Partitioning Communication System

Computer security architecture

Computer security architecture

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:

  • End-to-end Information Flow
  • End-to-end Data Isolation
  • End-to-end Periods Processing
  • End-to-end Damage Limitation

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:

  • Non-bypassable
  • Evaluatable
  • Always-invoked
  • Tamper-proof

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:

  • National Security Agency
  • Air Force Research Laboratory
  • University of Idaho
  • Lockheed Martin
  • Boeing
  • Rockwell Collins
