SECURITY :: essays research papers

A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources its own users have access to. Basically, a firewall, working closely with a router program, examines each network packet to determine whether to forward it toward its destination. A firewall also includes or works with a proxy server that makes network requests on behalf of workstation users. A firewall is often installed in a specially designated computer separate from the rest of the network so that no incoming request can get directly at private network resources. There are a number of firewall screening methods. A simple one is to screen requests to make sure they come from acceptable (previously identified) domain name and Internet Protocol addresses. For mobile users, firewalls allow remote access in to the private network by the use of secure logon procedures and authentication certificates. A number of companies make firewall products. Features include logging and reporting, automatic alarms at given thresholds of attack, and a graphical user interface for controlling the firewall. Encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people. Decryption is the process of converting encrypted data back into its original form, so it can be understood. The use of encryption/decryption is as old as the art of communication. In wartime, a cipher, often incorrectly called a "code," can be employed to keep the enemy from obtaining the contents of transmissions. (Technically, a code is a means of representing a signal without the intent of keeping it secret; examples are Morse code and ASCII.) Simple ciphers include the substitution of letters for numbers, the rotation of letters in the alphabet, and the "scrambling" of voice signals by inverting the sideband frequencies. More complex ciphers work according to sophisticated computer algorithms that rearrange the data bits in digital signals. In order to easily recover the contents of an encrypted signal, the correct decryption key is required. The key is an algorithm that "undoes" the work of the encryption algorithm. Alternatively, a computer can be used in an attempt to "break" the cipher.

Beyond Poverty and Misfortune    Ever since I was a young kid I have always been interested with aircraft. I was so curious of how airplane's fly. I remember taking my toys apart to see how it works. As a kid I wanted to go to the airport to watch the airplanes land and fly and pondered how this happens. Other kids wanted to go to the amusement places. As I grew older I became more and more interested in aircraft and the technology behind it. I always involved myself with aviation early on. I read books and magazines on aviation, took museum tours, built model airplanes. When I was younger my father would take me to aircraft repair facilities where I would watch in great fascination. In my teens, went up to the military bases and befriended many soldiers involved with aircraft and asked them numerous questions. I got to meet many aeronautics engineers and borrowed their old textbooks and read them till the wee hours of the morning. As technology improved with information superhighway, I logged on the web. Stayed up for hours and hours searching through web pages and web pages of information about aircraft and technology.    I started my elementary school in the Philippines, then we moved to U.S. and continued my high school education and graduated. Enrolled at the CCSF to pursue my college education and now I am in the 2nd year in CCSF taking aeronautics. My goal now is to obtain my AS degree from the City College of San Francisco (CCSF) so I can transfer to a University and get a Bachelors degree and to continue for my Masters degree in Aeronautics Engineering. I will strive hard to reach the peak level of my career which is a Professor and hopefully to be an aeronautic professor so can help and share my knowledge and experience to the new students who wish to be an aeronautics engineer someday. I completed 62 units from CCSF so far. Currently, I'm taking 21 units. With my hard work in doing my homework and submitted on time; studied hard and gained higher grades on my tests; and did extra credits, I was able to earned a GPA 4.0 last semester `and I was included on the current dean's list in aeronautic s. I received an achievement award for this presented in the Chancellor's Award Ceremony last December 1998 in CCSF.

