dc.description.abstractThe electric energy grid is a recognized critical infrastructure. It is vulnerable to self-disturbances as well as cyber-attacks. In particular cyber-attacks can cause from mild disruptions to serious damage that may take months or years to repair. The last is a serious threat to the security of the electric energy grid and the nation. We will present the cyber-physical infrastructure of the electric energy grid and the existing vulnerabilities. We will discuss vulnerability scenarios, activities at the power industry sector to harden the system against cyber-attacks and recent research to detect cyber-attacks in real time. We present an infrastructure that enables simultaneous cyber security and operational security. The approach monitors the dynamic state of the power system and leverages this knowledge to detect (a) data attacks and (b) detrimental to the system commands (that may originate from a malicious attacker or by operator error). Commands are intercepted and authenticated on the basis of the effect of the command to the dynamics and security of the system. The overall intrusion detection system is loaded to the existing cyber infrastructure at the substations of the electric power grid. It is a distributed system and therefore it is scalable to any size electric energy grid.en_US
