Episode 50 — Key Management & BYOK/KMS Rotations
Key management underpins encryption controls within the Confidentiality and Privacy criteria. The exam expects understanding of lifecycle governance—key generation, storage, distribution, rotation, and destruction. Bring Your Own Key (BYOK) models let customers retain control of cryptographic keys within cloud Key Management Services (KMS). Proper configuration ensures data remains encrypted even from provider administrators. Rotations verify that keys are periodically refreshed and obsolete keys revoked, maintaining cryptographic strength and limiting potential exposure. Poor key hygiene can invalidate otherwise strong encryption practices.
Operationally, organizations use centralized KMS solutions that integrate with identity and access controls to enforce least privilege. Documented procedures define rotation intervals, dual-control approvals for key operations, and logging of every cryptographic event. Evidence includes rotation logs, policy references, and access reviews for key custodians. Automated rotation with verification scripts reduces error and audit effort. For exam purposes, remember that key management bridges technology and governance—security rests as much on policy enforcement and separation of duties as on encryption algorithms.
