In a business-process-support enterprise network, cyber defense and cyber resilience usually become ineffective and even fail in defeating cyberattacks. One of the primary causes is the ineffectiveness of business process impact assessment in the enterprise network. In this paper, we propose a new business process impact assessment method, which measures the impact of an attack towards a business-process- support enterprise network and produces a numerical score for this impact. The key idea is that all attacks derive from exploiting vulnerabilities in the enterprise network, and the impact score is the function result of the severity of the vulnerabilities and the relations between vulnerabilities and business processes. This paper conducts a case study systematically and the result shows the effectiveness of our method.
