Facebook made a Capture The Flag (CTF) cybersecurity competition open source and available this week  at https://github.com/facebook/fbctf .

There are several other CTF projects on github. I like that this approach to cybersecurity gets one thinking like an attacker. The problem is that the attack surface in highly connected systems is not obvious or easily modeled.

How about CTF competitions for IoT Security? There was one in March – http://www.wamda.com/memakersge/2016/04/challenges-possibilities-iot-big-data
