Ethics, Permission and Safe Practice
beginner 20 min 3 tasks
The most important rule in security: only test systems you have clear, written permission to test.
By the end of this lesson you can state the authorization rule, explain why testing without permission is illegal in most countries even with good intentions, describe what "scope" means, and explain why Purple Edge labs are a safe place to practise.
This lesson comes before anything hands-on on purpose. You must complete it before the lab in lesson 9 unlocks.
