The D3FEND cube

All 272 techniques of the D3FEND catalogue as a city you can walk through: every row is a tactic, every pillar a base technique with its sub-techniques stacked on top. The cube starts with an entirely invented sample homelab. Under "Your homelab" you answer 27 short questions and see your own cube. Everything stays in your browser: nothing is sent or stored.

–

Drag = rotate · Shift-drag = pan · Wheel = zoom · Click = details · F = full screen

How meaningful is this? The questions rate whole groups of techniques at once and are deliberately coarse. They do not replace a technique-by-technique assessment, but they show within minutes which tactic holds your biggest gap. The Musterlab is invented and describes no real system.
