Mini Special Issue on Cyber Security

抄録

As our daily lives and socioeconomic activities have increasingly come to depend on information systems and networks, the impact of disruptions to these systems and networks have also become more complex and diversified.

In urban areas, where people, goods, money, and information are highly concentrated, the possibility of chain failures and confusion beyond our expectations and experience is especially high.

The vulnerabilities in our systems and networks on have become the targets of cyber attacks, which have come to cause socioeconomic problems with increasing likelihood. To counter these attacks, technological countermeasures alone are insufficient, and countermeasures such as the development of professional skills and organizational response capabilities as well as the implementation of cyber security schemes based on public-private partnerships (PPP) at the national level must be carried out as soon as possible.

In this JDR mini special issue on Cyber Security, I have tried to expand the scope of traditional cyber security discussions with mainly technological aspects. I have also succeeded in including non-technological aspects to provide feasible measures that will help us to prepare for, respond to, and recover from socioeconomic damage caused by advancing cyber attacks.

Finally, I am truly grateful for the authors’ insightful contributions and the referees’ acute professional advice, which together make this JDR mini special issue a valuable contribution to making our society more resilient to incoming cyber attacks.
