Evidence Graphs model network intrusion evidence and their dependencies, which helps network forensics analysts collate and visualize dependencies. In particular, probabilistic evidence graph provide a way to link probabilities associated with different attack paths with available evidence. Existing work in evidence graphs assume that all evidence is available as one graph. We show how to merge different evidence graphs with or without the help of attack graphs. We show this by providing algorithms and a case study based on attacks on a fileserver and a database server in a lab network environment. An integrated evidence graph that show all attacks launched toward a global network are more useful for forensics analysts and network administrators in searching for forensic evidence and safeguarding networks respectively.
