4.3.3 Wireless MAC Authentication
MAC Address
A MAC (Media Access Control) address is a unique hexadecimal code that identifies a
device on a network. Each network device has such a MAC address.
MAC Authentication
When using MAC authentication, you allow or deny devices to access to your
network based on their MAC address.
Warning: MAC authentication alone is not enough!
Wireless MAC Authentication only offers a limited level of security. Hackers can
easily detect a trusted MAC addresses and clone this trusted MAC address to their
own computer, which will enables them to pass the MAC authentication filter. That’s
why it is important that you first secure your wireless connection (preferably with a
WPA encryption key). This way hackers won’t be able to interpret your wireless
traffic.
