SSL Tidbits at the BASTA.NET

A while a go Dominik and I gave an introductory presentation about SSL at the BASTA.NET conference, a developer-oriented event held in Darmstadt twice a year. At that time there were quite some enthusiastic participants but recently we’ve also gotten some inquiries asking for the relevant materials. Although there’s no recording of the session, we’ve decided to put the slides here for those interested who didn’t make it to the talk.

“Who should have a look at the slides?” you ask, well, if you’ve been wanting to get a sense for what the idea behind SSL is, where it is used, how it is usually leveraged and what problems could arise when poorly employed, you will certainly find the slide-deck interesting. Although the session was meant to slowly get participants up to speed in matters SSL, it’s still likely that more informed folks will still find it interesting, even if just as a refresher about key and certificate formats, PKI 101, SSL stripping, secure cookies, and other topics.

Without further, here’s slide deck.

For the hungry, here are some other interesting resources we suggested to attendees willing to go a bit deeper on the topic after the talk.

OWASP – SSL für Alle
OWASP – Transport Layer Protection Cheat Sheet
Mozilla – Server Side TLS

For those attending to the BASTA.NET next autumm, we’re looking forward to meeting you. But for the time being, that’s going to be pretty much it.

Thanks for reading and let us know what you think.

BASTA! Spring 2013

Yesterday I was giving two presentations about Cloud security at the BASTA! Spring 2013 Security Day. While my presentations covered Microsoft Azure security considerations (which also included a part of the Cloud security approach covered in our workshops; slides available here) and some major Cloud incidents (suitable to transport different messages about Cloud security in general ;); slides available here), I also saw Dominick’s very interesting presentation about security aspects and changes in Windows 8. Inspired by that, we hope to be able to publish another blogpost on those aspects with regard to enterprise environments soon — most likely we won’t find any time for it before TROOPERS 😉

Have a good one,

Some recent presentations

Just a short notice today on some recent presentations from our team. As some of you might know we regularly give talks at conferences. This not only encompasses highly sophisticated security events like Black Hat or Troopers. Additionally – on our mission for a safer world – we try to spread the (security) word at various industry events that are usually focused on some aspect of the large and ramified IT world, not necessarily equipped with a strong focus on information security.
A number of such events took place in the last few weeks and here’s some links on presentations given there. While not being as technically deep as the average Black Hat or Troopers attendee might expect, we still hope that one or another valued reader finds them useful (pls note that some parts are in German).

This one is a talk given by myself on “Compliance in the Cloud” in the course of the “Azure Day” of BASTA which is one of the largest and most important developer events here in Germany. The presentation discusses what to keep in mind if compliance with some “regulatory frameworks” is strived for when going to “the [public] cloud”.

Here‘s a piece on virtualization security, namely the architectural changes on basic security principles induced by (server) virtualization. It was provided at the “IIR Admin Tech Talk 2010” and, again, I myself was the speaker.

Rene Graf, who’s a member of the “Architecture and Risk Team” at ERNW and a long-time large-environment security guy, gave this overview talk on “Industrial Firewalls” at the LANline TechForum “Industrial Ethernet” which took place in Stuttgart.

Last but not least, Matthias Luft (being another member of the same team and pursuing his academic career in parallel) delivered this talk on DLP at ISSE in Berlin, together with Thorsten Holz.

Have a great day everybody,


Btw: our next stop will be at fabulous Day-Con. If any of our readers from the US – very appropriately – is worried about missing it, pls shoot me an email. Given our long term friendship with Angus we might be able to provide you a ticket.
