CTF are known as Capture The Flag competition. CTF’s are game designed for students, and professionals which teaches Information Security by asking them to solve challenges which are created in a safe and enclosed environment. In a regular jeopardy style CTF competition, there are various categories – such as – Web, Mobile, Cryptography, Forensics, Binary (some organizers call it as pwn), Reverse Engineering, Misc. There are usually challenges which vary from different points within such categories. Once, a team or individual solves them, they validate a flag which proves they indeed solved it and receive points. The team with highest points under defined amount of time is declared winner. It is a very fun way to learn cybersecurity within enclosed environment. CTF’s for an Information Security Enthusiast is an equivalent of competitive programming (ACM) for a developer. 🙂
