The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

Perhaps it was carving a pathway through the Amazonian rain forest during your gap-year trek? Or was it a Sunday morning spent wrestling with the shears in an effort to make your garden-privet resemble a cockerel? If you were teenager Raphael Gray, then your last hacking endeavour was certainly memorable. Why? Because it resulted in American FBI agents rapping on the door of his home in deepest Wales, one frosty morn in March. The young fool's crime was to hijack the details of some 23,000 credit cards from the databases of numerous online retailers using nothing more than a basic home computer and a modem. Gray considered himself a "saint of e-commerce" whose mission was to expose online security holes, but the media were quick to label him a hacker - and it stuck The link for this article located at VNUNet is no longer available. .

It was a common enough problem for a small business: AMT Asset Management, a Marlboro, New Jersey-based brokerage with six employees, needed a way to connect its Boca Raton, Florida office to headquarters. The goal was to provide the smaller office access to the Web-based securities-pricing information that amt was already receiving at its New Jersey location. That way, amt could avoid having to subscribe to a separate outside data provider just for the Florida office--for upwards of $1,200 a month. The obvious solution would have been a secure virtual private network--in this case, essentially a broadband pipe through a telecommunications carrier--linking the two sites. But when amt president Jeffrey Gerstel, who doubles as the company's technical support, explored this alternative, he saw that it wasn't really an option at all. Quotes that ranged as high as several thousand dollars each month scared him off. "We spoke to a few network companies, and the solutions were very expensive," says Gerstel. A vpn was simply too pricey for his tiny company. The link for this article located at ZDNet is no longer available. .
