman wiped out over $46 billion in the market value. Collapsing of the firm acted as a catalysts to the purchasing of Merrill Lynch by the American bank as an emergency so as to deal with the issue. Loss of Lehman created a loss of close to $48 billion of the receivables in the derivatives that could be otherwise relaxed (Dziedzic, 2010), and a total of $75 billion was destroyed (Dziedzic, 2010.) Could the Collapse have Been Prevented? Iminds (2010) perceives that Lehman collapse could have been easily avoided only if they were proactive initiatives held by the executives to make sure there is effective control of the risk management in their operations. Nuerberger officials had send Lehman Brother executive team some memos suggesting they forgo the multi-million dollar bonus as it created a strong message to investors and employees as the management accountability was decreasing. Hence, Iminds (2010) argues that the collapse of the financial institution could have been avoided only if there was adoption of effective risk management practice in the derivative trading. As of Lehman case they had invested more on the risky derivatives. It is perceived that the main motive of the derivatives was to assist the actors found in the real economy insurer against any risk, but in some cases the derivates trading had crossed the price stabilization and the risk management speculation. Therefore, if regulators of derivatives had effectively considered this Lehman Brother wouldnt have collapsed. Conclusion It is evident that the failures of Lehman Brother mostly originate from their internal operations, thus a lot of questions have been asked as to whether the interaction of Lehman brother and government agencies had regulations and monitoring of Lehman leading to the fall. Thus, a lot of analyst tend to believe that Lehman bankruptcy had some set off in panic that created a threat to U.S financial system and also the entire global financial system (Mcdonald Robinson, 2009). Hence, after the fall of Lehman a lot of concerns have risen as to what created the failure of the onetime leading investment bank. it is perceived that the questions are currently hard to answer because little knowledge is known of what happened in Lehman. Creating the need of coming up with effective strategies that could avoid an instance where there is collapse of a financial institution (Mcdonald Robinson, 2009). Recommendations It tends to be believed that the bonus system had some encouragement to the management to increase their risk. In most cases, the operational errors and excluding assets in stress test created limitations and over-leverage in the balance sheet which greatly fuelled the bonus aspect (Dziedzic, 2010). Any banking system that has no bonus system tends to be unthinkable for many, as it is a way of decreasing future bonus in relation to risk taking in the building of risk aversion parameters as found in the bonus criteria. For instance, no bonus is to be rewarded if the test shows large risks even if the profits appear big, though it needs stress testing so as to be executed independently. It is perceived that a lot of market risk could be avoided only if Lehman hadnt focused on investing heavily on the correlated assets. Here, the credit crunch hit large because of subprime crisis as it affected both the commercial real estates and leverage loan assets (Hass Horen, 2012). Thus, the ties between the assets was struck quickly by losses created in the fronts. Thus, the consequences greatly hit the chain making it less fatal if the bank was operating more diversely and no focusing mostly on the portfolio. They also made themselves vulnerable to the liquidity risks. Since, they depended on the short term funding for long term investment, which was a fatal mistake as credit market dried up and there was no illiquid assets. As of 2008, there was no government agency that had sufficient authority to compel Lehman operation in the best that made them avoid the viability of loss (McDonald, 2015). Hence, the need of a solution regime where analogous establishment of the failing banks took place, so as to avoid options in the future between baling out a fail, and systematic critical firm or allowing the disorderly bankruptcy. Hence, development of such a regime was expected by the global banking industry to protect the economy as well as maintaining that there is an improvement in the marketing discipline through maintenance of failing firm shareholders and creditors losses and replacement of the management. It is perceived if they had done adequate stress testing and simulations, they would not have changed their focus from brokerage and financial services. The high leverage ratio affected the other risks adversely making downfall fast and unstoppable References Jacoby, J., Karzis, M., Kroft, S., Valukas, A. R., Lee, M.

