desvert's blog

I'm a commercial HVAC technician working toward a career in cybersecurity. This blog is where I document the work: building OT control systems and then figuring out how to break them, working through CTFs and wargames, and occasionally running a small service the right way just to see what that takes.

Selected Projects

• Containerized Bedrock Server
  Dockerized Linux service with automated backups and configuration enforcement.
• OT HVAC Testbed
  HVAC control and instrumentation testbed used to explore real-world OT/ICS concepts.
