This is the intention of Paul Barford, a computer scientist at the University of Wisconsin-Madison. He wants to build a new line of defense against malicious traffic which has become today a billion-dollar 'shadow industry.' As one of 'the most menacing aspects of botnets is that they can go largely undetected' by a PC owner, he developed a new computer security technique for detecting network intrusions. His system has a 99.9% detection rate of malicious signatures, roughly equivalent to some of the best commercial systems. But it has zero false positives when commercial systems have high numbers. This new system could soon be available commercially.
Security specialist Symantec has warned businesses over an increasing trend for criminals to use "parasitic storage" on networks of compromised systems.While botnets -- illegal networks of PCs infected with remote software by hackers -- are used mainly for sending spam, criminals are increasingly storing sensitive or illegal data in distributed environments, the security company told our sister site ZDNet UK on Tuesday.
