Cyber-threats are challenging the resilience of power systems in ways uncommon to ‘classic’ operational risks of equipment failures and natural disasters. As an example, consider an attacker who monitors operator actions after a cyber-attack and who persistently blocks any operator attempt to mitigate the impact of the attack. Such immediate reply to operator actions is deliberately constructed, thoroughly thought of, and, typically, well-funded by malicious sources. To accommodate such cyber-attack characteristics, the resilience thinking must expand into the cyber-physical domain in which power systems, information technology (IT) and operational technology (OT) are considered as one system under scrutiny.
