Information Security

The Yokogawa Group works together with customers to provide them with solutions. To protect important information entrusted to us by our stakeholders, we implement information security measures to address three aspects: people, equipment, and information technology (IT).

An important way to protect information is to raise the security awareness of each employee by training them on how to handle information. To ensure that Yokogawa’s employees appreciate on the importance of information security and keep their knowledge up to date, the Yokogawa Group uses an e-learning system to annually provide training to all employees. Based on the belief that “a good beginning makes a good ending,” the Group provides training to new employees who are entering straight out of university or in mid-career to familiarize them with the rules of their new workplace. We also review the details and results of the training through information security audits.

We implement anti -theft, fire-prevention, and other security measures to protect locations where information is stored. Our facilities and equipment are kept under continual surveillance, and efforts are made to replace obsolete facilities and equipment with state-of-the-art ones. For R&D facilities that require advanced security, we implement a variety of security measures including the introduction of iris authentication for facility access control and the use of storage cabinets that can only be unlocked with an employee ID card.

The most vulnerable point with regards to information security breaches is people. People can leak information by mistake and misuse information out of ignorance. IT systems provide ways to prevent such human errors.

1. Measures to prevent data leakage from PCs
   We create a more secure environment by installing antivirus software, implementing biometric authentication, using data encryption, and more.
2. Anti-spam measures
   We have implemented an anti-spam filtering system, because spam mail is not only bothersome but also includes malicious mail that may cause data leakage and virus infection.
3. Network connection device management
   To protect against unauthorized access and data leakage, we prevent unregistered PCs and related devices from being connected to the network.

There is an Information Security Management Committee that discusses and determines information security measures and policies. In addition, there is an information security department or section for each of the Yokogawa Group’ s headquarters and business headquarters, as well as for each Group company. A PDCA, or Plan-Do-Check-Act, cycle is implemented to ensure information security activities are implemented smoothly.
