It processes HTTP requests through a series of security filters.
The Spring Security Filter Chain acts like a security gatekeeper. It intercepts HTTP requests before they reach business logic, processing them through filters like CORS, CSRF, and Authentication. This ensures that requests are vetted for origin, valid tokens, and credentials. For example, in an e-commerce app, the chain will block unauthorized access to user data.
