It comes in many formats, some require you to solve a question before moving on to the next, others are jeapordy style where you can choose any question among different categories at any time. If you like solving puzzles or following clues to find a root cause then these are great exercises.

If you've read this far and you have no idea what a CTF is, then kudos to you. In short CTF stands for Capture The Flag, you're given a question and often an artifact or piece of evidence and have to answer the question.

A lot of cybersecurity cons run CTF competitions, the recent virtual PancakesCon (pancakescon.com) offered a CTF.

You can find a list of upcoming CTFs at ctftime.org
Also MetaCTF (metactf.com) runs some short notice Flash CTFs.

If you have done CTFs then it's a great talking point in an interview. Here are some of the slightly more casual/accessible CTFs:
nationalcyberleague.org (HS and college)
www.uscyberpatriot.org (HS level)
www.sans.org/cyber-ranges... (non-competitive)
National Cyber League Webpage
The NCL is a learning-centered cybersecurity competition and community for high school and college students.

Check local city/county/state govt for opportunities if you're not geographically flexible. Also orgs for local services (water, energy, internet). Students at a university or community college check departments involved in cybersecurity ed they may have local relationships.

Their CTF is with SANS so a good opportunity to engage in a competition and chat about it here after the CTF is done. Join the PancakesCon slack channel, they will release the registration code there. #sans #pancakescon
