Re: problem tuning out one particular rule

Speaking from the perspective of PulledPork, that rule is re-enabled because
it sets a flowbit that other rules (that are enabled) rely on.  As to the
suppression, are you sure that the source is 10.0.0.0/8 and that it's not
the dest?

   So I’ve been doing some Snort tuning over the last couple weeks.  I’m
using Snort 2.9.0.4, Barnyard2, and PulledPork 0.5.  There’s this one event
signature “WEB-CLIENT Portable Executable binary file transfer” (sid: 15306)
and I’ve been trying to tune it out, but it still keeps on firing.



I have it in the disablesid.conf

# WEB-CLIENT Portable Executable binary file transfer

1:15306



I also put it in the threshold.conf as well

# ignore these WEB-CLIENT Portable Executable binary file transfer

suppress gen_id 1, sig_id 15306, track by_src, ip 10.0.0.0/8



Yet, the rule keeps firing.  All of the other rules I’ve ignored using the
methods above have worked, so not sure what’s different about this
particular rule.



Thoughts?



Thanks.
