How can you restrict access to your wireless network?



You would like to limit access to your network to specific computers. Which wireless security method would provide this type of restriction?

A) Encrypt with WPA or WPA2

B) Disable SSID broadcasts

C) Configure MAC filtering

D) Disable DHCP and assign IP addresses manually


The answer: C) Configure MAC filtering

MAC filtering restricts access to the wireless network by filtering on the hardware address of the wireless devices.


The incorrect answers:

A) Encrypt with WPA or WPA2
Although it’s important to include encryption on your wireless network, WPA or WPA2 doesn’t restrict access to the network based on the computer. As long as you know the WPA or WPA passphrase, you can access the network from any device.

B) Disable SSID broadcasts
SSID broadcasts make your system more visible to the outside world, but they don’t restrict any access to the network.

D) Disable DHCP and assign IP addresses manually
If you can manually set an IP address to connect to the network, then anyone else can too!
