no idea. Since this affects both developers AND users, I e-mailed

Thats a simple change in your classification.config
Since many NIDS shops use RealSecure and snort, I've elected to make
the default priorities follow sort of the same scheme. (With a bit
more brain cells to classifying rules, that's for sure)
If there is a generalized consent that we want priorities done in low
to high instead of high to low, then I'll change it. NOTE: That
means if you want it, you MUST speak up.

Actually, I do. One is an exploit. One is just a probe. I'm much
more concerned if someone does /scripts/../../../winnt/cmd.exe than if
they do /cgi-bin/phf

host-mapping would contain NMAP probes, and things host -> many hosts
targetting a single port. Actually, I will be releasing HOMER soon,
an alert correlation engine that we at MITRE have developed. (See the
SANS paper on Intrusion Detection & Data Mining) This classification
is used by those things.
