Community event format focuses on a more specific outcome and features training (Boot Camp basic training, dedicated lab), competition (Capture-the-flag or CTF), or both.
A typical CTF competition is an entertaining, educational and competitive format for individuals or teams, where participants have to complete a number of challenges. These can be suitable for your organization's cyber security professionals with complex technical challenges or toned down to be solveable to entry-level participants.
As an extension to this event format, technical challenges can be mixed with non-technical, e.g trivia, quizzes, puzzles or other content. This helps engage people in the event teams with mixed background and practise teamwork.
