Abstract
The appearance of Stuxnet malware changed the idea of security on critical
infrastructures greatly. However, in previous studies, cyber security issues have
been addressed only from an IT security perspective, with a focus on the
detection of malicious activities and the elimination of IT threats. However,
these studies missed out the discussion relating to the robustness of the designed
plant system. In this research, the relation between information system security
and physical plant safety is defined on the basis of a novel framework. This
study introduces a preliminary approach which tackles plant safety and security
from a more comprehensive point of view. In this context, not only computer
security is considered, but also plant availability and robustness. In particular,
the presented methodology allows us to understand how unsafe activities and
cyber-attacks may propagate throughout the plant system and affect the physical
side of the plant.
Keywords: control systems security, plant safety, cyber-terror.
