As cybersecurity becomes a challenge that includes supply chains, sophisticated cyber-attacks and state-sponsored actors have become a serious threat. Combined with the evolution of IoT and DX, we have entered an era where conventional defense measures are insufficient. This session presents the transformation brought about by the fusion of platform strategy and AI to address this current situation. We will explain real-time threat analysis using AI and the platformization of security. Furthermore, we will introduce the evolution of network security including IoT, and the streamlining of operations incorporating generative AI. We will explain the next-generation security approach in an easy-to-understand manner and provide practical insights for renewing corporate security strategies.
