What is the purpose of a SecurityFilterChain in Spring Boot?

A SecurityFilterChain defines the order and rules for security filters that process HTTP requests. It controls how requests are authenticated and authorized before reaching the application.

How do you create a SecurityFilterChain bean in Spring Boot?

You create a SecurityFilterChain bean by defining a method annotated with @Bean that returns a SecurityFilterChain object, usually built using HttpSecurity to configure security rules.

What does the method http.authorizeHttpRequests() configure in SecurityFilterChain?

It configures which HTTP requests require authentication or specific roles and which are allowed without authentication.

intermediate

Why is the order of filters important in a SecurityFilterChain?

The order determines how requests are processed. Filters earlier in the chain can block or modify requests before later filters see them, affecting security behavior.

intermediate

What is the role of http.csrf().disable() in SecurityFilterChain configuration?

It disables Cross-Site Request Forgery protection, which might be needed for APIs or non-browser clients but should be used carefully to avoid security risks.

Which annotation is used to define a SecurityFilterChain bean in Spring Boot?

A @Component

B @Controller

C @Service

D @Bean

The @Bean annotation marks a method that returns a bean managed by Spring, such as SecurityFilterChain.

What does http.authorizeHttpRequests().anyRequest().authenticated() do?

A Allows all requests without authentication

B Blocks all requests

C Requires authentication for every request

D Only allows GET requests

This configuration requires every HTTP request to be authenticated.

Why might you disable CSRF protection in SecurityFilterChain?

A To improve performance

B For APIs that do not use cookies

C To allow all users access

D To enable HTTPS

CSRF protection is mainly for browser clients using cookies; APIs without cookies often disable it.

What is the effect of filter order in SecurityFilterChain?

A Filters run in the order defined, affecting request processing

B No effect, filters run in parallel

C Filters run randomly

D Filters only run if previous filters fail

Filters run in the order they are defined, so order affects how requests are handled.

Which method is used to start configuring HTTP security in SecurityFilterChain?

A http.authorizeHttpRequests()

B http.configure()

C http.build()

D http.start()

http.authorizeHttpRequests() begins the configuration of request authorization rules.

Explain how to configure a SecurityFilterChain bean to require authentication for all requests except for a public home page.

Think about using permitAll() for the home page and authenticated() for others.

Describe why filter order matters in SecurityFilterChain and give an example of a filter that should run early.

Consider what happens if authentication runs after authorization.
