The Defense Industrial Base (DIB) refers to the network of private sector companies and organizations that provide products, services, and research to support national defense and military operations. These entities supply the Department of Defense (DoD) with essential technologies, systems, and materials, ranging from weapons and vehicles to IT services and logistics. The DIB is a critical component of national security, and its protection from cyber threats is a top priority. Cybersecurity measures are implemented across the DIB to safeguard sensitive information, maintain operational readiness, and ensure the integrity of defense supply chains against espionage, sabotage, and other cyber risks.
