Abstract: Intrusion detection has over the last few years, assumed paramount
importance within the broad realm of network security, more so in case of
wireless mobile ad hoc networks. The inherently vulnerable characteristics of
wireless mobile ad hoc networks make them susceptible to attacks in-spite of
some security measures, and it may be too late before any counter action can
take effect. As such, there is a need to complement traditional security
mechanisms with efficient intrusion detection and response systems. This paper
proposes an agent-based model to address the aspect of intrusion detection in
cluster based mobile wireless ad hoc network environment. The model comprises of a set of static and mobile agents, which are
used to detect intrusions, respond to intrusions, and distribute selected and
aggregated intrusion information to all other nodes in the network in an
intelligent manner. The model is simulated to test its operation effectiveness
by considering the performance parameters such as, detection rate, false
positives, agent overheads, and intrusion information distribution time. Agent
based approach facilitates flexible and adaptable security services. Also, it
supports component based software engineering components such as
maintainability, reachability, reusability, adaptability, flexibility, and
customization.
