Automotive Data Security

Hacking attacks increased greatly in terms of both size and scope over the course of 2014, especially when we consider actions targeting the financial sector.


The gigabytes of information collected, processed, and stored on connected cars make them a potential target for cybercrimes which could have devastating effects on their owners. If connected car data were breached, for example, a large number of accidents could occur. Connected car manufactures should implement data encryption security measures to ensure the safe transfer and storage of the data collected by their vehicles. Furthermore, the software used in connected cars must be of the highest quality in order to ensure that the data it processes is neither collected by unauthorized sources nor used maliciously.


Ensuring data security in connected cars means, essentially, protecting the electronic systems and software that store, transmit, and process data. In other words, those aspects of the car that make it “connected.”


Here are a few key strategies for securing connected car data:


1. Protect Connected Car Hardware

In the case of connected cars, security starts with the design process. Specifically, manufacturers should look to limit ways car data or software can be accessed manually. The easiest way to hack a vehicle is simply to connect a laptop to an IOBD-II port and manipulate its software. Designers should endeavor to curtail the ability of unauthorized users to access car data and software manually by either eliminating exterior access points altogether or enhancing their security.


2. Secure Bluetooth Connections

Bluetooth is a popular and useful integration technique for linking two devices. The strength of Bluetooth’s security protocol lies in the length and randomness of its passkeys, while its weakness resides in its discoverability and connectivity settings. There have been many documented hacks involving cars and Bluetooth connections, including location tracking, denial of service, and the unauthorized access to, and control of, voice channels. Many of these attacks could have been averted by integrating a pre-shared authentication key and other encryption measures with the Bluetooth system.


3. Protect Network Platforms

A secure network platform is required to protect the complex services offered by connected cars. This platform should offer comprehensive security and identity management to and from the vehicle. A secure network platform will provide authentication that identifies a user with a specific security token and ID, as well as with the opportunity to recover passwords.


Modern technology affords many amazing opportunities with regard to connected vehicles. Of course, big opportunities often come with big risks. Protecting vehicles’ ECUs and OBD modules, as well the personal data of drivers, is as complex as it is necessary. Only a fully-integrated approach to connected car security can provide both optimization and protection.
