What is the difference between classified, confidential, secret, and top secret ?

They're different levels of clearance. People have to be cleared to see secret stuff, but there's stuff even they can't see, and that's top secret. 'Classified' means something has been classified either secret or top secret. Confidential is 'company confidential', i.e. not a govt. thing but companies protecting their own secrets.
I got a secret clearance once, in a job I had. In those days I only had to sign a paper promising I wasn't a crook (had no criminal record). Today I think it's harder.
