Enterprise Risk Management

UMC is well aware that Cyberattacks may not only expose the Company to the risks of data leakage and ransom threats, but also interrupt the production system, causing serious operating losses or even damaging the reputation of the Company. Facing the ever-changing and diverse external threats, it is critical to strengthen corporate information security. Correctly responding to the changing environment with limited resources is an important task.

“Enterprise Information Security Committee” is responsible for information security management system planning, establishing and maintenance. Senior Vice President TS Wu managing the Digital Function serves as the Chief Information Security Officer (CISO), who is responsible for establishing and maintaining the information security strategy and processes that protect information assets.

Board level “Sustainable Development and Nominating Committee” is dedicated to oversee information security-related matters, coordinate overall development of information security strategies, risk management, and operational execution. All members of this committee are independent board directors, with the convener being Independent Board Director Jyuo-Min Shyu, who has relevant experience and professional background in cybersecurity. Mr. Shyu was the Minister of the Ministry of Science and Technology and the President of Cloud Computing & IoT Association in Taiwan, and led multiple information security projects such as the National Information & Communication Security Taskforce as Vice Chairperson and the IoT Information Security SIG (Special Interest Group) initiative.

To effectively address the constantly evolving threats to information security, UMC has established and implemented the following policies to create a secure digital environment and comprehensively safeguard the Company's information security.
