Data retention job with classification

Run a scheduled job that deletes telemetry after 30 days and anonymizes PII after the retention window; log deletions with data_class and count.

Why this matters

Enforces data lifecycle controls required by SOC 2.

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

Avoid

cron(' * * * ', ()=> / no-op */ )

Prefer

cron('0 3 * * ', ()=> purge({ data_class:'telemetry', olderThanDays:30 }))

Good

purge({ data_class:'telemetry' })

Bad

db.deleteAll()

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.
