In it we shall provide an illustration where these threats are confronted, describe the
three basic techniques of authentication, and comment on the various methods of
access control. We go on to explain information compartmentalization, information
disclosure policies, preventing the unauthorized modification of data, and audit logs.
Finally we outline a hybrid approach for access control that incorporates strong
authentication and uses an access control tree to represent privilege.
Our system is real-time, perimeter based, community centric, and user friendly.
The intelligent security decision that results from using an access control tree is
commendably better than any current system. With our access control system we can
dynamically determine capability based on real world conditions by incorporating
security information from external data sources, software agents, as well as location
