Download Rules


Snort rule packages for Subscribers and Registered users track the latest feature set for any Major.X release. This means that rule packages can contain features that only exist in the latest version of snort for a given Major.X release. A simple example is:

If 2.6.1.5 is the current version of snort then the snortrules-snapshot-2.6 packages might utilize features not supported in 2.6.1.4 and earlier.

Additionally the word CURRENT does not mean "current" as in the English dictionary meaning. It mean CURRENT in the BSD source code repository meaning. CURRENT tracks SNORT CVS CURRENT, i.e. the the unstable, possibly broken version of snort. If you download CURRENT and are not running this version of snort, your snort install will break.

Download Policy: Please note that you may only download each file once every 15 minutes. Please set your cron jobs to run no more than once per hour. VRT Subscribers are currently exempt from this policy.
