This committee is established as a subordinate organization of the EHSS General Committee*1, in which directors with executive authority and divisional managers participate, and is responsible for the appropriate management of information security risks, cyber security risks, and IT governance risks in ROHM Group.
Information Management Committee is chaired by the corporate officer, and its subordinate organizations are the Confidential Information Management Committee, the Information Security Management System (ISMS) Committee, the Cyber Security Committee, and the IT Promotion Committee. Each committee formulates goals, implements measures, and conducts evaluations for each theme, and reports progress and results to the Information Management Committee on a regular basis. In addition, the EHSS General Committee has established a system to evaluate and confirm whether the PDCA cycle of the Information Management Committee is being properly implemented, and to maintain and improve the accuracy of the management system.

ROHM Co., Ltd. and LAPIS Semiconductor Co., Ltd. have acquired ISO/IEC 27001 certification, an information security management system certification, and the scope of application includes planning, development, maintenance, and operation of the ROHM Group's internal information systems, as well as planning, development, manufacturing, and sales of SiC and other products.

Information Security Activities

Proper management of information about stakeholders, as well as information held by ROHM Group, is essential for providing better products and services to society and for reliable corporate management.
ROHM Group is promoting information security measures through the following continuous efforts. In the unlikely event of an accident, we will immediately investigate the cause and take appropriate measures including recurrence prevention measures.

IT Assets Management

ROHM strictly manages its IT assets by centralizing the purchase and disposal of IT assets (PC terminals, software, USB memories and other storage media, and internal communication devices), monitoring usage with an IT asset management tool, and taking monthly inventories. Through these efforts, we prevent and manage compliance and security risks such as illegal use of IT assets, cyber attacks, and security breaches.

Enforcement of IT Asset Management

Kitting : Setting up PCs and installing software to make them usable for business

Security Measures for Information Devices

We have implemented anti-virus and Windows vulnerability countermeasures for PCs and other information devices used by employees. Furthermore, we have constructed and been maintaining an environment where information leakage does not occur by introducing multi-factor authentication and mechanisms to remotely perform a factory reset of a computer in case of loss.

In response to the recent increase in the risk of cyber attacks, ROHM has established a system in which computers used by employees are monitored 24 hours a day, 365 days a year by an external specialized organization for signs of cyber attacks, to detect and respond to threats as early as possible.

Enforcement of IT Asset Management

Education and Training

Many of the causes of information leakage are mishandling, mismanagement of devices and information, and lack of awareness of information security, all of which correspond to human error.
In order to prevent and reduce security risks caused by humans, ROHM requires employees to sing an information security-related pledge when they join the company to make their responsibilities for information clear, and also continuously provides them with training and education to improve their security literacy.
