Decider – A Web Application That Assists Network Defenders, Analysts, And Researcher In The Process Of Mapping Adversary Behaviors To The MITRE ATT&CK Framework

What is it?

The Short

A web application that assists network defenders, analysts, and researchers in the process of mapping adversary behaviors to the MITRE ATT&CK® framework.

The Long

Decider is a tool to help analysts map adversary behavior to the MITRE ATT&CK framework. Decider makes creating ATT&CK mappings easier to get right by walking users through the mapping process. It does so by asking a series of guided questions about adversary activity to help them arrive at the correct tactic, technique, or subtechnique. Decider has a powerful search and filter functionality that enables users to focus on the parts of ATT&CK that are relevant to their analysis. Decider also has a cart functionality that lets users export results to commonly used formats, such as tables and ATT&CK Navigator™ heatmaps.

There are some issues in the instructions… Working on it, simplifying them

Help Tips:

  • Use Python 3.8.10 / 3.8.x on Linux / mac
  • Follow the order of instructions
  • Watch out using sudo with python – it won’t keep the venv you’re in by default
  • If just running for yourself locally:
    • Don’t create a system account for decider
    • Don’t use uWSGI
    • Use the built-in debug Flask server
  • Mac M1 users should install Postgres before installing the pip requirements
    • brew install postgresql
    • Explained: psycopg2-binary isn’t using a pre-built binary and tries to compile from scratch, and it can’t find pg_config.
