Node-Level Information Security Monitoring for Mobile Ad Hoc Networks

Inherent freedom due to lack of central authority in selforganized mobile ad hoc networks introduces challenges to security and trust management. Arguably, trust management is the most critical security issue in mobile ad hoc networks. If nodes do not have any prior knowledge of each other, the trust establishment becomes complicated. In this kind of situations, the nodes themselves should be responsible of their own security. We propose a model for security management in self-organizing mobile ad hoc networks that is based on nodes’ own responsibility of their security and node-level security monitoring.
