Snort.org is the official authority for Snort rule docs. The docs are updated at least twice a week, so we want you to link to them to ensure you are getting the most updated version. PulledPork will no longer request the opensource.gz file, and future requests will be met with a 422, 404 or 403 error. Tools available on the internet and integrators of our ruleset onto their boxes are encouraged to create these links to Snorts.org directly from their interfaces as well.”]
