MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of Blacklist s and Whitelist s. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network. In theory, MAC filtering allows a network administrator to permit or deny network access to hosts associated with the MAC address, though in practice there are methods to circumvent this form of access control through address modification (" Spoofing ") or the physical exchange of network cards between hosts. Since MAC Filtering was first praised for being the dead bolt on the lock of Wi-Fi Security, it's now really not a good idea to use as a sole means of protecting the network, as cloning the MAC address is possible. In addition, one would want to use WEP or WPA passwords to protect their network, as they make it more difficult to gain access ( WPA being more difficult to defeat than WEP ). |
