Bold Statements
Flo and I had the pleasure to present at the CSA Nordic Summit in Norway. Being in Oslo for the first time, we enjoyed the conference (small, familiar atmosphere) very much and want to thank Lars and Kai for putting together such a good event & having us there!

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.

By default IIS implements a lot of basic security measures, but are these the relevant ones to protect your business? Continue reading “Internet Information Service 7.5 Hardening Guide”
Continue readingIn the course of a customer project I recently documented some thoughts and general objectives of IPv6 address planning, expanding on stuff I wrote a while ago in the series on “Address Plan Considerations”. An excerpt of that (newer) document can be found here. Due to the context it originates from it’s in German, still I hope it’s useful for some readers.
If you’re interested in the topic it might be a good idea to listen to Tom Coffeen‘s talk at the upcoming IPv6 Business Conference, too.
Everybody have a great day

I wrote a small python script that extracts the content from Alcatel .tim firmware files. It took some time staring at hex values, as well as a fair amount of guess work to figure out the file format.

There has been, again, some development within the loki domain. Today I’m going to write about the latest module added to the suite, a module for decoding and cracking Cisco’s TACACS+.

End of May eight ERNW members were travelling to Moscow (Russia) to visit the PHDays V conference. It was a very nice trip because we met a lot of gentle people, ate some great food and had quite some fun in this exciting and history-charged metropole, and we were able to get around using hands and feet (and Google translate ;-)).
The remainder of this post contains summaries of some of the most interesting talks at PHD V:

I’m back from London where I gave a talk about security evaluation of proprietary network protocols. I had a great time at InfoSecurity Intelligent Defence and BSides London, many thanks for inviting me and giving me the opportunity to speak to so much nice people.
Find the abstract and the download link to the slides after the break.

Continue readingScott Hogg recently (in his post “Holding IPv6 Neighbor Discovery to a Higher Standard of Security“) gave the following answer:
“The security of IPv4 is roughly equivalent to IPv6. So why do we expect more from IPv6?”
While I highly value Scott’s IPv6 expertise – not least because I learned a lot about IPv6 security from the book on the topic he wrote together with Eric Vyncke – I strongly disagree with his statement, mainly with the first part. In this post I will lay out why I think that IPv6 is actually less secure than IPv4.

Continue readingToday the ERNW Team participated in the Mudiator mud race in Mannheim. This mud run features 25 obstacles over 8 km, you can do either one or two rounds. Participating for the first time, the ERNW team went for one round (the Legionnaire distance as opposed to the two round Hercules distance):
