How do you know, if you don't have a testing dataset yet ?

... so how do you know your method is good ? You haven't evaluated it yet...

That's senseless, since:
a) Snort may have false negatives, or exhibit noncontextual alerts 
because of misconfiguration
b) An anomaly detector should flag things that a misuse detector by 
definition doesn't care about

you need a dataset which is hand labelled, sorry.

Test Your IDS

Is your IDS deployed correctly?
Find out quickly and easily by testing it 
with real-world attacks from CORE IMPACT.
