security on a multiuser system

You get the picture. There is no security on a multiuser system.

It is possible to get security on a multiuser system (there are at least B3 rated systems out there),

That is fine as long as you trust all the entities that designed, built, (modified :-), programmed, installed, and administer the system. -- Yanek Martinson mthvax.cs.miami.edu!safe0!yanek uunet!medexam!yanek this address preferred -->> yanek@novavax.nova.edu <<-- this address preferred Phone (305) 765-6300 daytime FAX: (305) 765-6708 1321 N 65 Way/Hollywood (305) 963-1931 evenings (305) 981-9812 Florida, 33024-5819
