We spend a lot of time thinking about hackers and abuse cases. This article entitled "Who Needs Hackers" by John Schwartz of the New York Times talks about how flawed systems, the increasing complexity of systems, and even mergers and acquisitions can make computer systems unreliable. The rush to market can lead to not enough testing. Pressures to ship software and hardware quickly and to keep costs at a minimum work against more secure and robust systems. These are the same pressures that lead to the flaws that hackers take advantage of as well.
