Security Taxonomy for IoT - Cope with complexity and supply-chain


A Taxonomy is presented that aims to assist in coping with the complexity of IoT. It helps considering overarching aspects as well as interdependencies between the single work areas introduced by the Taxonomy. Each single work area is defined below. They are target group-specific; the areas will be filled with concrete security specification later. With this approach, the division of labor is supported, and activities of individual parties can be combined and orchestrated in a way that the IoT system can become an integrated secure whole. Admitting the constant failures to actually secure IoT, it is time for measures of confinement and compensation which in turn requires having an architectural approach making dependencies visible and showing ways of segregation. Moreover, Zero Outage puts other ideas up for discussion such as Zones, Classes, and an extended IT stack.
