Assessment objectives
From NIST SP 800-171A · 2 objectives must be met to satisfy this control
Examine
[SELECT FROM: Continuous monitoring strategy; system and information integrity policy; procedures addressing system monitoring tools and techniques; facility diagram/layout; security plan; system design documentation; system monitoring tools and techniques documentation; locations within system where monitoring devices are deployed; system configuration settings and associated documentation; 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 monitoring the system].
Test
[SELECT FROM: Organizational processes for system monitoring; mechanisms supporting or implementing system monitoring capability].

What we look for in practice
The following are placeholder notes that should be refined based on practice experience.
What assessors look for in practice. Documented evidence that this control is implemented across all CUI-handling systems within scope. Specific artifacts vary, but expect requests for written procedures, system configurations, and operational records demonstrating the control is active.
Common failure patterns. Typical issues include incomplete documentation, inconsistent implementation across systems, and missing periodic review records. Refine this section as your practice accumulates direct assessment experience.
Strong evidence looks like. Formal policy referencing this control, technical configurations demonstrating enforcement, periodic review logs with sign-off, and procedures for handling exceptions.
Scoring and POA&M context. 3-point control under the DoD Assessment Methodology. Meaningful but more contained scoring impact. Not POA&M-eligible — must be implemented at assessment time.
