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 ports). 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. -- Stewart Larsen ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
