The Security Technical Implementation Guides (STIG) are developed by the Defense Information System Agency (DISA) for the U.S. Department of Defense. They are configuration guidelines for hardening systems to improve security. They contain technical guidance which when implemented, locks down software and systems to mitigate malicious attacks.

DISA has, in conjunction with Canonical, developed STIGs for Ubuntu 20.04 LTS and is available for download at the STIGs document library.
