Modeling Cyber Threats with SysML

Abstract

Abstract Advanced Persistent Cyber Threats (APCT) jeopardize all seven layers in the Open System Interconnect (OSI). Scalable Modeled Based Engineering (MBE) methodologies can address APCT by leveraging industry standard SysML techniques by automating threat assessment for a multitude of operational scenarios. This paper provides a use case demonstrating how SysML can be combined with simulation to improve cyber defenses.
