Wireless PC Lock - part 2
Over the last several days, I've been getting more and more requests for my updated Wireless PC Lock software that I described way back last year.
Possibly, it's because of stories like this one:
At New York-based Big Four accounting firm Ernst & Young, the security department confiscates laptops if they are unlocked when not in use, say employees (who wish to remain anonymous). To reclaim the confiscated PCs, workers must explain why they forgot to lock their machines and then they get a quick refresher course in security. These employees say they dread that walk to IT, so many have gotten better at remembering to lock them.
Well, that's a really amusing story, and I will confess that at my workplace, any workstation found unlocked tends to be used to invite the rest of the team out for lunch - you don't forget to lock your workstation too often [whether that's because lunch for a whole team is expensive, or because you just don't want to have to spend an hour with your colleagues, is beyond me].
I work in a physically-secured building, where RFID cards have to be used to get in and out, but the problem of locked workstations is still an important one to us - the data that I can access is quite different from the data that can be accessed by the people across the hall, or by the people in other buildings. And if any inappropriate data access occurs from my workstation under my account, it'll be my job that's on the line - nobody's going to try dusting for fingerprints to check that it wasn't me.
So, I like to have an 'insurance policy' against forgetting that simple Windows-L keystroke. My insurance policy is the Wireless PC Lock, which detects when I get up and walk out of range, locking my computer if I haven't already done so.
The crap software that comes with the Wireless PC Lock is a problem, though. It requires to be installed, which I don't want (because I'm a restricted user); it doesn't really lock the workstation (it puts up a full-screen bitmap of dolphins); it unlocks the workstation when you get back in range (even when it's on the other side of a wall); etc, etc.
So, I decided it would be handy to have some replacement software that could be installed / used on a per-user basis. For the first release, this is strictly personal software - there's no install. You copy the EXE into place, and run it from startup.
Insert the USB stick into your system and away we go. Right-click the new icon in your system tray (it looks a little like the transmitter fob on my unit - yours may be different), and choose to register with your fob.
The program will ask you to turn the fob off and then on again, so that it knows whose fob to lock against; once you have this set, that may be all the configuration you need to do - but of course, I have added configuration for the timeouts.
And, if you go and visit your Windows sound schemes, you'll find there are additional sounds for the Wireless PC Lock, allowing you to hear when you're about to get locked out by an absence of wireless fob.
Obviously, this is a real lock of your workstation that's going to happen, so you will, yes, have to type in your password every time you come back to your workstation - your fob carries a two-byte code, which is not nearly difficult enough to hack to make it a valid logon protector. Sorry.
If you lose your fob, or your fob loses batteries, don't worry - you can use your password to unlock, as usual, and then once you're unlocked, the Wireless PC Lock software won't activate again until it registers the presence of your fob again. Just remember that the Wireless PC Lock is a convenience measure, and is a "backup" against you forgetting to press Windows-L to lock up your machine when you're walking away from it.
I've attached a zip file containing the Wireless PC Lock application - please let me know what you think of it!
