Question

You have a customer who is interested in having you install a wireless network in his home, but he is concerned about his neighbors wirelessly using his network to access the Internet. He asks you for a list of security measures he can apply to his wireless network to prevent it from being used by his neighbors. What methods do you mention? (Choose three.)

A. WEP

B. WPA

C. Disable SSID broadcasts

D. MAC filtering

Answer 1

B, C, and D. The SSID, or Service Set Identifier, is the name of the wireless network, and the SSID name is broadcast by default from wireless access points and routers, letting anyone with wireless capacity within range see your network. Disabling SSID broadcasts makes your network “invisible” to your neighbors, so a security breach will be much less likely. WPA, or Wi-Fi Protected Access, was designed to replace WEP by using TKIP, the Temporal Key Integrity Protocol. MAC address filtering allows you to define a list of MAC addresses, which are the physical addresses of network cards, which you either accept or reject on the network. If you enter a list of the MAC addresses for the computers in your household on the wireless router or broadband modem, only computers with those physical addresses will be able to connect. All others will be rejected.
