An OSC is presenting evidence of its fulfillment of CM.

Applicable Requirement: CM.L2-3.4.1 — “Establish and maintain baseline configurations and inventories of organizational systems (including hardware, software, firmware, and documentation) throughout the respective system development life cycles.”

Why C is Correct: Baseline management requires documenting and tracking authorized deviations to ensure systems remain consistent with approved baselines. Evidence must show the OSC manages exceptions as part of its configuration management process.

Why Other Options Are Insufficient:

A: Physical safeguards protect images but do not demonstrate baseline management.

B: Reviews may be helpful, but deviations are explicitly required documentation.

D: Chain of custody applies to asset tracking, not baseline management.
