Checklist Summary:

Ansible is an open source, cross-platform configuration management solution used to define and enforce system and application configurations. This package provides Ansible configurations that implement most of the Canonical Ubuntu 18.04 LTS STIG. While the content has been tested during development, all possible system and environmental factors could not be tested. Before using this content in a production environment, please perform testing with the intended settings in your own test environment. There is no mandate to use this content; it is published as a resource to assist in the application of security guidance to your systems. Use it in the manner and to the extent that it assists with this goal.

Comments/Warnings/Miscellaneous:

Comments or proposed revisions to this document should be sent via email to the following address: disa.stig_spt@mail.mil.

Approved changes will be made in accordance with the DISA maintenance release schedule.

Disclaimer:

DISA accepts no liability for the consequences of applying specific configuration settings made on the basis of the SRGs/STIGs. It must be noted that the configuration settings specified should be evaluated in a local, representative test environment before implementation in a production environment, especially within large user populations. The extensive variety of environments makes it impossible to test these configuration settings for all potential software configurations. For some production environments, failure to test before implementation may lead to a loss of required functionality. Evaluating the risks and benefits to a system’s particular circumstances and requirements is the system owner’s responsibility. The evaluated risks resulting from not applying specified configuration settings must be approved by the responsible AO. Furthermore, DISA implies no warranty that the application of all specified configurations will make a system 100 percent secure. Security guidance is provided for the DoD. While other agencies and organizations are free to use it, care must be given to ensure that all applicable security guidance is applied at both the device hardening level and the architectural level due to the fact that some settings may not be configurable in environments outside the DoD architecture.
