In order to promote CMMC, the U.S. government has aligned a single goal of federal administration and legislatives. Starting with the President's announcement of the National Cyber Strategy, passing of various authorization bills by the Congress, clear division of work responsibilities for different departments and agencies, issuances of cybersecurity standards, reviewing and revision of related regulations, and intensive communication with the defense industry, culminating in the Department of Defense's formulation of a brand new framework and execution plan. It's overall implementation experience and progress is truly a worthy of lesson learned to us. However, the scale of the defense supply chain in Taiwan is far from the vast of defense industrial base in the United States. Therefore, in practice, it is necessary to think a collaboratively way for integrating government and private sector's resources, utilizing cost-effective approaches, overcoming various obsobstacles and establishing a constructive mechanism that can well meet the national cybersecurity needs of Taiwan. This requires collective brainstorming and exploration.
