Answer:
3. Media Access Control (MAC) Filtering
Explanation:
MAC filtering allows or blocks a device from connecting to a network, based on its hardware address.
MAC address filtering adds an extra layer of security by checking the device’s MAC address against a list of agreed addresses.
If the client's address matches one on the router's list, access is granted; otherwise, it does not join the network.
To filter out devices on your network using Macs, you need to create a list of allowed MAC addresses. Only devices whose MAC addresses are on this list will be given services by the DHCP. Also, a list of devices you have tried to connect to your account and been denied. The MAC addresses which are on the Denied list will not be given out by DHCP.
