Description:
NIST 800-171 is a framework that specifies how your information systems and policies need to be setup in order to protect Controlled Unclassified Information (CUI).
Essentially, NIST 800-171 is a set of standards that define how to safeguard and distribute material deemed sensitive but not classified. NIST 800-171 was developed after the FISMA (Federal Information Security Management Act) was passed in 2003, resulting in several security standards and guidelines.
