Yesterday I wrote about moving autonomous-agent secrets out of a flat .env file. Why I kept Vaultwarden for people and recovery, added HashiCorp Vault for workloads, and treated identity, audit, PKI, and tested recovery as part of the deployment rather than follow-up work.
After years of working, teaching, writing in this field, the pattern I see most in newcomers is not lack of ability. It is freezing...
I spend my working hours telling teams how to do security well. Segment the network. Write the change down. Model the threat before you build the control. Then I go home, and if I am honest with myself, the temptation is to cut every one of those corners because it is "just the lab."
Welcome back to the Basics Series. In Basics Series - #3 we compared the firewall market, picked OPNsense for the lab, and installed it as a VM. In Basics Series - #4 we worked through the traditional vs. transparent-bridged decision and I promised a configuration walkthrough. This is that post...

Alongside the printed edition, the book's associated GitHub repository holds over 700 more pages of supplementary content and hands-on labs...
I'm thrilled to share that the second edition of the Cybersecurity Architect's Handbook is officially out in the world.
The Second Edition of the Cybersecurity Architect's Handbook: An Architect's Guide to Designing, Building, and Defending the Modern Enterprise is now available for pre-order on Amazon.
When the first edition of Cybersecurity Architect's Handbook: An End-to-End Guide to Implementing and Maintaining Robust Security Architecture hit shelves, the goal was ambitious but clear...
