Different types of risks vary depending on business characteristics of enterprises. Because environments such as politics and management environments, social hangings, and consumers tend to differ, they must understand the environment in which they are placed. Based on this, a methodology for assessing the risk of disaster risk will be needed for the organization's situation. Businesses should have a framework to carry out continuous operations in case of disasters. In order to do so, it is necessary to establish measures, recognize risks, and evaluate them. Disaster risk management is meaningful to minimize the damage to the business, minimize the disruption of the business, and protect the assets and people, and maintain sustainable businesses, including disaster prevention activities.
