What is Spring Security used for?
The most popular option for implementing application-level security in Spring applications is Spring Security. Authentication, authorization, and protection against common attacks are generally its main goals, and they are all highly customizable.
What is meant by configuration in Spring?
The spring core framework includes the Spring @Configuration annotation. The class’s @Bean definition methods are indicated by the Spring Configuration annotation. In order to create Spring Beans for use in the application, the Spring container can process the class.
What are the types of Spring Security?

- Localization of software.
- Remember-me.
- LDAP (Lightweight Directory Access Protocol) (Lightweight Directory Access Protocol)
- JAAS LoginModule (Java Authentication and Authorization Service).
- Authentication for web forms.
- Digest Authentication for Access.
How do you configure security to a Spring application?

What is JWT token in spring boot?
An open Internet standard (RFC 7519) for securely and compactly transmitting trusted information between parties is JSON Web Token, or JWT as it is more commonly known. The claims in the tokens are digitally signed with a private secret or a public key/private key pair and are encoded as JSON objects.
How do I use Spring Security in REST API?
A simple secure REST API
- Provide a UI with a button that sends a request to a back-end endpoint.
- Provide a username and password field for users to log in.
- If the API button is clicked and the user is not logged in, reject the endpoint call with a “HTTP 401 Forbidden” response.
Is Spring Security necessary?
For Java developers, the Spring Security framework is a dependable tool for application security. To avoid the most common vulnerabilities, proper implementation is essential.
What problems does Spring Security solve?
In addition to authentication and authorization, Spring Security can be set up to defend your application against a variety of common attacks, such as MITM (Man in the Middle), CSRF, XSS, and brute force. If you’d like to learn more about these attacks, check out this article by Holly.
Can we use @bean without @configuration?
Classes not annotated with @Configuration are still permitted to declare @Bean methods. Bean methods, for instance, might be declared in a @Component class or even just a regular class. A @Bean method will be processed in a so-called “lite” mode in these circumstances.
What is the difference between @configuration and EnableAutoConfiguration?
How They Vary. The primary distinction between these annotations is that @ComponentScan searches for Spring components while @EnableAutoConfiguration is used in Spring Boot applications to automatically configure beans found on the classpath.
How many ways we can implement Spring Security?
Spring security can be implemented in essentially 2 different ways. using annotations and bean configuration in.xml files, among other methods. Given that it is less ambiguous, the annotation-based method is simple to use over time.
What is Spring Security user name?
When your Spring Boot project launches, the default username is user, and the default password is printed in the console.
What is CSRF in Spring Security?
Cross-Site Request Forgery is referred to as CSRF. A web application in which the end user is currently authenticated is subjected to an attack that compels them to carry out unwanted actions.
What is the difference between Spring Security and JWT?
Compared to Spring Security, which is listed in 12 company stacks and 9 developer stacks, JSON Web Token has a wider acceptance, being mentioned in 29 company stacks and 15 developers stacks.
What is OAuth2 in spring boot?
OAuth2 is a framework for authorizing access that allows the Web Security application to use client-side resources. We must concentrate on the Grant Type (Authorization code), Client ID, and Client secret when developing an OAuth2 application.
What is @controller and @RestController?
Spring MVC controller classes are identified by the annotation @Controller. A unique controller called a @RestController, which combines the @Controller and @ResponseBody annotations, is used in RESTful Web services. It’s a particular application of the @Component annotation.
What is the difference between @bean and @component?
@Component can only be used when a class’s source code is editable because it is a class-level annotation while @Bean is at the method level. It is always possible to use @Bean, but it is verbose. Unlike @Bean, which necessitates manual class instantiation, @Component is compatible with Spring’s auto-detection.
Can we use @bean at class level?
You are not placing this annotation at the class level when you use @Bean. You would encounter an invalid type error if you attempted to do that. According to the @Bean documentation, it is: shows that a method creates a bean that the Spring container can manage.
What is difference between @component and @controller?
The basic auto component scan annotation @Component indicates that the class being annotated is an auto scan component. The class’s annotation, @Controller, identifies it as a controller component that is primarily used at the presentation layer.
