Question 1

A new autonomous vehicle model has reported multiple exploitations in its embedded systems. What embedded security best practice would prevent unauthorized access?

Correct Answer: Implement effective access controls

Implementing effective access controls in the embedded systems can restrict unauthorized access, making exploitation difficult. Other answers do not contribute to preventing unauthorized access or have no relevance to the security of embedded systems.

Question 2

A company's industrial control system relies on numerous embedded devices. Cybersecurity audits reveal that most devices use their default passwords. What risk does this present?

Correct Answer: Unauthorized access and exploitation

Default passwords are often common and easily guessed, increasing the risk of unauthorized access and exploitation. Other answers are unrelated to the issue of default passwords and do not directly affect cybersecurity.

Question 3

An IoT manufacturer is concerned about a potential supply chain attack. Which security measure should be enforced to prevent unauthorized firmware installation during manufacturing?

Correct Answer: Secure boot with cryptographic signature verification

Secure boot with cryptographic signature verification ensures that only authorized firmware with verified signatures can be installed, preventing supply chain attacks. Other measures focus on diverse security aspects but don't address firmware authenticity during manufacturing.
