National security mechanism involves autonomous functions with different administrative organizations. Policymakers strive for the strategic opportunities in order to seek long-term national development under different terms of time and space. Our national security affairs deal with national defense, diplomacy, cross-strait relations and relative events including significant, unexpected national incidents. The general strategic aims of national security are to ensure sovereign dignity, living safety and prosperous development of the nation and freeing the nation from the threats, infringements and destructions from domestic or abroad.

These changes have influence on the progresses of national security laws, organizations, functions, operations and whether the principle of our national security policy could cope with challenges effectively.
