These include high-profile attacks in a wide range of application domains, from attacks on critical infrastructure, as in the case of the Maroochy Water breach [1], and industrial systems (such as the StuxNet virus attack on an industrial supervisory control and data acquisition system [2], [3] and the German Steel Mill cyberattack [4], [5]), to attacks on modern vehicles [6]-[8]. Even high-assurance military systems were shown to be vulnerable to attacks, as illustrated in the highly publicized downing of the RQ-170 Sentinel U.S. drone [9]-[11]. These incidents have greatly raised awareness of the need for security in cyberphysical systems (CPSs), which feature tight coupling of computation and communication substrates with sensing and actuation components. However, the complexity and heterogeneity of this next generation of safety-critical, networked, and embedded control systems have challenged the existing design methods in which security is usually consider as an afterthought.©2017 IEEECPS SecuritySecurityActuatorsState estimationLinear systemsResilienceReal-time systemscyber-physical systemssafety-critical softwaresecurity of dataattack-resilient cyberphysical systemsattack-resilient state estimatorssecurityhigh-profile attackscritical infrastructureMaroochy Water breachindustrial systemsStuxNet virus attackindustrial supervisory control and data acquisition systemGerman steel mill cyberattackhigh-assurance military systemsattack vulnerabilityRQ-170 Sentinel US droneCPSsafety-critical control systemsnetworked control systemsembedded control systemsComputer EngineeringComputer SciencesArticle
