Computer security aspects in industrial instrumentation and measurements

Industrial Control Systems (ICS), formerly isolated proprietary systems, are giving place to highly-connected systems, implemented using widespread operating systems and network protocols on public networks. Such standardization trend opens the door to security threats previously restricted to the corporate and personal computing areas. This paper presents how the main concepts of security in conventional computing systems can be exploited in dependability aspects of ICS, and presents some considerations on how security aspects of a standard-based could be applied to a typical control board used in industrial applications involving measurement.
