As far as I know Digital UNIX is NOT C2 certified. (Which reminds me, my NSA
catalog hasn't arrived.) However, it was designed to be C2 compliant. When we
went to run Digital UNIX in classified system high mode we had to sit down with
the DIS AIS representative and demonstrate to him every aspect of C2 compliance
in order to get permission to use it. Object reuse was especially difficult to
demonstrate, since we had to show that blocks on the disk were zeroed when
deallocated. (I believe Digital UNIX satisfies the object reuse requirement by
zeroing on deallocate. Some OSs do zero on allocate, some can do both.)
