Information Security
Approach to Information Security
An environment where data can be used safely and securely is crucial for the continuous and steady development of the operations of the Company. For this reason, we view the assurance of information security as an important managerial issue, and continuously reinforce the protection of information about our customers and suppliers as well as confidential information on leading-edge technology. In addition, we strive to strengthen information security to ensure the stable operation of the entire supply chain.
TEL Group Information Security Policy
July 1, 2020 Established
June 1, 2026 Revised
- Introduction
- As society becomes increasingly reliant on information, information security risks continue to grow. Organizations are therefore required to effectively manage, protect, and utilize information. The TEL Group recognizes that ensuring the confidentiality and integrity of information, as well as the availability of systems that support its business operations, is essential. We are committed to identifying and assessing risks and ensuring information security.
This policy sets forth the fundamental principles of information security that guide the TEL Group’s business activities.
- TEL Group Information Security Goals
- Protect and properly manage confidential information to prevent data leakage and enhance customer satisfaction
- Prevent unauthorized alteration of information assets and ensure that business is conducted based on accurate information
- Strengthen resilience against incidents to ensure business continuity
- Comply with applicable laws, social norms, and the ethical standards, and fulfill the social responsibilities
- Achieve both digital transformation (DX) and security in a balanced manner
Maintain the confidentiality, integrity, and availability of all information assets necessary for business, including the environments in which they are processed (collectively, “information assets”), to enhance the corporate value of the TEL Group.
Implement the following measures to achieve this:
- Primary Objectives
- Appoint a Chairperson of the Information Security Committee to oversee information security across the TEL Group, establish a globally unified information security strategy, and ensure the implementation of necessary measures throughout the TEL Group
- Establish common information security rules in compliance with applicable laws and international standards, provide training to raise awareness and ensure adherence to these rules, and maintain appropriate information management across the TEL Group
- Continuously monitor and detect security threats, and continuously improve information security through the PDCA (Plan-Do-Check-Act) cycle
- Ensure information security across the entire supply chain
- Establish a unified incident response process across the TEL Group, and enhance response capabilities through continuous training
- *Confidentiality: Information assets can only be accessed by authorized persons.
*Integrity: Information assets are maintained in an accurate state without unauthorized alteration or error.
*Availability: Information assets are available to authorized personnel whenever needed.
