In this paper, we describe a layered graphical model to analyze the impact of cyber attacks on business processes and services. Our model has three layers: the upper layer models the business processes and their dependencies. The middle layer constructs attack scenarios using evidences in a log files. The lower layer reconstructs the missing attack steps using system calls. Based on the graph produced from the three layers our model computes a quantitative impact on the business processes using the NIST vulnerability scoring system. A case study shows the usability of our model and how it can be applied for both forensic analysis and for mitigating the impact of cyber attacks on the enterprise infrastructure.
