Security Games for Cyber Resilient Bulk Power Systems
September 29, 2017
Abstract: The extensive use of information and communication technologies in Bulk Power Systems (BPS) make them vulnerable to cyber-attacks. One class of cyber-attack is advanced persistent threats where highly skilled attackers can steal user authentication information and then move laterally in the network, from host to host in a hidden manner, until they reach an attractive target. Once the presence of the attacker has been detected in the network, appropriate actions should be taken quickly to prevent the attacker going deeper. This presentation presents security games approach to optimize the defense of the BPS against an invader attempting to use a set of known vulnerabilities to reach substations.
