Devise + MFA for privileged actions

Require TOTP or WebAuthn MFA for admin areas; verify mfa_verified_at timestamp before sensitive routes.

Why this matters

Step-up authentication supports SOC 2 access control.

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

Avoid

before_action :require_admin

Prefer

before_action :require_admin; before_action :require_fresh_mfa, only: [:export, :rotate_keys]

Good

session[:mfa_verified_at] = Time.now

Bad

session[:mfa_verified_at] = nil

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.
