I remember assessing the vulnerability of a data centre for a large multinational client based in a faraway not to be named land. The cooling systems for the computers had been removed from the roof - and placed only a short grenade throw from the fence and adjacent roadway - to accommodate a panoramic vista for executives at their end of the week barbeques.
My vulnerability assessment report - like the child's ubiquitous homework - was "eaten by the dog"; my camera's memory card confiscated; and evidence of my consulting work was erased even to the extent of non payment.
"No photos / No paperwork" in another of its various forms.
