Abstract
Industrial Controlled Systems (ICSs) are prone to cyber-attacks exploiting weaknesses in their units. This chapter illustrates through an example of a pressurized water Nuclear Power Plant (NPP) control system how these vulnerabilities may be exploited by an attacker compromising the system. The control system is described by Architecture Analysis and Design Language (AADL), and then checked with a security property via JKind checker. The resulted Lustre file is later fed to an Attack Scenarios Generation and Filtration Tool (ASGFT). This tool automatically generates all possible attack scenarios resulting in overall plant disruption. The union of these attack scenarios is visualized by a Visualizer.exe, a Graphical User Interface (GUI) built employing C#.
