Threat Analysis and Risk Assessment for Connected Vehicles: A Survey

With the rapid development of connected vehicles, people can get a better driving experience. However, interconnection with external network may bring growing accidents caused by cybersecurity vulnerabilities. As result, automakers are paying more attention to and spending cost on developing defense mechanisms. Threat analysis risk assessment (TARA) is an efficient method ensure effect greatly save costs in early stage vehicle development. It analyzes threat systems determines hierarchical corresponding mitigations according potential system. This paper gives overview automotive field. First, novel classification different TARA methods has been proposed. The existing have analyzed compared. Then, we found some commonly used tools applied compared their performance. After that, concept named attack-defense mapping proposed figure out how map already threats vulnerabilities system appropriate mitigations. At last, future directions domain discussed.
