Prerequisite Knowledge

No specific knowledge or skills. Security cuts across all areas.


2014 was a hard year for open source software. The year was filled with Heartbleed, ShellShock, BERserk, and other vulnerabilities. These vulnerabilities were broadly discussed, even in news media that generally never cover these things such as CNN and Fox News. The question is, was this amount of attention really justified?

This presentation will take the data from the open CVE database and determine if there really is a striking change in the number of vulnerabilities, in either the frequency or severity of software security bugs, in open source software. We’ll also compare those two metrics to well-known proprietary counterparts.

This presentation will be extremely detailed on the data and be no-holds-barred when it comes to the direction that the data leads. Everyone will be able to see:

  • Has there been an increase in the frequency or severity of security defects in open source software?
  • Is open source or proprietary software more secure?
