Question

An attacker used an illegal access point (AP) with a very strong signal near a wireless network. If the attacker performed a jamming attack, which of the following would mitigate this type of network disruption?

A) Increasing the signal strength of the legitimate wireless network.

B) Changing the Wi-Fi network's encryption method.

C) Implementing wireless intrusion detection systems.

D) Disabling the wireless network temporarily.

E) Changing the SSID (Service Set Identifier) of the wireless network regularly.

Answer 1

To mitigate a jamming attack on a wireless network, implementing wireless intrusion detection systems is the most effective strategy. Other measures like A. increasing signal strength or changing encryption methods do not address the issue.

Step-by-step explanation:

If an attacker performs a jamming attack on a wireless network using an illegal access point (AP) with a strong signal, the most effective way to mitigate this network disruption would be to implement wireless intrusion detection systems (WIDS). A WIDS can detect the presence of unauthorized APs and jamming attacks, and it can help in automatically taking measures to neutralize the threat.

Increasing the signal strength of the legitimate network may not be effective if the jamming signal is overpowering. Changing the encryption method or the SSID of the network will not prevent a jamming attack since this type of attack does not rely on decrypting the wireless traffic but rather disrupting the signal itself. Disabling the wireless network is a temporary fix that would cease all legitimate activity, which is not a sustainable solution.
