Partitioning Communication System

Partitioning Communication System is a computer and communications security architecture based on an information flow separation policy.

The PCS extends the four foundational security policies of a MILS (Multiple Independent Levels of Security) software architecture to the network: The PCS leverages software separation to enable application layer entities to enforce, manage, and control application layer security policies in such a manner that the application layer security policies are: The result is a communications architecture that allows a software separation kernel and the PCS to share responsibility of security with the application.

The PCS was invented by OIS.

OIS collaborated extensively on the requirements for the PCS with:
