What an assessor checks
NIST SP 800-171A breaks 3.14.4 into 1 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.
- Determine if malicious code protection mechanisms are updated when new releases are available.
- Examine
- [SELECT FROM: System and information integrity policy; configuration management policy and procedures; procedures addressing malicious code protection; malicious code protection mechanisms; records of malicious code protection updates; security plan; system design documentation; system configuration settings and associated documentation; scan results from malicious code protection mechanisms; record of actions initiated by malicious code protection mechanisms in response to malicious code detection; system audit logs and records; other relevant documents or records].
- Interview
- [SELECT FROM: System or network administrators; personnel with information security responsibilities; personnel installing, configuring, and maintaining the system; personnel with responsibility for malicious code protection; personnel with configuration management responsibility].
- Test
- [SELECT FROM: Organizational processes for employing, updating, and configuring malicious code protection mechanisms; organizational process for addressing false positives and resulting potential impact; mechanisms supporting or implementing malicious code protection mechanisms (including updates and configurations); mechanisms supporting or implementing malicious code scanning and subsequent actions].
If it is open: POA&M eligibility
Not POA&M-eligible: above the 1-point ceiling · 5 points deducted
Worth 5 points. No requirement over 1 point may appear on a Level 2 POA&M, so this has to be closed before the assessment.
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.
