Introduction
Production-grade security is layered. The cheap, high-impact list every Spring Boot app should ship.
Understanding the topic
The non-negotiable checklist:
- ✅ HTTPS everywhere; HSTS preload.
- ✅ Dependency scanning (Dependabot, Snyk) on every PR.
- ✅ Secrets in a vault, never in env files in git.
- ✅ Rotate keys/passwords on a schedule.
- ✅ Run as non-root in containers; read-only FS where possible.
- ✅ Image scanning (Trivy) in CI.
- ✅ WAF in front; rate limit at gateway.
- ✅ Audit log for sensitive ops (login, admin actions, money).
- ✅ Separate IAM roles per service; least privilege.
