ASD’s ACSC, CISA, FBI, NSA, and International Partners Release Guidance on Principles of OT Cybersecurity for Critical Infrastructure Organizations – CISA

[[{“value”:”

Today, the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC)—in partnership with CISA, U.S. government and international partners—released the guide Principles of Operational Technology Cybersecurity. This guidance provides critical information on how to create and maintain a safe, secure operational technology (OT) environment.

The six principles outlined in this guide are intended to aid organizations in identifying how business decisions may adversely impact the cybersecurity of OT and the specific risks associated with those decisions. Filtering decisions that impact the security of OT will enhance the comprehensive decision-making that promotes security and business continuity.

CISA encourages critical infrastructure organizations review the best practices and implement recommended actions which can help ensure the proper cybersecurity controls are in place to reduce residual risk in OT decisions.

For more information on OT cybersecurity, review our Industrial Control Systems page and the Joint Cybersecurity Advisory Immediate Actions to Reduce Exposure Across Operational Technologies and Control Systems to help critical infrastructure organizations manage and enhance their OT cybersecurity.
