I'm working with a ids 4230 (3.0(5)S17) and a CSPM
I've properly configured the sensor to detect events
related to standard ip attack or connection events.
I've seen that the configured reply for those events (ip blocking, logging and TCP reset) work well but at the event viewer tool I don't see the connection events configured instead the classic ip attack are showed.
Could anyone give me some explanation? I've to change some parameters of the event viewer???
TCP Connections are part of the 3000 TPC Connection signature.
The specific port is the subsignature.
So a telnet ot port 23 would create a 3000 signatures with a 23 subsignature.
UDP connection are similar with the 4000 UDP signature.
These subsignatures can each be assigned a severity level.
The typical severity that people set is low (or 1).
The sensor can both log events and send events to the CSPM box.
By default the sensor will log low severity events and higher, but by default only medium severity events and higher are sent to CSPM.
So if you are not seeing the 3000 signature with subsignature 23 for the telnet connection in your CSPM, then check to see what severity the subsignature has been set to, and check what severity is being sent to CSPM (look in the filters tab).
You may need to raise the severity for the telnet connection to Medium, or you may need to lower the severity of alarms you send to CSPM to Low.
