Observations From an Online Security Competition and Its Implications on Crowdsourced Security

The crowd sourced security industry, particularly bug bounty programs, has grown dramatically over the past years and has become the main source of software security reviews for many companies. However, the academic literature has largely omitted security teams, particularly in crowd work contexts. As such, we know very little about how distributed security teams organize, collaborate, and what technology needs they have. We fill this gap by conducting focus groups with the top five teams (out of 18,201 participating teams) of a computer security Capture-the-Flag (CTF) competition. We find that these teams adopted a set of strategies centered on specialties, which allowed them to reduce issues relating to dispersion, double work, and lack of previous collaboration. Observing the current issues of a model centered on individual workers in security crowd work platforms, our study cases that scaling security work to teams is feasible and beneficial. Finally, we identify various areas which warrant future work, such as issues of social identity in high-skilled crowd work environments.
