Media Access Control (MAC) Filtering
As part of the 802.11b standard, every WiFi radio has its unique Media Access Control (MAC) number allocated by the manufacturer. To increase wireless network security, it is possible for an IT manager to program a corporate WiFi access point to accept only certain MAC addresses and filter out all others. The MAC control table thus created works like "call blocking" on a telephone: if a computer with an unknown MAC address tries to connect, the access point will not allow it. However, programming all the authorized users' MAC addresses into all the company's access points can be an arduous task for a large organization and can be time consuming - but for the home technology enthusiast it can be quite effective.
MAC Address
It is also possible for a dedicated hacker to "spoof" a MAC address, by intercepting valid MAC addresses and then programming his or her computer to broadcast using one of those. Despite that, for small network installations, using a MAC filtering technique can a be very effective.