Representations of Global Femininity/Masculinity in Contemporary Media

Introduction The change in time and events from a conventional world to one that is sophisticated and modern has been accompanied by changes in representation of masculinity and femininity. This is with regard to how the contemporary media represents both man and woman and its position on this.Advertising We will write a custom research paper sample on Representations of Global Femininity/Masculinity in Contemporary Media specifically for you for only $16.05 $11/page Learn More Contrary to the conventional style of representation where the woman was overshadowed by the man, she is now gaining representation in a powerful and autonomic manner that reveals her self-confidence. This paper will bring into light the changing, as well as the adamant phenomenon of representation of masculinity and femininity by the contemporary media. How Contemporary Media represents Masculinity and Femininity The great shift to contemporary visual media has been accompanied b y a change in the representation of women. According to the contemporary media, the woman is faced with a lot of responsibilities which she must see to it that they are all handled accordingly. As a result the media has brought out the woman as one who is faced with a lot of challenges, making it difficult for her to live up to other people’s expectations. However, it has been shown that, amidst their dilemmas, women resort to traditional intervention with regard to femininity for a solution. Different articles will explain the different ways which women act in relation to femininity. Men on the other hand have always taken up the authoritarian role that depicts power and strength (Leavy, Gnong and Andrea 261-292). Typical images of the modern woman, for instance pop stars like Britney Spears and Jennifer Lopez represent a unique kind of femininity. In this kind of representation, the woman is independent and entitled to her own life. This shows the liberation of women while compared to what was previously the perception of femininity where the woman stayed at home to look after her children and husband. Now, the woman has become more educated and liberated, but the main theme of femininity that has not changed a single bit is beauty. Contemporary media has given the picture of a woman as one who is adventurous, and in so doing has continued to encourage this kind of behavior. This woman is able to capture the best man who is sexually desirable. She then retains this man as long as he is interesting. This kind of woman will also be seen pursuing a great career at the same time. This is a demonstration of the change in representation of femininity in contemporary media which in other words can be considered to be cosmopolitan. It is very different from the traditional method of representation of women as wives and mothers. It is therefore clear that great changes have occurred and transformed the perception of women by the media (Leavy, Gnong and Andrea 261-292).Advertising Looking for research paper on gender studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More The representations of masculinity and femininity by the media are constantly changing and so are the perceptions. The change in representation is what leads to the change in perception as the media is very powerful in influencing people’s attitudes. Previously, the woman was represented as a submissive and obedient wife and mother. Currently, this is not the case as women strive to gain equality with regard to gender. Men on the other hand were represented as having power and authority over the woman. This representation has however changed as men have turned out to become violent so as to acquire hegemony, which is linked to masculinity (Andersen and Gray 446-450). Contemporary media may have a negative impact on the representation of the woman and associated femininity. For example, the implications of the media on porn ography tend to have a negative impact on the women as opposed to men whose hegemony is very evident. The contemporary media fosters growth and availability of pornographic materials. However, as pornography grows, so does its violent nature that is entailed in its content. The video, which is the latest kind of contemporary media, shows very sad sexual fantasies. The perception brought out by this kind of representation is cruelty and unfriendliness to the femininity of women but on the other hand, encourages dominance by the man. This dominance has been portrayed through activities of sexual molestation (Andersen and Gray 446-450). Femininity and masculinity are two different kinds of images which are seen to vary considerably. The femininity of a woman in contemporary media is shown through pictures that bring out the beauty and attractiveness of the woman. The appearance of a woman in enhancing her femininity in certain jobs especially in the tourism industry is very important. The femininity of a woman is portrayed by her feminine appearance. A feminine appearance requires the woman to make her hair, wear make-up and suitable uniform that enhance her femininity. This is opposed to men whose attractiveness or masculinity with regard to the physical body is not required for the application or maintenance of a job. Irrespective of the empowerment that women have obtained, the media still maintains a position of hegemony with regard to gender. An example of this is where, irrespective of the masculine women like Cristina Yang in Grey’s Anatomy and feminine males like George O’Malley, conventional gender expectations are very evident, representing either femininity or masculinity.Advertising We will write a custom research paper sample on Representations of Global Femininity/Masculinity in Contemporary Media specifically for you for only $16.05 $11/page Learn More This can be argued from the point that women continue to be attractive even if they tend to drift towards masculinity. On the other hand, the masculinity aspect among men who try to act in a feminine way is dominant thus will persist (Leavy, Gnong and Andrea 261-292). Contemporary media has used the mind-body dichotomy to bring out differences between men and women and associated masculinity and femininity respectively. This aspect of body and mind is seen to create disparity between masculinity and femininity. Masculinity places a lot of emphasis on the mind while femininity is all about the body. A quote from Bartky Sandra â€Å"Woman’s space is not a field in which her bodily intentionality can be freely realized but an enclosure in which she feels herself positioned and by which she is confined† depicts this (cited in Leavy, Gnong and Andrea 261-292). The concept of women’s space is taken to bring out a common idea of enclosed space. It could mean power or lack of power. This space could also be a symbolic rep resentation of the woman’s body as it is perceived to be associated with gender performance. On the other hand, the masculinity of men is not confined to their bodies. It entails attitudes, ability to think and perception. The dichotomy used reveals that as opposed to women, the masculinity of men is more realized by their ability to hold power and think wisely as opposed to a woman whose femininity is in her beauty (Andersen and Gray 446-450). Conclusion The media is actively involved in representation of both men and women in the content of masculinity and femininity respectively. The perception of masculinity and femininity will continue changing for as long the media keeps on changing the representations of both men and women. Despite the changing representations, one thing is for sure, femininity of a woman with regard to beauty can never change. On the other side, masculinity and power are inseparable.

Qualitative Report, 2009 (14), 261-292, Bibliography Component Bibliography 1. O’ Barr, William. Representations of Masculinity and Femininity in Advertisements. Advertising Educational Foundation, 2006. Reason The article by O’Barr on representations of masculinity and femininity, asserts that advertisements that are represented by the media form a strong ground for emulation and reaction by the concerned parties. The relevance of this article with regard to the topic at hand is brought about in its explanation of what is entailed in masculinity and femininity. Masculinity is associated with power, virility, competitiveness, strength and athleticism. Femininity on the other hand is related to nurturance, beauty, cooperation and submissiveness. The article argues that both m en and women indulge in different activities that reveal their femininity or masculinity. The woman will bring out her femininity through her beauty and provocative postures that lay much emphasis on her sexuality. The femininity of a woman is used to show beauty, attractiveness, passiveness and cooperation. Masculinity on the other hand is associated with aggression, power and strength. Among other aspects of masculinity and femininity that will change, the ones mentioned above are inherent as they are used to define the difference between a man and a woman. It is very clear that both men and women have different roles to play in order to show their masculinity and femininity respectively as represented by different kinds of media. It is worth noting the masculinity and femininity begins at birth after determining the sex of a child. The media has been used to enhance this difference by demonstrating the different ways through which a woman can show her femininity. In addition, it has been applied to represent and show how masculinity is manifested in men (O’ Barr 213-221). 2. Millington, Bradley. Learning Masculinities: Youth, the Media, and Physical Education. Queen’s University, 2004. Reason According to the article by Millington, the media is filled with stereotypes about men and masculinity. This is especially true with reference to violent videos and movies. Since time in memorial, man has always been regarded as the greater sex. Contemporary media represents masculinity in terms of violence. Men have been seen to engage in violent and brutal acts in an attempt to bring out their masculinity. This may not work well for the young males as they will adopt this kind of behavior too. In a bid to reveal and show their masculinity, cases of violence against women will continue to prevail for as long the media will place masculinity in close link with violence. This research article is relevant to the topic as it shows how masculinity is represen ted by the media in the form of violence. This raises a lot of concern on how the young males and females will perceive the different representations by the media. The contemporary media is involved in presenting stereotypes on what is entailed in masculinity and femininity. The media presents the woman as one who is submissive and in so doing, embraces culture in the view of femininity. On the other hand the highly upheld and believed concept of hegemony with regard to masculinity is represented. However, the current position of both masculinity and femininity is not that which alienates femininity from masculinity as the search of equality continues to be contentious. This article raises concerns with reference to the perception of representation of masculinity versus femininity by the media. This is because the young people will be greatly influenced by the media to the extent that they will tend to follow what is represented in the media. The media has always been considered to have a very great impact on the people. This comes about due to misunderstanding that revolves around the issue of representation of masculinity and femininity by the media. This is explained by the fact that people are easily carried away by the media and will tend to follow what the media shows regardless of whether it is favorable or not (Millington, 23-45).

