[MLB-WIRELESS] WEP vs MAC Filter vs WEP + MAC Filter

A wardriver will usually continue on driving if you have WEP turned on,
there are plenty of open nodes out there they can use.
To have any kind of real world security I recommend a combination of WEP
and Mac filtering.
I believe if you just have Mac address filtering, someone could sniff
the packets, read the source or destination mac address of the packet,
set their cards mac address to that and have access to your network
With WEP, I believe you need to listen to at least 5,000,000 to
10,000,000 packets (which is a few hours of good solid traffic) in order
to break it
using software like Airsnort.
To stop a random wardriver: WEP encryption (can even be 64bit), its
easier for them to drive another 200m and find an open node.
To stop a linux script kiddie: WEP plus Mac addy filtering
To stop most things: WPA on a 1-2 minute key rotation, with mac address
filtering. (I read on slashdot it takes the FBI at least 3 mins to break
WEP which is pretty amazing, but if your key changes every 2 mins or so,
im not sure even they can get in).
