Redact PII with log wrappers

Wrap logger to filter emails and tokens using regex before logging; include trace_id in every entry.

Why this matters

Prevents leakage of sensitive data and improves audit quality for SOC 2.

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

Avoid

log.Printf("login %s token=%s", email, token)

Prefer

logger.Info("auth.login", zap.String("email_hash", hash(email)), zap.String("trace_id", tid))

Good

logger.Info("export", zap.String("trace_id", tid))

Bad

log.Println(email)

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.
