Hi Folks, I have the following question, I just have one machine to monitor the activity on three diferent network segments (Redhat 9), so I plan to to install 3 NIC on the snort machine, setup the interfaces on promiscous mode without IP information and start to listen each segment, I'm kinda worried for the security implications because I'm creating a physcial path between the Internet, DMZ and MZ zones, so in theory there is a small probablity of bypass the Firewall using the snort machine. Can somebody explain what is the risk that I'm facing using this architecture, How can I make sure 100% that the Linux will not route packet between different segments, In wich ways a Hacker can exploit my network ???
Three things: * Taps. * Stealth interfaces (interfaces with no IP). * Read only cables. All mentioned in the Handy-Dandy FAQ!
