CMMC Level 2 requires that wireless access be formally authorized based on management-approved policy and criteria. The Assessment Guide specifies that “management guidelines form the basis for the requirements that must be met prior to authorizing a wireless connection.” Therefore, a written policy executed by the CEO, which defines pre-authorization requirements, constitutes proper evidence of authorization. Informal emails or IT connection instructions do not meet this requirement.

Exact extracts:

“Authorize wireless access prior to allowing such connections.”

“Assessment Objectives … Determine if: [a] wireless access points are identified; and [b] wireless access is authorized prior to allowing such connections.”

“Guidelines from management form the basis for the requirements that must be met prior to authorizing a wireless connection. These guidelines may include the following: • types of devices, such as corporate or privately owned equipment; • configuration requirements of the devices; and • authorization requirements before granting such connections.”

Assessment method – Examine: “Access control policy; procedures addressing wireless implementation and usage (including restrictions); wireless access authorizations …”

Why the other options are unacceptable:

A and C are ad-hoc instructions from the CEO, not a formal management policy establishing authorization criteria.

D is an IT-authored instruction document, not a management-level authorization policy.
