Overview

Troubleshooting practice will help you develop the adversarial mindset that is essential for a cybersecurity analyst to have. Troubleshooting any situation helps prepare you to handle similar situations when they arise. The faster you can fix an issue, the less likely it is to cause harm throughout the event. In a sandbox environment, it is easy to experiment with causing and solving problems to test your peers or other members of an organization. You can also use a sandbox to challenge your skills and test your network defense competence. The GNS$3$ environment provides a virtual network that also incorporates host operating systems. The environment gives you the ability to interface with the operating systems of devices.

For this stepping stone, you will practice network troubleshooting in a sandbox environment. The sandbox is a safe place to practice your skills, as you won$$t have to worry about damaging a production environment. You will use the same sandbox environment for Project One.
