Re: active response and network tap

[Steve Gantz <stephen.gantz () faculty umuc edu>]

Probably not. Typically if you want active response/IPS functionality (drop packets, etc) you need an inline setup with 
two NICs and configuration routing all traffic to Snort using iptables. With a tap the traffic is already downstream by 
the time you get an alert.