Heathcliff and Catherine in Wuthering Heights Essay Example Heathcliff and Catherine in Wuthering Heights Essay Heathcliff and Catherine in Wuthering Heights Essay Essay Topic: Wuthering Heights Heathcliff and Catherine are depicted as soul mates, their love exists on a higher or spiritual plane; they have such a high affinity for each other that they are drawn together uncontrollably. The relationship is portrayed as almost one entity as if the two characters have become united. Catherine pronounces to Nelly ‘I am Heathcliff! He’s always, always in my mind. But as my being’. The quotation epitomises their inextricable love, regardless of separate marriage and physical detachment their souls will always be inseparably linked. Moreover, the metaphor perhaps symbolises eternity, as their love is never absent or divided, their hearts have become permanently indivisible. The use of the exclamative sentence emphasises the passion and intensity surrounding their relationship. Additionally, the repetition of ‘always’ strengthens the sense of perpetual and undying love. In chapter 16, after Catherine’s death Heathcliff echoes Catherine’ s speech to Nelly and he is conveyed as disordered as part of his sole has perished due to her demise. Heathcliff states ‘Oh God! It is unutterable! I cannot live without my life! I cannot live without my soul!’ illustrating his dependence on her, suggesting that her existence is a requirement for his identity and he falls into confusion and chaos without her. It could be viewed that quotation depicts that without Catherine, Heathcliff’s identity is impaired and that is unbearable to endure life without Catherine. Bronte presents Heathcliff and Catherine to be soul mates, she portrays both characters to be reliant on one another for stability and that it would be purely intolerable for one to live without the other. The love between Heathcliff and Catherine is also portrayed as obsessive and all consuming. On Heathcliff’s return to Wuthering Heights, he visits Catherine at Thrushcross Grange. Bronte uses a simile to illustrate Catherine’s obsession with Heathcliff ‘her gaze

The Gulf War from the American perspective Essay

The Gulf War from the American perspective - Essay Example In any case, once thing is clear; the publicly stated reasons of Iraq war were not digestible to many people. This paper analyses Gulf War from American perspectives. George Bush thought that Gulf War may help him to win the presidential election once again. He thought that this war might help him and his party (Republicans) to increase the popularity and hence he may get an easy walkover in the coming presidential election. However, Bill Clinton proved that such beliefs were wrong. â€Å"Clinton successfully made the economy the issue in the next election and managed to win it†1. â€Å"For years Saddam received US support while committing atrocities. His was not the only government committing atrocities. His atrocities were never publicly discussed until he invaded Kuwait†2. The invasion of Kuwait brought Saddam Hussein into the public lime light. It was difficult for America to justify Saddam further. It should be noted that democracy is prevailing in America and Amer ica believes themselves as the saviour of human rights. Under such circumstances, it was impossible for America to stay blind while Iraq was questioning the sovereignty of an independent country. Moreover, many Americans thought that Saddam is trying to become another Hitler. Increased influence of Saddam in the Middle East was not good for the American interests. â€Å"Saddam was repeatedly compared to Hitler. Then he was publicly defied and demeaned. The president said he has "had it" with "Sad'm" Hussein. Under U. S. leadership, the world was mobilized against him†3. America suspected the possibility of another world war unless they prevent Saddam from conquering neighbouring countries. It should be noted that the military power of other gulf countries were negligible in front of Iraq’s military power at that time. In short, many people believe that America attacked Iraq to save the world from the possibility of another world war. Another argument claims that Americ a attacked Iraq to control the oil resources. However, this argument seems to be far from reality since America’s oil imports from Iraq account only 5% of the total energy needs in America. There are plenty of other countries in this world which rely heavily on Iraqi oil resources for their energy needs. â€Å"So oil is not the whole answer. Other possible aspects of the answer include "a new world order," collective security, interdependence, prevention of regional hegemony, and reversal of American decline†4. Even though Iraqi oil does not cause much direct problems to America, it has the potential to cause indirect economic problems in America. If Saddam Hussein had raised oil prices to $27 a barrel, the increase in our import bill would have been about $20 billion a year, or less than one half of one percent of GNP. The greater harm comes when sudden rises depress the economy, but this effect is harder to estimate. Some economists believe that a temporary oil price of $40 a barrel, for example, helped to trigger the recession, which represented a loss of several percent of GNP5. â€Å"U.S. policy toward the Middle East is characterized by an intention to ultimately control the oil there, and keep other powers--not just the Soviet Union, but also Britain and France--away, if not dependent on the United States6. It is a fact that oil resources in America are rapidly exhausting even though the demand for oil increases. The oil needs or the energy

Scholarly paper Scholarship Essay Example | Topics and Well Written Essays - 3750 words

Scholarly paper - Scholarship Essay Example Whether or not a law prohibiting smoking in cars containing minors could be passed in the US would ultimately depend on the law’s constitutionality under the Commerce Clause of the US constitution. The Commerce Clause allows congress â€Å"to regulate commerce with foreign nations and among the several states† and has long been an issue of political and social debate. The Supreme Court’s current standard for determining whether Congress has exceeded its commerce power can be subjective, making it difficult to predict constitutionality of proposed public health laws. However, the court has shown surprising willingness in recent cases to broaden the power of congress to regulate commerce in order to protect public health. Especially to innocent children confined to auto mobiles and who cannot protect themselves, as such a federal law prohibiting smoking in cars containing minors could be found constitutional. Furthermore, if congress were to refuse to take such a law into consideration, it could be possible for states, themselves, to regulate smoking in cars under the dormant commerce clause. This problem cannot be easily prevented by taking simple actions like opening of the car windows. This is because this action can change the direction of the air flow and as a result the smoke gets blown right back into the face of the child. What requires to be done is a law to be passed that prohibits smoking in motor vehicles. This can place stiff penalties to the offenders with the possibility that the parents can lose custody of their children if found engaging in the act. The level of exposure to secondary smoke by children is about 11% in the United States. This study was carried out among children aged below 6 years. It was also revealed that it was the parents who were the main source of exposure to their children, exposure by parents accounted for 90%. There was a new revelation in the research

