Comptia Network+ Wireless Security: MAC Address Filtering
What is MAC Address Filtering?
MAC Address Filtering is a security measure used in wireless networks where only specific MAC addresses are allowed to connect to the network.
Why is it important?
It is considerably helpful in restricting unauthorized access and mitigating potential risks and threats posed by unknown devices. This adds an extra layer of security to your network.
How It Works:
Every device has a unique MAC Address. When a device tries to connect to the network, the router checks its MAC address. If the address is included in the allowed list, the connection is accepted, otherwise it is declined.
Exam Tips: Answering Questions on MAC Address Filtering
1. Understand the basic concept - MAC address filtering allows or disallows devices based on their MAC address.
2. Be aware of the limitations - It's not a foolproof security measure because MAC addresses can be spoofed.
3. Know how to configure MAC address filtering on various devices.
4. Consider the implications - It can be time-consuming to manage if there are many devices.
5. Understand 'MAC Address Filtering' in combination with other security techniques, like WEP/WPA/WPA2.

MAC Address Filtering practice test
MAC address filtering is a security feature that allows network administrators to restrict access to a wireless network by allowing or blocking specific devices based on their hardware (MAC) addresses. While MAC address filtering can provide a basic level of security, it can be easily bypassed. Attackers can avert the filter by 'spoofing' an authorized MAC address, essentially impersonating an approved device to gain network access. Using a combination of security methods including strong encryption (WPA2, WPA3) and regular checks on authorized devices greatly enhances the security of any wireless network.