Look at George and Lennie’s dream Essay

Look at George and Lennie’s dream. Do you think that the dream had any chance of coming true? What made it likely that the dream would fail? From the very beginning ‘Of Mice and Men’, George and Lennie have their hopes set on ‘the dream’. They dream about getting a ranch together in the country. Lennie gets extremely fascinated and excited, as soon as animals are mentioned. He has learnt his trigger speech, word-for-word. He talks about all of the animals he will care for, and how he will feed them: â€Å"†¦a place for alfalfa, an’ that alfalfa is for the rabbits, an’ I take the sack and get it all fulla alfalfa and then I take it to the rabbits†. Lennie is so enthralled, and has thought and talked about the dream so much, that his speech was perfect, and was automatic as soon as he heard any mention of a dream or the animals, especially rabbits. The dream would likely fail, as the story received the title from an earlier poem by Robert Burns, â€Å"The Best Laid Plans Of Mice and Men†. This title portrays the idea, that no matter how planned an idea or a dream is, the outcome, sometimes tragic or not what we expect, has already been decided. John Steinbeck wrote the story in 1937. The story is centred in a place called Salinas. We know this, since the Salinas River is mentioned in the first line of the story. George Milton, described as a â€Å"smart little guy† by Slim, later demonstrates that intelligence without other values is worth nothing. Steinbeck made George in this way, to portray the idea that in almost all walks of life, there will always be natural leaders, and that people emerging with authority, will be an imminent action. Lennie is described as †jes’ like a kid†. Lennie may be child-minded, but is clearly observed as being â€Å"so strong†. He is simple-minded, and is unable to control his own body and strength. This explains why he is unable to understand why the animals he possesses, all die. His strength overpowers their fragility. There is a perfect description of the two men: â€Å"Both men were dressed in denim trousers, and in denim coats with brass buttons. Both wore black, shapeless hats and both carried tight blanket rolls slung over their shoulders†. George and Lennie are identically dressed. This portrays the ‘id’ and the ‘ego’ theme behind the novel. Although they are a perfect carbon copy of each other, stronger impact is created as we see the personality differences between the two, become more prominent as the story progresses. Lennie contains the ‘id’, also known as the desire, to do what he wants to do. George is different, as he contains the ‘id’ and ‘ego’ personality. He has the knowledge, the ego, to know whether his id is right or wrong. At the start of the novel, the two men are in a place called Weed. They are forced to leave there, when they are being hunted down. This is because Lennie had clutched the dress of a girl, and would cease to let go. The girl shouted rape, and so if they were to live, they must leave, and seek life in another location. Lennie was more enthralled and fascinated at listening to George tell him about the dream, and what they would own and how they would do things, rather than actually thinking about all of the things happening in reality. He knew what the dream was exactly, but he was more excited, when George told him: â€Å"Why’n’t you do it yourself. You know all of it. / No †¦ you tell it. It ain’t the same if I tell it. Go on †¦ George. How I get to tend the rabbits†. The story in the novel is based around the ‘American Dream’. That is the dream in which every man could strive for in the great country. The dream of all the ranch-hands was stability and eventually a place of their own. This place offered a hand of friendship and companionship, that Candy and Crooks along with George and Lennie all craved. The dream offered security, and equality, as well as an end to social injustice. This for some, was impossible to attain. For George and Lennie, the dream could be seen as ‘wishful thinking’. The dream is simply wanting to re-create happier times as a child, when George said they would have pigeons: â€Å"An’ we’d keep a few pigeons to go flyin’ around the win’mill like they done when I was a kid†. He wants to keep the good memories from his childhood alive, by re-enacting them. They also dream of paradise, with lots of different foods. They will either eat the animals they raise, or will hunt for their food: â€Å"†¦an’ when we kill a pig we can smoke the bacon and the hams, and make sausage an’ all like that. An’ when the salmon run up river we could catch a hundred of them. We could have them for breakfast†. They also thought about the authority and the power that they would now have, instead of having to confirm to the power of others: â€Å"If we don’t like a guy we can say: ‘Get the hell out,’ and by God he’s got to do it†. For once in their lives, they would be able to appreciate the needs of human beings. They would have their own home, and friends could stay: â€Å"An’ if a fren’ come along, why we’d have an extra bunk, an’ we’d say ‘Why don’t you spen’ the night,’ an’ by God he would†. Lennie talks about the dream in front of Candy, and Candy becomes very interested. Candy is old, and lonely. He is lonely as his dog, which suffered from rheumatism and old age was laid to rest, and Candy wishes the same of him, as he feels exactly the same, as his dog must have felt. He lost his hand on the ranch, and so he was given the job of swamping. Candy was given two hundred and fifty dollars for his injury, and the money may actually bring George and Lennie’s dream as close to reality as it has been so far. â€Å"An’ they give me two hundred an’ fifty dollars ’cause I los’ my hand. An’ I got fifty more saved up right in the bank, right now†. Candy is prepared to offer up the money, but he makes it perfectly clear that he wouldn’t ‘own’ the ranch, just because he had the highest stake. He is quite prepared to live away from that ranch, he has spent so long at.

