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.
