      Lots of people using "sparse" vs "dense" to reason about vulnerability research recently, but I'm not convinced that it's a useful exercise

      As I understand it, deciding if something is sparse or dense is almost entirely subjective, and you're describing a single point in time.

      I think it's almost always more useful to look at the ratio of bug fixes versus introduction: i.e. are we trending towards "less dense"?

      @benhawkes I tried to pick this apart in a post to dailydave using vsftpd as an example. https://lists.immunityinc.com/pipermail/dailydave/2014-November/000813.html …

      @benhawkes I think you're nearly right, it has everything to do with pace of software development. When feature dev slows, bugs trend down.

      @benhawkes this is easy to grasp when you look at sw written against a spec, like FTP. It's just "done" at some point.

      @dguido I'd add that thoughtful compartmentalization can give a defensible (limited+stable) attack surface even where dev velocity is high.

      @dguido Primarily I just wanted to unpack the "bugs are dense so VR doesn't matter" idea in to something that can be concretely debated.

      @benhawkes yeah that's a silly thing to say, even though bug finding has been over emphasized as a defense. IMHO stems from offense envy.

          @dguido @benhawkes bug finding is overrated as a defence (obvs not completely useless), but fetishizing bugs is an industry wide problem
