What is a limitation of applying Media Access Control (MAC) filtering on network devices?

Applying Media Access Control (MAC) filtering comes with the significant limitation that new authorized devices require updates to the safe list. MAC filtering is a security measure used on wireless networks to allow only devices with specific MAC addresses to connect. Therefore, whenever a new device is added to the network, the administrator must manually add its MAC address to the list of approved devices. This process can create delays and administrative overhead, particularly in environments where devices are frequently added or removed, such as offices or homes with many users and devices.

This requirement for constant updating makes MAC filtering less practical for networks that are dynamic and have numerous devices connecting regularly, as it does not automate the authorization process and can lead to service interruptions for legitimate users.
