The DRC of the Ministry XYZ has suffered from a system breach. The DRC's problem will lead to a lack of system information security, availability, and an increasing threat to the whole system of Ministry XYZ. In 2019, the KAMI Index assessment of the Ministry XYZ stated that the level of maturity and completeness of the application of ISO 27001 standards of the XYZ Ministry were at the level of fulfillment of the basic framework. There is a gap between the assessment result and the operational problem within the DRC of Ministry XYZ due to the lack of an information security management system. Therefore, this study conducts the same KAMI Index assessment within the scope of the DRC only and aims to offer a recommendation based on ISO 27001 as the basis of the KAMI Index assessment. This study used discussion, observation, and KAMI Index assessment tools for collecting data and analyze the result. The assessment result of the DRC showed that the maturity level of the ISO 27001 standard on the DRC is on the application of the basic framework. The suggested recommendations to improve the information security management system of the DRC were mostly in the aspect of the information security framework and assets management.
