Java full stack applications ensure security through a layered approach that protects both the frontend and backend components. Key strategies include:

1. Authentication & Authorization:
   Use frameworks like Spring Security for managing user authentication (login) and authorization (access control). Integrate OAuth2, JWT, or SAML for secure and scalable identity management.

2. Input Validation & Sanitization:
   Validate all user inputs on both frontend and backend to prevent injection attacks (e.g., SQL injection, XSS). Use libraries like Hibernate Validator (JSR 380) for backend validation.

3. Secure Communication:
   Enforce HTTPS to encrypt data in transit. Use TLS certificates to secure API and web traffic.

4. SQL Injection Protection:
   Use ORMs like Hibernate or prepared statements (JDBC) to safely handle database queries.

5. Cross-Site Scripting (XSS) & CSRF Protection:
   Escape output in web views (JSP, Thymeleaf, React). Use CSRF tokens with forms, which Spring Security provides out of the box.

6. Session Management:
   Secure sessions with proper timeouts, cookie flags (HttpOnly, Secure), and regeneration on login/logout.

7. Security Headers:
   Set HTTP headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate browser-based threats.

8. Dependency Management:
   Regularly scan and update dependencies using tools like OWASP Dependency-Check or Maven plugins to prevent known vulnerabilities.

9. Logging & Monitoring:
   Implement logging and alerting (e.g., using ELK stack or Splunk) to detect suspicious activities.

10. Secure Deployment:
    Harden servers, restrict access, and use firewalls and reverse proxies for added protection.

Combining these practices helps ensure robust, end-to-end security in Java full stack applications.
