Question

why do vehicle infotainment systems pose security risks?

they do not receive over-the-air updates.
they promote rolljam attacks.
they have no fail-safe measures.
they are connected to the internet.

Explanation:

Analyze the system connectivity

Using the In-Vehicle Infotainment and Automotive Technology knowledge points, we examine how modern vehicle systems operate. Modern infotainment systems are integrated with cellular, Wi-Fi, and Bluetooth capabilities to provide navigation, streaming, and hands-free services.

Evaluate the security implications

This active internet connectivity creates an external attack surface. If a system is connected to the internet, remote attackers can potentially exploit software vulnerabilities to gain unauthorized access to the vehicle's internal networks.

Assess the given options

• "They do not receive over-the-air updates": Incorrect, as many modern systems do receive these updates to patch vulnerabilities.
• "They promote rolljam attacks": Incorrect, as rolljam attacks target wireless keyless entry systems (key fobs), not the infotainment system.
• "They have no fail-safe measures": Incorrect, critical driving systems are typically isolated with safety-critical fail-safes.
• "They are connected to the internet": Correct, internet connectivity is the primary vector that exposes these systems to remote cyber threats.

Answer:

• (A) They do not receive over-the-air updates.
• (B) They promote rolljam attacks.
• (C) They have no fail-safe measures.
• (D) They are connected to the internet. (Correct answer)
