In face of overwhelming alerts produced by firewalls or intrusion detection devices, it is difficult to assess network threats that we face. In this paper, we propose a threat assessment approach to estimate the impact of attacks on network. The approach employs the Common Vulnerability Scoring System to quantitatively assess network threats and further correlates alerts with contextual information to improve the accuracy of assessment. In the case studies, we demonstrate how the approach is applied in real networks. The experimental results show that the approach can make an accurate assessment of network threats.