Bus 599 Paper

Master Degree in Business Administration Strayer University Strategic Management BUS 599 Assignment 3 Submitted in Partial Fulfillment of the Requirements for the MBA program Abstract Through this paper, one will understand the trends in the global beer market. There will also be the possibility of Modelo’s international expansion. There will also be an assessment about the next foreign market that Modelo should get involved with. A decision about the challenges that Modelo faces from their competition InBev and how Modelo should respond to this beer industry giant is presented in this paper. Last but not least, a discussion about weather or not Modelo should diversify their business is stated in this paper. Historically, the brewing business was known as a local industry. Furthermore, only few of the brewers were known at an international level. During the past decades, there were a lot of consolidations done within the beer industry. With the past few years, the process of global beer consolidation grew even higher. By the year 2008, there were two major acquisitions made within the global brewing industry. The two acquisitions were made of Scottish and New Castle by Carlsberg and Heineken. The other acquisition was done of Anheuser-Busch by InBev. (www. carlsberggroup. com). The trend of beer over the last five years had a combined annual growth rate (CAGR) of 4. 8% worldwide. (www. encyclopedia. com/doc/1G2-2843300064. html. ). Within Central America and South America, the CAGR increased to 6. 3%. Africa also showed growth by having CAGR that got up to 6. 4%. A key note about the growth of beer was shown in Asia. www. encyclopedia. com/doc/1G2-2843300064. html). The trends of beer for the last five years have being tilting toward consumers wanting expensive beers. Due to that, expensive beers or premium beers accumulated 17% of the beer sales globally. The premium beer market of North America as well as Western Europe sales happen to be higher than the global average for premium beers. www. carlsberggroup. com/company/market). Due to the high economic downturn, the consumption of prem ium beer became very low. Grupo Modelo happens to be the most popular and largest makers of beer in the country of Mexico. Over the years, this company has strived for excellence and became the 12th largest producers of beer in the world by 1998. (www. businessweek. com/globalbiz/content/aug2008/gb20080814_195868. html). Grupo Modelo’s most famous brand of beer is the Corona Extra. Corona Extra was noted as the first among imported light beers within the United States in the year 1997. Moreover, Corona Extra was ranked the fifth in light beers worldwide in 1997. Grupo Modelo is the producer of nine brands of beer within their company. Modelo mission is to â€Å"produce, distribute and sell quality beer at a competitive price, optimizing resources and surpassing customers’ expectation in order to contribute to the social development of Mexico. † (www. gmodelo. com. mx). Due to North America’s Free Trade Agenda (which eliminated barriers as well as tariffs) Modelo made a strategic business move that involved protecting themselves from having to deal with U. S. beer taking over their sales in Mexico. Moreover, Grupo Modelo Company decided to become partners with Anheuser-Busch. The deal of partnership with Anheuser-Busch allowed Modelo to be an exclusive distributor of all the Anheuser-Busch products in the country of Mexico. Within the United States, four different brands of beers produced by Modelo were sold and distributed by Barton Beer. Anheuser-Busch did not distribute any of Modelo’s beers within the United States. With the partnership of Modelo’s and Anheuser-Busch, Anheuser-Busch was not doing very well in Mexico. Moreover, Anheuser-Busch beers (Budweiser and Bud Light) during that time of the late 90’s were only selling well in tourist areas within Mexico. Due to this discouraging fact of Anheuser-Busch only doing well in tourist areas of Mexico, they decided to raise their equity in Grupo Modelo to 37% in 1995 and proceeded to raise equity to 57% in 1997. By raising their equity in Grupo Modelo to 57%, Anheuser-Busch total investment came up to about $1. 6 billion. Modelo decided in 1996 to renew their alliances with Barton Beers and Gambrinus for a decade. This decision made by Grupo Modelo angered Anheuser-Busch and brought about mistrust in decision making by Modelo. By the year 1997, Grupo Modelo had 80 percent of all Mexico beer export. In addition, Modelo was exporting there brand of beers to 143 countries. (www. businessweek. com/globalbiz/content/aug2008). Although Modelo is well known for their brand distribution of Corona Extra and Corona Light, they also distribute other beers such as Modelo Especial (this happens to be Modelo’s second leading brand of beer), Victoria, Light Modelo, Pacifico, Estella, Leon Negra, Montejo and Negro Modelo. It is a proven fact that Modelo has done very well within the United States beer market and is still having continuous success in Latin America. The Next foreign market Modelo should step into must be the Asian market. This continent is understood to be huge consumers of beer, coming second after Western Europe. Modelo should try and make alliances with the top seller of beer within each Asia nation. Modelo should also try to relinquish their strong Latin background and try to incorporate them into the Asian culture. Although it is an applauded agenda for a business to strive for uniqueness, it is also a sensible idea for a business to be adoptive. Moreover, Modelo will have to send agents that will evaluate the business environment of Asia in order to know their style and likings when it comes to beer. Instead of concentrating on making huge profits by selling their products at high prices, they should focus on quality and make their product available for a reasonable price. This will enable the buyers of the beers realize the beer taste and then become a loyal customer. Modelo should also try to work together with local brewers within Asia. Modelo should also invest in advertisement and avoid having to make known to customers in Asia their beer rank number one in Latin America. Moreover, the focus should be on becoming the number one distributor of beer in Asia. Modelo should also seek to built factories or plants within Asia in order to do away with export prices and the trouble of transporting the beer. Building a plant in Asia will make their business seem more intoned with the Asian culture and allow Asians to look upon this company as one of their own. Normally, when a company presents itself as an outsiders, they tend to have a difficult time adjusting to their customers. If Modelo follow this strategy of adapting to the way of live by their customers in Asia, they would not have such a difficult time selling their products. Although Modelo is known as the most successful beer distributor in Latin America, this company still has to deal with competition. One major competitors of Modelo is InBev. InBev is a Belgian-Brazilian brewer that took over Anheuser-Busch for $52 billion. Furthermore, 50% of Modelo is owned by Anheuser-Busch. This puts Modelo in a difficult predicament. Modelo also stands at a disadvantage because InBev bought Anheuser-Busch and Anheuser-Busch owns fifty percent of Modelo. The strategic response Modelo can imply to the competition of InBev is to pay out Anheuser-Busch, so Modelo can once again decide their business agenda without any interference. This seems to be the best strategy for Modelo because Anheuser-Busch will always cater to InBev because that’s who owns their business. Furthermore, Modelo needs to focus on maintaining their reputation as the best beer distributor in Latin America. The only chance InBev have of taking that title away from Modelo is by buying Modelo. The Corona Beer is still a success worldwide as well as in Mexico and Modelo needs to consider that fact as an advantage. Diversity in the â€Å"world of business† is always a good thing. Furthermore, it enables a business to grow and get more customers. Modelo should diversify their business. Modelo should consider getting into the soft drink business. This is a way to gain a larger consumer base. Although Modelo is doing well selling beers in Mexico, a lot of Mexicans don’t drink alcohol or are underage to consume alcohol. Getting in the business of selling soft drinks would be a very smooth transition because Modelo is a popular a successful company.

