Corporate Network Administration & Maintenance

Abstract

This project is on Computer Networking .Computer Network have become an essential tool in many aspects: human communication, gathering, exchange and sharing of information, distributed work environments, access to remote resources (data and computing power) and many more. Starting from an historical overview, this paper will give an introduction to the underlying ideas and technologies. The second half will concentrate on the most commonly used network technology today (Ethernet and TCP/IP) and give an introduction to the communication mechanisms used. Computer networks are a system of interconnected computers for the purpose of sharing digital information. The concept of a network began in 1962 when a server in Santa Monica, California. Since that time the proliferation of computers and computer networks has increased significantly. One of the most significant challenges to networks is attacks on their resources caused by inadequate network security. The purpose of this research project was to evaluate open source, free, intrusion detection systems and how easily they can integrate into an existing network. Research was conducted for this study through a review of existing literature pertaining to intrusion detection systems and how they function.
