Cyber Security Rating Framework and its Application to J1939-1C Standard Present day automotives are becoming smart and more software driven. Conversely every line of code equals to a possible threat to the vehicle, passenger as well as the OEM. To hit the brakes on the alarming increase in cyber-threats, Government bodies have introduced standards and regulations globally. UNECE's WP.29 R155 & R156 regulations and ISO/SAE 21434 standards are mandatory for all OEMS. However, the gap is a framework and a standard that provides guidance and common criteria for automakers to measure the vehicle's level of compliance and compute a publicly accepted cyber security rating. This paper addresses the above requirement and discusses the Cyber Security Rating Framework (CSRF) that establishes a standard for rating vehicle cyber security by standardizing the measurement criteria, parameter vectors, process and tools.
