<Can We Make Operating Systems Reliable and Secure?><\/strong> When was the last time your TV set crashed or implored you to download some emergency software update from the Web? After all, unless it is an ancient set, it is just a computer with a CPU, a big monitor, some analog electronics for decoding radio signals, a couple of peculiar I\/O devices (e.g., remote control, built in VCR or DVD drive) and a boatload of software in ROM.<\/p>\n This rhetorical question points out a nasty little secret that we in the computer industry do not like to discuss: why are TV sets, DVD recorders, MP3 players, cell phones, and other software-laden electronic devices reliable and secure and computers not?<\/p>\n …<\/p>\n
