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

HTTPS Cert Location:
- Write these 2 files before
docker compose up
to set your SSL cert up- /app/utils/certs/decider.key
- /app/utils/certs/decider.crt
- If either file is missing, a self-signed cert is generated and used instead

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
withpython
- 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.
