OAuth2 vs Spring Security: What are the differences?
OAuth2 and Spring Security are security frameworks that serve different purposes. Let's explore the key differences between them.
OAuth2 Authorization Framework: OAuth2 is an open authorization framework used for securely authorizing access to resources. It allows applications to obtain limited access to user accounts using an access token. On the other hand, Spring Security is a powerful and highly customizable authentication and access control framework for Java applications.
Grant Types: OAuth2 supports multiple grant types including authorization code, implicit, client credentials, and resource owner password credentials. Each grant type has different use cases and security considerations. Spring Security, on the other hand, provides a more flexible and extensible approach for handling authentication and authorization. It supports various authentication mechanisms such as in-memory, LDAP, JDBC, and more.
Token-Based Authentication: OAuth2 uses tokens for authentication and authorization purposes. It issues access tokens, refresh tokens, and authorization codes to securely manage access to resources. Spring Security, on the other hand, supports various authentication mechanisms including token-based authentication using JSON Web Tokens (JWT).
Integration with Third-Party Identity Providers: OAuth2 enables integration with third-party identity providers such as Google, Facebook, and Twitter. It allows applications to use OAuth2 to authenticate and authorize users using their existing accounts. Spring Security provides seamless integration with OAuth2, allowing developers to easily configure and manage the authentication process with external identity providers.
Role-Based Access Control: Spring Security provides a robust role-based access control mechanism. Developers can define roles and permissions to restrict access to certain resources based on user roles. OAuth2, on the other hand, focuses more on authentication and authorization using tokens, and does not provide built-in support for role-based access control. However, OAuth2 can be used in combination with Spring Security to achieve role-based access control.
Scalability and Integration: Spring Security offers a wide range of integrations with other frameworks and tools, making it highly scalable and adaptable to different types of applications. It provides seamless integration with Spring Framework, Spring Boot, and other Spring ecosystem components. OAuth2, on the other hand, is a standalone framework that can be integrated with any application or platform, making it suitable for a wide range of use cases and scenarios.
In summary, OAuth2 is an authorization framework that focuses on securely authorizing access to resources using tokens, while Spring Security is a flexible authentication and access control framework for Java applications with built-in support for various authentication mechanisms, role-based access control, and integrations with other frameworks.
I am working on building a platform in my company that will provide a single sign on to all of the internal products to the customer. To do that we need to build an Authorisation server to comply with the OIDC protocol. Earlier we had built the Auth server using the Spring Security OAuth project but since in Spring Security 5.x it is no longer supported we are planning to get over with it as well. Below are the 2 options that I was considering to replace the Spring Auth Server. 1. Keycloak 2. Okta 3. Auth0 Please advise which one to use.
It isn't clear if beside the AuthZ requirement you had others, but given the scenario you described my suggestion would for you to go with Keycloak. First of all because you have already an onpremise IdP and with Keycloak you could maintain that setup (if privacy is a concern). Another important point is configuration and customization: I would assume with Spring OAuth you might have had some custom logic around authentication, this can be easily reconfigured in Keycloak by leveraging SPI (https://www.keycloak.org/docs/latest/server_development/index.html#_auth_spi). Finally AuthZ as a functionality is well developed, based on standard protocols and extensible on Keycloak (https://www.keycloak.org/docs/latest/authorization_services/)
We have good experience using Keycloak for SSO with OIDC with our Spring Boot based applications. It's free, easy to install and configure, extensible - so I recommend it.
You can also use Keycloak as an Identity Broker, which enables you to handle authentication on many different identity providers of your customers. With this setup, you are able to perform authorization tasks centralized.
