# The Ubuntu Security Guide

Security Technical Implementation Guides like the [CIS benchmark](https://ubuntu.com/security/cis) or [DISA-STIG](https://ubuntu.com/security/disa-stig) have hundreds of configuration recommendations, so hardening and auditing a Linux system manually can be very tedious and error-prone. Ubuntu Security Guide (USG) is a new tool available with Ubuntu 20.04 LTS that greatly improves the usability of hardening and auditing, and allows for environment-specific customizations. The following sections provide more information on hardening and auditing with usg.

* [Installation](https://ubuntu.com/security/certifications/docs/disa-stig/installation)
* [Hardening for DISA-STIG](https://ubuntu.com/security/certifications/docs/disa-stig)
* [Hardening with the CIS benchmark](https://ubuntu.com/security/certifications/docs/usg/cis)
