Data security is a very important aspect of any system that allows connectivity with outside users and networks. The spate of reports of hackers being able to remotely deploy airbags or engage emergency braking has led to a certain degree of paranoia among more tech savvy consumers. With new electric steering and automatic parking systems, a hacker may even be able to remotely steer a car. What was once considered a neat feature that had hardly any capacity for malicious use may now be a serious security risk.
BMW Group is increasing the security of data transmission in its vehicles. This is the company’s response to reports from the German Automobile Association (ADAC). The motorist’s association had identified a potential security gap when data is transmitted. The BMW Group has already closed this gap with a new configuration.
The experts from the ADAC had put the company through a strategic review as market leader in vehicle networking. This check revealed a potential security gap affecting the transmission path via the mobile phone network. BMW Group hardware was not impacted. The online capability of BMW Group ConnectedDrive allowed the gap to be closed quickly and safely in all vehicles. Access to functions relevant to driving was excluded at all times. There was no need for vehicles to go to the workshop.
The update is carried out automatically as soon as the vehicle connects up to the BMW Group server or the driver calls up the service configuration manually. The online services of BMW Group ConnectedDrive communicate with this configuration via the HTTPS protocol (HyperText Transfer Protocol Secure) which had previously been used for the service BMW Internet and other functions. The BMW Group ConnectedDrive packages in the vehicle are thereby using encryption which in most cases is also being used by banks for online banking. On the one hand, data are encrypted with the HTTPS protocol, and on the other hand, the identity of the BMW Group server is checked by the vehicle before data are transmitted over the mobile phone network.
In this way, the BMW Group has responded promptly and increased the security of BMW Group ConnectedDrive, because no cases have come to light yet in which data has been called up actively by unauthorised persons from outside or an attempt of this kind is made in the first place.
