Under the Executive Committee, TDK has set up the Information Security Committee, which adopts measures in response to information security risks in the Group as a whole. By establishing deliberative bodies made up of representatives from each region around the world, we are reinforcing global information security governance. Through the Information Security Administration Managers Meeting and other channels, the Information Security Committee endeavors to implement measures for each division.

Information Security Education

In order to maintain and enhance information security throughout the entire TDK Group, we implement information security education and email training for all employees more than once a year.
Information security education is conducted at Group sites for computer users. Regarding content of the education and frequency, each site incorporates appropriate content in accordance with its environment and conditions.
In the email training at each site, emails resembling actual targeted email attacks are sent to employees to check the number of people who open the attached file and the number of people who click on the URL.

Future Activities

In order to respond to cyberattacks, which are becoming an increasingly serious threat, TDK will reinforce internal information security countermeasures and strengthen measures regarding cloud services, use of which is increasing, on a global level.
In addition, TDK will continue to enhance employee education and training, including training to handle targeted email attacks, thereby responding to risks in the Group as a whole that cannot be fully handled by the system.
