"When you design something or build something with security in mind, you
are always cognizant of the fact that you can have ten measures and if
everything works fine, that's great. But on the other side, the other
person needs to succeed just once! Whatever ten things you have that is
successful, is done away with this one failure. Well that is the story
in the proprietary perspective. In the open source perspective,
everything that we build is completely transparent. Everybody knows what
we are building."
