Mapped to NIST 800-171 Requirement: 3.6.1
CMMC Assessment Objective: IR.L2-3.6.1[f]
What This Objective Means
Beyond scheduled reviews and maintenance, this control focuses on responsive updates—making sure your IR plan evolves based on what’s happening in your environment.
Typical triggers for updates include:
• Lessons learned from actual incidents or exercises
• Changes in system architecture or infrastructure
• Staff turnover affecting IR roles or contacts
• Adoption of new tools (e.g., new SIEM or EDR)
• Changes in legal or regulatory reporting requirements (e.g., DFARS, NIST)
Why It Matters
If your plan doesn’t reflect your real-world environment:
• You may follow outdated procedures during a critical incident
• Communication paths may fail due to old contact info
• Important systems or tools may be left out of response actions
• You could miss required reporting deadlines or breach containment steps
This control ensures your IR plan is a living document, not a static one.
How to Implement It
1. Define What Triggers an Update
• Examples:
◦ Completion of a major incident
◦ Internal audit or tabletop exercise
◦ Technology changes
◦ Staff or team restructuring
◦ New compliance obligations
2. Establish a Change Control Process
• Route changes through your compliance or IT governance process
• Require approval, documentation, and version control
3. Communicate Changes
• Notify IR team members of updates
• Include updated documents in training, onboarding, and awareness
4. Track Version History
• Record:
◦ Change date
◦ Summary of changes
◦ Reviewer/approver info
◦ New version number
5. Update Supporting Documentation
• Ticketing workflows, escalation procedures, tool configurations, and call trees should be refreshed too
Evidence the Assessor Will Look For
• Updated IR documentation with change history
• Notes or reports from incidents or exercises that led to plan changes
• Sign-offs or approvals for new versions
• Communication records showing updates were shared with staff
• Comparison of current tech stack and IR documentation alignment
Common Gaps
• Plan reviewed, but not updated after real-world changes
• IR documentation references legacy tools or contacts
• Staff unaware of revised roles or workflows
• No documented version control or change log
