Some challenges of critical infrastructure information security monitoring

The critical infrastructure information security should be viewed from a unified system perspective based on a unified assessment of the value of information. This implies a unified approach to assessing subsystems in terms of their ability to use infrastructure interdependencies to detect information security violations. The paper discusses cyber interdependencies in the context of information security. The main idea of the approach is to observe the consequences of the cause which is an unobservable source of actions to violate information security.
