It is a total risk management system that encompasses not only computer system security measures but also basic policies for handling information (security policy), specific plans based on this security policy, implementation and operation of those plans, and periodic review of policies and plans. ISMSs are standardized by the ISO/IEC 27001 (in Japan, JIS Q 27001) specifications. Third-party verification of an ISMS’s compliance with the requirements set forth by these standards is called ISMS certification.


ISO stands for International Organization for Standardization and is also used as a general term for international standards published by this organization. ISO 13485 is a standard that specifies requirements for quality management of medical devices. While ISO 9001 stipulates organizational policies on the quality and services a company offers to customers and a mechanism for constantly improving quality and services to meet customer expectations, ISO 13485 applies specifically to medical devices, which exert a significant impact on human life and the maintenance of health. For this reason, ISO 13485 incorporates particular requirements for medical devices on top of the basic requirements specified by ISO 9001. Quality management systems for medical devices can be third-party certified.
