Elke was here

I am a physicist turned IT security engineer, or the other way around. I'll be in the nether land between communities and disciplines forever!

For about 15 years I worked exclusively in IT, my main specialty has been Public Key Infrastructure and X.509 certificates. Today I am also working on software development related to numerical simulations and measurement data analysis, and I am troubleshooting 'things' in the Internet of Things and their networking protocols.

My passion for debugging, sniffing, 'hacking', and reverse engineering is - for me - the natural connection and the overlap between experimental physics and IT security.

PKI in the real world, from my lecture given 2007-2011

I am learning to pentest!

What I have being up to - in the past quarter: As a long-term defender I wanted to learn a bit about actually hacking something - and I got sucked into the best black-hole ever! Playing and learning - combined in the best possible way!

One of those status updates - again.


PKI-Status-Update (2015-05-15)
Last year I was in PKI nostalgia mode, see this blog posting. for example. Accidentally (?), in 2014 several major PKI updates and migrations (from Windows 2008 (R2) to Windows 2012 (R2)) have been due.


PKI FAQ (2014-10-06)
I have started a new (another!) way to organize the Technet security discussion threads I have contributed to - sorting them by topics and categories I found useful in my own troubleshooting.

Trying to say what I do with PKI (again) as I am still getting project requests. I am supporting existing long-term clients only though.
