As of this week, we are changing the cadence for releases for the Snort community rule set. 

Previously, the community rules were released every day at 11:40 a.m. ET, even if there are no rule changes. Now, the rule set will align with our normal open-source build and release schedule. This is usually every Tuesday and Thursday, though this may change based on public holidays and ad hoc releases for certain vulnerabilities or malware families. 

We apologize for any disruptions this may cause.  

Community rules are a set of rules that members of our open-source community or Snort integrators have submitted. These rules are freely available to all Snort users and are governed by the GPLv2. Anyone can submit a community rule using the Snort Rules mailer here. 

Community rules are available for anyone to download here without registration and are free of charge without any Rule Set License restrictions.
