Capture The Flag (CTF) is a cybersecurity-focused game where teams compete against each other to capture “flags” that are hidden within puzzles.
CTFs are often played in “Jeopardy” format, where teams win by solving more puzzles than other teams, or puzzles with a higher weghted score.
Attack/defend CTFs take a more tactical approach, where opposing teams attack each others networks while simultaneously defending themselves from attack.
