Question

how could a criminal access an in-vehicle communication system?

through disconnected components
by overriding system operations
through the on-board diagnostics port
by using a tampering alarm

Explanation:

Analyze the question

The question asks how a criminal could gain access to an in-vehicle communication system.

Evaluate the options

• through disconnected components: Disconnected components do not transmit signals, making them an unlikely entry point.
• by overriding system operations: Overriding operations is typically an objective or result of gaining access, rather than the initial physical or logical entry method itself.
• through the on-board diagnostics port: The On-Board Diagnostics (OBD) port provides direct physical access to the internal In-Vehicle Networks (such as the CAN bus). This port is designed for diagnostics and can be exploited to inject malicious messages.
• by using a tampering alarm: A tampering alarm is a security defense mechanism, not an entry vector for an attacker.

Select the correct option

The OBD port is a well-known physical access point that connects directly to the vehicle's internal communication networks.

Answer:

• (A) through disconnected components
• (B) by overriding system operations
• (C) through the on-board diagnostics port (Correct answer)
• (D) by using a tampering alarm
