Roles and Responsibilities

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 management organization (As of April 1, 2023)


TDK is strengthening its information security measures in accordance with the Cybersecurity Framework of the US National Institute of Standards and Technology (NIST) ((1)identify, (2)protect, (3)detect, (4)respond, (5)recover), which can be described as the standard for information security countermeasures.

[Principal Measures]

  • Use of a mechanism to automatically evaluate security administration conditions and identify and improve vulnerabilities ((1)identify, (2)protect, (3)detect)
  • Support for improvements after confirmation of supply-chain security conditions ((1)identify, (2)protect)
  • Introduction of mechanism to detect the status of use of dangerous cloud services ((3)detect)
  • Global implementation of training to counter security incidents ((4)respond, (5)recover)
  • Global subscription to cyber-risk insurance ((5)recover)
  • In order to respond to cyberattacks, which are becoming an increasingly serious threat, TDK is strengthening countermeasures to prevent the occurrence of damage and, in the event that damage does occur, to minimize it.
    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.

Information Security Education

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 the content and frequency of the education, each site incorporates appropriate topics in accordance with its environment and circumstances.
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.

Filing of Complaints Regarding Privacy Violations

TDK has formulated the Basic Policy on the Protection of Personal Information and endeavors to manage personal information properly. In fiscal 2023 there were no reports or receipt of complaints in Group companies concerning the infringement of customer privacy or the loss of customer data.
