Cybersecurity
What is cybersecurity?
Cybersecurity comprises measures to reduce
the risk of unauthorised access by malware or
an Internet attack on vehicle functions, data
and control units.
What are connectivity components?
Control units for data transmission, interfa-
ces, and media and diagnostic connections
are connectivity components, via which in-
formation and data can be exchanged be-
tween the vehicle and external devices or the
Internet. The connectivity components that
are not included in all vehicles are, in particu-
lar:
— Diagnostic port.
— Control unit with built-in eSIM card (OCU).
— Mobile phone interface.
— App-Connect.
— NFC radio technology.
— Bluetooth® interface.
— USB port.
Connectivity components are the key ele-
ments for cyber security. Connectivity com-
ponents are also equipped with security
mechanisms that minimise the risk of unau-
thorised access to vehicle systems.
Security mechanisms
The software and security mechanisms in the
vehicle are subject to ongoing development.
Like with computers or the operating sys-
tems of mobile devices, the software and se-
curity mechanisms in the vehicle may also be
updated at irregular intervals.
Software updates improve the security, sta-
bility and running speeds of the vehicle sys-
tems in vehicles that have already been pro-
duced.
WARNING
In spite of the security mechanisms instal-
led in the vehicle, it is not possible to fully
exclude the risk of unauthorised access by
malware or an internet attack on vehicle
functions and control units. Malware that
has infected the vehicle can influence or
deactivate control units and vehicle func-
tions, or can take over control and lead to
serious accidents and fatal injuries.
·
If the vehicle functions or reacts differ-
ently than normal or behaves in an un-
usual way, reduce your speed (if possi-
ble) immediately and in a controlled
manner and go immediately to the near-
est qualified workshop or seek expert
assistance, e.g. tow recovery.
·
Malware can also access data and infor-
mation that are stored in control units,
in the Infotainment system and on con-
nected data media and paired mobile
devices.
Minimising risks
You too can reduce the risk of unauthorised
access to vehicle systems and functions:
— Use only data media, Bluetooth devices
and mobile devices in the vehicle than do
not contain manipulated data or malware.
— Install system updates provided by Volks-
wagen immediately → page 196.
— Have the vehicle serviced, repaired and
maintained only by a qualified workshop.
Volkswagen recommends using a Volks-
wagen dealership for this purpose.
WARNING
Computers, data media and mobile devices
that are connected to the internet or that
are used in public and private networks
may be infected by manipulated data or
have malware installed on them.
·
Protect computers, data media and mo-
bile devices by means of a suitable anti-
virus program and by generally known
precautionary measures.
