Vendor: IBM ISS.
Product: RealSecure Network 10/100 and Gigabit
Feature small description.
Logevidence is one of the possible signature responses in ISS' NIDS. It forces the sensor to dump packet which contains signature to file specified in sensor configuration file.
Problem description.
1. Sensor dumps only one packet per signature.
2. All logevidence packets are dumped to the same file and to find something in it is very difficult.
Enhancement description.
1. We know that ISS produce good stateful NIDSs. This means that to find signature sensor analyzes not just one packet (in this case fragmentation will easily deceive it) but whole data stream (session, which is more than one packet). As far as I understand idea of Logevidense, it is for further manually analysis. In this case one packet is not enough. So, my first part of this enhancement here is to dump the whole session, not just one packet.
2. Dump packets (sessions) not only to one file but to special folders structure. For example, like this:
Of cource ability to configure neded path and file name for logevidence is welcome!
