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.
