Firewall Technology (Network Security) Research Paper

Firewall Technology (Network Security) - Research Paper Example Security requirements have substantially changed recently. Traditionally, securing a system was provided by preventing access (physical and ethically) to the secure system. However, with the introduction of computer technology, there was a need to develop automated security appliances for protecting the network and data of an organization. Due to vast rise in threats, vulnerabilities, hacking and cyber crimes, firewalls become mandatory as the first choice to implement for securing the network and data for every computer network. Firewalls Computer Security is the general term for a set of resources designed to help protect data and ruin the efforts of hackers. Moreover, it is a set of measures to protect data during transmission over a set of interconnected computer systems. Hence, security is a set measures for deterrence, prevention, detection and correction of security threats that can damage or divulge information either locally or when transmitted. Hence, certain security mecha nisms that are designed to detect, prevent and restore security after an attack. Consequently, many network appliances are invented to secure a network. The most popular network security appliance that is used in almost every small or corporate network to provide security is a firewall. Firewall is defined as â€Å"a combination of hardware, software, and procedures that controls access to an intranet. Firewalls help to control the information that passes between an intranet and the Internet. A firewall can be simple or complex, depending on how an organization decides to control its Internet traffic. It may, for example, be established to limit Internet access to e-mail only, so that no other types of information can pass between the intranet and the Internet† (Firewall.2007). Firewalls are network security devices that are categorized in hardware-based firewalls and software-based firewalls. The hardware-based firewalls are more secure, as they are not dependent on the oper ating system. On the other hand, software-based firewalls are dependent on the operating system that may demonstrate risks. The choice from these options depends on the cost as well. However, a full features firewall may protect the computer network from hackers or cyber criminals. It will detect, block and quarantine viruses and malicious codes that tries to enter in the network. Moreover, configuration on the local area network demonstrates a graphical user interface to ensure that each preventive measure is active and running (Agnitum outpost persona firewall pro 2.0.2004). Benefits Constant monitoring of security is achievable via a firewall implementation. As all modifications and logs are stored in a firewall, that are divergent of distribution on hosts on the network. Firewall also provides the protocol-filtering capability as it filters protocols and services associated with them in order to secure them from exploitation. Moreover, firewall hides inbound communication of the network from the outbound network that is also called a wide area network (ADVANTAGES OF FIREWALL). Furthermore, the use of computer networks and communication lines require protecting data during transmission. In addition, firewalls also provide centralized management for the network. This is an ultimate advantage for the network security staff within an organization as the management and

Brown v the board of education - Research Paper Example In the middle of the twentieth century,the struggle for racial equality in the United States was reaching a boiling point.Since the end of slavery,African-Americans had been fighting for the same rights and privileges enjoyed by white Americans. By the 1950s, civil rights activists were gaining ground in efforts to desegregate American society. One of the areas in which segregation was a major problem was education. Black students were not allowed to attend school with white students, and their education suffered because of it. In 1896, the United States Supreme Court heard the case Plessy v. Ferguson, and ruled that racial segregation was not illegal, so long as segregated facilities were "separate but equal."1 In 1954, the case Brown v. Board of Education challenged this ruling and led to its repudiation. Brown v. Board of Education was a landmark decision by the United States Supreme Court that paved the way for integration and significantly impacted the civil rights movement. The case was brought to the Supreme Court by the NAACP Legal Defense Fund under the leadership of Charles Hamilton Houston and Thurgood Marshall. It was actually five cases that were heard under the name Brown v. Board of Education, after Oliver Brown, who was the lead of almost 200 plaintiffs.2 The unanimous ruling in Brown stated that â€Å"separate but equal† schools and facilities were in fact â€Å"inherently unequal... to cope with ordinary expressions of prejudice by regarding the prejudiced person as evil or misguided; but he cannot readily cope with symbols of authority, the full force of the authority of the State—the school or the school board, in this instance—in the same manner. 5 These feelings of inferiority were reinforced by the entirety of the society in which black children lived. It damaged their self-esteem and subsequently their chances for success later in life. Segregated education was not only harmful to children’s education, but also to their psyches. The Brown decision meant that black students would be able to attend the schools of their choice. Black schools were not only inferior in principle, they were inferior in practice, as well. Black schools employed black teachers who, because of segregation, had not had access to good educations themselves. They received fewer tax dollars due to the economic class of the neighborhoods in which the schools were lo cated, _____________________________________________________________________________________________________ 1.

After the Brown decision, black students had access to an education equal to that of white students, resulting in subsequent generations of black teachers who could further equal education goals, in addition to black professionals who had benefitted from the educational opportunities Brown afforded them. The decision was not a popular one in many segments of the American south. Students were threatened by whites who were unhappy with the decision, and in many cases were physically blocked from entering schools
