KSOS Secure UNIX Operating System Users Manuals. (Kernelized Secure Operating System).

Abstract

A maximum of 32 security compartments may be used in a KSOS system. The type independent information (the tii struct) of every object contains a compart set field that determines which security compartments the object belongs, with each bit indicating one compartment. A process may not read an object if the object belongs to any compartments which the process does not belong. A process may not write on an object if the process belongs to any compartments that the object does not belong.
