Does some anyone remmember about this question???
--------------
Hello 

Question: 
Is Network Sensor able to analysis packets that doesn´t match a normal HTTP \
connection like a example: reverse telnet through port 80(http)? 

PAM(Protocol Analysis Module) shouldn't detect this protocol anomaly? 

Last weekend my webserver was exploited using "reverse telnet" and I my Network \
Sensor 7.0 was unable to detect this protocol anomaly.

Ps: (Reverse Telnet)http://www.onlamp.com/pub/a/onlamp/2003/05/29/netcat.html 
_-----------------------------------------------------------

Well, now the anomally is detected by Sensors with the new XPU 24.11, PERFECTO!!!!!!!

HTTP unknown protocol
http-unknown-protocol (21259)

Thank you in advance for help!!!!
