An integrated security metrics framework for estimating the overall security level of mobile ad hoc networks could be used for the preservation and improvement of the security level during the whole lifecycle of a network. Building an interdisciplinary security metrics framework is extremely difficult since the exact nature of security is not known. We propose our initial ideas for composing an integrated security metrics framework, structured according to currently known security challenges in mobile ad hoc networks. The aim is to predict, as well as to monitor, the security level, concentrating on the principal effects contributing to it. In addition, we introduce an on-the-fly security level estimation mechanism for mobile ad hoc networks. The mechanism can be used to support both node-level and network-level decision making. At the node level it is possible to constantly estimate the security level to when choosing applications and communication mechanisms. At the network level, democratic voting among independent estimates originating from different nodes can be used to increase the level of security
