Commission audit and assurance assessments from assessors independent of the activity being examined, run them against recognised standards, and repeat them at least annually.
This control maps to 56 controls across 33 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
NIST-CSF-ID.IM-02 Improvements are identified from security tests and exercises, including those done in coordination with suppliers and relevant third parties
NIST-CSF-ID.RA-09 The authenticity and integrity of hardware and software are assessed prior to acquisition and use
You are reading one control. How much of Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 have you already done?
Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 CCM-A&A-02 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 140 of 197 Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 12 were rejected on the NIST SP 800-53 Rev 5 pair alone.
