What problem does it solve?
This guide helps developers close common security gaps in Java Spring Boot services by providing actionable patterns, configuration advice, and a release checklist to prevent authentication flaws, injection risks, misconfigured headers, exposed secrets, and insufficient rate limiting.
Core Features & Use Cases
- Authentication & Token Handling: guidance for stateless JWTs, opaque tokens, and secure session cookies.
- Authorization: method-level guards, role checks, and default-deny principles.
- Input Validation & Injection Prevention: use Bean Validation, custom validators, and parameterized queries to avoid SQL injection.
- Secrets & Key Management: externalize credentials to environment variables or Vault and rotate secrets regularly.
- Infrastructure Protections: configure secure headers, CORS at the filter level, CSRF rules appropriate to the client type, rate limiting, file upload validation, and CI dependency scanning for CVEs.
- Use Case: secure an account management API that requires role-based access, protects sensitive payloads, and enforces rate limits on authentication endpoints.
Quick Start
Configure Spring Security for stateless JWT validation, enable method-level authorization, externalize secrets to Vault or environment variables, and run dependency scanning in CI before release.
