In particular, the “Control Systems Defense: Know the Opponent” report warns of the increase in attacks against utilities and industrial targets by Advanced Persistent Threat (APT) groups and gathers information on tactics, techniques and Procedures (TTPs) of common threats to ICS and OT systems to help security teams strengthen their defenses.