Persuasive Essay, the Player, All Realities Are Fictitious Essay Example for Free

Persuasive Essay, the Player, All Realities Are Fictitious Essay Our world consists of many realties. Two being commercial, and the other, artistic. A commercial reality is one of indulgence, and pleasure, always aiming to suit those who yearn for it. Artistic reality however, is open to interpretation. This means there are many possible outcomes. One could be saddened or depressed by the reality, and others, joyful. It is because of this uncertainty in artistic realities that the film industry, as well as many other industries, have taken it upon themselves to glorify the truth. It is because of the clashing of these two realities, that reality as a whole becomes difficult to interpret. The statement that every reality is fictitious, is rather bold however. Although in numbers, there are a few people who hold very strong moral and have a sense of quality in what they do. The Hollywood film industry is entirely commercial. Offering little or no interest in writers work that consists of depth, moral and truth. This reality consumes those considered as naive to the industry. Commercial realities are realities that are created by people who want to escape their own and subconsciously create a reality that is deemed impossible in the â€Å"real† world. Commercial realities are attractive to most, because you can experience something otherwise unimaginable. It is us, the audience of massive Hollywood productions, that show true appreciation of films made by producers who show no other interest than creating fictional nonsense and profiting from us . The film making industry is created by artificial characters living paranormal lives that we aspire to have. However, who can jump from a 4 story building and land on the ground with no injury? Who can be stabbed and instantly heeled by only a bandage and continue battling the world with heroic attributes and a vision to sustain â€Å"humanity as we know it† Commercial realities are fictitious, and it leaves us dreaming of a better life, and fantasizing over it. Many of our youth are involved in lives that are run by action, violence, recklessness and stupidity. A contrasting reality to those of commercial is that of artistic. This reality has deeper meaning to it, and value. Artistic reality may be generally defined as the attempt to represent subject matter truthfully, without artificiality and avoiding artistic conventions, implausible, exotic and supernatural elements. Artistic reality is better known as ‘realism. ’ Realism revolted against the exotic subject matter and exaggerated emotionalism and drama of the Romantic Movement. Instead it sought to portray real and typical contemporary people and situations with truth and accuracy, and not avoiding unpleasant or sordid aspects of life. Artistic realities often reject changes wrought by Commercial Revolutions. Artistic realities reveal the truth, which means they may emphasize the ugly or sordid. Artists use their work as a form of expressionism, which is open to interpretation. They see true value in their oeuvre, as they see ordinary, everyday subjects as the depiction of naturalism. Many people attempt to depict things accurately, from either a visual, social or emotional perspective. Theatre Realism shares many stylistic choices with naturalism, including a focus on every day (middle-class) drama, colloquial speech, and mundane settings. Realism rejects imaginative idealization in favour of a close observation of outward appearances. Often artistic realities can be labelled as fictitious. This is due to the majority of society being so consumed by commercial reality that they no longer can differentiate from commercial actually being fake, and artistic as being real. Commercial realities enhance the breeding of money. Commercial values manipulate the very anatomy of a natural, mundane reality. Commercially precious films of ‘reality’ have become the organ grinder’s monkeys of money. They are made to increase the generative value and staying in power of money, the power of money to breed money, to fertilize itself. They are not made to empower people and provide certain value. Artistic reality however, leaves no stone unturned. Realism sees no value in money, and it sees no reciprocal (mutual? Would this be better? ) material possession that could be exchanged for money. Artistic realities merely capture that which is tangible and accurate. Society may attempt to defend themselves by escaping this as it may be deeply depressing. It is the confusion of distinguishing between commercial and artistic realities that ultimately reduces both to nothing but fictitious mumbo jumbo that controls our lives. The difference between the two is huge, however difficult for ‘commoners’, or those not involved in the film industry, to interpret. Whether an individual comprises their lives of commercial or realistic values, these values can be labelled as fabricated or factual. The film industry’s repackaging and misrepresenting the truth to suit themselves is profitable. This profitability is their ultimate ruling guideline. If a film does not provide profits, the film was a total failure, regardless of its realism. Artistic realities are open to interpretation and provide a bit of freedom for people to choose the outcomes of scenarios. Painters, writers, film makers and news reporters are some of the main people involved in the way reality is interpreted because they are in the spotlight. Every one watches them, reads their papers or interperates their work. It is important for people to recognise that regardless of the message that is trying to be brought across, reality is subjective, and hence, it may appear fictitious to anyone apart from their maker. Commercial or artistic.

Honor :: essays research papers

HONOR CAN BE DEFINED IN SO MANY WAYS CAN mean respect and esteem shown to another. HONOR may ALSO apply to the recognition of one's right to great respect or to any expression of such recognition IN SOME SITUATIONS IT implies profound respect mingled with love, devotion.There is a priceless respect that everyone in the world possesses, and that is the. respect of a person?s honor. A person?s honor is something that can not be bought, sold,. or traded it?s something that must be gained by the respect of your peers. An example of. how honor is seen in everyday life in through a persons word. The standard dictionary definition of honor first lists public regard and esteem under the word, with ethical conduct or high standards of justice and responsibility appearing much further down the list. This is reflected in the way the modern world treats the issue of honor. In ancient times, honor was the manner of being that we now describe as having integrity. In plain language, an honorable p erson avoids deception whenever possible, treats others with respect and sticks to her beliefs no matter how others think or act. People generally do not seem to behave very well toward each other any more.Honor determines the hierarchy of an individual while revealing his loyalty and true intentions. Reward comes for those at the top whose honor does not diminish, while a false or fleeting honor of a lesser mortal causes destruction. Exploring and discussing how to act honorably toward each other is a place to start.The greatest way to live with honor in this world is to be what we pretend to be. How can you be a person of integrity? First, figure out what integrity (honor) is. My mother used to say to treat others the way you wanted to be treated. Does anyone do that these days? Well, I know that I don't want to be cut off in traffic, or yelled at, or bumped into rudely at the grocery store, or left picking up garbage all over my yard from the street. So I could try not to do thos e things to other people. I won't cut off others in traffic, or yell, or act rude at the grocery store, or throw garbage in the street. That's just a place to start. Treat others the way you want to be treated.

