Responding to Breakin Attempts

[Greg Pavelcak]

We run OpenVMS on an AlphaServer at work, so I'm posting to -chat
because my concerns aren't FreeBSD specific. I'm just looking for the
benefit of the knowledge and experience of people who are more computer
savvy than I am.

The subject almost covers the question.  Our system logs breakin
attempts.  Sometimes we get a flurry of attempts, perhaps just some
sort of script that sends logins and passwords around, and I'd like to
be able to respond in self-defense in some sort of productive way.

How can I respond to such attempts to access the system here?

Any good beginner security reading out there?

Thanks.

Greg
