Cyber security architectures for ICS/supervisory control and data acquisition environments

Abstract

Industrial control systems (ICS) are a core component found in many aspects of modern life, from critical national infrastructure to manufacturing and building management. The growth of the Internet has seen these previously isolated systems increasingly integrated with the connected world. Exposure to the Internet and corporate networks inherits all of the security concerns that are relatively well understood in IT environments, further compounded by the different requirements, architectures and component age found in ICS. Many existing IT security technologies and techniques can be applied within an ICS environment, however most require significant reconfiguration or alternate deployment techniques. Some cases require entirely new technology.
