The two most prominent features offered by Spring Security are authentication and authorization. These features play a crucial role in ensuring the security of an application. However, Spring Security goes beyond authentication and authorization and offers additional capabilities to protect against exploits and integrate with other frameworks.
When it comes to Spring Security, several core components play a vital role in providing security features for Java applications. These components work together to ensure robust authentication, authorization, and other security functionalities.
At a high level, Spring Securityhandles user authentication through a series of steps. Most steps are common for all kinds of authentications, yet few authentication flows require specific steps. The following steps demonstrate the form-login-based authentication where the user inputs the username/password combination in the request. 1. The user at...
At a high level, Spring Security handles user authorization through a process that involves several components working together. Here’s an overview of the process. 1. Once the request is authenticated, it proceeds to the authorization phase. The FilterChainProxyinvokes the appropriate authorization filter in the filter chain. 2. The AuthorizationFi...
The PasswordEncoder is an interface used for encoding and verifying passwords using methods encode() & matches(). It is responsible for taking a user’s password, applying a one-way hashing algorithm, and securely storing the hashed password. When a user attempts to log in, the entered password is again hashed using the same algorithm, and the gener...
When it comes to enabling Spring Security in a non-Spring Boot application, there are a few approaches we can take. Let’s explore two standard methods: 1. Java-based configuration 2. XML-based configuration
If we are using Spring Boot, enabling Spring Security is quite straightforward. All we need to do is add the Spring Security starter to our project’s dependencies, and the auto-configuration will be available by default. This is because when Spring Security is in the classpath, the WebSecurityEnablerConfiguration automatically activates the @Enable...
The @EnableWebSecurityannotation is used to enable the web security of an application. When this annotation is added to a configuration class, it indicates that the class will provide the necessary configurations and settings for securing the web application. In a non-Spring boot application, the @EnableWebSecurityannotation performs the following ...
In Spring Security, both roles and authorities are used to define and manage user permissions. However, there is a subtle difference between the two: 1. Role: A role represents a broad category or group of permissions. It is typically used to group related authorities together. Roles can be assigned to users, and users can have multiple roles. For ...
In addition to URL-level security, Spring Security also supports security at the method level. To implement the method-level security using annotations in Spring Security, we can annotate any @Configuration class with @EnableMethodSecurity. Now we can @Secured, @PreAuthorize, @PostAuthorize, @PreFilter, and @PostFilterannotations to authorize metho...
