| Abstract |
In this talk we introduce ForNet, a distributed network logging mechanism to aid digital forensics over wide area networks. We describe the need for such a system, review related work, present the architecture of the system, and discuss key research issues. We then describe the design and implementation of a prototype system that processes packets in a network and is able to attribute query payloads to source and destination hosts in the local network. It is based on a novel data structure called a Hierarchical Bloom Filter (HBF). An HBF allows us to form compact digests of payloads and provide probabilistic answers to membership queries. Our system is robust against certain packet transformations and flexible enough to be used if the query string is spread across several packets. Performance analysis and experimental results of the prototype system are also presented demonstrating its practicality and efficacy. |
