CSA CCM v4.1 · CEK - Cryptography, Encryption & Key Management

CEK-17 Key Deactivation

Processes, procedures and technical measures are defined, implemented and evaluated to deactivate keys when they reach their expiry date, taking legal and regulatory requirements into account.

Source: CSA CCM v4.1, CEK-17. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open CSA CCM v4.1 in the compliance library.

Version 4.1 adds 11 controls (among them API security, log sanitisation and a service bill of materials) and renumbers several domains. CSA accepts v4.0.x during its transition; if your STAR assessment is still on v4.0.1, check the numbering against it.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.
