Welcome to Insinuator.net 2.0

It’s almost exactly seven years since Enno published the very first blog post on Insinuator.net. Meanwhile, quite a few things changed. It’s not only the ERNW Universe which grew significantly, but also Insinuator’s place within this universe was slightly adjusted. What started as an almost independent IT-Security blog became more and more the major publication medium of ERNW.

I recently had the pleasure to join the 64th NANOG (North American Network Operators’ Group) meeting in San Francisco, which can be understood as one of the largest Internet engineering conferences at all. It takes place three times a year at different locations in North America.

What I personally like about NANOG is its strong collaborative and cooperative character. It is not about single persons and also not too much about spectacular projects but more about discussing technologies, ideas, challenges and numbers. Every talk has a comparatively large time slot reserved for discussion, which is often more than fully used. Discussion is typically actively focused and is more time-consuming (and even more relevant) than the talk itself. Which often is intended by the community. The climate of discussion is almost always impressively polite and constructive, even for controversially discussed topics.

A Wrap-up on MFD Security

On last year’s TROOPERS11, Matthias (mluft) and I gave a talk on Multifunction Devices. Hardly surprising: It was related to the state of secure operation of MFDs. It was heavily motivated by experiences we collected out in the wild. We faced a frightening low level of awareness concerning the role of MFDs for the overall security picture – in particular regarding the processing of sensitive data…

However, instead of only showing and proving well-known weaknesses and vulnerabilities, we decided to adapt ERNW’s Seven Sisters model in order to match the needs of secure MFD operation and to develop some kind of guideline. As Matthias already lost some words on this, I’m not gonna waste your valuable time by repeating, what has already been said. However I described our approach and our thoughts on that topic in a recently published ERNW Newsletter. If for what ever reason you didn’t see our talk or even didn’t attend TROOPERS11 at all, have a look on Newsletter 37 and give us feedback on what you think about the whole topic…

Btw: Enno just wrote some lines about what’s so special about the TROOPERS conference. In case you might want to discuss mentioned and related topics at first hand, think about joining TROOPERS12. For our part, we cannot wait to come together at Heidelberg next March.

See you there
