This is one thing in [system] security that we often tend to overlook.
Penetration happens one tiny little step at a time. Say, you are running
[some untrustworthy] code on your machine (or system) solely dedicated to
scanning mail. You feel safe about mail. But you already let some
potentially unfriendly one to run his code on your system. One tiny step
on his part is already achieved with your consent. This is what I was
trying to say. We used to say about security part of our sysadmins duties:
paranoia is in my job description. And I apparently failed to stress it
enough. It looks like I definitely had much better in that respect
teachers than I can be (well, not thinking of myself as a teacher, but a
person trying to pass the point along).
