As with any system that provides external connectivity, a significant consideration in deploying a telematics/infotainment system is the potential security risk the system could have on the vehicle platform.

Telematics/infotainment systems share a few common characteristics: The IEEE Center for Secure Design (CSD) developed this document as a direct result of a discussion from experts on recurring security flaws and vulnerabilities identified within vehicle telematics/infotainment systems.

The following tables detail the services and protocols affected by the security levels, listed in Table 3-2, if you choose to apply one at cold-install- or update-time: blocks all incoming WBEM connections via IPFilter, though local and outbound communication is not blocked.
