Abstract

In this paper, we suggest a flexible type-2 fuzzy set algorithm for analysing anomalous behavior trends of some system parameters. This algorithm can be implemented in a performance-based Artificial Immune System (AIS) and used as anomalous behavior recognition engine for a biological-inspired Intrusion Detection System (IDS). The suggested algorithm is based on the idea that real-world applications have the necessity of providing a strong, reliable discrimination between normal and abnormal behaviors but such discrimination is not always well-defined. This fact introduces many degrees of uncertainties in rule-based systems and convinced us to implement a type-2 fuzzy set algorithm that can easily manipulate and minimize the effect of uncertainties in our system.
