Wep is secure as long as you don't see sharing all your resources with
an attacker.

No, WEP can be cracked in less than ten minutes (even on a network
without much traffic - a hacker can stimulate his own traffic). Rotating
keys just isn't enough to cover the weaknesses, unless you want to
rotate keys every three minutes. :) Personally I think WPA is the only
way to go, or else you might as well keep the network open and turn WEP
off entirely.

Hi
I am responsible for a large wireless infrastructure upgrade. Right
now my plan is use PEAP w MSCHAP v2 with dynamic WEP crypto for my
corporate SSID (I have others with much lower security requirements).
I cannot easily go to WPA without ditching all my current devices that
do not support it (good luck getting that past the CFO). We have a
lot of physical security and surveillance with very tight controls, my
primary area of concern would be people like myself sitting in the
parking lot. Due to one of our applications, we will be sending a
clear strong signal to the parking lot. Is this enough security and
encryption to significantly slow intrusion attempts? Between
direction finding capabilities of the Access Points and our roaming
guards it would be a matter of time before we detected them.
Thanks
