3.14.6 Monitor systems and communications

Monitor organizational systems, including inbound and outbound communications traffic, to detect attacks and indicators of potential attacks.

SPRS weight: 5; 5 points deducted from 110 when not implemented.
CMMC level: L2; Level 2 only; not among the 17 Level 1 practices.
Assessment objectives: 3; From NIST SP 800-171A, each one a “determine if” an assessor answers.

What an assessor checks

NIST SP 800-171A breaks 3.14.6 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 system is monitored to detect attacks and indicators of potential attacks.
[b]Determine if inbound communications traffic is monitored to detect attacks and indicators of potential attacks.
[c]Determine if outbound communications traffic is monitored to detect attacks and indicators of potential attacks.

Examine: [SELECT FROM: System and information integrity policy; procedures addressing system monitoring tools and techniques; continuous monitoring strategy; system and information integrity policy; procedures addressing system monitoring tools and techniques; facility diagram or layout; security plan; system design documentation; system monitoring tools and techniques documentation; locations within system where monitoring devices are deployed; system protocols; system configuration settings and associated documentation; 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 monitoring the system; personnel with responsibility for the intrusion detection system].
Test: [SELECT FROM: Organizational processes for system monitoring; mechanisms supporting or implementing intrusion detection capability and system monitoring; mechanisms supporting or implementing system monitoring capability; organizational processes for intrusion detection and system monitoring; mechanisms supporting or implementing the monitoring of inbound and outbound communications traffic].

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.

No direct mapping.
