Network attacks detection using fuzzy logic

The aim of research is to increase the network attack detection accuracy by means of fuzzy logic. This paper considers an approach to intrusion detection using fuzzy logic. The approach is based on network monitoring of the variables characteristic of different network anomalies, such as ratio of the incoming traffic to the outgoing, packet size, etc. Every type of menace is characterized by a vector of fuzzy values describing the network state when this menace is present. These vectors constitute the fuzzy rule matrix. This article proposes computation of the integral indicator of the presence of any menace using the rule matrix.
