The present document summarizes the results of a Threat@ Vulnerability and Risk Analysis (TVRA) of 5@9 GHz radio communications in an Intelligent Transport System (ITS). The analysis considers vehicle-to-vehicle and vehicle-to-roadside network infrastructure communications services in the ITS Basic Set of Applications (BSA) [i.3] operating in a fully deployed ITS. The present document was prepared using the TVRA method described in ETSI TS 102 165-1 [i.1]. NOTE: Whilst the present document is a technical report it identifies requirements for future work. In all cases these requirements are considered indicative pending their ratification in formal ETSI Technical Specifications within the ETSI ITS Work Programme
