+
+Infection Monkey is shipped with pre-existing ATT&CK mitigations located at `monkey/monkey_island/cc/setup/mongo/attack_mitigations.json`.
+This allows Monkey Island to be setup faster.
+
+The `attack_mitigations.json` can be updated by running `monkey/deployment_scripts/dump_attack_mitigations.py` by providing the link to
+[Cyber Threat Intelligence Repository](https://github.com/mitre/cti) , mongo host and port information and the dump file location.
+
+When starting Monkey Island this information is stored in the mongo database almost instantly, making the setup faster.
