[Snort-users] [Snort-sigs] Snort EOL Reminder

I've been curious what the differences between the ET paid rules and the VRT subscription rules are? I'm hoping this can be discussed without opening a huge flame war. :)  For background, I'm currently running the VRT subscription rules with the ET free rules.

For instance, the VRT is part of the MS program that releases vuln data early (and typically these rules are .so rules).  Does ET get this data?  How do they deal with non-disclosure, since I think all the rules are text based?

For the most part, is everything in the VRT ruleset covered in the ET ruleset?  Could I drop VRT for instance and just run ET pro?

Thanks for the reminder, Joel.  Those who can't upgrade to a newer or newest version of Snort, or wish to use a different ruleset alongside, or instead of the VRT set, should definitely check out Emerging Threats Pro -- http://www.emergingthreatspro.com/.  The Emerging Threats Open rules are free and updated almost daily to respond to the latest threats and I have found them to be quite effective, timely, and properly QAed.  There are also some you can pay for as well (cheaper than VRT I think); see http://www.emergingthreatspro.com/products/ for details.

Emerging Threats Open/Pro supports rules for Snort 2.4.0 up to the current version, as well as rules optimised for Suricata (http://www.openinfosecfoundation.org/index.php/download-suricata).
Personally, I like https://rules.emergingthreatspro.com/open-nogpl/.

That said, if you are still running an older version of Snort, I highly encourage you to update since there are a lot of new and extremely helpful features in newer versions that allow for more accurate and efficient rules.
