I've looked into this ad can't seem to find an answer I like. Perhaps
I'm asking the wrong question.
Suppose I have a network consisting of a gateway which goes into a
firewall. The connection from the firewall goes into a switch which
leads to another level of switches. some of these machines are servers,
some are workstations. None of the switches have port mirroring (SPAN
I understand how to set us IDS at the gateway with a stealth interface.
My question becomes, how do I effectively monitor the network. If I put
a tap before each switch, I will not be able to monitor traffic between
2 machines on the other side of the switch, correct?
do I have to run a snort sensor on each server? On each workstation?
Ideally, I'd like to have one sensor for each segment without having to
basically throw away existing hardware and get SPAN switches.
