Physical Security

Physical security is an oft-overlooked but critical prerequisite for good information security. Software has leaked into every aspect of modern life and now controls access to physical resources as well as to business and personal information. When critically examined, physical security policies and mechanisms have (perhaps have *always*) contained substantial snake oil components, including back doors, extensive use of protection by "security through obscurity", and piece solutions which ignore their environmental context or need to function in a system.
