What is a Capture the Flag (CTF) event?¶
Capture the Flag Overview¶
A Capture the Flag (CTF) event is a computer security competition, usually held by an educational sponsor. There are many CTF formats, including Jeopardy Style, Attack/Defense, Red Team/Blue Team, Network/Host Forensics, etc., covering a wide array of security related topics from host based security, programming/scripting, system administration, reverse-engineering, to network sniffing, WiFi hacking, protocol analysis, and cryptography.
Attack/Defense CTFs are usually run in virtualized environments, use desktop virtual machine software such as VMWare, or are run in restricted network labs as they can be somewhat unruly and dangerous to host on live office or school networks. This is where the U.S. Cyber Range really shines.

The U.S. Cyber Range has pre-configured Jeopardy style, web-based competition environments that can host hundreds of simultaneous users. As a CTF Admin, you can create these environments from within the Exercise Area of the U.S. Cyber Range. Our CTF platform, called Cloud CTF, is designed to safely host CTF events that will allow your students to compete and learn in a fun and effective way. For a quick overview of Cloud CTF, please see the article titled Cloud CTF Overview.
