Conduct cybersecurity assessments of power grid infrastructure spanning generation, transmission substations, distribution, and EMS control centers, covering NERC CIP compliance verification, IEC 61850 (GOOSE/MMS) substation protocol analysis, and synchrophasor (PMU) network security against threats like Industroyer/CrashOverride. Use for periodic NERC CIP assessments, substation automation or EMS/SCADA security reviews, or regional entity compliance audits; not for non-BES systems or generic OT assessments without power grid specifics.
