Project Guardian

   <project, security> A project which grew out of the {ARPA}
   support for {Multics} and the sale of Multics systems to the
   US Air Force.  The USAF wanted a system that could be used to
   handle more than one security classification of data at a
   time.  They contracted with {Honeywell} and {MITRE
   Corporation} to figure out how to do this.  Project Guardian
   led to the creation of the {Access Isolation Mechanism}, the
   forerunner of the {B2} labeling and star property support in
   Multics.  The {DoD Orange Book} was influenced by the
   experience in building secure systems gained in Project
   Guardian.
