What an assessor checks
NIST SP 800-171A breaks 3.1.4 into 3 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- [a]Determine if the duties of individuals requiring separation to reduce the risk of malevolent activity are defined.
- [b]Determine if organization-defined duties of individuals requiring separation are separated.
- [c]Determine if separate accounts for individuals whose duties and accesses must be separated to reduce the risk of malevolent activity or collusion are established
- Examine
- [SELECT FROM: Access control policy; procedures addressing divisions of responsibility and separation of duties; security plan; system configuration settings and associated documentation; list of divisions of responsibility and separation of duties; system access authorizations; system audit logs and records; other relevant documents or records].
- Interview
- [SELECT FROM: Personnel with responsibilities for defining divisions of responsibility and separation of duties; personnel with information security responsibilities; system or network administrators].
- Test
- [SELECT FROM: Mechanisms implementing separation of duties policy].
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.
