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.
