NIST SP 800-171 Rev 2¶
The National Institute of Standards and Technology (NIST) Special Publication 800-171 Revision 2 provides guidelines for protecting Controlled Unclassified Information (CUI) in non-federal systems and organizations. Published by the U.S. Department of Commerce, this framework is mandatory for contractors and subcontractors handling CUI on behalf of the federal government. It is widely used across defense industrial base companies and federal contractors throughout the United States.

Enable/Disable Controls¶
You can customize the Terraform module for the desired compliance requirements by enabling/disabling individual controls.
Examples¶
S3 bucket module with NIST SP 800-171 Rev 2 compliance framework controls enabled, and a couple of controls disabled¶
