24 Questions
What is a technique mentioned in the text for finding the source of a jamming signal?
Fox hunt
How might an attacker disrupt communication by jamming in a wireless network?
Sending jamming signals only when someone tries to communicate
Why does an attacker need to be relatively close to a wireless network to disrupt it with jamming signals?
To overwhelm the good signal
What might an attacker be doing if they are intermittently sending random data to disrupt communication?
Interfering with the normal flow of communication
What equipment is required for a successful fox hunt to locate a jamming signal source?
Directional antenna and headphones
Which factor makes finding and resolving jamming issues challenging?
Lack of right equipment and techniques
What is the goal of RF jamming?
To disrupt a wireless network
How does the signal-to-noise ratio affect communication on a wireless network?
A high signal-to-noise ratio improves communication
What unintentional event could disrupt a wireless signal other than an attack?
Turning on a microwave oven
How can attackers disrupt a wireless network using RF jamming?
By sending constant random information to overwhelm the signal
What happens if noise overwhelms the good signal in a wireless network?
The signal-to-noise ratio decreases and communication is disrupted
Why might an attacker send additional noise onto a wireless network?
To prevent someone else from receiving the wireless signal
What is the main goal of a radio frequency jamming attack?
To decrease the signal-to-noise ratio at the receiving device
How does the signal-to-noise ratio impact communication on a wireless network?
It prevents the wireless signal from being received
What is a common method used by attackers to create noise and conflict on a wireless spectrum?
Sending constant, random information over the network
In what scenario might a microwave oven unintentionally disrupt a wireless signal?
By causing interference that affects signal reception
What impact does an attacker intentionally sending additional noise onto a wireless network have?
Prevents others from receiving the wireless signal
How does overwhelming the good signal with noise affect communication in a wireless network?
Decreases the signal-to-noise ratio
How might an attacker put a twist on jamming to limit a specific device's communication on a network?
By sending jamming signals only when the targeted device tries to communicate.
What technique is used to locate the source of a jamming signal in the text?
Conducting a fox hunt with a directional antenna.
Why does an attacker need to be physically close to a wireless network to disrupt it with jamming signals?
To overwhelm the good signal with the jamming signal.
In what scenario might an attacker use intermittent random data to disrupt communication?
To disrupt communication without constant jamming.
What challenge might arise when trying to locate a jamming signal source?
Locating the source accurately without false positives.
How does an attacker disrupt normal communication flow on a wireless network by sending legitimate frames?
By using up available bandwidth to transmit these frames.
Learn about radio frequency jamming, a way for attackers to disrupt wireless networks, leading to denial of service situations. Understand how it works by decreasing the signal-to-noise ratio at receiving devices like end stations or access points.
