The best answer, Dr. Neumann says, is to build computers that are secure and stable from the start. A system with fewer flaws also deters hackers, he said. “If you design the thing right in the first place, you can make it reliable, secure, fault tolerant and human safe,” he said. “The technology is there to do this right if anybody wanted to take the effort.” He was part of an effort that began in the 1960s to develop a rock-solid network-operating system known as Multics, but those efforts gave way to more commercially successful systems. Multics’ creators were so farsighted, Dr. Neumann recalled, that its designers even anticipated and prevented the “Year 2000” problem that had to be corrected in other computers. That flaw, known as Y2K, caused some machines to malfunction if they detected dates after Jan. 1, 2000. Billions of dollars were spent to prevent problems. Dr. Neumann, who has been preaching network stability since the 1960s, said, “The message never got through.” Pressures to ship software and hardware quickly and to keep costs at a minimum, he said, have worked against more secure and robust systems. “We throw this together, shrink wrap it and throw it out there,” he said. “There’s no incentive to do it right, and that’s pitiful.”
