The CyberStrike NEMESIS training workshop offers an in-depth look at the tactics, techniques, and procedures (TTPs) used by the most sophisticated cyber adversary groups targeting industrial control systems (ICS) today. Participants are guided through a series of hands-on exercises that challenge them to defend against some of these TTPs used by skilled adversaries. Cyberstrike LIGHTS OUT offered on the previous day is not a pre-requisite for taking this class, but it is helpful.
