A revolution is underway in the automotive industry. The car is no longer simply a means of getting from here to there. Todays car reaches out for music streamed from the cloud, allows hands-free phone calls, and provides real-time traffic information and personalised roadside assistance. <\/p>\n
Almost every modern automobile feature speed monitoring, fuel efficiency tracking, anti-lock braking, traction and skid-control is now digitised to provide drivers with easier, safer operation and better information. <\/p>\n

Recent innovations enable automobiles to monitor and adjust their position on the highway, alerting drivers if they are drifting out of their lane, even automatically slowing down when they get too close to another car. And whether were ready or not, well soon be sharing the roads with autonomous vehicles. <\/p>\n
Driving the technology revolution in the automotive industry is software, and that software is built on a core of open source. Open source use is pervasive across every industry vertical, including the automotive industry. <\/p>\n
When it comes to software, every auto manufacturer wants to spend less time on what are becoming commoditiessuch as the core operating system and components connecting the various pieces togetherand focus on features that will differentiate their brand. The open source model supports that objective by expediting every aspect of agile product development. <\/p>\n
But just as lean manufacturing and ISO-9000 practices brought greater agility and quality to the automotive industry, visibility and control over open source will be essential to maintaining the security, license compliance, and code quality of automotive software applications and platforms. <\/p>\n
When someonethinks of building software, we think of it being created by an internal development teams. But auto manufacturers rely on hundreds of independent vendors supplying hardware and software components to Tier 1 and 2 vendors as well as directly to OEMs. <\/p>\n

The software from each of those vendors is likely a mix of custom code written by the vendor and third-party code (both proprietary and open source). With tens of millions of lines of code executing on as many as 100 microprocessor-based electronic control units (ECUs) networked throughout the car, understanding exactly which open source components are part of the mix can be extremely difficult for the OEMs. When you add in the fact that over 3,000 open source vulnerabilities are reported every year, the security implications are clear. <\/p>\n
Lets assume a Tier 2 vendor is using an open source component, and a vulnerability is disclosed. <\/p>\n
First the vendor needs to know they are using that specific open source component. Next they need to be monitoring sources in order to know about the newly reported vulnerability. Then they need to re-factor and test their code to remediate the issue. <\/p>\n
When all this is done, the software update needs to go to the OEM or Tier 1 vendor, be incorporated into an update of that entitys component and, ultimately, be updated in each consumers vehicle. <\/p>\n
Updating presents its own challenges. When security researchers demonstrated in 2015 that they could hack a Jeep over the Internet to hijack its brakes and transmission, it posed a security risk serious enough that Chrysler recalled 1.4 million vehicles to fix the bug that enabled the attack. Recall is in quotes because Chrysler didnt actually require owners to bring their vehicles to a dealer. Instead, they were sent a USB drive with a software update they could self-install. But how many owners are comfortable updating the software in their cars? <\/p>\n

Vehicles can be updated during routine service, of course, but probably only if the service is provided by an authorised dealer, a prospect that decreases as a vehicle ages. Over-the-air updates of software are still the exception rather than the rule, and may require that the vehicle be stopped for safety reasons. After all, we probably dont want a software reboot when a vehicle is moving at highway speed. <\/p>\n
Your cell phone may have a practical life of 2-3 years, but receives regular operating systems updates and perhaps hundreds of app updates each year. The laptop Im using to write this likewise receives regular updates and patches, and will likely be replaced after 3-5 years. This is the typical lifecycle software vendors are used to addressing. <\/p>\n
A modern car, however, is in design for years prior to production, and the average vehicle may be on the road for 10-15 years. Supporting software over that period of time requires a different thought process. Vendors (and open source communities) need to be considered in light of the operational risk they present. Questions vendors need to ask include: <\/p>\n
How sure are you that the components you are using will be supported by the open source community in the future? Are you prepared to provide ongoing support for projects if the community (or vendor) abandons them? What does the release cycle look like? How many vulnerabilities has the component had over the last few years compared to the size of the code base? Is the community security-aware? <\/p>\n

When a supplier or auto OEM is not aware all the open source in use in its products software, it cant defend against attacks targeting vulnerabilities in those open source components. Any organisation leveraging connected car technology will need to examine the software eco-system its using to deliver those features, and account for open source identification and management in its security program. <\/p>\n
Both auto OEMS and their suppliers should adopt management practices that inventories open source software; that maps software against known vulnerabilities as well as alerting to new security threats; that identifies potential licensing and code quality risks; and that can maximise the benefits of open source while effectively managing risks. <\/p>\n<\/p>\n
