The symbiosis of digital and physical security

The challenge of modern security reminds one of the 1955 Stargazers hit, "Close the door – they're coming through the window": as soon as you've stopped one weak point, the challenges appear somewhere else, and the challenge is getting bigger all the time. From home automation systems to major data centers, the situation seems to be the same - you must assure digital security to guarantee physical security and the other way around. A clear symbiosis.
