Spring Security

Spring Security is a powerful and highly customizable authentication and access-control framework for Java applications. It is the de-facto standard for securing Spring-based applications, providing comprehensive security services including authentication, authorization, protection against common exploits (CSRF, session fixation, clickjacking), OAuth 2.0, OpenID Connect, SAML 2.0, LDAP, and WebFlux reactive security.

Spring Security publishes 8 APIs on the APIs.io network, including Authorization API, Client Management API, Device API, and 5 more. Tagged areas include Authentication, Authorization, Java, JWT, and OAuth2.

The Spring Security catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Spring Security’s developer surface includes authentication, engineering blog, changelog, and 9 more developer resources.
