Question 730
A guest SSID is connected to a network that allows lateral traffic into staff database servers. Which ongoing operational safeguard best reduces the chance of recurrence?
Explanation
Correct Answer
This is a continuing control for the failure mode in which the guest role's effective firewall policy permits unintended east-west and internal traffic. It complements the immediate fix instead of relying on a one-off correction.
Incorrect Answers
That control is useful for a different failure, such as when a network engineer opens full access for contractors to troubleshoot one campus printer. It would leave the present failure mode insufficiently addressed.
That control is useful for a different failure, such as when a branch firewall permits internal IoT devices to initiate sessions to the NAC administration console by a legacy broad access rule. It would leave the present failure mode insufficiently addressed.
That control is useful for a different failure, such as when an IoT camera VLAN receives full access to network management interfaces because the firewall default rule is permissive. It would leave the present failure mode insufficiently addressed.
