A Review: AIS Based Intrusion Detection System

Prevention of security breaches completely using the existing security technologies is unrealistic. As a result, intrusion detection is an important component in network security. However, many current intrusion detection systems (IDSs) are signature-based systems, The signature based IDS also known as misuse detection looks for a specific signature to match, signalling an intrusion. Provided with the signatures or patterns, they can detect many or all known attack patterns, but they are of little use for as yet unknown attack methods. The rate of false positives is small to nil but these types of systems are poor at detecting new attacks, variations of known attacks or attacks that can be masked as normal behaviour. In this paper we evaluate the performance of various network based IDS technique and give a bird eye over existing IDS technique and their terminology.
