Certified Ethical Hacker (CEH v10) — Question 29

Why containers are less secure than virtual machines?

Answer options

• A. Host OS on containers has a larger surface attack.
• B. Containers are attached to the same virtual network.
• C. Containers may fulfill disk space of the host.
• D. A compromise container may cause a CPU starvation of the host.

Correct answer: D

Explanation

The correct answer, D, highlights that if a container is compromised, it can monopolize CPU resources, leading to performance issues for the host. Option A discusses the attack surface but does not directly address the security implications in the same way. Option B is true but does not relate specifically to security concerns, while option C, although relevant to resource management, doesn't pertain to the security of the host.
