RE: Test scripts for NIDS

[Bénoni MARTIN <Benoni.MARTIN () libertis ga>]

There is a Windoze tool called RafaleX (was named after in Engage Packet Builder, if I am right), free, which allows to 
forge TCP/UDP/ICMP traffic via a very nice GUI.

I think you can also tell him how many packets you want to send ...

You need a traffic generator. The best layer 4-7 generator available, in my opinion, is Spirent Avalanche/Reflector. 
But it's expensive. I'd like to hear if someone has actually used a good non-commercial or cheaper solution to do this 
where real stateful traffic is created rather than dummy packets for load testing purposes. I still hold the opinion 
that this tool is required to perform a proper load/stress test because nothing comes close to its power and 
application protocol support.

Use exploit toolkits like Metasploit or CANVAS or compile your own which are available from the Internet. 
Alternatively, there are attack replay tools like Blade IDS Informer or you can use the tcpreplay tool to replay pcap 
files.

Refer to http://osec.neohapsis.com/ and
http://www.nss.co.uk/Articles_wpapers.htm for more ideas on testing NIDS.
There are many variations you can perform for testing NIDS effectiveness while it is under load from different sorts of 
traffic.
