Victor wants to use Wireless Zero Configuration (WZC) to establish a wireless network connection using his computer running on Windows XP operating system. Which of the following are the most likely…

The correct answer is B. Attacker by creating a fake wireless network with high power antenna cause Victor's computer C. Information of probing for networks can be viewed using a wireless analyzer and may be used. Wireless Zero Configuration (WZC) on Windows XP exposes users to rogue access point attacks and passive reconnaissance of probe requests by wireless analyzers.

Question

Victor wants to use Wireless Zero Configuration (WZC) to establish a wireless network connection using his computer running on Windows XP operating system. Which of the following are the most likely threats to his computer? Each correct answer represents a complete solution. Choose two.

Why each option

Wireless Zero Configuration (WZC) on Windows XP exposes users to rogue access point attacks and passive reconnaissance of probe requests by wireless analyzers.

AAttacker can use the Ping Flood DoS attack if WZC is used.

Ping Flood DoS attacks are a general network-layer attack unrelated to the WZC service specifically - they can be launched against any networked host regardless of how the wireless connection is managed.

BAttacker by creating a fake wireless network with high power antenna cause Victor's computerCorrect

WZC automatically connects to the wireless network with the strongest signal without verifying the network's authenticity, so an attacker can deploy a rogue access point with a high-power antenna broadcasting a known SSID to lure Victor's computer into connecting to it. This evil twin scenario allows the attacker to intercept all wireless traffic transparently. WZC's automatic connection behavior makes this attack particularly straightforward to execute.

CInformation of probing for networks can be viewed using a wireless analyzer and may be usedCorrect

WZC continuously broadcasts probe request frames to discover previously connected networks, and these frames contain the SSIDs of known networks in plaintext. A wireless packet analyzer can passively capture these probes, revealing the names of networks Victor has previously joined, which can then be used to craft targeted rogue access point attacks.

DIt will not allow the configuration of encryption and MAC filtering. Sending information is not

WZC does support configuration of WEP encryption and can interoperate with MAC filtering at the access point level, so the claim that it does not allow encryption configuration is factually incorrect.
