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.

  • 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.

Conflicting Interests

All business decisions made by the NGK Group are made fairly and appropriately in anticipation of the best interests of the Group. All persons engaged in the NGK Group's business will, with a high sense of ethics, pay close attention to their interactions with current and future customers, suppliers, subcontractors, competitors, and other third parties, and respond in good faith, avoiding the construction of situations or relationships that may lead to conflicts of interest as a result of non-business relationships with other companies or individuals.

Based on this philosophy, NGK Group will continue to manage situations that may cause conflicting interests;
for example, an employee has a close personal interest in the business of third parties relevant to NGK Group, employs or manages relatives or close friends for lucrative positions, or uses company resources for private endeavors. We have been establishing management system to take necessary measures in a timely manner.
