There are two main fronts that I've heard. The first one has already
been brought up here. That is not using root. This provides
rudementry protection of the system as mentioned and is true that
it does not protect user data.
The second is that you use a diversified environment. At work,
We use a few different e-mailers (only a few outlook clients for
home users). A bunch of our people got hit with the file, Only two
people actually opened it. One was my boss and he just did it out
of early morning stuber(this was 7:30). To make matters worse,
about 2 seconds later, a different person sent out the all-company
warning saying don't open these letters....
The other main example i look at is the school I used to attend. A
pure NT/98 shop. They got nailed. I told the admins before they
switched from a staff outlook/student NS mailer to an all outlook for
e-mail that they would run into this problem. Well, This is the forth
time. Previously they got lightly touched but the infection was
pretty slow. This time they got around 99% infected.
Running a diversified client list would have slowed it down and
allowed them to at least prevent any of the student machines from
being infected or prevent the staff machines from being infected.
One more thing to mention as to why it was 99%... The reason
they wanted outlook was so they could use a simple address book
that had every student and facualty member in it...<G> oh yeah
Anyway, The diversified e-mail client system is probably the more
effective to prevent the spread of the virus. At max only 1/n (with n
being the number of clients used assuming an equal distribution
between clients) will actualy be capable of re-sending the virus.
the rest may recieve it and run it, but won't be able to re-send it.
