HOW TO BUILD AN OT SECURITY OPERATING MODEL

Summary from the TLDR InfoSec newsletter

An implementation guide breaks an OT security program into six components, beginning with asset discovery and process context mapping that tie every device to the operational process it supports. Availability and process safety outrank confidentiality here, so access boundaries, monitoring, incident response, and recovery each require joint sign-off from operations before deployment. Ownership belongs to a cross-functional executive such as a CISO or VP of Operations, with NERC CIP and NIST SP 800-82 treated as checkpoints rather than as the program design itself.
