CIS Ubuntu Linux 24.04 LTS Benchmark

This document provides prescriptive guidance for establishing a secure configuration posture for Ubuntu Linux 24.04 LTS systems running on x86\_64 platforms. This guide was developed and tested against Ubuntu Linux 24.04 LTS The guidance within broadly assumes that operations are being performed as the `root` user, and executed under the default Bash version for the applicable distribution. Operations performed using `sudo` instead of the `root` user, or executed under another shell, may produce unexpected results, or fail to make the intended changes to the system. Non\-root users may not be able to access certain areas of the system, especially after remediation has been performed. It is advisable to verify `root` users path integrity and the integrity of any programs being run prior to execution of commands and scripts included in this benchmark. The default prompt for the `root` user is `#`, and as such all sample commands will have `#` as an additional indication that it is to be executed as `root`.
