This is done by assigning a "domain" to every subject (program) and a "type" to every "object" (file). There is an access matrix to determine which domains have (a particular) access to types. So if you have a type called "executable", only a subject in domain "trusted compiler" would have write access to it. This is a very powerful integrity tool, which will allow us to make some very strong assertions about how (if any) viruses could exist in such a "LOCKed" system.

Any chance of giving us VIRUS-L readers some more information on LOCK? I'm sure we'd all appreciate it.

Abolins: Ooops, my apologies. I had gotten the name wrong for the fellow who is looking for the copy of the RISKS LOG. I still don't have a copy of the original message from here at this site, but I think the name is more like Eric Roskos. But in any case, you know who you are and the offer for the doskette applies to anyone on the VIRUS-L list. (I prefer a stamped self-addressed disk mailer with a diskette or money to cover the disk and mailing.) Also I have sent up the DIRTY DOZEN listing, version 8 b. This came out in April 1988. J.D.
