CISO Message

KDDI CORPORATION
Senior Managing Executive Officer
CTO, Executive Director, Core Technology Sector
Kazuyuki Yoshimura

As KDDI VISION 2030, KDDI delivers the message, "Evolving the "capacity to connect" to create a society where anyone can achieve their wishes" and is working on a diverse range of businesses to achieve a fruitful communication society. Information security is key in this pursuit. As the responsibility of an enterprise that plays a role in core infrastructure, KDDI positions information security as a critical issue for delivering stable telecommunications services at all times.
The proliferation of smartphones, the development of big data and AI technologies, and the corporate progress in digital transformation have led to the creation of new services using various information, which also comes with intricate and diversified risks in information security and privacy. Cyber-attacks and other criminal activities in cyberspace by malicious hacker groups are increasing and getting more and more sophisticated.
Amid such circumstances, in order to protect telecommunications facilities from unauthorized access, tampering, targeted attacks, and other cyber-attack threats, KDDI's security engineers are on vigilant duty round-the-clock for monitoring while we are simultaneously developing automated AI-driven technologies for analyzing and monitoring cyber-attacks. Furthermore, KDDI regularly works in collaboration with CSIRTs in Japan and abroad, as well as other relevant organizations, to collect and analyze vulnerability information and attack trends to set up stronger security measures.
KDDI will continue to provide services that users can rely on as being safe by keeping up the development of our combat against increasingly sophisticated and complex emerging threats. This website introduces KDDI's security initiatives. We appreciate your interest and time in reading through this website.
