It is not necessary to assign an IP address to the interface snort is
monitoring, uncheck all the bound components on your ethernet adapter. I
would recommend slapping a second NIC in your sensor and monitoring it from
the backend on a private network.

Also, you may want to consider using a Tap device for true passive
monitoring, they run between $400-$500 US dollars. The OS (regardless of
what platform), the sensor engine, and the planet earth will always be
vulnerable to DoS attacks. Just try and minimize your risk.
