Configure JWT authentication in Spring Boot by prioritizing stateless JWTs or opaque tokens with revocation lists. This approach ensures robust API security by validating tokens externally and managing secure keys properly across microservices and monoliths.

Enable method-level authorization in Spring Security using @EnableMethodSecurity. Apply @PreAuthorize annotations to enforce granular access control directly within your Spring Boot services, securing endpoints based on user roles and permissions across microservices and monoliths.

The best way to secure cookies in Spring Boot is configuring them with httpOnly, Secure, and SameSite=Strict attributes. This combination protects session tokens from cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks effectively.

Yes, Spring Security works for both microservices and monolith architectures. You can enforce robust authentication, token validation, and CSRF protection consistently across distributed services or single monolithic Spring Boot applications using centralized configuration.

Externalize secret keys for Spring Boot microservices by moving them out of source code into environment variables or secure vaults. This practice prevents credential leakage and ensures proper token validation and key management across your distributed deployment.

You need CSRF protection for stateless APIs to prevent cross-site request forgery vulnerabilities. Even with token validation, applying CSRF protection alongside secure headers defends against session hijacking and ensures robust API security across microservices.
