NIST SP 800-171 Quick Entry Guide_PIEE-SPRS.pdf

The document is a NIST SP 800-171 Quick Entry Guide for the Supplier Performance Risk System (SPRS), Version 4.0, designed to help users navigate the cyber vendor assessment process. The guide provides step-by-step instructions for accessing the PIEE (Procurement Integrated Enterprise Environment) system, selecting the SPRS module, and entering NIST SP 800-171 cybersecurity assessments. Key steps include selecting the appropriate CAGE (Commercial and Government Entity) hierarchy, adding new assessments, and entering assessment details such as assessment date, score, scope, and system security plan information. The guide emphasizes that the Basic Confidence Level assessment is the only one that can be maintained by vendors, and assessments turn red when they expand beyond three years.
