An IS auditor finds that conference rooms have active network ports. Which of the following is MOST important to ensure?
Correct Answer: B
If the conference rooms have access to the corporate network, unauthorized users may be able to connect to the corporate network; therefore, both networks should be isolated either via a firewall or being physically separated.
