Spring Security is a powerful and flexible authentication and authorization framework for Java-based applications. It provides comprehensive security services such as authentication, access control, encryption, and session management.

Key Features 📌

  • Authentication: Supports form-based, API key, OAuth2, and JWT authentication
  • Authorization: Enables role-based access control (RBAC) and method-level security
  • Security Configuration: Customizable via Java config or XML
  • Integration: Works seamlessly with Spring Framework and Spring Boot

Use Cases 🌐

  • Securing REST APIs with @PreAuthorize annotations
  • Implementing OAuth2 client and resource server patterns
  • Adding CSRF protection and secure cookie handling
  • Managing password policies and encryption standards

Best Practices 🛡️

  1. Always use HTTPS for production environments
  2. Regularly update dependencies to patch vulnerabilities
  3. Implement role hierarchy for better access control
  4. Enable logging for security events
