About

I am Damián Muraña, an information technology professional focused on IT infrastructure, networking, information security, and cloud computing. I have been working in the field for over a decade, having held diverse roles: systems administration, infrastructure design and implementation, cybersecurity, and solutions architecture.
This blog was created as a technical space to organize ideas, document learnings, and think out loud about technology. It is not intended to be a definitive manual or a catalog of “best practices,” but rather a working notebook: notes on networking, security, GNU/Linux systems, cloud computing, and modern architectures, occasionally combined with more conceptual reflections.
I am interested in technology beyond trends and sales pitches. I prefer to understand how systems work, what their limits are, and what decisions—both technical and political—lie behind them. From a technical perspective, I value simple, maintainable, and well-thought-out systems. From a cultural perspective, I advocate for free software, open culture, and access to knowledge as tools to build more ethical, accessible, and sustainable technology—you will see me write a lot here about open technologies, though not exclusively.
On Drop the firewall, I share notes, analyses, and reflections on networking, security, Linux, cloud computing, and other technologies of interest, aiming to consolidate my own learning and spark discussion. I believe in the internet as a space for knowledge exchange, and this blog is my contribution to that dialogue.
If you’ve made it this far out of technical affinity, curiosity, or chance, welcome. This blog is meant as an open conversation, and I invite you to join in.
