In today’s world, with so many ways to gain unauthorized access to someone’s computer system, network security is very important. Almost every company has been a victim of a virus attack, hackers, or some other form of unauthorized access to their network. In this paper, I will discuss various methods that those who want this access use and ways they can be prevented.
Identify hardware and software needed to secure your choice of networks against all electronic threats.
Although the organization has already tackled and overcome several significant security failings which have resulted in the exposure of its network infrastructure to various vulnerabilities, as these failings became public it has caused significant damage to the perception and reputation of Advanced Research. As a result there is a clear need to develop, define, and implement an enhanced network topology and infrastructure in order to ensure that all critical functions are protected and that there is no possibility of unauthorized access to the network or any service being obtained. Following an analysis of previous incidents it is apparent that there are several recurring areas which would need to be protected and these should be considered
To effectively assess the security needs of an organization and to evaluate and choose various security products and policies, the manager responsible for security needs some systematic way of defining the requirements for security and characterizing the approaches to satisfy those requirements. This process is in a centralized data processing environment LANs and WANs. Even for relatively small organizations, information system assets are substantial, including databases and files related to personnel, company operation, and financial matters. The information system environment is complex field including a variety of storage systems, servers, workstations, local networks, and Internet and other remote network connections. A range of threats always growing in sophistication ways.
In another recent event, there was a “ aDDos attack on government agencies and commercial Web stores in the United States and South Korea where a third of them over fourth of July weekend in 2009”. It is now obvious of our necessary need to be protected while on the internet that is why a relatively new field called computer network security has emerge. The proper definition of computer security is as follows :
Security encompasses a number of areas; it includes physical, operational, communication and networks. Each area has distinct elements and will have some overlapping points; it’s hard to fully achieve one without affecting the others (Whitman & Mattord, 2013). Physical security is straightforward; it deals with the tangible assets, which includes the people, equipment, and facility. The protection of the typical day to day activities of the office or manufacturing environment to complete or produce products is operational security. Communication in today's organization is a necessity, especially for public a company, the methods and content must be guarded just like assets. Network security is one area most people focus on, these paths or channel both internal and external include all the devices and data that information flow through.
Computer security has been important since the creation of the Internet. Still, Steven L. Shaffer and Alan R. Simon describe it as being one of the largest difficulties with which the computer technology industry is confronted today (21). Computer Security is “the generic name for the collection of tools designed to protect data and to thwart hackers” (Stallings 1). It is important to guarantee such security to protect data while it is transmitted. When there are many computer security services in a network, the transmission of information has to be ...
There are many goals of Information Security, Information Security needs to protect home users personal data as well as corporate and web environments. Information security is needed now more than ever as there has been a substantial rise in cyber attacks; cyber attacks in 1994 were a mere 2,340 and by 2001 had risen to 52,658. (Volonino, Linda, Stephen R. Robinson, and Charles P. Volonino)

Network breaches are an ever-present and growing threat to network security. There are many ways that such breaches can occur, and the following material will analyze five case studies. The issues to be addressed will include, what went wrong, how could it have been prevented, and what measures could be instituted to prevent a reoccurrence.
...work Security Article). With this given information in the essay, is a great start to learn how to keep your network secure. This is only a small part of the prevention of infiltration of your network and computer. If one desires to learn more, go above and beyond and continue to learn on how to keep your network secure.
Data went from paper to computer systems and with this new transition comes the responsibility and increasing need for network security. Whether it is the basic home computer used at home for family or personal usage or the IPad carried from work to complete projects or even the operating systems you use at work like your daily computer or in all your daily workstation. All these systems need protection. The computer system you use at home may not be as secure as the one you use at work. If the security measure you have isn’t as strong, attackers might be able to penetrate the walls of your security system and still be able to steak information from you. All data should be considered sensitive and thereby protected with the adequate measures.
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
