What this requirement asks
Control connection of mobile devices.
This is a CMMC Level 2 requirement in the Access Control family, drawn from NIST SP 800-171 Rev. 2. An assessor evaluates it objective by objective — every objective below must be supported by evidence, not just described in a policy.
