NIST CSF PR.IP-3: Configuration Change Control
Configuration change control is your safeguard against unauthorized or poorly documented system modifications that introduce security gaps. PR.IP-3 requires formal processes to review, approve, and document every change to your infrastructure. For SMBs managing lean teams, establishing these controls doesn't mean bureaucracy—it means visibility and risk reduction.
What this means
Configuration change control ensures that modifications to systems, applications, and infrastructure are tracked, approved, and tested before deployment. This control prevents accidental misconfigurations, reduces the attack surface from unauthorized changes, and maintains an auditable record of who changed what, when, and why. It applies across development, staging, and production environments.
How to comply
- 1.Document a formal change control policy that defines the review and approval process for all configuration changes
- 2.Establish a change advisory board (CAB) or designate change approvers with clear authority and responsibilities
- 3.Implement a change request process requiring business justification, risk assessment, and rollback plan before approval
- 4.Test configuration changes in a staging environment that mirrors production before deploying to live systems
- 5.Maintain a change log or configuration management database (CMDB) recording all changes, approvers, dates, and outcomes
- 6.Define emergency change procedures for critical security patches with post-implementation review within 24-48 hours
- 7.Automate baseline configuration checks to detect and alert on unauthorized or drift changes
- 8.Schedule regular configuration audits to compare live systems against approved baselines
Evidence auditors look for
- Change control policy document signed and dated by management
- Change request tickets showing approval workflow and audit trail
- Configuration baseline documents and version control history
- Change log entries with timestamps, change descriptions, approvers, and results
- Test plan and test results from pre-production environment
- Emergency change procedures and post-implementation review records
- Automated configuration scanning reports showing compliance and drift detection
- Meeting minutes from change advisory board reviews
