For VRT rules you can report FPs here:
http://www.snort.org/snort-rules/submit-a-false-positive

<http://www.snort.org/snort-rules/submit-a-false-positive>or you can drop an
email to research () sourcefire com

The snort signatures have a priority associated with them, either in

signature is recorded?


No.  There has been a lot of discussion regarding whether or not
something like that would be helpful.  I think the short answer is
that environments and preferences vary too widely to be able to
effectively communicate a signature's fidelity.  I would also argue
for those same reasons priority should not be suggested either and it
should be deprecated.

Seems like there'd almost need to be a central place that various
entities could report their findings. I know we've got rules that we
rely on heavily and work very well for us, but other than mailing lists
there's no place to report our findings.

Anyone want to volunteer ? Sounds trivial :-p
