How does Symfony's security system work?

Symfony's security system provides tools for authentication and authorization in your application. It is highly configurable and integrates seamlessly with various authentication providers.

To use Symfony security:

1. Configure the security settings in config/packages/security.yaml.
2. Define user roles and access control for different routes.
3. Create a login form or use a firewall for authentication.

Example of a security configuration:

security:\n    firewalls:\n        main:\n            anonymous: true\n            form_login:\n                login_path: login\n                check_path: login_check
