Basic Concept
The Nisshinbo Group regards information security as one of the most important risks, and in April 2023, the Group revised the "Guidelines for Information Security" to be achieved by the Group and deployed them to group companies to improve information security and establish an information security operation system. These guidelines consist of human and organizational management, physical management, and technical management, and the following three points were particularly emphasized in the revision.
- ① When outsourcing operations, the responsibilities of the outsourcer regarding information security and the measures to be implemented should be clarified.
- ② In preparation for the event of an information security incident, an emergency response system and recovery procedures should be established.
- ③ For backups of important information, backups should be stored in a secure environment and restoration procedures should be established.
In addition, The Group recognizes that one of its key corporate responsibilities is to ensure that all important information related to stakeholders is protected and managed appropriately. In order to fulfill this responsibility, the Group handles personal information in accordance with its "Privacy Policy."

Cyber Security Framework

Initiatives to Ensure Information Security
The Nisshinbo Group has established the "Guidelines for Information Security" to set forth rules to be followed by all group companies in Japan and overseas. To prevent the leakage of confidential information, including customers' personal information, the Group is continuously promoting education and other measures to enhance information security based on these guidelines.

Compliance with Rules / Implementation of Information Security Education and IT Internal Audits
The Group has compiled rules to be kept by information system users into educational materials and is working to raise awareness of information security measures among all Group users through a Learning Management System that includes periodic education and comprehension tests. At the same time, group training is provided for new employees and those dispatched overseas.
In addition, IT internal audits are regularly conducted on Japan and overseas subsidiaries to confirm compliance with the information security guidelines and to ensure continuous improvement.
Prevention of Internal Fraud
The Group uses an information security management system to monitor access to important data and restrict network access to unauthorized information devices.
Prevention of External Attacks
To counter cyber-attacks, the Group monitors e-mails through its e-mail security system, installs antivirus software on information equipment, and applies security correction programs thoroughly.
Targeted e-mail drills are conducted once a year for employees of domestic and overseas Group companies with the aim of raising cyber security awareness and cultivating response capabilities. In the FY2024 training, training e-mails simulating three targeted e-mail drills were prepared for 8,097 participants from 31 Group companies and sent to the targets at random. The open rate varies greatly depending on the pattern of training e-mails, and the Group will use this as an opportunity to identify future issues, enhance security education, and continue targeted e-mail training.

Countermeasures in the Event of a Large-Scale Disaster
From the standpoint of business continuity in the event of a large-scale disaster, the Group promotes the use of external data centers and cloud systems.
Support for New Normal Lifestyles
To enhance security during telework, the Group eliminated traditional VPN connections and switched to using a cloud-based firewall system. The group is moving from a traditional perimeter security model that keeps the company secure internally to a zero trust security model that monitors the overall status with the same security from outside the group.
Initiatives to Protect Personal Information
To ensure every one of its employees maintains awareness of personal information protection, the Nisshinbo Group conducts training when employees join the company and when they are promoted as well as training at each of its business sites based on its annual plan. The Group also conducts regular internal audits to check the management status of listed personal information (registration, deletion, storage methods, training status, etc.), and is committed to thorough and continuous improvement in preventing external leakage.
Initiatives Related to Generative AI
Generative AI services available to the public are useful for improving operational efficiency and generating new ideas, but concerns about authenticity and copyrights, as well as the risk of leaking confidential information, have also been raised. Therefore, guidelines for the use of generated AI were established in July 2023, and deployed to Group companies. Each company will tune and customize the guidelines to optimize them for their own needs and prohibitions and to ensure appropriate use and management.
Specific Activities of the Group Companies
Preparation for Information Security Incidents
