(Signatures Observed Working)

Overview

A simple voting system integrated into Snort signature test environment. Designed to prevent the rollout of bad signatures into a production environment. Easiest method to determine the validity of signatures with minimal impact on testers.

What you'll need

• Snort running on your choice of OS(preferably Linux, *BSD, or Solaris)
• Web front-end for evaluating Snort signature trips.
  • Take your pick as to which one you want to use and mod it, or make your own.

Features

• For each signature that trips on the test system the user is presented with a voting system similar to a simple poll in a blog.
  • User has three options when evaluating a signature trip:
    • Good: The signature tripped on what it was designed to and the traffic is hostile in nature.
    • Needs work: Either the signature tripped on what it was supposed to but the traffic isn't necessarily hostile, or the traffic is hostile but the signature could use some tightening.
      • A brief note will need to be provided with reasoning and/or suggestions.
    • False: The signature trips on normal/non-hostile traffic(false positives).
      • A brief note will need to be provided with reasoning.
  • Will support multiple users.
    • Simple metrics will be kept on user interaction with the system.
      • Shows how often certain users participate in the signature testing.
      • Shows general differences in user analysis of similar signature trips.
  • Reports can be generated at any point to determine the performance of any individual signature or as a whole.
    • or any individual user or as a whole for that matter.
