: All attempts to use the key for encryption or decryption are logged in AWS CloudTrail , providing an independent audit trail of who accessed the code and when. How it Works The process typically follows an envelope encryption model: : Using a CMK allows organizations to satisfy

: If a customer disables or deletes the CMK, Lambda can no longer access the .zip artifacts, effectively revoking access to the function code immediately.
