Defense in depth (computing)

A graphical representation of the onion model of Defense in Depth, a concept in Information Security.

Defense in Depth (also known as layered security and layered defense) is an information assurance (IA) concept.[1] It uses multiple layers of security controls (defenses) placed throughout an information technology (IT) system.[1] The multiple layers are not of the same security tool. It uses several different kinds of security with each protecting against a different security attack.[1]
