Frequently Asked Questions

Plain answers to the questions we hear most often from contractors.

  • NIST SP 800-171 is a set of security requirements from the National Institute of Standards and Technology for protecting Controlled Unclassified Information (CUI) in non-federal systems. Contractors that handle CUI for the Department of War are generally required to implement it.

  • NIST SP 800-171 is the baseline for protecting CUI. NIST SP 800-172 adds enhanced requirements for CUI tied to critical programs or high-value assets, aimed at defending against advanced persistent threats.

  • The Cybersecurity Maturity Model Certification (CMMC) program verifies that contractors have implemented required security practices. CMMC Level 2 is built on the NIST SP 800-171 requirements, and Level 3 adds requirements drawn from NIST SP 800-172.

  • The Enterprise Mission Assurance Support Service (eMASS) is the DoW’s web-based system for managing cybersecurity authorization packages under the Risk Management Framework (RMF). We help teams build, organize, and maintain those packages.

  • Both. Physical security assessments are performed on-site. Training, compliance support, and many assessment activities can be delivered virtually.
