Paul Vixie On the Unevenly Distributed Intelligence of Internet Infrastructure 96

CowboyRobot writes "Writing for ACM's Queue magazine, Paul Vixie argues, "The edge of the Internet is an unruly place." By design, the Internet core is stupid, and the edge is smart. This design decision has enabled the Internet's wildcat growth, since without complexity the core can grow at the speed of demand. On the downside, the decision to put all smartness at the edge means we're at the mercy of scale when it comes to the quality of the Internet's aggregate traffic load. Not all device and software builders have the skills and budgets that something the size of the Internet deserves. Furthermore, the resiliency of the Internet means that a device or program that gets something importantly wrong about Internet communication stands a pretty good chance of working "well enough" in spite of this. Witness the endless stream of patches and vulnerability announcements from the vendors of literally every smartphone, laptop, or desktop operating system and application. Bad guys have the time, skills, and motivation to study edge devices for weaknesses, and they are finding as many weaknesses as they need to inject malicious code into our precious devices where they can then copy our data, modify our installed software, spy on us, and steal our identities."
