NIST SP 800-171

NIST SP 800-171 is a set of guidelines created by the National Institute of Standards and Technology to help organizations protect sensitive information, specifically Controlled Unclassified Information (CUI), when it is stored or processed in non-federal systems. It outlines 14 families of security requirements, including access controls, incident response, and risk assessment. Organizations, particularly those working with the government or defense sectors, use these guidelines to ensure that they have effective security practices in place, maintain data privacy, and mitigate risks to sensitive information from potential threats or breaches.
