Access to all contents controlled by OpenCms is optionally restricted by an elaborate user and access permission management system. This guarantees controlled access to protected areas and allows easy creation of non-public areas (e.g. extranet sites).

For every resource in OpenCms, an access control list (ACL) can be defined, allowing fine-grained control about who is allowed to access or modify the resource. ACLs of a folder can be inherited to all resources in the folder. Inherited permissions can also be overwritten on subresources if necessary.
