Encrypt secrets at rest with KMS client

Use a KMS client to derive DEKs and encrypt sensitive blobs; rotate CMKs annually and re-encrypt on rotation.

Why this matters

Managed key lifecycles meet SOC 2 encryption expectations.

Side-by-side examples engineers can pattern-match during review.

Avoid

val secret = plain.toByteArray(); store(secret)

Prefer

val ct = kms.encrypt(deriveDek(), plain); store(ct)

Good

kms.encrypt(key, data)

Bad

store(data)

From the same buckets as this rule.

Critical
Encrypt sensitive data at rest with KMS and rotate keys
Use envelope encryption (AES-256-GCM) with cloud KMS-managed CMKs for databases, object storage, and backups. Rotate CMKs at least annually and rotate DEKs per object/file.

Critical
Enforce TLS 1.2+ and HSTS on all external endpoints
Public services must require TLSv1.2 or higher and set HSTS (max-age ≥ 15552000, includeSubDomains). Reject plaintext HTTP and weak ciphers; cookies must be Secure and HttpOnly with SameSite set.

Critical
Use a secrets manager and 90-day rotation policy
All credentials (API keys, DB passwords, tokens) must be stored in a secrets manager with automatic rotation ≤ 90 days; forbid hardcoded or .env-committed secrets via CI checks.
