Connected vehicles (CVs) and autonomous vehicles (AVs) are transforming global transportation. While business leaders enthuse about reinventing the in-vehicle customer experience to drive brand loyalty and differentiation, security and risk (S&R) pros struggle to secure and protect the complex vehicle infrastructure. Insecure vehicles can lead to data loss, privacy abuse, physical harm, and revenue loss. This report and Forrester’s emerging technology risk management (ETRM) model helps S&R pros assess and mitigate the reputational, operational, legal, regulatory, and cyber risks of emerging transportation technologies like CVs and AVs.
