Abstract DIMVA2006

Intrusion Detection Systems (IDS) for adhoc networks need secure, reliable, flexible, and lightweight infrastructures for exchanging available sensor data and security event messages. Cooperation is a major concept of Mobile Adhoc Networks (MANETs). Cooperation of intrusion detection components may also help to protect these networks. The approaches and component infrastructures have to consider bandwidth restrictions and highly dynamic network behaviour. Unfortunately, existing infrastructures and communication protocols have some drawbacks for these kinds of environments. This paper describes a robust SNMPv3 (Simple Network Management Protocol) based implementation of an IDS infrastructure that connects the components of a generic MANET IDS architecture. This implementation is focused on the requirements of a military tactical scenario. For instance, the adherence of the bandwidth constraints has been shown in a traffic simulation, including all relevant protocols and other properties of a specific tactical MANET scenario and its nodes.