AIDS identified 1981 Essay Example | Topics and Well Written Essays - 1000 words

AIDS identified 1981 - Essay Example , the United Nations, and the Center for Disease Control and Prevention (CDC), as well as those in the national and local levels have remained troubled of the effects of this condition as millions continue to contract the virus and die every year. In fact, the United Nations recorded 2.7 million new cases of HIV infections worldwide in the year 2008 and noted almost three-quarters of this number have died an AIDS-related death in the same year (â€Å"The Global AIDS† 1). As it worries the authorities and the total population of the current times, this paper intends to tackle how the condition was discovered and how it has affected the history since then. AIDS first came to view in the early 1980s when a number of homosexual men presented a kind of ill health condition which had not been identified in the history of the medical field Practitioners in Los Angeles, New York, and California have linked and treated the unknown condition with mononucleosis, cytomegalovirus, and other related conditions with their designated treatments as supported by the signs and symptoms seen in the patients (Grmek 3-5). The homosexual men who went to Joel Weisman showed â€Å"hectic fever, weight loss and swollen lymph nodes† (Grmek 3). A New Yorker also presented the same condition when he illustrated â€Å"lassitude, weight loss, spiking fevers, and slow consumption of the body† (Grmek 5). However, despite the attempts to counter the symptoms observed, no improvements became visible. Grmek even pointed out that two of Weisman’s patients â€Å"treated since fall of 1980, went from bad to worse† (4). After a number of labora tory works, the cause of the involvement of some opportunistic infections such as Pneumocystis carinii pneumonia were attributed to the â€Å"reduction in the population of lymphocytes, due to the almost complete disappearance of the helper T subgroup,† components of the immune system that helps fight infection (Grmek 4). This decrease in efficiency for immune

