Certified Information Systems Auditor (CISA) — Question 619

Which of the following is the MOST effective way to maintain network integrity when using mobile devices?

Answer options

• A. Implement outbound firewall rules.
• B. Implement network access control.
• C. Perform network reviews.
• D. Review access control lists.

Correct answer: B

Explanation

Implementing network access control (NAC) is crucial as it ensures that only authorized devices can access the network, thus maintaining integrity. Outbound firewall rules, network reviews, and access control lists are important but do not specifically address the unique challenges posed by mobile devices as effectively as NAC does.
