Anti-botnet vendors plug in

A small group of IT security startups are hoping to cash in on the rise of the botnet scourge as businesses -- telecommunications carriers and Internet service providers, in particular -- seek new methods for stopping the attacks.

While larger security software makers, including Symantec, McAfee, and Trend Micro, have built botnet-fighting functions into their existing products, and carrier security specialists such as Arbor Networks have added tools for detecting the threats in their network monitoring systems, a handful of smaller companies are attempting to market themselves as purists in the anti-botnet field.

As carriers, ISPs, and large enterprises investigate techniques to keep computers on their networks, and those of their customers, from being recruited into the zombie armies of botnet-controlled devices, some experts say that there may be a market for stand-alone technologies that address the problem -- at least for the next several years.

"If you look at the change in the characteristics of malware attacks over the last year, and the public outrage over data breaches, private and government organizations have reached a point where the botnet issue is directly accessible," said Nick Selby, analyst at The 451 Group.
