I would like to setup an IDS/IPS (network intrusion prevention and detection system) like snort, but I would prefer not have to dedicate a computer to handle it.
Are there any applications or routers that can be hacked or some other free or not too expensive IDS that I could use?
I would prefer real time notifications.
I can use pretty much any operating system I guess, that runs on either x64/x86 or custom routers. I have about 50 machines to monitor so not a lot. (Including devices and phones etc). I have a couple of SonicWall routers, and a few dLInk routers. I have one router running ddwrt.
Thanks for all of the responses so far.
