When Things Just Work…
I just love it when things just work. For instance, this morning, I added wireless networking capability on the little production sub-LAN at work. I selected a Linksys WAP45G wireless access point. Within about 10 minutes, I had three laptops and a PDA up and on-line.
That’s the way, uh-huh, uh-huh, I like it, uh-huh, uh-huh!

WPA2 encryption, I hope.
For the sake of simplicity, I used 64-bit WEP — I know it, it knows me, and it’s good enough for this location.
I say that, because this section of this building was part of the Bendix test lab for some of their secret RF stuff, and is fairly heavily shielded. Someone would have to be right on top of me to even find the signal. And then, they’ve have to figure out the key.
At that point, all they’d be able to access is a directory with some scripts and some audio and video files, and they’d get access to a lousy-slow, heavily firewalled internet connection.
Oh, yeah. The WAP’s got WPA2 available, should I decide it’s necessary. It only takes a few minutes to switch.
“And then, they’ve have to figure out the key.”
Which is real easy. WEP’s broken so badly, it literally takes seconds to tumble the key if you capture a few minutes worth of packets.
If they’ve got access to file shares via WiFi, they’ve got access to more. They’re no longer in front of the port firewall in the WRT54G, but behind it on your LAN. And that’s a good place to mount an attack on any unpatched OS weaknesses.
Getting signal’s the key, but just FYI…
Well, as I said, if it turns out there’s any kind of threat, it’s easy to change. And, they’ve also got to figure out the passwords to the shares. And, no, the passwords are new ones!
