Explore an innovative Intrusion Detection System (IDS) called Scission in this 23-minute conference talk presented at the Association for Computing Machinery (ACM). Dive into the world of automotive cybersecurity, focusing on the vulnerabilities of the CAN bus and how Scission addresses the critical issue of sender authentication. Learn about the system's methodology, including sampling, preprocessing, model generation, and classification techniques used to extract fingerprints from CAN frames for identifying sending ECUs. Examine the evaluation process, stability considerations, and intrusion reaction mechanisms. Gain valuable insights into this cutting-edge approach to enhancing vehicle security and protecting against potential cyber attacks on connected ECUs.
