An architecture for intrusion detection using autonomous agents

The intrusion detection system architectures commonly used in commercial and research systems have a number of problems that limit their configurability, scalability or efficiency. The most common shortcoming in the existing architectures is that they are built around a single monolithic entity that does most of the data collection and processing. In this paper, we review our architecture for a distributed intrusion detection system based on multiple independent entities working collectively. We call these entities autonomous agents. This approach solves some of the problems previously mentioned. We present the motivation and description of the approach, partial results obtained from an early prototype, a discussion of design and implementation issues, and directions for future work
