    ABSTRACT

    http://dx.doi.org/10.14236/ewic/ICS2018.1

    Over the last decades, cyber-physical systems have evolved from isolated to complex interconnected systems that are remotely accessible. This made them easier to attack, especially since they often contain legacy components with known vulnerabilities. This paper presents a methodology to assess the security of a cyber-physical system. It automatically generates attack trees based on the system architecture. The generated attack trees are processed to provide both technical and non-technical feedback. The assessor can define different attacker models to asses the security of the system with respect to different types of attackers. The methodology is validated by providing tool support and applying it to an example ICS.
