Spring Security Project Modules

Spring Security is organized into various modules that offer different functionalities for implementing security in Spring applications. Each module focuses on specific aspects of security. As of my last knowledge update in September 2021, here are some of the core modules provided by Spring Security:

1. spring-security-core:
   This module provides the fundamental building blocks for authentication, authorization, and other core security features. It includes configuration classes, user details services, and interfaces for authentication providers.
2. spring-security-config:
   This module offers configuration classes for setting up Spring Security features using Java configuration.
3. spring-security-web:
   The web module includes components and filters for securing web applications. It includes classes for handling HTTP-specific security concerns such as login forms, filters, and request/response handling.
4. spring-security-taglibs:
   This module provides JSP tag libraries that can be used to apply security constraints directly in JSP pages.
5. spring-security-ldap:
   This module provides integration with LDAP (Lightweight Directory Access Protocol) for user authentication and authorization.
6. spring-security-oauth2:
   The OAuth2 module provides support for implementing OAuth2 authentication and authorization in Spring applications.
7. spring-security-cas:
   This module supports integration with the CAS (Central Authentication Service) single sign-on protocol.
8. spring-security-openid:
   It offers OpenID authentication and authorization support for Spring applications.
9. spring-security-saml2-core:
   This module provides support for SAML 2.0 (Security Assertion Markup Language) authentication and authorization.
10. spring-security-test:
    This module includes testing utilities and classes for writing unit and integration tests for Spring Security components.
11. spring-security-jwt:
    A module that supports JSON Web Token (JWT) authentication and authorization.

These modules can be combined based on your project’s needs. Depending on your application type (web, REST API, etc.) and the security requirements, you can include the relevant modules to configure Spring Security appropriately. Keep in mind that Spring Security is modular, and new modules or enhancements might have been introduced after my last update in September 2021. Always refer to the latest official Spring Security documentation for the most up-to-date information on modules and features.
