A moderated discussion on how to hack policy systems using laws and authorities already on the books, featuring the policymakers who write and use them, focusing on open source and software security. At DefCon 22 in the aftermath of Heartbleed, John Menerick told us to "keep calm and hide the internet". Alas, they found it. The policy community in the US, and lesser extent Europe, is finally starting to put serious focus on software security including open source. This event will bring hackers together with policymakers to identify policies on the book that could help improve the open source ecosystem and the security of software. Other policy conversations might stray into the possible, this one will emphasize the practical. The discussion will involve policymakers who write and implement these laws and use these authorities to enable discussion and debate focused on pragmatic solutions, putting hackers inside ongoing policy debates in real time.
