Secure Spring Boot API endpoints by applying deny-by-default access control, method-level role checks, safe token handling, and secure login flows. This hardening ensures protected endpoints validate user identities and enforce authorization before granting access.

The safest way to handle secrets in Spring Boot is through externalized secrets management, safe token handling, and improved password storage. This prevents exposed secrets and ensures sensitive credentials are protected in production environments.

Configure CSRF, CORS, and security headers in Spring Boot by applying correct browser security settings and validated DTOs. This reduces injection risk, prevents cross-site request forgery, and enforces proper cross-origin resource sharing policies.

Yes, you can harden Spring Boot services for production by applying rate limiting, CVE-aware dependency hygiene, and sensitive-data logging practices. These operational hardening techniques protect APIs from abuse and maintain dependency security.

The best way to review a Spring Boot admin API is to identify missing guards, validate DTOs, and recommend safer defaults before release. This security review checks endpoints for authentication, authorization, and input validation weaknesses.
