Abstract:   (1002 Views)
Cyber security situation awareness is important for the analysis of cyberspace, and detection of ever-changing threats. As computer networks and systems continue to increase in complexity and sophistication, the requirements and on a cybersecurity operator increase as well. In this paper, we propose a simulation system to assess the impacts of attacks on cyber assets and identify critical assets. Our proposed system helps to have better situation awareness. For this purpose, we first generate the business process model of the organization. This business process model not only contains information about the mission activities but also contains features of the process itself and the context in which the system operates. Then, we determine the dependency between the processes and the cyber assets of an enterprise. Finally, we simulate some attacks on cyber assets. We evaluate the impacts of attacks on the cyber assets and asset-dependent processes by comparing the Measure of Effectiveness before and after of attack simulation.
