Your of course refering to the 'infamous' C2 utility that comes with the
Windows NT Resource kit. This is for 'Orange Book' compliance only

For those who are not familar with the 'Classic' Rainbow series of
reccomended computer security standards put out by the DOD/NCSC, this
is the story.

The TCSEC 'Orange Book' was the first of the series. Besides defining
the meanings of the term MAC, DAC, I&A, and Audit, it defines a way
to 'measure' security of a computer host. Orange book definitions of
a computer Host is defined as a single isolated computer with no remote
connections. (Besides asking for network connections the WinNT C2 will
also ask if you have floppy drive for DOS system diskettes. Since remote
connections are not allowed, system console access is the only 'certified'
way to access a WinNT host with Pure 'Orange Book').

The TNI ('Red Book') was the second of the series. Its purpose is to
extend the definitions defined in the 'Orange Book' to the context of
of a Computer Network. Both the TCSEC and TNI are U.S. standards. ITSEC
is a European standard based on the TCSEC and the TNI. The current 
discussion concerns ITSEC C2 for WinNT, and postdates the C2
utility that comes with the Resource Kit.

For further information, I'm including the message that K.M. thoughtfully
posted earlier to the list
