...Network Security Abstract: To begin to understand network security it is best to look at the basic definitions. A network is defined as “a group of two or more computers linked together”. An attack is defined as “an aggressive and violent act against a person or place”. Lastly, security is defined as “the state of being free from danger or threat”. Since the beginning of networking there have been users out there with malicious intent to either gain information or disrupt it. Technicians may not be able to stop the initiation of attack but there are certainly tools and techniques to fight back. This paper will discuss the protocol layers of networking, the associated threats and applicable solutions. This research paper will include an analysis of networking and examples of attacks. While not all solutions will be touched upon, this paper will give you a basic understanding of the way forward. Many references sited in my research are scholarly, peer reviewed journals and are considered experts in their field of Information Technology Technology is the basis of many operations in society today. While technological advances have made numerous processes easier and faster, it has also introduced an equal number of negative practices. This paper will discuss the theoretical model of networking which breaks up the data transmission process into multiple layers. We will first take a look at the original networking model and its functions compared to the newer model. Next we will...
