Ensuring appropriate management and protection of information assets

Our policy

The evolution of IT poses multiple threats to system security, so we have to recognize that it could risk influencing our business management and take appropriate and timely measures. To earn the trust of our customers and society at large, we are developing information security across the Group that will protect our information assets from the threat of accidents, disasters and crime.

We have established a secure environment to protect Group information assets from security risks. To be ready for ever-evolving security issues, we need to conduct investigations into future risks and introduce new technologies. Damage caused by information leaks and external attacks can include leakage of business partners’ personal data, suspension of production lines and other severe impacts on business continuity.
At Toyo Tire Corporation, we hold practice drills for employees on targeted email attacks and conduct regular security checks.
In 2022, we held two email practice drills for 3,727 employees. We are conducting security-related education for those who mistakenly opened the emails in order to prevent reoccurrence. As part of our recent measures against malware, we are also building email solutions with features such as suspicious link removal to reduce the risk of information leaks.
