DIB

The network of private and public organizations that research, design, produce, deliver, and maintain the systems, services, and technologies used by the U.S. Department of Defense (DoD) to support national security and military operations. It encompasses a vast ecosystem of manufacturers, suppliers, academic institutions, and contractors that provide a range of services, from advanced weapon systems and software to logistics, maintenance, and infrastructure support.

The DIB includes both large defense contractors and small to medium-sized businesses that form the supply chain for critical defense projects. Due to the sensitivity of the work performed in this sector, the DoD requires DIB participants to adhere to strict cybersecurity and compliance standards, particularly those outlined in frameworks such as NIST SP 800-171 and the Cybersecurity Maturity Model Certification (CMMC).

A secure and resilient Defense Industrial Base is vital for ensuring that the U.S. military maintains technological superiority and operational readiness. The DoD collaborates closely with industry partners through programs such as the DIB Cybersecurity Program, which facilitates threat information sharing and incident reporting.

Ultimately, the DIB is not just an industrial sector; it is a strategic national asset. Its protection from espionage, cyberattacks, and supply chain vulnerabilities directly underpins the security, innovation, and global effectiveness of the United States’ defense enterprise.
