## What it is
Spring Security is a powerful and highly customizable authentication and access-control framework for Java applications, and the de-facto standard for securing Spring-based apps. It provides comprehensive, extensible support for authentication and authorization, plus protection against common attacks like CSRF, session fixation, and clickjacking.

## Use cases
- add login and authentication to a Spring Boot application
- secure REST API endpoints with role-based access control
- protect a web app against CSRF and session fixation attacks
- integrate OAuth2 or JWT-based authentication in Java
- secure reactive WebFlux applications
- customize user authentication with a custom UserDetailsService
- add a default login page and generated credentials to a Spring Boot app

## When to choose
- you are building a Spring or Spring Boot application and need authentication and authorization
- you want battle-tested protection against common web vulnerabilities out of the box
- you need fine-grained, extensible security configuration for servlet or reactive apps
- you want the de-facto standard Java security framework with long-term community and enterprise support

## When to avoid
- your project does not use the Spring ecosystem, where lighter-weight alternatives may fit better
- you need a standalone identity provider or SSO server rather than an in-application security layer
- you want a zero-configuration security solution without learning Spring's configuration model
