Application of OOSEM Method in Requirements Analysis of System Security Engineering

OOSEM (Object-Oriented Systems Engineering Method) is a MBSE(Model-Based Systems Engineering) method. OOSEM is scenario-driven and it can analyze the requirements from system-level to component-level. As a selected MBSE method, OOSEM is applied in System security engineering. When focusing on requirement analysis, the OOSEM approach includes system requirements analysis. In OOSEM approach of this paper, SysML model is provided according to requirements analysis of Boundary Security System specially for concerning requirements analysis. In SysML model of Boundary Security System, package diagrams model, use case diagrams model, state machine diagram model and sequence diagram model respectively are applied in OOSEM process. These models provide strong design support for requirement analysis of system security Engineering.
