Intrusion detection systems Essay Example | Topics and Well Written Essays - 2000 words

Intrusion detection systems - Essay Example IDS is the short form for the Intrusion Detection Systems. These systems basically find out the manner in which unwanted signals towards the systems are manipulated. In fact there are a host of different kinds that come under the IDS heading. Moreover, coming to the point of these manipulations which occur in the first place, we discern that these are the usual attacks that are carried out by the hackers who are skilled and quite adept at their work and even at times, script kiddies do play these tricks whereby they make use of the automated scripts to achieve their objectives. IDS thus looks at the malicious data traffic that is taking place in computer networks as well as tries its best at finding out the spots where the firewall would not play its active part and thus seize the chance of finding the loopholes that might exist within a computer and indeed the whole of the network under question. Thus what is left unattended and undiscovered by the computer firewall is usually caugh t by the IDS which makes its functions look all the more imperative in the related scheme of computer networking and security issues that arise every now and then.Thus vulnerable services are saved from the attacks and applications are saved as a result of the precaution which has been applied.The components which make up the IDS include the sensors, a console and a central engine. They are briefly highlighted here. Sensors play their active part in the generation of events related with security issues.

Clean Fuels and Dirty Fuels Essay Example | Topics and Well Written Essays - 1750 words

Clean Fuels and Dirty Fuels - Essay Example (US Sec 963) Emission Benefits: Clean fuels have numerous properties which make them cleaner than other dirty fuels like gasoline or adulterated diesel mixtures. Usually these fuels release fewer hydrocarbons, and the hydrocarbons emitted are less toxic and less reactive. Emissions from electricity, natural gas, or alcohol-powered vehicles can be roughly about 90% lesser than in toxics and ozone-forming hydrocarbons than emissions from vehicles using dirty fuel. (Chemical Engineering Tools and Information) Mileage Benefits: Apart from the emission benefits, the best thing that appeals the minds of the users is that the mileage difference is notable, which results in a lot of cost saving. Here, it is to be noted that there is a win-win situation. The better mileage advantage helps the companies increase their sale. Moreover, the customers get more than just cost effectiveness. European and Japanese automakers are about to invade the market with new clean-diesel models that catch much better mileage than the standard gasoline-burning model. Among the many contenders, Mercedes shall offer its SUVs -- M-Class, R-Class and GL-Class --with diesel engines. BMW aims to bring its popular turbo diesel engines to US models. And Nissan is coming with a diesel Maxima sedan. Volkswagen was an early pioneer in diesel in the US, but it will convert to new cleaner diesel technology in models starting 2008, which it dubs "Blue Motion." VW is betting its new TDI Jetta, which launches in February, will h elp stoke its US sales. (Business week May 04 2007) This makes it clear that the model is not only gaining popularity for its air benefits but also finding high acceptance with the users, which is why the major players have shifted their focus to it. The concept of clean fuels actually came up to start with its clean atmosphere benefits, but eventually in the drive vehicle manufacturers opened their eyes to its selling points too. Today, they have been able to design innovative models resulting in cost effectiveness, speed, lower maintenance etc. for the users compared to the conventional petrol and diesel run trucks/cars. It is to be noted that The 2007 Mercedes-Benz E320 BLUETEC is the first model in America to take advantage of the clean low-sulfer diesel (Autos, MSN) Feasibility Clean fueled transport vessels are in use and widespread usage in the near future is feasible. To facilitate the changeover, technologies must be polished so that the vehicles can be made to attain optimal performance and emissions features. Users must show their acceptability to better and newer vehicles and fuels, and industry as well as government must cooperate to ensure their availability. It would take a concerted endeavor by all segment s of the society, but a shift to clean fuels can be the most feasible way for cities to have clean air and for users to have a better performance along with cost cutting. Dirty Fuels Meaning Fuel that is contaminated with water, particles, etc., generally causing an engine to

