Hitachi High-Technologies GLOBAL

To prevent the leakage or divulgence of information that is important to companies, such as business, technological information, and personal information, whether in digital or paper form, the Hitachi High-Tech Group has implemented a range of measures and is working to strengthen information security.

Policy

As the Group is aware that efforts to maintain information security are a high priority, we have developed regulations and organizations to facilitate such efforts, as well as ensuring awareness among all employees. The Information Security Committee was established as an organization to promote information security management systems. It is conducting a range of activities in accordance with the "3 Principles to Prevent Leakage of Confidential Information" as a united company, from management through to regular employees.

Three Principles to Prevent Leakage of Confidential Information

  1. As a rule, it is forbidden to take confidential information outside the company.
  2. Approval must always be given by a superior before confidential information is taken outside the company due to business necessity.
  3. If confidential information is taken outside the company due to business necessity, measures must be implemented to avoid leakage of information.

System

Information Security System

The Information Security Committee was established as an organization to control information security of the whole company under the direction of the Information Security Administrator appointed by the President and Chief Executive Officer. In addition, under the direction of each manager, we are expanding security incident responses, alerts, and security strengthening measures throughout the company and Group.
