In computer networking, MAC Filtering refers to a security access control methodology whereby the 48-bit
address(XX:XX:XX:XX:XX:XX) assigned to each network device is used to determine access to the network.
MAC addresses are uniquely assigned to each network device, so using MAC filtering on a network permits and denies
network access to specific devices through the use of black lists and white lists. 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 white list entry for each device that he would use to access
the network.
While giving a wireless network some additional protection, MAC Filtering can be circumvented by scanning a valid
MAC and then changing the own MAC into a validated one.