Company needs to analyze the general environment

Company needs to analyze the general environment A large company needs to analyze the general environment when making global strategy and doing international business. Included by the general environment, the terms of demographic, economic, political/legal, sociocultural, technological and global have different impacts on the strategy of a company. Demographic In the term of demographic, it can be divided into two factors, gender and age, which are important to the market of Nike, because Nike, a large multinational company, has stores in almost all regions over the world, and the strategy making can be focused on these two factors. Focused on the gender, the market of female is great and the need of sportswear for women is high. Firstly, the women sports players are getting more and more professional and begin to stand on the stage of the world high level games such as Olympic Games and grand slam in tennis, which makes female sports players and their fans have a need of sportswear. Secondly, with the development of the society of most countries, women are getting aware the importance of their rights (Foster, 2001), which helps them have a thought of taking sports like males. Also, in the term of age, Nike has a market of middle aged people in some countries especially in China, and it can provide casual sportswear to meet the target customers needs. First of all, though Nike used Jordan to make advertisement several years ago and changed the person who cooperates with the company, the fans of the heroes will not change and still have a need of Nike sportswear (Jung, 2005). Also, after entering the Chinese market in 1995, the revenue of Nike is stably growing and gains a group of people who have high loyalty of the Nike brand (Jung, 2005), and the age of these loyal customers is getting higher, which may become a huge needs of sportswear suitable for middle aged people. Through demographic, the females and middle aged people may have a huge need of Nike sportswear and will become a large market. And, when Nike is meeting the youngsters needs of profession, the middle aged customers may have more needs of fitness rather than competition. So Nike can design some new series of sportswear to meet their needs. Political/legal To save the cost is essential for a large company like Nike; Asian sourcing has allowed low manufacturing costs relative to the quality of the products. Thus, Asian sourcing has always been nearly as central to Nike strategy as using famous athletes to attest to the virtues of Nike equipment in athletic performances (Kahle, Boush and Phelps, 2000, p43). However, Nike is blamed for using low labor in low cost lacking of humanity. Nike seems to pay salaries lower than the standard given by the Indian government (Jung, 2005). This problem will leave really negative influences on Nike. Also, outsourcing production to factories in Vietnam and labors are used without human rights, such as working overtime and being neglected the health situation, brings out conflicts between the company and the society. Nike may lose its reputation among customers, and the brand of Nike may become not as cool as it should be. When the challenge started coming about labor conditions in Vietnam and Southeast Asia and other parts of the world, everyone heard about Nike workers without, of course, making the distinction that they were contract workers. When all of this was going on, about a third of the senior managers were in tears during the meeting. They were embarrassed- with their neighbors, their families, and their friends- by being Nike employees. Said Schwartz (2000, p8) The legality of labor using should be concerned by Nike even it just outsource the production to other factories, because the legality may affect Nikes reputation a lot. And both the revenue and the royalty of customers will be affected by the changes of reputation. So, the legality is what manufacturing companies like Nike has to concern about, because society confirms a businesss legitimacy, and failure to consider societal impact can destroy a reputation. (Schwartz, 2000, p7) Economic The economic situation for a country should be concerned by companies doing international business like Nike, because peoples budget that affects the marketing potential is influenced by the economy and financial policy of the country. Since the needs of the market will depend on the budget and economic behavior of people (Boje, 2001), companies should think about the economic term. With the broken out of subprime crisis, the economy of US is going worse, and a large number of countries, such as Iceland, have been negatively influenced, which will lead to a retrench of budget and the market. Also, in countries who are sensitive to finance such as US, UK and Swiss, people are going with the budget strictly (Francesco and Gold, 2001, p27), and with the downward economic situation, the market may get smaller. However, the markets in the regions not affected greatly such as Asia and Middle Eastern is more stable relatively. Under this kind of situation, the needs of products and the market should become lower and smaller. Also, with the growth of the cost, it may lead to a reduction of revenue in the whole and restrict the development of Nike in the worldwide market though Nike may have the capability to keep the market share and still win the competition among Adidas, Puma and Nike. Sociocultural As a sportswear company, Nike needs to know what the socioculture, a persons understanding of sports, should be in a region or a field of sports events. First of all, it is found that people are always showing the respect to heroes, especially the sports heroes in real life (Jung, 2005), so companies including Nike uses excellent sports players like Jordan to make film and advertisements for it in order to develop peoples adoration to the heroes so that the needs will be created. Also, because of the culture of success adoration, the needs may get enhanced if fans of the heroes feel that Nike can make positive effects on them. And Nike got additional market value when Tiger is in contention to win and a positive impact on his performance because of Nikes products is believed by the society (Farrell, Karels and McClatchey, 2000, p3). However, people in different areas have different sociocultures on sport events, such as soccer for Europe and basketball for US, so when making strategi es, Nike can try to identify the different needs in the target markets. So, to understand the socioculture of a region can help companies like Nike define its target market and find an appropriate way to make marketing and promotion. Also, according to the sports culture of an area and the needs of target market, to communicate with local players and design a product with them might be helpful in terms of both market and technology. Technological Customers nowadays have higher requirements on the technology of the products. Firstly, people are more captious than before. The technology of Nike Air gets blamed because people find that the air cannot support feet enough and may lead to injury(CBC News, 2006). Also, people need Nikes products be made with the technology of not only fitness and safety but also fashionable and cool one such as IT technology. Nike is working with Apple and produce Nike+ with a sensor connecting iPod in order to meet peoples needs. The needs of hi-tech make companies like Nike and IT companies like Apple come together, working out a strategy and making innovation in order to enhance