Hello,
I'm running securityonion-12.04.1-20130605 and trying to set up some disablesid.conf and/or threshold.conf rules to drop a certain event, but it's not working.

The event I'm targeting is:
  "BAD-TRAFFIC TMG Firewall Client long host entry exploit attempt"

SigID: 
19187
GenID:  1

I made entries:

/etc/nsm/pulledpork/disablesid.conf:
1:19187

and

/etc/nsm/rules/threshold.conf
suppress gen_id 1, sig_id 19187, track by_dst, ip my.dest.ip

did:
# /usr/bin/rule-update

and even rebooted, but the events still show up.

Any thoughts/ideas would be great.

Thanks!

Regards,
Joseph Spenner

Hi Joseph

Could you post the whole rule. I suspect that their might be a flowbit evolved here.

Lysemose:
  Here's the rule:
--
alert udp $EXTERNAL_NET 53 -> $HOME_NET any (msg:"BAD-TRAFFIC TMG Firewall Client long host entry exploit attempt"; sid:19187; gid:3; rev:2; classtype:attempted-user; reference:cve,2011-1889; reference:url,technet.microsoft.com/en-us/security/bulletin/MS11-040; metadata: engine shared, soid 3|19187;)

Thanks!
Interesting though.  That rule (which I got from the "View Rule" button on the web interface) has a different gid.  The web interface itself has Generator ID of 1.  The rule above has 3.    ?

Exactly that's the problem, try disabling or suppressing the rule with 3:19187...

It’s a GID 3 rule.  If you’ve patched a 2011-1889 vuln, I suggest you shut the rule off.
