Partitioning Communication System
Encyclopedia
Partitioning Communication System is an high-assurance computer 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
) separation kernel
to the network:
The PCS leverages the separation kernel
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 the 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:

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:
- Non-bypassable,
- Evaluatable,
- Always-invoked, and
- Tamper-proof.
The result is a communications architecture that allows the separation kernel and the PCS to share responsibility of security with the application.
