Adding a new Security Threat

1. Fork and clone this repository
2. Copy res/threatTemplate.yaml template file in threats/tactic directory and edit the file's contents to accurately reflect the specific threat information. For e.g., execution tactic from MITRE FiGHT.

   cp res/threatTemplate.yaml threats/execution/threat-name.yaml

3. Create the Security Actions file(s) you listed in the .securityActions field of the threat-name.yaml file, and place them within the actions directory. For e.g.,

   ...
   securityActions:
    - sample-sa-1.yaml 
    - sample-sa-2.yaml 
   ...

4. Run make
5. Raise a PR
