It's a matter of writing non-exploitable code so attack software like
trinoo and tribe don't end up on your systems due to buffer-overflows
in rpc or other services.


I put the emphasis back on the server admins. Security patches were
readily available on the Sun site. Ignoring applicable security patches
for months is likely to get you hacked and abused on todays net.

Combine that with outgoing spoofed IP filters and we are beginning to make
effective countermeasures.

Yes, I will acknowledge the strong tendency to avoid touching a production
server, but scheduled upgrade outages are vastly superior to hitting the
front page as a trinoo source.

Unfortunately all three above point to a need for improvement in the good
netizen department.
