Show ▼
U.S. government agencies—CISA, Department of War, Department of Energy, FBI, and Department of State—published a joint guide titled *Adapting Zero Trust Principles to Operational Technology* to assist organizations in integrating Zero Trust principles into operational technology (OT) environments. The guide addresses challenges posed by increasing OT connectivity, expanded attack surfaces, and heightened cybersecurity risks, emphasizing the need to secure OT systems without disrupting critical operations. Zero Trust adoption is positioned as a strategy to prevent adversaries from compromising, manipulating, or disrupting essential physical processes controlled by OT. CISA highlights observed threat activity, such as Volt Typhoon targeting OT systems, underscoring the urgency of implementing Zero Trust architectures to maintain visibility and control over critical operations.
