Episode 30 — Enforce FIPS-Validated Cryptography

FedRAMP requires cryptography that is validated under the Federal Information Processing Standards (FIPS) program, so you must demonstrate that every cryptographic function protecting federal data uses a validated module configured in an approved mode. This episode clarifies what “FIPS-validated” actually means, how to identify the cryptographic module boundary, and how to record certificate numbers, versions, and operational modes in the SSP. We explain how to select approved algorithms and modes (e.g., AES-GCM, SHA-2, TLS 1.2+ with strong ciphers), document key strengths, and manage random number generation requirements. We also connect crypto design to identity and data flow choices—what is encrypted at rest and in transit, where termination occurs, how keys are generated and rotated, and how you segregate customer keys in multi-tenant environments.

Operationalizing validated cryptography requires disciplined configuration and evidence. We cover using platform key management services (KMS) with proof of FIPS mode, validating OpenSSL or OS crypto libraries in FIPS-capable builds, and documenting hardware security module usage when applicable. Examples show how to present cipher suite policies, certificate pinning or validation behaviors, and logs proving key rotation and certificate renewal. We highlight pitfalls that generate findings—mixing validated and non-validated paths, relying on default libraries that fall out of FIPS mode, or neglecting to update certificates across disaster recovery regions. During continuous monitoring, include checks that detect weak ciphers, expired certs, and non-FIPS modules in new components. With verifiable configurations and clear traceability to certificates, your cryptography posture becomes auditable, resilient, and compliant.
