[Snort-users] Snort and security

What I am trying to do is have my snort box have three interfaces.
One from the outside of the firewall, same switch as firewall and the other
from the inside of the firewall, also same switch as firewall. Both these
interfaces have not IP. The other is on the internal server network. This
has a valid IP for logging to our database.
Will this machine be a security problem for us? Does this pose a security
hole. Is it at all hackable from the outside??
Any suggestions how I can make this more sucure without needing another box

There is no need for the snort box to have an IP address in the same range
as the subnet it is monitoring,
in fact, it needn't have an ip address at all (not all flavours of Unix
support this though).
If you do need to remotely manage the box, then use multiple interfaces,
and manage the box through an interface on the "non dirty side" of the box.
So if it doesn't have an visible address, it is very hard to
attack.....except from internally.
