What an assessor checks
NIST SP 800-171A breaks 3.4.3 into 4 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- [a]Determine if changes to the system are tracked.
- [b]Determine if changes to the system are reviewed.
- [c]Determine if changes to the system are approved or disapproved.
- [d]Determine if changes to the system are logged.
- Examine
- [SELECT FROM: Configuration management policy; procedures addressing system configuration change control; configuration management plan; system architecture and configuration documentation; security plan; change control records; system audit logs and records; change control audit and review reports; agenda/minutes from configuration change control oversight meetings; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with configuration change control responsibilities; personnel with information security responsibilities; system or network administrators; members of change control board or similar].
- Test
- [SELECT FROM: Organizational processes for configuration change control; mechanisms that implement configuration change control].
If it is open: POA&M eligibility
May be carried on a Level 2 POA&M · 1 point deducted
A 1-point requirement outside the six named exclusions - eligible to carry, and NOT MET until a closeout assessment confirms it.
A POA&M is only permitted at a score of 88 or above, and closes in one 180-day window. Check a full gap list or compute your score.
