What is NIST SP 800-171?
NIST SP 800-171 focuses on protecting the confidentiality of Controlled Unclassified
Information (CUI) in nonfederal systems and organizations. It recommends specific security
requirements to achieve that objective. NIST 800-171 is a publication that outlines the
required security standards and practices for nonfederal organizations that handle CUI on
their networks. It was first published in June 2015 by the National Institute of Standards and Technology
(NIST)
The cybersecurity controls within NIST SP 800-171 safeguard CUI in the IT networks of government contractors and subcontractors. It defines the practices and procedures that government contractors must adhere to when their networks process or store CUI. NIST SP 800-171 only applies to those parts of a contractor’s network where CUI is present.
Using this framework
You can use the NIST SP 800-171 framework to help you prepare for audits. This framework includes a prebuilt collection of controls with descriptions and testing procedures. These controls are grouped into control sets according to NIST requirements. You can also customize this framework and its controls to support internal audits with specific requirements.
Using the framework as a starting point, you can create an Audit Manager assessment and start collecting evidence that’s relevant for your audit. After you create an assessment, Audit Manager starts to assess your AWS resources. It does this based on the controls that are defined in the NIST SP 800-171 framework. When it's time for an audit, you—or a delegate of your choice—can review the evidence that Audit Manager collected. Either, you can browse the evidence folders in your assessment and choose which evidence you want to include in your assessment report. Or, if you enabled evidence finder, you can search for specific evidence and export it in CSV format, or create an assessment report from your search results. Either way, you can use this assessment report to show that your controls are working as intended.
The framework details are as follows:
| Framework name in AWS Audit Manager | Number of automated controls | Number of manual controls | Number of control sets |
|---|---|---|---|
| NIST 800-171 Revision 2: Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations | 58 | 52 | 14 |
Important
To ensure that this framework collects the intended evidence from AWS Security Hub, make sure that you enabled all standards in Security Hub.
To ensure that this framework collects the intended evidence from AWS Config, make sure that you enable the necessary AWS Config rules. To review the AWS Config rules that are used as data source mappings in this standard framework, download the AuditManager_ConfigDataSourceMappings_NIST-800-171-Rev-2.zip file.
The controls in this AWS Audit Manager framework aren't intended to verify if your systems are compliant with NIST 800-171. Moreover, they can't guarantee that you'll pass a NIST audit. AWS Audit Manager doesn't automatically check procedural controls that require manual evidence collection.
You can find this framework under the Standard frameworks tab of the framework library in Audit Manager.
