  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.
