Built, Broken, Fixed: BIBIFI Security Contest Report

Earlier in the summer I discussed a security-oriented programming contest we were planning to run called Build-it, Break-it, Fix-it (BIBIFI). The contest completed about a week ago, and the winners are now posted on the contest site, https://builditbreakit.org.

Here I present a preliminary report of how the contest went. In short: well!

We had nearly a dozen qualifying submissions out of 20 or so teams that made an attempt, and these submissions used a variety of languages — the winners programmed in Python and Haskell, and other submissions were in C/C++, Go, and Java (with one non-qualifying submission in Ruby). Scoring was based on security, correctness, and performance (as in the real world!) and in the end the first two mattered most: teams found many bugs in qualifying submissions, and at least one team was scoring near the top until other teams found their program did not pay much attention to security.

We have much data analysis still to do, to understand more about what happened and why. If you have scientific questions you think we should investigate, after reading this report, I’d love to know them. In the end, I think the contest made a successful go at emphasizing security is not just about breaking things, but also about building them correctly.
