There are two worlds of computer security - high-end systems and then everything else. Both high- and low-end systems typically employ “top-down” defenses to harden their attack surfaces. These are “software-only” security techniques.
At the Automated Vehicles Symposium (AVS) 2017, I addressed a plenary talk to the ~1,500 attendees, stating that even though it is unanimously considered as paramount, cybersecurity is still an after-thought. Or at least it still feels like it. Indeed, for the last two AVS editions, the cybersecurity breakout session reported similar open challenges, but no real changes have been seen since. In order to move the security needle, we took a different approach and didn't organize a cybersecurity breakout session. Instead, we identified that the missing components were the lack of inputs coming from the community of experts. To be able to build a more resilient system, cybersecurity experts should know about the limitations of each subsystem, and possible "nightmare scenarios".

Car makers use cryptographic keys for a variety of purposes, including Over-The-Air (OTA) software updates, security immobilizers, inter-module communications, and Vehicle-to-Everything (V2X) communication security. Key Management Systems (KMS) are very complex, as the manufacturer has to manage dozens of keys for each car model, both at production and when new components are introduced during repairs, and they must maintain these keys over the long lifetime of a car. Key Management is a daunting task.
On Friday October 21, 2016, Dyn was subjected to two large Distributed Denial of Service (DDoS) attacks against their internet-address lookup Managed DNS infrastructure. The attackers used Mirai botnets launched from over 100,000 endpoints including cameras, DVRs and baby monitors to generate the significant volume of attack traffic. Affected services included Amazon, Spotify, Netflix and the New York Times.
Toyota recently sent a letter to the Federal Communications Commission (FCC) urging them to protect the 5.9 GHz band for Dedicated Short Range Communications (DSRC), the technology behind Vehicle-to-Vehicle (V2V)communications. Toyota noted that “The market leaders in Japan (Toyota), Europe (Volkswagen), and the United States (General Motors) have now either begun deployment of DSRC technology or announced a specific deployment plan for the technology.”
Tesla is the only major automaker that offers over the air (OTA) updates of both software and firmware. This allows Tesla to add new features like new voice commands, driver profiles or blind spot warnings that weren’t available when the car was purchased. It also allows them to fix bugs that were either causing the car to not function as intended or to discourage potential hackers by patching vulnerabilities soon after they are discovered.
Recently, the UK government released "The key principles of vehicle cyber security for connected and automated vehicles." This guidance document provides key cyber security principles for use by the automotive industry and its suppliers. This follows the US Government's guidelines that were issued last fall.
