Hackers and system failures

This article in the NYTimes is worth reading. Quoting the article:

Whether it’s the Los Angeles customs fiasco or the unpredictable network cascade that brought the global Skype telephone service down for two days in August, problems arising from flawed systems, increasingly complex networks and even technology headaches from corporate mergers can make computer systems less reliable. Meanwhile, society as a whole is growing ever more dependent on computers and computer networks, as automated controls become the norm for air traffic, pipelines, dams, the electrical grid and more.

“We don’t need hackers to break the systems because they’re falling apart by themselves,” said Peter G. Neumann, an expert in computing risks and principal scientist at SRI International, a research institute in Menlo Park, Calif.

Steven M. Bellovin, a professor of computer science at Columbia University, said: “Most of the problems we have day to day have nothing to do with malice. Things break. Complex systems break in complex ways.”
