CompTIA Security+ Question I-45

Which of the following best practices makes a wireless network more difficult to find?

A. Implement MAC filtering
C. Disable SSID broadcast
D. Power down unused WAPs

Answer: C

Network administrators may choose to disable SSID broadcast to hide their network from unauthorized personnel. However, the SSID is still needed to direct packets to and from the base station, so it’s a discoverable value using a wireless packet sniffer. Thus, the SSID should be disabled if the network isn’t for public use.
