Capture The Flag is both fun and educational at the same time, and a great tool to raise security awareness. You can do it by yourself, together in a team, or in competition mode against others.
The OWASP Juice Shop is a site that you can set up and use for this. It has a great Tutorial mode for beginners and a lot of challenges at all different levels as well as a scoreboard where you can track your progress. You can also set up a scoring-server for competitions, like getting the highest score or doing it jeopardy-style.
In this session, you will learn how to set it up, and how it works, and get a kickstart on the hacking. After this session, you will have the knowledge to host your own CFT event.
