Hey Cesar,

Implementing WEP is a good start. However, you need to be concerned about
the clients themselves as well. I would consider the use of a personal
firewall and VPN client in addition to WEP. You could use the personal
firewall to drop anything destined for the client, and you could force all
network traffic to come to the home office via an IPSec tunnel. The
encryption associated with IPSec is infinitely better than WEP, and will
protect your data better in the long run. Just a thought...

by forcing users to change their WEP key regularly we can meet our
requierements.

Any way to sniff for WEP keys, or to brute force attack a WEP session? If
there is, how hard is it to set up? How much of a risk of a wireless
connection with WEP enabled to be comprimised other than a dedicated, brute
force attack?
