Protection in the BirliX operating system
Oliver C. Kowalski, Hermann Härtig · 2002
The user-interface-level and implementation-level protection mechanisms of the BirliX operating system are described and motivated. Descriptions are provided of subject restriction and object protection as complementary user-interface-level mechanisms for enforcing security policies by building small domains of protection. Traceability is used as a basis for tracing back violations of policies to answerable humans.>
