Protection Provided by:	Security Gateway R81, R80, R77, R75
Who is Vulnerable?
Vulnerability Description	Snort is an open source network intrusion detection system (IDS) capable of analyzing network traffic, logging, and dropping individual packets based on user defined rules. The program applies user defined rules to received network traffic in order to detect potentially malicious traffic. Snort is capable of pre-processing traffic before the received data is handed off to be matched against Snort rules. BOPing is a network scanner for the Back Orifice program. It is many times faster than the ping sweeper built in to the original client program. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.
