There is not an option to use a "previous ruleset", you would have to backup your previous ruleset before you update it, since they are in the flat files. What SIDs are giving you the problems? Do you have pcaps for the traffic? After I received your emails I checked my alerts and I don't have either one of these (I'm not a good test case) alerting on my networks. Any more information you can provide? J On Oct 29, 2010, at 1:24 PM, Miso Patel wrote:
Today we installed the newest VRT community rules on our Snort sensors. Almost immediately we started seeing increased alert volume and further investigation shows that these are all false positives. We see *tons* of events for the Microsoft Kodak imaging malformed tiff rules along with other alerts like Mozilla firefox image dragging exploit and more. Right now the SIEM is swamped and I've made the decision to go back to the old rules ... is there an easy way to do this? I don't see them online and my engineers tell me that there is not an option in Snort to instruct it to use the previous ruleset (e.g. snort --use-prev). Any help is much appreciated. Thank you.
