HackerLab 9000 (I call it
hal9k) will be a self-contained virtual hacker lab, capable of simulating dozens of systems on multiple interconnected networks.
The entire lab will be hosted on a single workstation. Lab users will be able to access the lab network via WiFi or ethernet. While connected, they will have access to the vulnerable lab systems, and also to the Internet (if the host is online). However, the vulnerable lab systems will not have access to the Internet. This protects against introducing vulnerabilities into a parent network.
If, in the future, I add additional lab subnets, I’d add them as
10.1.3.0/24, and so on.
