buy custom Computer Security Threats essay Computer security refers to the detection and prevention of any unauthorized access to your computer as noted by (Himma, 2007, p.79). Detection process helps to determine whether some users tried to access your system. It is concentrates on the confidentiality, integrity, where only those authorized have the right to access that information and availability of the information to those who need it. Connection of personal computer to any network or Internet exposes it to malicious programs, stealing of valuable information like passwords by hackers or construction of DOS (Denial of Service) attacks that may limit computer user from access to websites and other services (Fragouli Emina, 2006, pp. 125-128). A hacker on the other hand, is an intelligent person capable of creating codes, breaking into large networks and stealing confidential information, modifying and, corrupting programs to perform some tasks other than what its expected task according to (Holden, 2003, p.140). The aim o f this study is to identify security threats home PC and techniques that the attacker uses to access the information. Firstly, in the past, the domain name system found its use in providing different expandable systems. This system has to be integrated such that it does not allow phishing and spam in its network (Himma, 2007, p.89). The DNS are more vulnerable to attacks such as DDos and the cache poisoning. The DOS attacks are typically, observed in on web pages that exhibit top page ranking servers, such as the banks, institutions to some extent the credit cards gateways. The expansion of the Internet protocol also may cause danger to the Internet users. This calls for expansions of Internet protocol versions (IPv) so that they may provide packet switching of the Internet working. The expansion allows the eliminations of using the network address translation (NAT). Essentially, subletting may be used to avoid the packet collision. The hackers would always make their systems assume the false negative of false positive. This happns on spam information in most cases. Spam would test to be false negative, yet in the real sense, it is not a spam. In addition, spam may also test to be false positive yet, it is not a spam. This makes the hackers to bypass the systems, thereby causing a security threat. Examples of potential security threats to home PCs include Broadband Internet Connection; DSL and Cable Modem which affects both the home PC users and other operating system users (Holden, 2003, p. 145). They enhance unauthorized access from the Internet to a host network. Malicious codes and programs affect Dynamic Host Configuration Protocol (DHCP) and contain virus, worms and Trojan horse, which endanger accessibility of data and information. Virus, which is a code created to something in your computer other than what was expected. Virus can delete all the information on hard drive and sometimes replicates itself which would corrupt the PC. In addition, a worm on the other hand multiplies itself but, does not corrupt other files. Hackers also use virus hoax to give a warning for an individual not to open particular attachments through the Internet or, even send mails. Trojan horse on the other hand, makes the user believe that, a particular program is harmless but, it accesses a computer without the user knowledge. A Trojan horse does not replicate itself but delete files from the home PC. According to (Holden, 2003, p.143), in DDOS (Distributed Denial of Service), home PCs are used as a base for attacking other systems while Denial of service (DOS) result in crashing of the computer making it hard for the user to access it. Email spoofing impersonates a user to reveal confidential information since, it frauds the email from an illegal sender to appear as if it comes from a legal sender. Worms can also be spread to home PC through email attachments. Unsecured windows file sharing in Local Area Network (LAN) enhances spr ead of malicious programs and codes to other computers connected to the network (Levine Shields, 2006, p. 279). Packet snifffing is used to represent data on the network and decodes the layers of file extensions making the user execute malicious codes. Some of the techniques that are used by hackers to access unauthorized information include; pretexting where a pretext is created to make the user to reveal valuable information by engaging an individual to perform an action which is unlikely to be done under normal situation (Himma, 2007, p.124). An intruder prepares answers that are likely to be asked by the victim and uses an authoritative voice. In diversion theft, the user is compelled to give the information to other sources that disguise to appear like the true recipient. In Phishing technique, an email is sent requesting for the verification of confidential information and appears to be like from the legal source; like a bank logo after which the user may disclose confidential information. In IVR (interactive voice response) or phone phishing, a user is prompted to call a certain source and, may be asked to enter particular details severally for verification purposes. The user would be put on bait with devices like, flash disks dropped at strategic points, with extremely catchy labels which, when used on home PC, it can affect the computer e.g. installation of malware. An attacker may use the phone to call different people claiming to be from a genuine source after which any person with such a need will fall to be the victim. In conclusion, home users should be aware of the threats facing their home PCs and, should be alert and have knowledge of the security threats as noted by (Levine, Shields, 2006, p.267). The internet service providers should also come with mitigations that are capable of counteracting these cyber crimes. This may be by thorough encryption of the content conveyed, and continuous surveillance of any abnormally (Fragouli Emina, 2006, p. 128). These measures should curb how they are spread and, the appropriate measures that should be taken to fight against unauthorized access to their computers. Buy custom Computer Security Threats essay

