As part of my contribution to the Honeynet Project, we have released the forth instalment in the "Forensic challenge" series. This challenge is focused in the world of VOIP telephony, which is a burgeoning area and one that is unfortunately often neglected when it comes to security treatment, and in particular in the study of the threat/incident environment. I've been studying the threat environment for over 18 months, working closely with the Norwegian chapter - you can read about some of this work in my honeynet blog.

The "VOIP forensic challenge" consists of real world attack data, and poses some technical and reflective questions which challenge participants to piece together the clues, and discover some hidden attributes of the attacks. Participants will learn much about VOIP along the way, and as a result they will be better armed to mitigate the risk of attacks to VOIP systems.

For the first time, we have translated the challenge into Chinese - both Traditional and Simplified versions. This will make the challenge accessible to an additional billion people. We are very excited about this, and are hoping for unprecedented participation. In designing the challenge, we formed a team with members from Norway, Hong Kong, China, Taiwan, Singapore, France and the US. I'm continually impressed by the collaborative global environment that exsists at the Honeynet project.

If you are in a position to advertise the challenge to students or security teams - please feel free to do so. Remember the goal is to participate, enjoy and learn!