An Approach to Detect and Prevent Sql Injection Attacks in Database Using Web Service

IJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. 1, January 2011 197 An Approach to Detect and Prevent SQL Injection Attacks in Database Using Web Service IndraniBalasundaram 1 Dr. E. Ramaraj2 1 Lecturer, Department of Computer Science, Madurai Kamaraj University, Madurai 2 Director of Computer Centre Alagappa University, Karaikudi. Abstract SQL injection is an attack methodology that targets the data residing in a database through the firewall that shields it. The attack takes advantage of poor input validation in code and ebsite administration. SQL Injection Attacks occur when an attacker is able to insert a series of SQL statements in to a ‘query’ by manipulating user input data in to a web-based application, attacker can take advantages of web application programming security flaws and pass unexpected malicious SQL statements through a web application for execution by the backend database. This paper proposes a novel specification-ba sed methodology for the prevention of SQL injection Attacks. The two most important advantages of the new approach against xisting analogous mechanisms are that, first, it prevents all forms of SQL injection attacks; second, Current technique does not allow the user to access database directly in database server. The innovative technique â€Å"Web Service Oriented XPATH Authentication Technique† is to detect and prevent SQLInjection Attacks in database the deployment of this technique is by generating functions of two filtration models that are Active Guard and Service Detector of application scripts additionally allowing seamless integration with currently-deployed systems. General TermsLanguages, Security, Verification, Experimentation. Keywords Database security, world-wide web, web application security, SQL injection attacks, Runtime Monitoring changes to data. The fear of SQL injection attacks has become increasingly frequent and serious. . SQL-Injection Attacks are a cl ass of attacks that many of these systems are highly vulnerable to, and there is no known fool-proof defend against such attacks. Compromise of these web applications represents a serious threat to organizations that have deployed them, and also to users who trust these systems to store confidential data. The Web applications hat are vulnerable to SQL-Injection attacks user inputs the attacker’s embeds commands and gets executed [4]. The attackers directly access the database underlying an application and leak or alter confidential information and execute malicious code [1][2]. In some cases, attackers even use an SQL Injection vulnerability to take control and corrupt the system that hosts the Web application. The increasing number of web applications falling prey to these attacks is alarmingly high [3] Prevention of SQLIA’s is a major challenge. It is difficult to implement and enforce a rigorous defensive coding discipline. Many olutions based on defensive coding ad dress only a subset of the possible attacks. Evaluation of â€Å"â€Å"Web Service Oriented XPATH Authentication Technique† has no code modification as well as automation of detection and prevention of SQL Injection Attacks. Recent U. S. industry regulations such as the Sarbanes-Oxley Act [5] pertaining to information security, try to enforce strict security compliance by application vendors. 1. Introduction 1. 1 SAMPLE – APPLICATION Information is the most important business asset in today’s environment and achieving an appropriate level of Information Security. SQL-Injection Attacks (SQLIA’s) re one of the topmost threats for web application security. For example financial fraud, theft confidential data, deface website, sabotage, espionage and cyber terrorism. The evaluation process of security tools for detection and prevention of SQLIA’s. To implement security guidelines inside or outside the database it is recommended to access the sensitive databases should be monitored. It is a hacking technique in which the attacker adds SQL statements through a web application's input fields or hidden parameters to gain access to resources or make Application that contain SQL Injection vulnerability.The example refers to a fairly simple vulnerability that could be prevented using a straightforward coding fix. This example is simply used for illustrative purposes because it is easy to understand and general enough to illustrate many different types of attacks. The code in the example uses the input parameters LoginID, password to dynamically build an SQL query and submit it to a database. For example, if a user submits loginID and password as â€Å"secret,† and â€Å"123,† the application dynamically builds and submits the query: Manuscript received January 5, 2011 Manuscript revised January 20, 2011 198IJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. 1, January 2011 SELECT * from FROM loginID=’secret’ AND pass1=123 user_info WHERE If the loginID and password match the corresponding entry in the database, it will be redirect to user_main. aspx page other wise it will be redirect to error. aspx page. 1. dim loginId, Password as string 2. loginId = Text1. Text 3. password = Text2. Text 3. cn. open() 4. qry=†select * from user_info where LoginID=’† & loginID & â€Å"’ and pass1=† & password & â€Å"† 5. cmd=new sqlcommand(qry,cn) 6. rd=cmd. executereader() 7. if (rd. Read=True) Then 8. Response. redirect(â€Å"user_main. spx†) 9. else 10. Response. redirect(â€Å"error. aspx†) 11. end if 12. cn. close() 13. cmd. dispose() b. Union Query In union-query attacks, Attackers do this by injecting a statement of the form: UNION SELECT because the attackers completely control the second/injected query they can use that query to retrieve information from a specified table. The result of this attack is that th e database returns a dataset that is the union of the results of the original first query and the results of the injected second query. Example: An attacker could inject the text â€Å"’ UNION SELECT pass1 from user_info where LoginID=’secret – -† nto the login field, which produces the following query: SELECT pass1 FROM user_info WHERE loginID=’’ UNION SELECT pass1 from user_info where LoginID=’secret’ — AND pass1=’’ Assuming that there is no login equal to â€Å"†, the original first query returns the null set, whereas the second query returns data from the â€Å"user_info† table. In this case, the database would return column â€Å"pass1† for account â€Å"secret†. The database takes the results of these two queries, unions them, and returns them to the application. In many applications, the effect of this operation is that the value for â€Å"pass1† is displayed along with the account informationFigure 1: Example of . NET code implementation. 1. 2 Techniques of SQLIA’S Most of the attacks are not in isolated they are used together or sequentially, depending on the specific goals of the attacker. a. Tautologies Tautology-based attack is to inject code in one or more conditional statements so that they always evaluate to true. The most common usages of this technique are to bypass authentication pages and extract data. If the attack is successful when the code either displays all of the returned records or performs some action if at least one record is returned. Example: In this example attack, an attacker submits â€Å" ’ or 1=1 – -†The Query for Login mode is: SELECT * FROM user_info WHERE loginID=’’ or 1=1 – AND pass1=’’ The code injected in the conditional (OR 1=1) transforms the entire WHERE clause into a tautology the query evaluates to true for each row in the table and returns a ll of them. In our example, the returned set evaluates to a not null value, which causes the application to conclude that the user authentication was successful. Therefore, the application would invoke method user_main. aspx and to access the application [6] [7] [8]. c. Stored Procedures SQL Injection Attacks of this type try to execute stored procedures present in the database.Today, most database vendors ship databases with a standard set of stored procedures that extend the functionality of the database and allow for interaction with the operating system. Therefore, once an attacker determines which backend database is in use, SQLIAs can be crafted to execute stored procedures provided by that specific database, including procedures that interact with the operating system. It is a common misconception that using stored procedures to write Web applications renders them invulnerable to SQLIAs. Developers are often surprised to find that their stored procedures can be just as vulner able o attacks as their normal applications [18, 24]. Additionally, because stored procedures are often written in special scripting languages, they can contain other types of vulnerabilities, such as buffer overflows, that allow attackers to run arbitrary code on the server or escalate their privileges. CREATE PROCEDURE DBO. UserValid(@LoginID varchar2, @pass1 varchar2 AS EXEC(â€Å"SELECT * FROM user_info WHERE loginID=’† [email  protected]+ â€Å"’ and pass1=’† [email  protected]+ â€Å"’†);GO Example: This example demonstrates how a parameterized stored procedure can be exploited via an SQLIA. In the example, we assume that the query string constructed at ines 5, 6 and 7 of our example has been replaced by a call IJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. 