GSLC Question #436: Real Exam Question with Answer & Explanation

The correct answer is B. Don't broadcast SSID. Disabling SSID broadcast is the most basic step to reduce wireless network visibility to war drivers scanning for available networks.

Question

You are concerned about war driving bringing hackers attention to your wireless network. What is the most basic step you can take to mitigate this risk?

Options

AImplement WEP
BDon't broadcast SSID
CImplement MAC filtering
DImplement WPA

Explanation

Disabling SSID broadcast is the most basic step to reduce wireless network visibility to war drivers scanning for available networks.

Common mistakes.

A. WEP (Wired Equivalent Privacy) is a deprecated and cryptographically broken encryption protocol that does not adequately protect a wireless network and does not address the visibility issue that war driving exploits.
C. MAC address filtering restricts which devices can connect to the network but does not prevent the network from being discovered by war drivers scanning for SSIDs.
D. WPA (Wi-Fi Protected Access) provides stronger encryption than WEP but still broadcasts the SSID by default, so the network remains visible to war drivers.
