Why MAC Filtering Alone May Not Be Enough

This is yet another reason why I don’t have or want WiFi in my apartment. I
just isn’t secure, no matter what you do with it. I worked in data security
in the Pentagon years ago and the only really secure PC is locked in a safe
with no power and no one knows the combination. But wired ethernet is a lot
more secure than wireless.

(and while I’m out, Bluetooth to cellular 1xRTT is fine, thanks)

We hear it all the time — WEPs broke, so why use it? Most people then
move to MAC filtering and are content to just leave it at that. However, as
this TechRepublic article explains, that may not be enough. The short
version: with little effort, an intruder can pull a valid MAC address out
of the air and bind it to their card, thus spoofing a valid address and
getting onto the network.
