Modern critical infrastructures are increasingly turning into distributed, complex Cyber-Physical systems that need proactive protection and fast restoration to mitigate physical or cyber incidents or attacks, and most importantly combined cyber-physical attacks, which are much more challenging and it is expected to become the most intrusive attack. This is particularly true for the Critical Energy Infrastructures (CEI).
The power transmission and distribution grid network infrastructure lies at the very heart of any CEI. A lot of existing advanced monitoring and control technologies are able to effectively deal with either physical, either technical, or cyber- security threats at individual level. However, the reciprocal interaction and related impacts of different threats types is not adequately captured and accordingly managed. Thus to maximize security, a joint cyber-physical approach to manage CEI security becomes necessary.
