Explain MAC address filtering.

What will be an ideal response?


Most WAPs support MAC address filtering, a method that enables you to limit access to your network based on the physical addresses of wireless NICs. MAC address filtering creates a type of "accepted users" list-an access control list (ACL)-to restrict access to your wireless network. This is a common mitigation technique for undesired access to a network. A table stored in the WAP lists the MAC addresses that are permitted to participate in the wireless network, called a whitelist. Any network frames that don't contain the MAC address of a node listed in the table are rejected.
