About me

Hi, my name is Christian. I am living in Germany and currently work as an Security Expert in the defense sector. My day-to-day work is centered around the management and partial automation of multiple intrusion prevention solutions as well as the implementation of a honeypot infrastructure.

Previously I worked as an IT Security Analyst for a big European corporation. My day-to-day work involved a decent amount of incident response, a bit of forensics and automation, as well as the administration and operation of the vulnerability scanning and network anomaly detection environments. In the past I also worked as a Network & Security Engineer focusing on Firewalls, Data Center Routing & Switching (my favorite networking topic) and public cloud networking. I developed my interest in Security and Networking during my apprenticeship in IT systems integration.

The work I enjoyed the most at these positions was turning as much infrastructure as possible into code, and to then use that code to automate reoccurring tasks. The tools I use to accomplish this are mainly python, rust, ansible and gitlab for CI/CD. Sadly, most of my programs are tailored to fit my specific corporate environment, so sharing them does not make sense.

I am a big supporter of libre software and have been trying to remove as much proprietary software from my life as possible. Outside of tech, I took a liking to gardening, especially hydroponics, so you will see most about this on this blog too.
