An employee at a client company called today and asked if it was possible to copy the company's data onto his home machine. When I told him that I couldn't help him, he asked if I had the phone number of an old colleague who has left the IT business. He's going to find someone.
The network is well secured against everything else, but I didn't think I'd have to protect it from within.
I only have a couple of days to stop him from walking out with the goods. (Having him fired is not an option at this point). I thought about EFS, but understand that you can just copy the files to a FAT drive and they're decrypted.