1, January 2011 to the stored procedure defined in Figure 2. The stored procedure returns a true/false value to indicate whether the u ser’s credentials authenticated correctly. To launch an SQLIA, the attacker simply injects â€Å" ’ ; SHUTDOWN; –† into either the LoginID or pass1 fields. This injection causes the stored procedure to generate the following query: SELECT * FROM user_info WHERE loginID=’secret’ AND pass1=’; SHUTDOWN; -At this point, this attack works like a piggy-back attack.The first query is executed normally, and then the second, malicious query is executed, which results in a database shut down. This example shows that stored procedures can be vulnerable to the same range of attacks as traditional application code [6] [11] [12] [10] [13] [14] [15]. d. Extended stored procedures IIS(Internet Information Services) Reset There are several extended stored procedures that can cause permanent damage to a system[19]. Extended stored procedure can be executed by using login form with an injected command as the LoginId LoginId:';execmaster.. xp_xxx;-Passwo rd:[Anything] LoginId:';execmaster.. p_cmdshell'iisreset';-Password:[Anything] select password from user_info where LoginId=†; exec master.. xp_cmdshell ‘iisreset'; –‘ and Password=† This Attack is used to stop the service of the web server of particular Web application. Stored procedures primarily consist of SQL commands, while XPs can provide entirely new functions via their code. An attacker can take advantage of extended stored procedure by entering a suitable command. This is possible if there is no proper input validation. xp_cmdshell is a built-in extended stored procedure that allows the execution of arbitrary command lines. For example: exec master.. p_cmdshell ‘dir' will obtain a directory listing of the current working directory of the SQL Server process. In this example, the attacker may try entering the following input into a search form can be used for the attack. When the query string is parsed and sent to SQL Server, the server wi ll process the following code: SELECT * FROM user_info WHERE input text =† exec master.. xp_cmdshell LoginId /DELETE'–‘ 199 Here, the first single quote entered by the user closes the string and SQL Server executes the next SQL statements in the batch including a command to delete a LoginId to the user_info table in the database. . Alternate Encodings Alternate encodings do not provide any unique way to attack an application they are simply an enabling technique that allows attackers to evade detection and prevention techniques and exploit vulnerabilities that might not otherwise be exploitable. These evasion techniques are often necessary because a common defensive coding practice is to scan for certain known â€Å"bad characters,† such as single quotes and comment operators. To evade this defense, attackers have employed alternate methods of encoding their attack strings (e. g. , using hexadecimal, ASCII, and Unicode character encoding).Common scanning an d detection techniques do not try to evaluate all specially encoded strings, thus allowing these attacks to go undetected. Contributing to the problem is that different layers in an application have different ways of handling alternate encodings. The application may scan for certain types of escape characters that represent alternate encodings in its language domain. Another layer (e. g. , the database) may use different escape characters or even completely different ways of encoding. For example, a database could use the expression char(120) to represent an alternately-encoded character x†, but char(120) has no special meaning in the application language’s context. An effective code-based defense against alternate encodings is difficult to implement in practice because it requires developers to consider of all of the possible encodings that could affect a given query string as it passes through the different application layers. Therefore, attackers have been very succe ssful in using alternate encodings to conceal their attack strings. Example: Because every type of attack could be represented using an alternate encoding, here we simply provide an example of how esoteric an alternativelyencoded attack could appear.In this attack, the following text is injected into the login field: â€Å"secret’; exec(0x73687574646f776e) – – †. The resulting query generated by the application is: SELECT * FROM user_info WHERE loginID=’secret’; exec(char(0x73687574646f776e)) — AND pass1=’’ This example makes use of the char() function and of ASCII hexadecimal encoding. The char() function takes as a parameter an integer or hexadecimal encoding of a character and returns an instance of that character. The stream of numbers in the second part of the injection is the 200 IJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. , January 2011 ASCII hexadecimal encoding of the strin g â€Å"SHUTDOWN. † Therefore, when the query is interpreted by the database, it would result in the execution, by the database, of the SHUTDOWN command. References: [6] f. Deny Database service This attack used in the websites to issue a denial of service by shutting down the SQL Server. A powerful command recognized by SQL Server is SHUTDOWN WITH NOWAIT [19]. This causes the server to shutdown, immediately stopping the Windows service. After this command has been issued, the service must be manually restarted by the administrator. select password from user_info whereLoginId=';shutdown with nowait; –‘ and Password='0' The ‘–‘ character sequence is the ‘single line comment' sequence in Transact – SQL, and the ‘;' character denotes the end of one query and the beginning of another. If he has used the default sa account, or has acquired the required privileges, SQL server will shut down, and will require a restart in order to f unction again. This attack is used to stop the database service of a particular web application. Select * from user_info where LoginId=’1;xp_cmdshell ‘format c:/q /yes ‘; drop database mydb; –AND pass1 = 0 This command is used to format the C: drive used by the ttacker. 2. Related Work There are existing techniques that can be used to detect and prevent input manipulation vulnerabilities. 2. 1 Web Vulnerability Scanning Web vulnerability scanners crawl and scan for web vulnerabilities by using software agents. These tools perform attacks against web applications, usually in a black-box fashion, and detect vulnerabilities by observing the applications’ response to the attacks [18]. However, without exact knowledge about the internal structure of applications, a black-box approach might not have enough test cases to reveal existing vulnerabilities and also have alse positives. 2. 2 Intrusion Detection System (IDS) Valeur and colleagues [17] propose the use of an Intrusion Detection System (IDS) to detect SQLIA. Their IDS system is based on a machine learning technique that is trained using a set of typical application queries. The technique builds models of the typical queries and then monitors the application at runtime to identify queries that do not match the model in that it builds expected query models and then checks dynamically-generated queries for compliance with the model. Their technique, however, like most techniques based on learning, can generate large umber of false positive in the absence of an optimal training set. Su and Wassermann [8] propose a solution to prevent SQLIAs by analyzing the parse tree of the statement, generating custom validation code, and wrapping the vulnerable statement in the validation code. They conducted a study using five real world web applications and applied their SQLCHECK wrapper to each application. They found that their wrapper stopped all of the SQLIAs in their attack set without g enerating any false positives. While their wrapper was effective in preventing SQLIAs with modern attack structures, we hope to shift the focus rom the structure of the attacks and onto removing the SQLIVs. 2. 3 Combined Static and Dynamic Analysis. AMNESIA is a model-based technique that combines static analysis and runtime monitoring [1][7]. In its static phase, AMNESIA uses static analysis to build models of the different types of queries an application can legally generate at each point of access to the database. In its dynamic phase, AMNESIA intercepts all queries before they are sent to the database and checks each query against the statically built models. Queries that violate the model are identified as SQLIA’s and prevented from executing on the database.In their evaluation, the authors have shown that this technique performs well against SQLIA’s. The primary limitation of this technique is that its success is dependent on the accuracy of its static analysis f or building query models. Certain types of code obfuscation or query development techniques could make this step less precise and result in both false positives and false negatives Livshits and Lam [16] use static analysis techniques to detect vulnerabilities in software. The basic approach is to use information flow techniques to detect when tainted input has been used to construct an SQL query. These ueries are then flagged as SQLIA vulnerabilities. The authors demonstrate the viability of their technique by using this approach to find security vulnerabilities in a benchmark suite. The primary limitation of this approach is that it can detect only known patterns of SQLIA’s and, IJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. 1, January 2011 because it uses a conservative analysis and has limited support for untainting operations, can generate a relatively high amount of false positives. Wassermann and Su propose an approach that uses stati c analysis combined with automated reasoning to verify that he SQL queries generated in the application layer cannot contain a tautology [9]. The primary drawback of this technique is that its scope is limited to detecting and preventing tautologies and cannot detect other types of attacks. 3. Proposed Technique This Technique is used to detect and prevent SQLIA’s with runtime monitoring. The solution insights behind the technique are that for each application, when the login page is redirected to our checking page, it was to detect and prevent SQL Injection attacks without stopping legitimate accesses. Moreover, this technique proved to be efficient, imposing only a low overhead on the Web pplications. The contribution of this work is as follows: A new automated technique for preventing SQLIA’s where no code modification required, Webservice which has the functions of db_2_XMLGenrerator and XPATH_ Validator such that it is an XML query language to select specific part s of an XML document. XPATH is simply the ability to traverse nodes from XML and obtain information. It is used for the temporary storage of sensitive data’s from the database, Active Guard model is used to detect and prevent SQL Injection attacks. Service Detector model allow the Authenticated or legitimate user to access the web applications.The SQLIA’s are captured by altered logical flow of the application. Innovative technique (figure:1) monitors dynamically generated queries with Active Guard model and Service Detector model at runtime and check them for compliance. If the Data Comparison violates the model then it represents potential SQLIA’s and prevented from executing on the database. This proposed technique consists of two filtration models to prevent SQLIA’S. 1) Active Guard filtration model 2) Service Detector filtration model. The steps are summarized and then describe them in more detail in following sections. a. Active Guard Filtration Mod elActive Guard Filtration Model in application layer build a Susceptibility detector to detect and prevent the Susceptibility characters or Meta characters to prevent the malicious attacks from accessing the data’s from database. b. Service Detector Filtration Model Service Detector Filtration Model in application layer validates user input from XPATH_Validator where the Sensitive data’s are stored from the Database at second 201 level filtration model.

