Fuzzy Approach for Intrusion Detection System: A Survey

Abstract

Secured data communication over internet and any other network is always under threat of intrusions and misuses. Intrusions pose a serious
security threat for the stability and the security of information in a network environment. An intrusion is defined as any set of actions that attempt to
compromise the integrity, confidentiality or availability of a resource. It includes attempting to destabilize the network, gaining unauthorized access
to files with privileges, or mishandling and misusing of software. Intrusion Detection System (IDS) have become a needful component in terms of
computer and network security. The goal of intrusion detection is to monitor network activities automatically, detect malicious attacks and to
establish a proper architecture of the computer network security. Fuzzy logic dealing with vagueness and imprecision has a capability to represent
imprecise forms of reasoning in areas where firm decisions have to be made in indefinite environments and is found to be appropriate for intrusion
detection. This paper surveys the various IDS and the fuzzy approaches to IDS.
