Key Controls in Securing Cyber-Physical Systems (CPS)
Summary: Dragos summarizes SANS Institute guidance on securing cyber-physical systems, which it defines as OT, IT, IoT, and IIoT devices combined in industrial environments where digital technologies directly affect physical operations. The controls it lists are hardening the environment and managing access with multi-factor authentication and encryption, maintaining asset visibility and inventory, prioritizing vulnerabilities by operational impact, continuous monitoring with OT-specific threat intelligence, and OT-tailored incident response plans tested through tabletop exercises.
Bottom line: Dragos notes that IoT devices such as sensors and cameras are often insecure by design, lacking strong authentication or encryption, and are frequently exposed to the internet, while state-sponsored groups and ransomware gangs target IT as a launchpad for lateral movement toward OT assets.
