Basic NGK Group Information Security Policy

As our information-communication society grows ever more sophisticated, the NGK Group has come to handle much more in the way of information assets, and is aggressively pursuing the safekeeping of any and all information assets it retains. While it is essential to share these assets in order to conduct business in a smooth and efficient manner, establishing a system for information security likewise becomes a necessity. For this reason, the NGK group has set forth this basic policy regarding information security and will work to safeguard the information assets in its possession.

  • In order to ensure the safety of retained information assets, which includes information retained in the course of business activities, as well as any devices, facilities, or services necessary to handle said information, we will establish an information security management system to prevent unauthorized intrusion, loss, theft, leaks, modification, damage, denial-of-service attacks, and any other threat.
  • All individuals who work at any office of NGK or its group companies and who make use of information assets will be subject to ongoing information security education and training for an increased awareness of security issues. Actions in violation of this Policy may be subject to legal penalties, as well as reprimands set forth in labor regulations, contracts, and/or other binding documents.
  • Should a security issue arise concerning information assets, we will promptly investigate the cause and work to keep any damage to a minimum.
  • We will comply with all laws and social norms with regard to information security, as well as any such contractual requirements and duties entered into with a customer.
  • NGK will strive to continuously review and revise the activities noted herein.
