Security

Liferay DXP is built with security in mind. A variety of standards based authentication methods and integrations can be used to ensure secure access to a site and its resources. Robust role-based access control with permissions gives you fine grained control over what authenticated and unauthenticated users can access, share, or edit. Liferay DXP’s web services also have a multi-layered and configurable approach to security and authorization.
