I think you misunderstood my question. I wasn't asking if one could use Snort to protect Snort.

Date: Mon, 9 Sep 2002 20:42:47 -0700 (PDT) I wouldn't use snort to protect the sensor. On top of what V. wrote, Snort protects *itself* by running as a normal user with no shell, and by not using shoddy programming (no buffer overflows on bugtraq :). Using Snort to protect your sensor is like using the back of a screwdriver as a hammer. It would be a better idea to do the traditional grunt work of hardening the OS by pruning useless services, patching it, and firewalling it. --- "Vinay A.