Identify hotspot This step performs a simple scanning of the application code to identify hotspots. Each hotspot will be verified with the Active Server to remove the susceptibility character the sample code (figure: 2) states two hotspots with a single query execution. (In . NET based applications, interactions with the database occur through calls to specific methods in the System. Data. Sqlclient namespace, 1 such as Sqlcommand- . ExecuteReader (String)) the hotspot is instrumented with monitor code, which matches dynamically generated queries against query models. If a generated query is matched with Active Guard, then it is onsidered an attack. 3. 1 Comparison of Data at Runtime Monitoring When a Web application fails to properly sanitize the parameters, which are passed to, dynamically created SQL statements (even when using parameterization techniques) it is possible for an attacker to alter the construction of back-end SQL statements. IJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. 1, January 2011 When an attacker is able to modify an SQL statement, the statement will execute with t he same rights as the application user; when using the SQL server to execute commands that interact with the operating system, the rocess will run with the same permissions as the component that executed the command (e. g. , database server, application server, or Web server), which is often highly privileged. Current technique (Figure: 1) append with Active Guard, to validate the user input fields to detect the Meta character and prevent the malicious attacker. Transact-SQL statements will be prohibited directly from user input. For each hotspot, statically build a Susceptibility detector in Active Guard to check any malicious strings or characters append SQL tokens (SQL keywords and operators), delimiters, or string tokens to the legitimate command.Concurrently in Web service the DB_2_Xml Generator generates a XML document from database and stored in X_PATH Validator. Service Detector receive the validated user input from Active Guard and send through the protocol SOAP (Simple Obj ect Access Protocol) to the web service from the web service the user input data compare with XML_Validator if it is identical the XML_Validator send a flag as a iterator count value = 1 to Service Detector through the SOAP protocol then the legitimate/valid user is Authenticated to access the web application, If the data mismatches the XML_Validator send a flag as a count alue = 0 to Service Detector through the SOAP protocol then the illegitimate/invalid user is not Authenticated to access the web application. In figure 3: In the existing technique query validation occur to validate a Authenticated user and the user directly access the database but in the current technique, there is no query validation . From the Active Guard the validated user input fields compare with the Service Detector where the Sensitive data is stored, db_2_XML Generator is used to generate a XML file and initialize to the class XPATH document the instance Navigator is used to search by using cursor in the selected XML document.With in the XPATH validator, Compile is a method which is used to match the element with the existing document. The navigator will be created in the xpathdocument using select method result will be redirected to the XPATH node iterator. The node iterator count value may be 1 or 0, If the flag value result in Service Detector as 1 then the user consider as Legitimate user and allowed to access the web application as the same the flag value result in Service Detector as 0 then the user consider as Malicious user and reject/discard from accessing the web application If the script builds an SQL query by concatenating hard-coded trings together with a string entered by the user, As long as injected SQL code is syntactically correct, tampering cannot be detected programmatically. String concatenation is the primary point of entry for script injection Therefore, 203 we Compare all user input carefully with Service Detector (Second filtration model). If the user input and Sensitive data’s are identical then executes constructed SQL commands in the Application server. Existing techniques directly allows accessing the database in database server after the Query validation. Web Service Oriented XPATH Authentication Technique does not allow directly to ccess database in database server. 4.