ANSWERS TO SOME FREQUENTLY - Dissertation Example 2. WHAT IS THE SCOPE OF TRANSACTIONS TO WHICH THE BAN ON RIBA IS APPLICABLE? DOES THE TERM APPLY ONLY TO THE INTEREST CHARGED ON CONSUMPTION LOANS OR DOES IT ALSO COVER PRODUCTIVE LOANS ADVANCED BY BANKING AND FINANCIAL INSTITUTIONS? The Shariah clearly states that riba al-nasi'ah, â€Å"the fixing in advance a positive return on a loan as a reward for waiting† is prohibited. Hence it could be understood as a ban on interest as commonly used today. Islamic jurists, the fuqaha, state in no unclear terms that all manifestations of riba are forbidden. So it does not matter if the context is consumption or business and also whether the loan in issued or availed. It is also irrelevant whether the institution in question is a commercial bank, government agency, business enterprise or an individual. 3. DOES THE PROHIBITION OF RIBA APPLY EQUALLY TO THE LOANS OBTAINED FROM OR EXTENDED TO MUSLIMS AS WELL AS NON-MUSLIMS? The Islamic Fiqh Academy (IFA), which is the leading authority on f inancial transactions, mentions that there is no leniency in the application of Shariah laws even if one party of a financial transaction is non-Muslim. ... IS SUCH A SCHEME ACCEPTABLE FROM AN ISLAMIC POINT OF VIEW? In economies with high rates of inflation, restrictions imposed by Shariah laws can undermine value of investments. To compensate for such a loss, a method of indexation is usually employed. There is no consensus yet among the fuqaha, as to the compatibility of indexation practices with Islamic scriptures. So far the Fiqh Academy has permitted indexation in cases pertaining to â€Å"wages and contracts fulfilled over a period of time† and has disallowed in cases pertaining to monetary debts. Similarly, â€Å"for debts in a specific currency, due in installments, the parties may agree to settle the installments due in a different currency at the prevailing rate of exchange on the date of settlement†. 5. WHAT ARE THE MAJOR MODES OF FINANCING USED BY ISLAMIC BANKS AND FINANCIAL INSTITUTIONS? Islamic banking system has invented a few ingenious modes of financing in order to comply with Shariah principles. The first mode is based upon sharing of both profits and losses incurred by investments, respectively the mudarahab (passive partnership) and musharakah (active partnership). The second mode operates on the basis of credit offered durig the purchase of goods and services and uses such financial concepts as murabahah (sales contract at a profit markup), ijarah (leasing), salam and istisna (contracts). These modes are unique to Islamic finance and have been approved by fiqh officials. Apart from being consistent with Islamic precepts, these modes incentivise direct investments, thereby contributing to economic growth of the bank/institution/country. Yet, improvements need to be done in order to integrate Islamic financial system into global

