Security headers and request logging

Add middleware to set HSTS, X-Content-Type-Options, and secure cookies; log JSON with actor and trace_id for auth and admin routes.

Why this matters

Hardening and auditing align with SOC 2 security criteria.

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

Avoid

handler = (req) => Response.ok('ok');

Prefer

final handler = const Pipeline().addMiddleware(securityHeaders()).addMiddleware(auditLogs()).addHandler(app);

Good

response.change(headers:{'Strict-Transport-Security':'max-age=31536000'})

Bad

response.change(headers:{})

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.
