Episode 32 — Secure Key Management and KMS

Key management underpins all cryptographic operations, and FedRAMP reviewers expect a clear, auditable key lifecycle. This episode defines the phases of key management: generation, distribution, storage, use, rotation, archival, and destruction. We connect these stages to requirements within NIST SP 800-57 and the FedRAMP baselines, emphasizing roles and segregation of duties among key custodians, system administrators, and automated services. You will learn to document whether keys are customer-managed, provider-managed, or jointly controlled, and to record where key material resides—software modules, hardware security modules, or cloud key management services. Assessors will expect certificate numbers for FIPS-validated modules and records of secure key rotation that include timestamps and authorization details.

We then focus on operational assurance. Examples show how to enforce strict access permissions through IAM policies, ensure encryption contexts are tenant-specific, and automate key rotation to meet defined intervals. We discuss backup encryption, handling of master keys for derived data keys, and integrating customer-supplied key (CSK) or bring-your-own-key (BYOK) options without exposing provider management planes. Documentation should describe revocation procedures, disaster recovery for key stores, and audit log retention that proves each key event occurred as stated. Common pitfalls include undocumented replication of key stores across regions or inconsistent revocation between services. Strong key management provides confidence that encryption integrity cannot be undermined by administrative error or overlooked processes.
