DIB

The Defense Industrial Base (DIB) refers to a global network of private-sector companies and organizations that provide products and services to the Department of Defense (DoD) and other defense-related government entities. These companies design, develop, manufacture, and maintain military systems, equipment, and technologies that are critical for national defense and security.

The DIB includes a wide range of industries, such as:

Aerospace and aviation
Shipbuilding
Information technology
Cybersecurity
Defense electronics
Weapons and munitions manufacturing
Maintenance and repair services

Companies within the Defense Industrial Base vary in size from small businesses to large multinational corporations, and they play a vital role in supporting the U.S. military by supplying everything from raw materials to highly sophisticated weapon systems.

A key focus of the DIB is safeguarding sensitive data, such as Controlled Unclassified Information (CUI), and ensuring strong cybersecurity practices to protect against threats that could compromise national security, which is a major aspect of compliance with frameworks like CMMC (Cybersecurity Maturity Model Certification).
