Begin with authorization, not a screenshot collection
Access control evidence should connect an approved need with an implemented permission and an operating review process. For Level 2, the NIST SP 800-171 Revision 2 Access Control family addresses authorized users, processes, devices, permitted functions, and additional safeguards. Read the applicable objectives before collecting artifacts. A list of current accounts may show who exists, but it rarely explains who approved access, what those users can do, or whether the permissions remain appropriate. Build the evidence around those questions and the actual assessment scope, including the systems operated by providers.
Show the relationship between roles and permissions
Prepare a clear description of business roles, protected resources, and the permissions associated with each role. Identify privileged functions separately from ordinary work. Support the description with configuration exports or demonstrations that show how the rules are enforced. If permissions are inherited through groups, explain the chain so an assessor does not have to guess why an account can reach a resource. Remove unnecessary personal details from working examples where appropriate, while preserving the information an authorized assessment actually needs. Avoid claiming a single directory screenshot proves permissions in every application and local device.
Follow one account through its life cycle
Choose a suitable account example and trace the request, authorization, provisioning, relevant changes, and eventual removal or review. This is a practical internal quality check, not a prescribed universal assessment sample. Compare dates and system identifiers across the records. If the approval names one role while the deployed account has broader rights, resolve the mismatch. Include temporary accounts, vendor support, and transfers between jobs in the process design. An account can remain active for legitimate reasons, but those reasons and its authorized privileges should be explainable through the operating procedures used by the organization.
Demonstrate privileged and remote access carefully
Identify which accounts perform administration, how their use is authorized, and what technical restrictions apply. For remote access, connect the documented method with the actual service configuration and relevant user or device permissions. Evaluate related identification, authentication, logging, and session controls against their own requirements rather than assuming access control evidence proves them all. Use planned demonstrations and redacted captures when appropriate. Do not place active passwords, recovery codes, private keys, or unrestricted administrative access links into an evidence folder. The aim is to show the control without creating a new exposure.
Make evidence gaps actionable
Look for orphaned accounts, unexplained privileged membership, stale approvals, unmanaged service identities, and provider accounts whose ownership is unclear. These are review questions, not automatic findings in every environment. Assign the person who can verify each issue and define what record or technical change will close it. NIST SP 800-171A describes examination, interviews, and testing as assessment methods; a document set should support the relevant objectives rather than replace operational review. A clean index cannot repair an authorization process that nobody follows, so test the underlying workflow before marking the evidence ready.
Keep a current, controlled evidence set
Record the capture date, source system, requirement mapping, owner, and explanation for each artifact. Protect identity information and architecture details under the approved handling rules of the organization. When an access process or identity service changes, update the implementation statement and affected evidence together. CMMC Pulsar publicly describes organizing artifacts alongside controls and assembling documentation exports; evaluate whether that workflow preserves the context your reviewers need. The technical owner must validate the content regardless of storage tool. Preparing an access evidence set supports assessment, while official CMMC status still follows the required assessment and affirmation process.