the strength of them and achieve the markets needs. Global With the pace of globalization, areas in different parts of the world get connection and MNCs are setting more and more stores in different regions. Though Nike has great quantity of store all over the world, it can control all the stores at the same time (Hansen and Nohria, 2006, p12). However, though countries go closer because of the globalization, special needs in different cultures are still exist, which makes Nikes products have some differences when selling in different regions. This situation leaves Nikes products a diversification even in one series. But too diversified products will lead to a mass in the market and make customers feel confusing (Hemp, 2006, p50). Nike should make some differences in its products in order to meet different needs, but the standardization of products should also be focused. So, to make the balance between centralization and diversification of the products is what Nike should concern about in the global market. Industrial Environment In the term of industrial environment, the five forces model created by Michael Porter will be used to analyze Nike. Rivalry among competing firms Since Nike is an international company that has their product selling worldwide, it has countless of competitors, including many domestic local firms. However, only a few international companies are Nikes major competitors, such as Adidas, Reebok and Puma. Also, merger makes the athletics industry more concentrated. Nike bought Converse in 2003 and Adidas bought Reebok in August 2005, and half of the worldwide market is shared by these two top players (Jung, 2005). And, the notable companies such as Adidas, New Balance have different values and markets. Nike has a main market for US basketball while Adidass is European soccer and fashion and casual sports for New Balance, which makes them have different markets and target customers. However, to enter a new market like soccer is not easy for Nike even it made great efforts. Nike worked with Google to create joga.com, an Orkut-like site for soccer fans (Christopher, 2008, p6) in order to develop the soccer market which is defined as on e of the most important in terms of growth rate (Pagliano, 2004). So the rivalry among competing firms is low because there are few companies with strong competing power, but the competition among large companies is great. And, if Nike wants to develop the soccer market in Europe, the great investment on advertising and a method of changing the classic and traditional culture of Europeans should be concerned. Threat of new entrants Top players, such as Nike, Adidas and Puma, in the footwear industry made a high entry barrier to reduce the threat of new comers. First of all, these companies put a great investment on advertisement and marketing. Nike had 50 sponsored Athletes win a gold medal in Athens 2004. Adidas spent $80 million for the Official Sportswear partner title in Beijing 2008. And the high investment makes new firms hard to compete with them, even enter the market because sales for companies in this industry mainly depend on the marketing performance (Christopher, 2008, p6). Innovation is another way to keep a lead on would be competitors. Companies are making efforts to develop their technology and create new functions such as Nike+, the sensor connecting with iPod, which can not only gain more customers but also keep new firms with low technology out of the worldwide market. However, though Nike and Adidas are leading the market, a local company, Li-Ning, came to the worldwide market. Li-Ning sponsors 4 Chinese teams for the Olympics, and its products are about half as expensive as those of its foreign rivals, and its network of stores dwarfs that of any other player (Terjesen, 2007), which might be the advantage for Li-Ning. So, local companies may succeed to enter the local market and use its low price as advantage to compete with leaders though the entering barrier is high. Nike should focus on the new comers with both the development of technology and lower price who might become a strong threat to top players in the future when making strategies, even though these local companies cannot compete with Nike today. Threats of substitutes Since athletic shoes and sportswear are designed to improve comfort and personal safety during sports, the substitutes for athletic footwear products are low because there are little alternatives to switch. Though people except athletes are still likely to use boots or sandals to substitute sportswear, doing sports is an essential and basic factor in peoples life and the need of sportswear is exist for everyone. Therefore, there are no real substitutes for athletic footwear and sportswear. Bargaining power of supplier In order to reduce the cost, Nike make outsourcing of their process of production to low labor cost countries, mainly China and Vietnam. Nikes products are manufactured in more than 700 factories and more than 500,000 workers in 51 countries, but only over 20000 direct employees for Nike working in US (Locke, 2006, p6). Suppliers have very low power since they are competing worldwide with thousands of other suppliers. Also, firms like Nike are able to switch between suppliers quickly and cheaply, so these suppliers become dependent on these firms for survival. And, the competition among factories is really high even problems such as low wages in Indonesia, child labor in Pakistan and health and safety problems in Vietnam occurred (Locke, 2006, pp.13-16) because of the low bargaining power of supplier. Bargaining power of buyer The threat of bargaining power of buyer is low because customers do not have a lot of choices when they are choosing athletic wears. First of all, unlike other products, footwear has its own function such as an improvement of safety. Customers, especially athletes, have a need of the technology of the shoes which is the strength of large companies such as Adidas, Nike even Li-Ning. Also, the fans of sports players will use what the players use, which helps companies like Nike and Adidas build a loyalty of customers. The sales of Nike Golf products grew a lot when Tiger Woods showed an improvement in his performance (Farrell, Karels and McClatchey, 2000, p3) because customers also want to improve their performance by using Nikes products. However, though the bargaining power of buyer is low in the industry, some people are buying products of Nike because of the apotheosis of their sports heroes, which shows that a lot of customers may have a loyalty to other brand like Adidas and Li-Ning. So to attract people without brand loyalty is much easier and more important than concentrating on those with a high loyalty to their heroes. Conclusion The analysis of general environment and industrial environment can be concluded that Nike nowadays is under low threats in the industry with some problems still existing. Also, as a leading company of sportswear industry, Nike should not only focus on the development of technology and working with companies in other industries, but also keep the high quality of marketing and promotion. And, the factories Nike does outsourcing business with should be executed by direct employees from Nike because the neglecting of the problems happened in these factories will result in a loss of reputation. With the pace of globalization, there are both threats and opportunities for Nike. And to concern the environment of the industry and the world market will help Nike make strategies and develop more easily and scientifically.

