New Proposed Classification.config file setup

I know we are all in the Holiday Season, so one last item for you all to look over while you are roasting in front of the fire..

Recently on the Emerging-Threats Mailing list, Matt Jonkman proposed a new classification system to replace the aging Snort classification system that's been in use for years. We saw this as a good idea and after some internal discussions, decided to head the same route.

So we propose the following classification.config system to the community for comment, and we want to hear the feedback! Especially on descriptions and priorities. I'll assemble all the comments on January 12th (a date suggested by Matt Jonkman) and create a new classification.config file which we will then include in the official Snort tarball and in the VRT rules tarball.

We've made two major changes to the classification system as proposed by the Emerging-Threats list:
  1. We've converted all Underscores to Hyphens
  2. We've made everything lowercase.

This was done to ensure compatibility with existing output modules (barnyard2, unified, unified2, barnyard, SnortUnified.pm, etc), GUI's (BASE, Snorby, Placid, etc), and internal (to Snort) parsers.

The proposed classification.config configuration parameters are available for download here:
http://www.snort.org/assets/157/classifications.txt, and are pasted below. Please leave comments on the blog, and we'll assemble them into a final product:
