Often times while building a web system you may have certain users who operate at an elevated security level. The PageManager itself can operate some security features to prevent certain users from accessing parts of the PageManager tree. This security operates at the Page Node level, and the ability for a particular request to be routed successfully to the Page node it requested. If the PermissionsAuthority does not allow access to the node, routing to the node will fail. One could imagine disallowing any users who do not have Admin privileges access to any node off the Admin branch. Although this level of access control should not be the first line of defense, it provides a low level protection against certain parts of the tree. Apollo only provides an interface for a Security object to be supplied, and does not make security decisions on its own.
