canonical-ubuntu-20.04-lts-stig-baseline

InSpec profile to validate the secure configuration of Ubuntu 20.04, against DISA's Canonical Ubuntu 20.04 LTS Security Technical Implementation Guide (STIG) Version 1, Release 6.

Getting Started

It is intended and recommended that InSpec run this profile from a "runner" host (such as a DevOps orchestration server, an administrative management system, or a developer's workstation/laptop) against the target remotely over ssh.

For the best security of the runner, always install on the runner the latest version of InSpec and supporting Ruby language components.

Latest versions and installation options are available at the InSpec site.

Tailoring to Your Environment

The following inputs must be configured in an inputs ".yml" file for the profile to run correctly for your specific environment. More information about InSpec inputs can be found in the InSpec Profile Documentation.

Running This Baseline Directly from Github

# How to run
inspec exec https://github.com/mitre/canonical-ubuntu-20.04-lts-stig-baseline/archive/master.tar.gz --target=ssh://<your_target_host_name_or_ip_address> --user=<target_account_with_administrative_privileges> --password=<password_for_target_account> --sudo --sudo-password=<sudo_password_for_target_if_required> --input-file=<path_to_your_inputs_file/name_of_your_inputs_file.yml> --reporter=cli json:<path_to_your_output_file/name_of_your_output_file.json>

Running This Baseline from a local Archive copy

If your runner is not always expected to have direct access to GitHub, use the following steps to create an archive bundle of this baseline and all of its dependent tests:

(Git is required to clone the InSpec profile using the instructions below. Git can be downloaded from the Git site.)

When the "runner" host uses this profile baseline for the first time, follow these steps:

mkdir profiles
cd profiles
git clone https://github.com/mitre/canonical-ubuntu-20.04-lts-stig-baseline
inspec archive canonical-ubuntu-20.04-lts-stig-baseline
inspec exec <name of generated archive> --target=ssh://<your_target_host_name_or_ip_address> --user=<target_account_with_administrative_privileges> --password=<password_for_target_account> --sudo --sudo-password=<sudo_password_for_target_if_required> --input-file=<path_to_your_inputs_file/name_of_your_inputs_file.yml> --reporter=cli json:<path_to_your_output_file/name_of_your_output_file.json>

For every successive run, follow these steps to always have the latest version of this baseline:

cd canonical-ubuntu-20.04-lts-stig-baseline
git pull
cd ..
inspec archive canonical-ubuntu-20.04-lts-stig-baseline --overwrite
inspec exec <name of generated archive> --target=ssh://<your_target_host_name_or_ip_address> --user=<target_account_with_administrative_privileges> --password=<password_for_target_account> --sudo --sudo-password=<sudo_password_for_target_if_required> --input-file=<path_to_your_inputs_file/name_of_your_inputs_file.yml> --reporter=cli json:<path_to_your_output_file/name_of_your_output_file.json>

Viewing the JSON Results

The JSON results output file can be loaded into heimdall-lite for a user-interactive, graphical view of the InSpec results.

The JSON InSpec results file may also be loaded into a full heimdall server, allowing for additional functionality such as to store and compare multiple profile runs.
