Interesting so Google has an "Internal Afairs" dept who audit themselves ie if some one looks up celbrities details internaly either for curiosity or to sell to the tabloid press.

I know that big telcos have internal security goups and British Telecoms had/has a ferocious rep.

BT got even stricter after some one got a temp job and looked up the x diretory numbers for one of the Queens residences.

After that they started doing posative vetting for team leads on major projects - that is the equivelent of TS clearance in the USA
