With advances in generative AI and advanced analytics, we are entering an era where vulnerabilities in automotive systems are being discovered at a faster pace and on a larger scale than ever before. Meanwhile, while the automotive industry is making progress in secure development and proactive vulnerability detection using AI, ensuring the long-term security of vehicles already on the market has emerged as a new challenge. In this session, we will discuss with panelists the systems required and the ideal future state of the industry to “continue protecting vehicles after they are sold,” focusing on vulnerability management in the AI era, P-SIRT operations, OTA-based countermeasures, and the use of vehicle monitoring.