Planning and Organising International Business Enterprise in Russia Essay

Planning and Organising International Business Enterprise in Russia - Essay Example Longwell also estimated that to meet the expected demand almost 80 million oil-equivalent barrels might need to be added per day and this need to be done by 2010 (Longwell, n.d.) Demand of natural gas is increasing rapidly because world is looking for more environment friendly, efficient and clean energy source. So it is quite clear that there are huge business opportunities worldwide for the oil and gas exploring companies. There are many companies dealing with oil drilling technology, but most of these companies are from USA. It is a fact that Russia is one of the leading exporters of natural gas and oil. As far as oil reserves are concerned Russia is eighth in the world but the country is holding first position in terms of natural gas reserves. Saudi Arabia, largest oil exporter in the world, is the major competitor of Russia as far as oil exporting is concerned. In the field of natural gas Canada, United States and Norway are the major competitors of Russia as they also produce and export large amount of natural gas. So it can be assessed that the upcoming firm would face international competition to great extent. Even few years back, the technical aspects of oil drilling like horizontal drilling and hydrofracs were primarily provided by western nations but today many of the Russian companies also provide the services. The geographical environment is primarily favourable to the prospective oilfields in Russia as the country has vast resources of nature like oil, coal and natural gas. Most of the oil reserves in Russia are located in the Siberian region. But various factors like climate, distance and terrain act as obstacles in the process of exploration and production of oil and natural gas in the region. As far as economic conditions are concerned in 2008 Russia’s GDP growth rate was 5.6%. Since 1998 Russia had been able to retain its average growth rate at 7%. Major portion of its GDP comes from export of oil and natural gas. Country has almost

I just hope it’ll put Rechner away†¦Ã¢â‚¬  â€Å"Next time we will see him we will all say AFGOI at once,† suggested Vanessa. They waited patiently to see the evil Rechner again so they could use the magic word to free Jayden. Several days went by and the time was passing very quickly at camp. Every day was full of activities. At the end of the week Sam, Vanessa, and Alex all decided to go sailing because of the water skiing accident. Alex did not want to water ski again. Neither did Vanessa after what happened to Alex last time. They kept wondering when Rechner would appear again. After spending time on the lake, it began to rain cats and dogs. They ran for shelter under a pavilion and were glad that they were off of the sailboat. Sam said, â€Å"Why don’t we head towards our cabin and call it a night.† Alex and Vanessa agreed. They began their long trek to reach the cabin. The ground was very soggy and muddy and they all got their shoes extremely dirty. They were all happy to hit the hay for a good night’s sleep. Their counselor stayed up to watch them to make sure they didn’t leave again. In the morning their counselor was exhausted so he let the campers sleep longer than usual. When they awoke, they all were starving and their entire cabin headed to go eat. After breakfast Alex, Vanessa, and Sam went back to the cabin to brush their teeth and that is when the evil Rechner finally appeared. All three of them said AFGOI at once and Rechner said, â€Å"Okay I give up and you win. Jayden gets to go back to her palace.† Alex, Vanessa, and Sam couldn’t believe what they just heard. Everyone that lived in Idyllia was so happy to have the Emerald Queen back. They pushed nine hundred dollars out of the book. Alex, Vanessa, and Sam were so excited because Jayden was now safe and they each had three hundred dollars. They were finally done with Rechner once and for all! Jayden’s Rescue Written By: Vladimir Tumanov Project by: Schmo went through 2 green lights. Mane went through 1 red light. Torch went through 3 yellow lights. This is 6 lights in all (2+1+3). Then they repeated the same path so 6+6= 12 lights passed. Torch went through 3 yellow lights twice so 3+3 = 6. Each ticket was $300 so 6 lights times $300 is $1,800. He only had $100 bills so you need to divide $1,800 by $100 and you get 18. Torch passed 4 ponds which each had a duck. These 4 ducks bit his hand each one time and each bite caused 4 red bumps. So 4 bites times 4 red bumps each is 4 x 4 which equals 16 red bumps.

