How important is IM? was RE: How important is the PSTN

Despite what security people say, if you are going to use e-mail, the web
or IM, the question is how can you do it safely? Heck, I read a recent
article how even the US military is starting to use a version of IM for
its battlefield coordination of activity.

While "just say no" sometimes applies, competent security understand
the concept of "business need". You're absolutely right about this:

So instead of just saying no, how about coming up with same ways to
solve the how to do it securely.
