Abstract
Cyberattacks have recently been on the rise. The increasing sophistication and complexity of cyberattacks has made it difficult to prevent such attacks from occurring. Therefore, it must be important to formulate appropriate incident responses to cyberattacks limit their damage. As seen in the case of the Japan Pension Service, where damage is increased due to a lack of communication during the response to cyber incidents, good internal communication practices is essential to ensure an appropriate incident response. To minimize the impact of cyberattacks, this study constructs a hierarchical structure model using interpretive structural modeling. The results reveal that the degree of dependency that the variables have over each another according to the cross-impact matrix multiplication applied to classification analysis regarding effective intraorganizational communications during a cyberattack response. In addition, based on these results, a use case of the results will be proposed to design more effective intraorganizational communications when responding to a cyberattack.
