Why You Need a Lab
The one place where breaking things is legal: what a lab is, and why every other lesson depends on it.
Choosing Virtualization
A hypervisor turns one computer into many. What it is, type 1 versus type 2, VirtualBox against VMware against UTM against Hyper-V, and how much RAM the host can really spare.
Networking Your Lab
The four virtual network modes, and how to wire an attacker box to targets that can never reach the internet or the house.
Stocking It With Targets
Where deliberately vulnerable machines and apps come from, how to check the file that arrived is the one that was published, and which to reach for first.
Snapshots and Safe Habits
Snapshot before you break it, keep notes on the host, keep real credentials out, keep the lab sealed, and rebuild anything you can no longer trust.
