I read a research article about packet trace anonymization co-authored by a
researcher from ICIR using Bro in its approach.
The paper:
A High-level Programming Environment for Packet Trace Anonymization and
Ruoming Pang, Department of Computer Science, Princeton University
Vern Paxson, International Computer Science Institute

To quote the authors, "We implemented the anonymizer as an extension to Bro
[16], a network intrusion detection system, to take advantage of its
parsers and its built-in language support for policy scripts."

I am quite new to IDSs and have hardly touched Bro. But this work of packet
anonymization concerns my research area and if Bro provides such
functionality (or extensiblity) then I would love to explore it.
Can some Bro users point out to me if such an anonymizer is officially a
part of Bro, or maybe as a third-party plug in? My research concerns Deep
Packet Anonymization at IP layer and beyond for the headers and the
payloads for P2P networks.