What is difference between @component and ComponentScan?
The purposes of @Component and @ComponentScan differ. A class may be a candidate to create a bean, according to the @Component annotation. It resembles raising your hand. @ComponentScan looks for components in packages.
What is difference between @autowired and @inject?
Both the annotations @Inject and @Autowired are utilized for autowiring in your application. While @Autowire annotation is a part of the spring framework, @Inject annotation is a part of Java CDI, which was introduced in Java 6. Both annotations serve the same purpose, so we can use either one in our application.
What is the latest version of Spring Security?
Spring Security
- newest iteration. 5.7.3.
- the most recent secure version. 5.7.3.
- initial publication 14 years prior.
- latest published version. a week ago.
- licenses are found. Apache-2.0. [0,)
- program manager. On the Maven Repository, look.
How JWT is implemented in Spring boot?
We are implementing a REST API and need stateless authentication with a JWT token; therefore, we need to set the following options:
- Turn on CORS and off CSRF.
- Stateless session management is selected.
- Create an exception handler for unauthorized requests.
- Set endpoint permissions.
- JWT token filter added.
What is dependency injection in spring?
A key component of the Spring framework is dependency injection, which allows the Spring container to “inject” objects into other objects or “dependencies”. Simply put, this permits loose coupling of components and shifts component management duties to the container.
What is CORS and CSRF?
A vulnerability is CSRF, and a way to relax the same-origin policy is CORS. In contrast to CSRF, which you should avoid using, CORS is something you might want to use (under certain conditions). There are weaknesses in the CORS mechanism.
What is XSS and CSRF?
Cross-site scripting (or XSS) enables an attacker to run any JavaScript they choose within the victim user’s browser. By using cross-site request forgery (also known as CSRF), an attacker can trick a victim user into doing something they did not mean to.
Is JWT same as OAuth2?
Despite the fact that JWT and OAuth2 are completely dissimilar and have different functions, they can still be used together. JWTs can be used with OAuth2 because the OAuth2 protocol does not specify the format of the tokens.
WHO issues JWT token?
JSON Web Token
| Abbreviation | JWT |
|---|---|
| Organization | IETF |
| Committee | IEGS |
| Authors | Michael B. Jones Microsoft John Bradley Ping Identity Nat Sakimura NRI |
| Base standards | JSON JSON Web Encryption (JWE) JSON Web Signature (JWS) |
How do I use Spring Security in REST API?
A simple secure REST API
- Give a user interface (UI) button that requests something from a back-end endpoint.
- Give users a space to enter their username and password to log in.
- The endpoint call should be rejected with a “HTTP 401 Forbidden” response if the API button is clicked but the user is not logged in.
What is JWT token in REST API?
A JWT is what? When engaging in a two-party interaction, you can securely represent the identity of your users by using JSON Web Tokens, which are open and standard (RFC 7519). In other words, instead of sending private credentials with each request, you can use a JSON Web Token to identify your user when two systems exchange data.
What is OAuth configuration?
You can configure authentication settings for OAuth 2.0 as a client at the global level with OAuth 2.0 client credential profiles. A specific OAuth client application and the information about an OAuth service provider make up an OAuth 2.0 credential profile. The authorization and token endpoints are specified by an OAuth service provider.
How OAuth2 works with rest?
OAuth2 enables authorization without revealing the user’s email address or password to the external application. Instead, a token that permits access to the user’s account is provided to the external application. The token for one application can be revoked by the user without affecting access for any other applications.
What is the difference between API key and OAuth?
If you anticipate that developers will create internal applications that don’t require access to the data of more than one user, use API keys. If you want users to easily authorize applications without having to share sensitive information or sift through developer documentation, use OAuth access tokens.
Why is OAuth better than basic authentication?
OAuth is the way to go for better online account security because, unlike Basic Auth, it doesn’t reveal your password. OAuth is more of an authorization framework, which explains why. This safeguards your login information.
How JWT works in microservices?
For the subsequent service calls, each microservice can create a new JWT signed by itself and send it along with the request after validating the JWT it receives. Another strategy is to use nested JWTs, which will allow the new JWT to carry both the old and new JWTs.
