Dismantle implicit trust in OT networks, CISA tells critical infrastructure operators
Summary
CISA has urged critical infrastructure operators to abandon implicit trust in their operational technology (OT) networks and adopt zero trust principles. This guidance aims to bolster defenses against threats like Volt Typhoon, which targets OT systems for espionage and disruption.
IFF Assessment
The article discusses how threat actors are targeting operational technology (OT) systems, indicating a growing threat landscape for defenders.
Defender Context
Defenders in critical infrastructure must prioritize implementing zero trust principles within OT environments, moving beyond traditional perimeter-based security. This involves robust identity and access management, continuous verification, and assuming networks are already compromised to better defend against sophisticated threats targeting essential services.
