What is Spring Security Filter Chain?

1.	What is Spring Security Filter Chain?
Answer» Spring Security executes most of its security features using the filter chain. Spring security is driven through SERVLET filters in web applications. A servlet filter intercepts requests before they REACH the PROTECTED resource (e.g., a Spring controller). As a result, every request for a protected resource will be processed through a spring security filter chain for completing authentication and AUTHORIZATION PURPOSES.
