Improvement of the Defense Planning and Management System to Implement the ROK’s National Cybersecurity Strategy

With the development of the Internet, cyberspace has expanded, which has ushered in several changes. These changes have significantly impacted the defense sector. The defense sector is changing from an existing weapon system-centered operation to a network-centered operation, and cyberspace is now recognized as the fifth strategic space, land, sea, air, and space. However, this expansion of cyberspace paradoxically increases its vulnerability to cyberattacks. Hacking groups have been causing damage through cyberattacks in many countries. Therefore, several countries are preparing countermeasures for cybersecurity at the national level. In 2019, the ROK announced its national cybersecurity strategy. However, in the case of the defense field, there are limitations in implementing the cybersecurity policy of the higher concept because it is closed and has specificity. Accordingly, this paper proposes the secure defense planning and management system (SPPBEES) so that the cybersecurity policy of the high concept is materialized as a strategy and leads to force reinforcement.
