Cybersecurity & Data Compliance for Subcontractors

Subcontractors handling covered defense information are required to implement all NIST SP 800-171 security controls to protect the confidentiality, integrity, and availability of sensitive data. This includes establishing robust access controls, continuous monitoring, incident response plans, and secure configuration of systems and software. Compliance with these controls is mandatory and must be verified through documented policies, employee training, and regular assessments. In addition to control implementation, subcontractors must establish and maintain procedures for prompt cyber incident reporting, including immediate notification to the Department of Defense upon detection of any security breach or suspicious activity involving covered defense information. The requirement extends to all systems and networks that process, store, or transmit such data, regardless of location or ownership. Failure to comply may result in contract termination, financial penalties, or loss of eligibility for future defense-related work. This obligation is tied to the Defense Logistics Agency’s oversight under the Department of Defense and applies to all subcontractors engaged in activities supporting defense contracts under NAICS code 541512.
