Definition
NIST SP 800-171 is a set of security requirements designed to protect Controlled Unclassified Information (CUI) when it is handled by non-federal organizations. It outlines specific security controls that contractors and other entities must implement to safeguard sensitive federal data. These controls cover areas such as access control, configuration management, incident response, and system monitoring. Implementing NIST SP 800-171 ensures that organizations handling CUI maintain a robust cybersecurity posture, preventing data breaches and unauthorized access. For example, a defense contractor must ensure their systems meet these standards before being awarded a contract that involves access to CUI. This differs from general cybersecurity frameworks by its specific focus on CUI protection for federal contractors. Knowledge of NIST SP 800-171 is often tested in cybersecurity certifications like CompTIA Security+ and CISSP.
