Re: Don't think padlocks are very secure in general
Building a securely locked vault starts with a securely built vault.
I remember the story of a physical intrusion testing team going into a company, with the target being their secure records room. They made it to the door of the room - steel door, keypad access. Very nice. Mounted in a plasterboard wall...
The team member simply punched a hole in the wall, opened the door by turning the inside handle, and put generic safety-awareness stickers over the holes.
