[comp.sys.mac.misc] TECHNICAL INFO needed: hard drive protection

derek@coco2.albany.edu (Cinderella Man) (03/09/91)

At SUNYA, we are in the process of installing 40MB HDs and RAM upgrades
into all of our user room SEs, finally rendering them useful.  However,
with hard drives comes the need for protection: from copying, deleting,
or modifying files, and from viruses.

I've been pushing for buying MacPassword, which seems appropriate and
solid, but the price is high -- and with our state budget in limbo, hard
to pay.  So I'm looking into other alternatives.

What I'd like to do is partition the hard drives into "startup" and
"temp" volumes, of 35MB and 5MB respectively.  I'd then put DiskLock
on the startup volume, and let users use the temp volume as a storage
place. Disinfectant and its companion INIT would be used for virus 
checking.

However, this scheme can be defeated by booting with a floppy, so my
question for the net.mac.techies is:

          How can I prevent the Mac from booting with a floppy?

Is there a way of modifying either the Shutdown Manager (or boot blocks,
or whatever) to make the startup routine ignore any disks in the FDs?

Any technical information and suggestions are much appreciated.  E-mail
or post, whichever is appropriate.

                                    Thank you!

                                               Derek L.
