The Perfect ICS Storm

As manufacturing Industrial Control System (ICS) architectural designs have evolved from isolated and proprietary systems with physical separation to a layered architecture using more standard IT components to the latest trend of Industrial Internet of Things (IIoT); so too have the challenges associated with securing these environments. Stir in a little concept know as Internet off-loading and the environment becomes ripe for a Perfect ICS Storm. Conflicting concepts of isolation vs convergence and centralized vs distributed lead to a complex array of security concerns. This paper will pull together some of the detection and response challenges which should not be overlooked as the architectural landscape continues to evolve.
