anyone got recommendations for books that go into technical detail about the physical security design elements and defeat processes relating to modern strongrooms (bank vaults) and other high security safes?

I recently read Safecracker by Dave McOmie, which covered the general features at a high level, but I'd like something a bit more detailed and technically focused. I have High Security Mechanical Locks by Pulford too, but that's focused on locks specifically rather than strongroom phys-sec.
