Using Bayesian Networks to Fuse Intrusion Evidences and Detect Zero-Day Attack Paths,nce-graph-based Bayesian network is able to incorporate the collected intrusion evidence and infer the probabilities of object instances being infected. By connecting the instances with high probabilities, ZePro is able to generate the zero-day attack paths. This chapter evaluated the effectiveness of ZePro for zero-day attack path identification.

Measuring the Overall Network Security by Combining CVSS Scores Based on Attack Graphs and Bayesianed. This chapter examines several approaches to combining the CVSS scores of individual vulnerabilities into an overall measure for network security. First, we convert CVSS base scores into probabilities and then propagate such probabilities along attack paths in an attack graph in order to obtain a

Refining CVSS-Based Network Security Metrics by Examining the Base Scores,rabilities provides a measurement of the overall security of networks with respect to potential attacks. However, most existing approaches to combining such scores, either based on attack graphs or Bayesian networks, share two limitations. First, a dependency relationship between vulnerabilities wil

Security Risk Analysis of Enterprise Networks Using Probabilistic Attack Graphs,ll security of an enterprise network cannot be determined by simply counting the number of vulnerabilities. To more accurately assess the security of enterprise systems, one must understand how vulnerabilities can be combined and exploited to stage an attack. Composition of vulnerabilities can be mo
