OT security risk assessment involves automating asset discovery, vulnerability evaluation, and compliance mapping to ISA/IEC 62443 across Purdue zones. This process identifies industrial control system risks and generates governance frameworks for energy, utility, and manufacturing environments.

Purdue model network segmentation separates IT and OT traffic into defined zones using conduits to secure ICS environments. It enforces IT/OT convergence controls, DMZ boundaries, and data-diode considerations to prevent lateral movement and isolate critical infrastructure assets.

Yes, you can map MITRE-ICS techniques and NERC CIP requirements to your asset inventory. The process correlates discovered OT assets with vulnerability assessments and compliance frameworks, producing structured governance outputs that satisfy ESP/CIP regulatory mandates.

Design an incident response readiness plan for OT networks by establishing safety-first detection workflows and controlled active monitoring techniques. This approach prioritizes operational continuity while mapping threats to industrial control system vulnerabilities and ISA/IEC 62443 compliance targets.

Passive monitoring works for asset discovery across industrial control system zones, but combining it with controlled active techniques ensures comprehensive inventory. This dual approach captures deep Purdue level device data without disrupting critical manufacturing or energy operations.

Automated NERC CIP compliance mapping limitations include relying on accurate asset visibility and requiring manual validation of ESP/CIP control deviations. While automation accelerates gap analysis across OT networks, human verification remains necessary for complex industrial control system segmentation boundaries.
