Explanation
WPA encryption and MAC address filtering are the two controls that directly restrict which devices can authenticate and connect to a wireless network.
Common mistakes.
- B. Changing wireless channels affects interference and performance but does not restrict which users can connect to the network.
- D. Changing wireless speed standards (e.g., switching from 802.11n to 802.11g) alters performance characteristics but places no access restriction on unauthorized users.
- E. Disabling (hiding) the SSID provides only security through obscurity - the network is still visible to a wireless scanner and does not prevent an unauthorized user from connecting if they know the network name.
