A new guide, Principles of Operational Technology Cybersecurity, has been released by the Australian Cyber Security Centre (ACSC) in collaboration with CISA and international partners.  The guide provides crucial information for organizations aiming to secure their operational technology (OT) environments, particularly those in critical infrastructure (CI) sectors. It outlines the following fundamental principles designed to help companies manage risks and protect against cyber-threats in their OT systems: Safety: Prioritize safety to prevent life-threatening risks in OT systems, Business knowledge: Understand critical systems and processes to secure them, Data protection: Safeguard valuable OT data, especially engineering configuration data, Network segmentation: Isolate OT networks from IT and external connections, Supply chain security: Ensure suppliers and vendors meet security standards, Skilled personnel: Train staff to monitor, identify and respond to OT cyber incidents
