Teaching & Labs

Hands-on lab builds and teaching material: home labs, SOC environments, AD setups, and hardening guides, written to be followed, not just read.

Every guide here is run end-to-end before it publishes: each stage ends with a verify step, every command shows its expected output, and the "what can go wrong" table comes from mistakes actually made while building it. That is why the list below is short. It grows one verified lab at a time.

Available now:

• Reset a Lost Root Password: recover root access to a Linux system from the bootloader, and understand why physical access changes the threat model.

More labs are in progress and will land here as they pass the run-it-yourself bar.
