W

ith the proliferation of advanced
driver assistance systems
(ADAS) among the fleet, the
hardening of the vehicle networks and
modules is front and center for many
vehicle manufacturers. Today, technicians
are already facing challenges when interfacing late-model vehicle systems. This
article will help you prepare for these
security-laden vehicles, which will help
smooth out future service and repair operations for you and your shop.
As we entered the 21st century, the
automobile was becoming more complex
due to the implementation of additional
micro-controllers. Near the end of that
first decade, the automobile was beginning
to experience a technology shift with the
addition of driver assistance features. At
that time, we were beginning to see vehicles
running on approximately 50 million lines
of code. Today, it is not uncommon to see
vehicles running on more than 150 million
lines of code. What's driving all this technology? There are three primary drivers:
1. Safety
2. Emissions/fuel economy
3. Driver convenience
As manufacturers continued to develop
and refine systems to enhance the vehicle, the focus on various facets of vehicle
security wasn't given high priority. Today's
vehicles contain numerous attack vectors
that are rarely discussed. Keyless entry,
TPMS, cellular data, telematics, and the
OBD-II diagnostic connector are all present vulnerabilities.
