Am I Being Hacked?

[Ed Rivenbark]

  You can never be too paranoid about network security.  IP spoofing is
very possible, I have done it.  You can spoof an internal IP that will
allow you to gain access to network resources.  If you have an insecure
machine they can use it as a host to try to break into your system.  As
mentioned before, I would check out the machine with the internal IP
that was trying to get access via FTP.  This machine may be insecure and
allowing access from outside connections.

Well see that is the thing I have gone to great lengths to block
everything
out with hosts.deny and .allow. My concern is that they will address
spoof
the allowed IPs and get in. Is this possible or am i being paranoid?