Arguing to Persuade Essay Example | Topics and Well Written Essays - 1000 words

Arguing to Persuade - Essay Example Argument to persuasion invites more use of language resources than argument to persuade (Caine 54). A persuasive paper intends to use logic and reasoning to convince others abandon their stands and beliefs and be conformed to the writers views). In this regard, this writing prior to preparation is necessary. There are stipulated steps that, if followed would result to a high performing persuasive paper. To begin with, an author should choose a certain stand (Wachob 34). Before one embarks on convincing others about his point of view, he or she must be sure of what he or she believes. Understanding and analyzing the audience follows; after this, the writer must delve into serious research on the topic. This enables one form concrete decisions, explanations to every statement and also boosts personal confidence and esteem. It is also in this level that one understands the failures of former works in the topic and develops mechanisms to counter them. The research on the topic also helps indentify reliable and legitimate sources of information and experts on the same. From the research plane, one is to develop a hypothesis, a proposition, a claim on the topic. The hypothesis should be debatable, carry with it two opposing ends. One can resort to having a thesis that stands against his or her stand, doing this ensures that the claim is debatable. The next move is to try and extrapolate possible refutations against your stand. This stage can be meant to do two things, prepare one psychologically to defend his or her stand and prepare answers to the refutations citing legitimate and available evidences (Forsyth 23). The next point is to provide concrete reasons for a particulate stand. This can be done by providing evidences by the use of facts, statistics from dependable sources and by the use of illustrations and examples. There are elements of a good persuasive writing. There should be order of how things get presented. This allows a clear flow of information witho ut conflicting of ideas, facts and truths. To start with is the introduction of the paper. This part gives an oversight of the paper and should not to be too lengthy. Terminologies in the topic of the paper should be defined and be explained at this point. Explanation of the background of the paper can also be given in the introduction (Caine 64). In the end of introduction, the claim should be introduced in a clear and precise way. The thesis can tell the reader the actual topic of the paper and the organization of the paper After introduction and having stated the thesis, the next thing in line is defending the thesis by providing evidences. This happens in the body of the paper and should take a minimum of three paragraphs. The thesis carries the whole paper. At this point, it is healthy to have the extrapolated refutations in the fingertips so as to start countering them from the very first defense. The paragraphs should also be arranged in accordance with the weight of the evid ences, starting from the beast to the least. The last statement of the paragraph should also be able to link with the next paragraph in a manner that embraces a perfect flow of information. (Wachob 39) After a perfect statement of the writers evidences, the paper should proceed to a new paragraph or segment that purely focuses on refutations. Since the writer communicates through writing, he or she is denied the chance of getting

Analyse the competitiveness of Danish manufacturing Coursework - 1

Analyse the competitiveness of Danish manufacturing - Coursework Example cks here according to research is that regardless of what is measured by production, total employment and value added, the manufacturing industry have portrayed a declining importance. Cluster is taken positively by the Danish, since it is termed as a competitive advantage of nations. Here, Clusters got a prominent role due to the theory of competitive advantage of nations first witnessed in the year 1990. With its strategy, that involves a geographical interconnection of companies, service providers and specialized suppliers and organizations in industries that are related and associated it can be noted that clustering strategy have made the country to move at per, with other European countries in terms of production(Daugherty, 2009.p.75). Clustering channel is better explained by the following diagram. The industrial production is divided into hundred main components. The first one, accounts for the highest output in the country, and that was in the year 2011 which accounted for 74 percent. While, mineral fuel accounts for sixteen percent while all the mechanicals, boilers and machinery accounts for almost ten percent (Daugherty, 2009.p.102). They all cluster to give out a whole 100%. The comparison of 2000 and 2011 years, illustrates that the country faced subsidized electrical production equipment. From the manufacturing side to the purchasing side, the clustering in production of this equipment was studied as deeming. This is why; the whole Denmark affirms that the electrical part portrayed a downing advantage (Hadjilambrinos,
