Capture The Flag (CTF) is a specially designed strategic war-game that mimics the real world security challenges. Each team is given a machine (or small network) to defend on an isolated network. The teams need not be physically present at a central venue. They can connect their networks to game network through a Virtual Private Network (VPN). Teams score based both on their success in defending their assigned machine and their success in attacking other team’s machines.

Each team needs to exploit the custom application services running at each team’s side. A team gains points by submitting the flags of other teams. Unethical behavior(for instance, bringing another teams machine down) is allowed. However, you will lose points for it.
