implementing-patch-management-for-ot-systems
This skill covers implementing a structured patch management program for OT/ICS environments where traditional IT patching approaches can cause process disruption or safety hazards. It addresses vendor compatibility testing, risk-based patch prioritization, staged deployment through test environments, maintenance window coordination, rollback procedures, and compensating controls when patches cannot be applied due to operational constraints or vendor restrictions.

# Implementing Patch Management for OT Systems
## When to Use
- When establishing a formal OT patch management program for the first time
- When responding to critical ICS-CERT advisories affecting deployed OT systems
- When preparing for NERC CIP-007-6 or IEC 62443 patch management compliance audits
- When planning patch deployment during limited maintenance windows in continuous operations
- When evaluating compensating controls for systems that cannot be patched
**Do not use** for IT-only patch management without OT considerations, for emergency patching during active cyber incidents (see performing-ot-incident-response), or for firmware upgrades that change PLC functionality (requires separate change management).
