Measuring cyber security in intelligent urban infrastructure systems

An important consideration in secure system design is the ability to verify and validate the level of security of alternative systems architectures. In the case of smart infrastructure, verification and validation processes require suitable metrics that both represent the security of the cyber network as well as the physical processes it supports. Current literature in security metrics offers a plethora of choices which are considered accurate, valid, consistent, current, replicable, comparable and. In this paper, we describe categories of security metrics that can be customized for different intelligent urban infrastructure systems such as intelligent transportation systems (ITS), smartgrids and cognitive radios among others. It includes a smart grid case study.
