Defense Industrial Base (DIB)

The Defense Industrial Base (DIB) is the worldwide industrial complex that enables research and development, design, production, delivery, and maintenance of military weapons systems, subsystems, and components. It includes over 300,000 companies ? from major defense primes to small machine shops ? that contribute to the DoD's supply chain.

The DIB is a high-value target for nation-state cyber actors because it holds critical technology, military intelligence, and sensitive information. CMMC was established to raise the cybersecurity baseline across this ecosystem.

Why It Matters

Organizations in the DIB face persistent targeting from sophisticated threat actors. Understanding this threat landscape provides context for why comprehensive security controls are emphasized across the defense supply chain.
