1 point deducted from 110 when not implemented.
CMMC level

Level 2 only; not among the 17 Level 1 practices.

From NIST SP 800-171A, each one a “determine if” an assessor answers.

What an assessor checks

NIST SP 800-171A breaks 3.13.13 into 2 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.

  1. [a]Determine if use of mobile code is controlled.
  2. [b]Determine if use of mobile code is monitored.
Examine
[SELECT FROM: System and communications protection policy; procedures addressing mobile code; mobile code usage restrictions, mobile code implementation policy and procedures; security plan; list of acceptable mobile code and mobile code technologies; list of unacceptable mobile code and mobile technologies; authorization records; system monitoring records; system audit logs and records; other relevant documents or records].
Interview
[SELECT FROM: System or network administrators; personnel with information security responsibilities; personnel with responsibilities for managing mobile code].
Test
[SELECT FROM: Organizational process for controlling, authorizing, monitoring, and restricting mobile code; mechanisms supporting or implementing the management of mobile code; mechanisms supporting or implementing the monitoring of mobile code].

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.
