In the next version of Windows, Microsoft will give big companies an easy way to block use of iPods and other portable storage devices, while making it easier for consumers to connect their home systems to them.
Much has been made of the security risks posed by portable storage devices known as USB keys, or flash drives, music players like the iPod, and other small gadgets that can store vast amounts of data. Some fear that such tiny devices can be used to quickly copy sensitive data off business PC hard drives, or to introduce malicious software onto corporate networks.
"It's a real problem," said Padmanand Warrier, a developer in Microsoft's Windows unit. "That's the feedback we've got from IT folks."
To put the new features in place, Microsoft is hoping to move to a common model for how wired and wireless devices connect to a PC in 2006, around the time that it releases the next version of Windows, code-named Longhorn. For consumers, that means that wireless printers, networked music players and other wireless devices should be able to connect to a PC as easily as the USB drives today.
Microsoft did include a workaround in Windows XP Service Pack 2 that lets users change an internal Windows setting to prevent data from being written to USB devices. But the features planned for Longhorn will be more comprehensive.
Microsoft showed its future technology, known as "Plug and Play Extensions", at this week's Intel Developer Forum.
For businesses, it means regaining some control over portable devices. "It's not just USB keys," Warrier said, noting that devices can just as easily link to PCs through Bluetooth short-range wireless or another connection.
By including tools to prevent workers from connecting portable storage devices to corporate PCs, Microsoft is offering big companies another option in addition to the outright banning of such devices, as some government agencies and other high-security installations have done.
"USB keys have become ubiquitous," said, Alan Brill, a senior managing director at Kroll OnTrack, a technology services firm that does security consulting. "You can pop them into any computer after Windows 95 and all the software that's needed is already in there. It's a tool that can be both used and abused very easily."
Companies have been slow to react to the threat posed by digital storage devices in general, Brill said.
"It's one that companies have turned a blind eye to for a very long time," Brill said. "If you think back, it used to be that stealing significant secrets was difficult because it was hard to get away with that much paper."
Intel, for example, used to check the bags of employees, but eventually such searches became impractical. With roughly, 80,000 employees, the company found it didn't have the resources to prevent against someone putting files onto a flash drive or iPod, a representative said.
Research firm Gartner has advised big companies to disable certain "plug and play" functions in Windows as a security precaution.
