Abstract
IEEE 802.1 Time-sensitive Networking (TSN) standards are envisioned to be the backbone of mission-critical networks in the near future. Such networks have strict latency and reliability requirements, and any missed deadline for critical services may have hazardous consequences. Low-latency and deterministic communication scheme in TSN makes the network potentially susceptive for various attacks. Therefore, protecting time-sensitive networks against security threats is a crucial design concern. In this paper, we discuss more than 30 potential security issues and threats of IEEE 802.1 TSN protocols. Our goal is to explore attack surfaces on such systems to be more extensively analyzed and eventually protected.
