[Snort-users] Securing a Snort machine

Here are a few steps to get you going:

Shutdown all unnecessary services.
Make sure the machine is invisible on the network.  No IP address.
Good passwords
I am not sure how you have it set up but any communications to it should be 
encrypted (i.e. SSH instead of telnet)
Also if Snort reports back to a database make sure those communications are 
encrypted as well.  If this is the case you should also be using two NICs, 
one for listening (w/ no IP address) and one for reporting.
