| Abstract | Model Based Security Engineering (MBSE) is a growing field of research, which is gaining popularity in the domain of Safety, Security, and Resilience Co-Engineering. The System Theoretic Process Analysis (STPA) is a method for systematically analyzing the behavior of complex systems to investigate their failure modes and the Unsafe Control Actions (UCA) that can lead to those failure modes. This paper expands the methodological scope of STPA, by including an iterative Root-Cause Analysis element, which examines the possible emergence of UCAs due to either malfunction, or malicious action. Output of the method are the attributes and constraints of Resilience Modes of system configuration and operation, named "Cyber Safe Position"(CSP). The proposed method is applied in the case study of a Photovoltaic Plant connected to a Virtual Power Plant (VPP). |
