Abstract

We propose an integrated security measurement architecture and framework for a dynamic self-organizing monitoring system based on mobile ad hoc networks (MANETs), structured according to currently known security challenges. The aim is to predict, as well as to monitor, the security performance, concentrating on the principal effects contributing to it. We introduce an on-the-fly security level estimation mechanism for MANETs. The mechanism can be used to support node-level, network segment-level and network-level decision making. At the node level, it is possible to constantly estimate the security level when choosing applications and communication mechanisms. At the network level, democratic voting among independent estimates originating from different nodes is used to increase the level of security. Furthermore, we introduce a generic security evaluation framework based on definition and decomposition of security requirements, behaviour modelling, evidence collection, and decision making. The goal of the decision making process is to make an assessment of and form conclusions about the information security level or performance of the system under investigation.