Dostoevsky as Performer Essay -- Russian Literature Christianity Relig

Dostoevsky as Performer Storytelling and reading aloud played a valuable part in young Fyodor's life, influencing his own later successful writing endeavors as well as his performance of literature. His nanny and wet nurse introduced the Dostoevsky children to folklore and lives of the saints through the stories they told. Nanny Alyona Frolovna "told the children stories of ancient Russia, of Saint Sergey of Moscow subduing a bear by the power of his holiness, of heroes and legends and folk tales, Christianity and Russian myth intertwined"; the stories were so vivid and frightening that the children had trouble sleeping (Gunn 10). During the winter their former wet nurses would make a ceremonial visit to the Dostoevsky family, staying two or three days and spending the afternoons telling stories. Such is the power of the spoken word that these women, according to Leonid Grossman, "awakened the boy's interest in the oral poetry of his people and at the same time fostered the development of that beautiful lan guage--freeflowing, emotionally charged, profoundly Russian and memorably expressive--in which, in time, his worldfamous books would be written" (10). Joseph Frank attributes these storytellers' tales of the saints with feeding "Dostoevsky's unshakable conviction that the soul of the Russian peasant was imbued with the Christian ethos of love and selfsacrifice" (1976, 49). The Dostoevsky children were also entertained and educated with oral readings by their parents, especially during the long evenings of the Russian winter. As the family gathered in the parlor, the physician father would read aloud before dinner when he was not occupied with his patients, and the children often went to sleep with the sound of one of th... ...Indianapolis and New York: BobbsMerrill, 1975.

