'Suicide nodes' defend networks from within - tech - 01 November 2007 - New Scientist Tech

"A selfless act of destruction – exemplified by the way honeybees die to defend their hive – has inspired a novel way of securing computer networks against malicious hackers. The approach works by giving all the devices on a network – or 'nodes' – the ability to destroy themselves, taking any nearby malevolent device with them. 'Bee stingers are a relatively strong defence mechanism for protecting a hive, but whenever the bee stings, it dies,' says Tyler Moore, a security engineer at the University of Cambridge in the UK."
