A framework for organising and holding security conferences. Concept began in the US - believe around 2009 with Mike Dahn, Jack Daniel and some others. Believe it emerged because the CFP for Blackhat Vegas or DEFCON was oversubscribed and those unable to present decided to hold their own conference on the 'b side'. Have now been arranged in many countries throughout the world. Has become known as a 'conference by the community for the community'. Events are generally free to attend and rely on sponsorship to pay for the venue and other costs and are run as not-for-profit.