A Composition of My Mother Essay

I am a country girl, and my mother is a country woman. She and my father are both junior-middle school graduates. Partly because of this, I, as their only daughter, bear their high expectations of me becoming a university graduate. Besides, I think their big hopes on me also come from some historical reasons our neighbor, my grandpa’s younger brother’s family, have been mean to us. The second family in our neighborhood to build a two-story brick house, they are far better off than us, and most importantly, they have a university-graduated son so, that’s why I must try to bring credit for my family and make them regret having despised us. Where there is high expectation, there is strictness. I have been obedient since in elementary school. At home, I was obedient to my parents and at school to my teacher. At first, I did well in both Chinese and math, among which my Chinese was better, and this was where the tragedy lay. Besides the homework given by my teachers, there was a great amount of math exercise having asterisk, namely difficult and not required, given by my mother, which she picked from my coach book. Apart from this, I had to practice handwriting for 2 pages on schooldays and 5 on holidays under my mother’s supervision. All those composed my miserable childhood no playing, no joy, only homework, homework and homework. However, my mother’s efforts didn’t work on me, on the contrary, my math was getting worse and my handwriting was neither neat nor beautiful, because every time I just try hard to finish all the endless homework as quickly as I could, pursuing speed but not quality, so that I could have some poor little time to watch cartoons. At that time, I had a strong adoration for music, especially for singing. Both my music teacher and my head teacher in elementary school thought that I had gift in singing, and whenever there were occasions needing performance like Children’s Day, National Day etc. and singing contexts at school or in the community, they offered me the chance to show my talent. And I often lived up to their expectations, winning many prizes in singing. That has been a most glorious period in my school life. Whereas, good times don’t last long. My mother considered my singing a waste of my precious learning time, so she ordered me not to take part in those meaningless things and concentrate on my study. I obeyed and quitted. Now, I am scared of gong KTV and being asked to sing, because after so many years, my talent has abandoned me. For those aforementioned aspects, I hated my mother, because she stripped me of my childhood joy and my singing talent. Although I hated her for those things, I know she loves me and I also love her. The economic condition of my family is bad, as both my parents are peasants and my grandparents were in bad health condition. Diligent and thrifty, my mother is the one in my family to make budget. Even though we lead a hard life, as for expenses on my schooling, such as buying learning materials, coach books, my mother never hesitates for a second to give me the money. Besides, as long as I am studying, even if reading a novel, in no case would my mother ever ask me to do any housework or work in the fields. I know, though she never said, that’s because she, believing deeply that knowledge can change one’s destiny, wanted me to acquire as much as knowledge so as to live a happy and easy life in future, rather than repeat her life, all year round working hard in the field while getting little in return. Though she resorted to some inappropriate ways in educating me, it was out of good intention and out of love. In a word, mother’s love is like the sun’s warmth, while daughter is just like grass, such unselfish and devoted kindness, how can grass repay?

Because I was first Adam

Adam was the first human being to inhabit the earth; he had total authority over every living creature and was free to roam about The Garden of Eden as he pleased. As the story unfolds Eve is created as Adam’s counterpart and they are to live together as one. Many Christians believe that Eve was created inferior to Adam; therefore, man has the authority to rule the relationship. This is not the case – the following will show nature’s natural act of compensation. Men are habitual and as a woman having analyzed the opposite sex I’ve found at they are quite predictable.Men and the television – even though this topic is cliche, it’s always a great place to start. I’ve never known a man that didn’t like The Three Stooges. Curly, Mo and Larry – all three have their quirky habits. Within seconds, the man’s attention is drawn to the television and it stays until the movie’s end. To analyze – the storylines ar e simple, take little concentration and there’s no real point to the story. Women are drawn to the complicated stories with emotional and dramatic story lines – often called â€Å"chick flicks.† We are hoping for the happy ending because we understand how necessary it is to think positive and have an open mind. Thousands of years ago the world was far from discovered and what lied ahead for Adam and Eve was complicated, dramatic and required a positive outlook. Eve’s natural instinct to consider the details and the implications was necessary for the discovery of the world as we know it. Another commonality between males is the love for driving, of course if he takes a wrong turn or loses his way he will not admit it.In the male brain, it’s a sign of weakness to admit failure – it’s far more masculine to drive for hours making that dominant attempt to reach his destination. A woman takes the logical approach; she pulls into the nearest gas station and asks for directions. Looking back thousands of years, again the world was young and there were many miles to discover. Eve’s logical approach to the world was needed. Thousands of years later, we’re still discovering the world. Can you imagine where we would be if we didn’t have the female brain to stop and ask for directions?Men are dominant, they’re instinct is to challenge and conquer. Driving hundreds of miles in one stretch, Football and boxing attract a man’s attention because of that instinct. The female was created to look at the world through a different perspective. We look at the details, consider the implications of our actions and consider the emotional context of certain situations. Neither Adam or Eve were superior to the other, their thought processes were simply different. The male and female complete each other, which explain the necessity of two genders.
