The lesson

Accessing or testing systems without permission can be a crime under computer misuse laws in many countries, even if no harm is intended.

Authorised testing has written permission from the system owner, a defined scope, agreed times, named contacts and rules on handling data found.

If you discover a weakness in someone else's system, report it through their official channel (responsible disclosure) without testing further.

Step by step

  1. Read the lab rules.
  2. Identify what makes testing authorised.
  3. Write rules of engagement for a scan.
  4. Discuss three ethical dilemmas.

Practice activity

Write rules of engagement for the lab scanning exercise.

Expected result: Complete rules of engagement with scope, times, contacts and data handling.
