Hflow2 Data Analysis System

Hflow2 is a data coalesing tool for honeynet/network analysis. It allows to coalesce data from snort, p0f, sebekd into a unified cross related data structure stored in a relational database. There is a paper with a more detailed description can be found  here.

The rationale for building hflow2 was the need to create a tool that had several features that were not available in other systems. In particular no tool existed that provided a sebek and network aware offline processing. A comparision of hflow2 with other similar systems follows:

Hflow2Hflow + sebekd sebekd argus netflow

Sebek Aware Yes Yes Yes No No
P0f Aware Yes Yes No No No
Content Based marking Yes No No No No