Table 1 shows that the proposed technique prevented all types of SQLIA s in all cases. The proposed technique is thus a secure and robust solution to defend against SQLIA’sIJCSNS International Journal of Computer Science and Network Security, VOL. 11 No. 1, January 2011 204 4. 2 Execution Time at Runtime Validation The runtime validation incurs some overhead in terms of execution time at both the Web Service Oriented XPATH Authentication Technique and SQL-Query based Validation Technique. Taken a sample website ETransaction measured the extra computation time at the query validation, th is delay has been amplified in the graph (figure: 4 and figure:5) to distinguish between the Time delays using bar chart shows that the data validation in XML_Validator performs better than query validation.In Query validation(figure:5) the user input is generated as a query in script engine then it gets parsed in to separate tokens then the user input is compared with the statistical generated data if it is malicious generates error reporting. Web Service Oriented XPATH Authentication Technique (figure: 4) states that user input is generated as a query in script engine then it gets parsed in to separate tokens, and send through the protocol SOAP to Susceptibility Detector, then the validated user data is sequentially send to Service Detector through the protocol SOAP then the user input is ompared with the sensitive data, which is temporarily stored in dataset. If it is malicious data, it will be prevented otherwise the legitimate data is allowed to access the Web application. 5. C ONCLUSION SQL Injection Attacks attempts to modify the parameters of a Web-based application in order to alter the SQL statements that are parsed to retrieve data from the database. Any procedure that constructs SQL statements could potentially be vulnerable, as the diverse nature of SQL and the methods available for constructing it provide a wealth of coding options. 1800000 Execution time in Milli Sec 1600000 1400000 1200000 000000 Proposed Technique Existing Technique 800000 600000 400000 200000 0 1000 2000 3000 4000 5000 6000 Total Number of Entries in Database Figure4: Execution Time comparison for proposed technique (data validation in X-path) with existing technique The primary form of SQL injection consists of direct insertion of code into parameters that are concatenated with SQL commands and executed. This technique is used to detect and prevent the SQLI flaw (Susceptibility characters & exploiting SQL commands) in Susceptibility Detector and prevent the Susceptibility att acker Web Service Oriented XPATH Authentication Technique hecks the user input with valid database which is stored separately in XPATH and do not affect database directly then the validated user input field is allowed to access the web application as well as used to improve the performance of the server side validation This proposed technique was able to suitably classify the attacks that performed on the applications without blocking legitimate accesses to the database (i. e. , the technique produced neither false positives nor false negatives).

Argumentative Essay First Amendment Junkie By Susan...

Amber Rogers Dr. Kim Loel Argumentative Analysis of the Essay â€Å"First Amendment Junkie† by Susan Jacoby What is a First Amendment Junkie? According to author Susan Jacoby, censorship of any form is wrong. From the beginning of Jacoby’s essay, â€Å"First Amendment Junkie,† it’s obvious where she stands on the topic. Jacoby states that the people who most support the censorship of pornography are women. These women are often self-proclaimed feminists who ironically support the First Amendment. While criticizing the production of pornography, these feminists attempt to argue that â€Å"mainstream† pornography is no different than child porn. However, they fail to realize the obvious error in this argument because this is simply not a first†¦show more content†¦If pornography is censored because it offends certain people, then what about religion, or even sexual orientation? Sure, gay marriage has recently been legalized, but there are some people in this country who find it just as offensive and obscene as some people find pornography. Are we as a country supposed to satisfy the sensibilities of one group of people (i.e.: self-proclaimed feminists, in this case) simply because something bothers them or are we right to allow the freedom of expression that pornography claims to be to keep in ordinance with the First Amendment? And what about fictional characters such as Santa Claus and the Easter Bunny which is offensive to the Christian community? Or those who protest being forced to say the Pledge of Allegiance in schools? Are these people considered less patriotic and should they too be stripped of their First Amendment rights? It’s impossible to censor all disagreeable sides because all that would be left is a bland â€Å"politically correct† society and that’s an unattainable goal because it’s not possible to please everyone. In the end, there will always be someone who disagrees with someone else about something and they will indeed use their First Amendment right to free speech to voice these grievances. As per her written essay, Jacoby is â€Å"First Amendment junkie,†
