Printers, copiers, scanners, monitors, and shared workspaces can all become physical CUI exposure points if they are not properly controlled. NIST SP 800-171 Rev. 3 explicitly requires organizations to restrict physical access to output devices so unauthorized individuals cannot obtain Controlled Unclassified Information. This article breaks down what that means in practice, why shared office equipment creates real compliance risk, and how physical safeguards like coversheets, signs, labels, and controlled workspaces help protect CUI during everyday handling.
