Novel cyber incidents take so many forms. Practicing the application of tools and techniques against known cyber threats are a powerful and effective way to prepare cyber teams to take immediate actions in real-life situations. Capture the Flags (CTFs) is a popular style of cyber competition that lets operators exercise effectively. The major benefit of CTF competitions is the volume of learning attained by competitors during the timed and pressured activity, and the immediate reward following an achievement. Our challenging but fun competitions are designed around scenarios mimicking realistic situations and known vulnerabilities. Competitors are then given the opportunity to prepare against these types of threats in their own systems, reducing time to resolution and scale of impact. Competitions are useful to operators across diverse disciplines, including digital forensics, intelligence, communication, incident management and technical operations.
