CSR – Framework and Guidelines

Framework and Guidelines

The President & CEO assigns a Corporate Manager for Confidential Corporate Information Management and Personal Information Protection and an Audit Manager for Personal Information Protection. The Corporate Manager assumes overall responsibility for information security, and the Corporate Secretariat for Confidential Corporate Information Management and Personal Information Protection is in charge of planning and promoting information security measures. Responsibility for the actual utilization and management of confidential corporate information and personal information lies with the general manager of each business group (Confidential Corporate Information Management and Personal Information Protection Managers) and the manager of each business site (office directors, etc.). The Business Group Secretariat and Business Office Secretariat strive to ensure information security by maintaining close coordination and regularly holding meetings with the Confidential Corporate Information Management and Personal Information Protection Secretariat.

The Audit Manager is responsible for implementing and reporting the results of personal information protection audits. In the incident of a leakage of confidential corporate information or personal information or in any other information security incident within the Mitsubishi Electric Group, the matter is reported to the leader through the framework, where it is promptly dealt with in compliance with relevant laws and regulations and is disclosed as necessary in a timely and appropriate manner.

Business Groups also issue instructions and guidance to overseas affiliates in the same way as they do to domestic affiliates, and strive to ensure information security in cooperation with overseas regional offices.

The Mitsubishi Electric Group learned a bitter lesson from an accident that occurred in 2010 involving a leak of personal information collected from customers. Based on this experience, it is taking every step to ensure that no leakage of confidential corporate or personal information, or no similar accident, occurs again.
