SECURITY ANALYSIS OF CPS: UNDERSTANDING CURRENT CONCERNS AS A FOUNDATION FOR FUTURE DESIGNABSTRACTCyber-Physical Systems (CPS) or Embedded Systems are now so wide spread that we seeapplications in almost every aspect of our everyday activities. Application fields includeindustrial process control, health care, transportation, financial transaction systems, buildingsecurity systems, home electronics, and automobiles, among others. The “Physical” aspect ofCPS indicates that these systems interact mainly with the physical world and thus cansignificantly impact human and environmental safety as well as large physical infrastructuresystems. CPS failure can therefore have catastrophic consequences. It is thus very important thatCPS operate in a safe, reliable and secure manner. While these systems have seen a lot oftechnological improvements resulting in increased functionality, the issue of security has been alow priority in their design, thus exposing them to several security threats. If we are to benefitfully from the many applications of CPS then security ought to take a central role in their design.The challenges of security design for CPS are aggravated by the lack of standardization inhardware, operating systems, networking and the diverse physical environment. Addressing suchchallenges needs a strong collaboration between those skilled in CPS component design as wellas those skilled in security and other aspects of these complex systems.This study includes an analysis of the available literature and design practices in several CPSapplication fields, with an emphasis on design for security. The Information Technologycommunity has a rich background in security analysis, although not previously applied to CPSdesign. Thus a security analysis methodology for CPS was developed from recognized securityanalysis for conventional computing. Assets, security threats and risks are analyzed relative to aCPS environment. Current security solutions are presented and compared. We discussevolutionary changes of CPS leading to their growing importance within computing disciplinesand their increasing role in large, heterogeneous distributed systems. Finally the integrativenature of CPS design is discussed and the role of Information Technology as a major contributorto CPS design for security is emphasized.
