Best is: You dont run anything that is not needed. If you run only a

For the benefit of people reading the archives in search of clue: There's
a smiley on that, because Peter knows full well that the single biggest
security problem on the Internet is boxes that are running one application,
or end-user boxes, that aren't run in a secure manner because there's nothing
of interest on the box.


though one application means a very simple host, firewall, audit:
1) its running smtp
2) its filtered to permit any -> tcp/25 tcp/25 -> any
3) its log auditor (offline on the log host of course) flags anything NOT
smtp

presume that smtpd is, of course, hardened and patched and looked-after
properly... Sean is right, anything with an ip address is a target,
perhaps not a focused target, but a target none-the-less.

If it's on the internet take proper precautions.

If the box has an IP address, and an Internet connection, it's *always* of
interest, if only as a zombie or a steppingstone box to launder a connection.

oh zombies... where would we be without thee?