Presence Of Angels :: essays research papers

There is a certain mystery that lies within the meaning of angels. It is known that angels are among us. They are carriers of the messages from God (Gasparri 14). However, little is known about what and who angels are, why they are present, and even what they look like. They everything that human want to be and more (Stevenson 1). Angels go above and beyond the limitations of humans to give hints of what life is like in heaven or even hell. What are Angels?   Ã‚  Ã‚  Ã‚  Ã‚  There are three creatures created by God. Humans, created with free will that can be used for good or can be used to cause hurt and destruction, are the first of these creatures. Second, come angels and devils. Angels are creatures of God with free will that chose to accept God’s love and goodness. Devils are the exact opposite of angels. They used their free will and chose to go against God. The last of the creatures are animals. (Gasparri 75-77)   Ã‚  Ã‚  Ã‚  Ã‚  Angels are divine beings chosen by God to deliver His love and goodness to humans. They are “entities'; of goodness and holiness (Stevenson 4). Angels are equipped with supernatural powers that allow them to rarely be seen by the human eye. Any scientific terms or proof cannot explain their existence. Those who believe in the existence angels are those who have already experienced their presence (Stevenson 5). The Catholic Perspective on the Kinds of Angels   Ã‚  Ã‚  Ã‚  Ã‚   Catholics believe that angels have a special role of praying to God on behalf of humans. They are “messengers';, carrying hints or signs from God to his kingdom (Stevenson 195). Four angels are recognized in the Catholic Church. They are referred to as the archangels: Michael, Gabriel, Raphael, and Uriel. There are many stories about the works of Michael, Gabriel, and Raphael, however, little is known about Uriel. The Bible also recognizes a number of groups of angels with different functions and attributes called the hierarchy. Different faiths recognize the different groups. The groups include seraphim, cherubim, thrones, dominions, virtues, powers, the principalities, archangels, and angels (Stevenson 20). All together, the groups are known as the choir because they are said to praise God through song and music (Stevenson 21).   Ã‚  Ã‚  Ã‚  Ã‚   While the Bible does not recognize the functions of each of the groups, each group has its own unique character and purpose. Seraphim are the angels who are considered to be closest to God.

Utilitarian Perspective On Feminism - 1563 Words

A Utilitarian Perspective on Women’s Rights John Stuart Mill’s discussion of the subjection of women leaves many scholars regarding him as one of the first feminist philosophers of his time. His work analyzes and questions the everyday perspectives on women’s rights, and challenges common societal notions. Many philosophers today look to his work for a variety of reasons; some applaud his work for being ahead of it’s time. Others dismiss it, claiming that it’s flawed due to personal attachment. Both sides however regard Mill’s writing as one filled with valid arguments, well developed points of interests, and recognizable inclusive nature. This essay’s discussion will include the basic principles of Utilitarianism, John Stuart Mill’s†¦show more content†¦As each single pursues their own pleasure, they collectively contribute to a happiness for the greater good. Though their use of avoidance of pain, they each subdue unh appiness in the overall society. This collective contribution not only betters the societies pursuit, but promotes the allowance of individuality rather than conformity to solidarity. Mill’s utilitarian description provides a greater understanding for his further analysis as a philosopher; most notably in his arguments regarding women s rights. Now that his concept of Utilitarian thought is greater understood, one can begin to identify John Stuart Mill’s points of discussion in his work The Subjection of Women. Mill clearly states that the current standard of living is wrong itself, and â€Å"ought to be replaced by a principle of perfect equality† ( Mill, 1) that does not subjugate or offer prejudice on either side. Although a somewhat unrealistic goal, Mill’s philosophical analysis actually provides some extremely contextual and concise points of discussion. One major point in his argument occurs in his discussion of women’s roles in history. Mil l’s analysis of a lack of feminine power throughout the historical context of western culture is one that is referred to by modern feminists today. His claim of female repression as â€Å"a single relic of an old world of thought and practice† (Mill, 12) provides tremendous proof of historical accuracy, regarding the questionable structural integrity of religiouslyShow MoreRelatedImpact of John Stuart Mill’s Philosophies on Philippines’ Society, Politics and Economy1093 Words   |  5 PagesStuart Mill’s Philosophies on Philippines’ Society, Politics and Economy Mendoza, A.; SocSci 2 WBYDX John Stuart Mill’s social, political, and economic philosophies are widely applied in the Philippine setting.
