4.5 Connected Vehicle Challenges

There are a number of challenges associated with the connected vehicle. These
challenges are described in the following section.

Security
The subject of security related to connected vehicles was recently brought to
the fore by an article published in Wired magazine, describing how researchers
pretending to be hackers were able to gain remote control of the vehicle sys-
tems within a popular brand of vehicles [6]. The publicity associated with the
incident caused the manufacturer in question to issue a recall for 1.4 million ve-
hicles. We live in an age of ubiquitous access to information. We have the ability
to remain connected to the web through wireline and wireless technologies 24
hours per day. The use of telecommunication technologies and the Internet is
shared across the globe, enabling it to be a cost-effective communication means.
This sharing also means that it is open to abuse. There have been numer-
ous high-profile incidents over the past few years in which sensitive data has
