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?

1) Use a Wi-Fi analyzer.
2) Disable the offending radio source.
3) Boost the signal of the legitimate equipment.
4) Install a personal area network (PAN).

Answer 1

To counteract a jamming attack by an illegal access point, using a Wi-Fi analyzer to identify and disable the offending source is the most effective approach. Boosting signal strength or installing a PAN could also be considered, although they have limitations.

Step-by-step explanation:

To mitigate a jamming attack performed by an attacker using an illegal access point with a strong signal near a wireless network, the following options can help:

• Use a Wi-Fi analyzer: This tool can help identify unauthorized access points and signal interference. It also can be used to detect a jamming attack by showing unusual signal strengths or gaps in connectivity.
• Disable the offending radio source: If the device causing interference can be located, it should be turned off or disabled to prevent the jammer from disrupting the network.
• Boost the signal of the legitimate equipment: Increasing the power output of authorized devices may help counteract the effects of the jamming signal, although this could lead to regulatory issues or cause interference to other systems.
• Install a personal area network (PAN): This doesn't directly address the jamming issue, as PANs typically rely on technologies such as Bluetooth, which could also be affected by interference.

Therefore, the most effective methods to counteract a jamming attack in this scenario would be to use a Wi-Fi analyzer and disable the offending radio source.
