Thumbs Down on Thumb Drives

NEW YORK -- Where portable data's concerned, convenience has a cost -- a rather steep one if it's USB-based -- according to IT managers and CIOs attending an event here today.

"It's a disaster waiting to happen," warned Randy Kahn, principal of legal consultancy Kahn Consulting, in an address this morning. "The smaller it gets, and the more mobile it gets, the easier it is to lose the thing."

To illustrate his point, Kahn pointed to a recent report from the Committee on Government Reform, which painted a depressing picture of federal data security. As well as the highly publicized laptop loss at the Department of Veterans' Affairs, Committee members also cited the Department of Commerce which lost thumb-drives containing sensitive census records on 46 separate occasions between January 2003 and September 2006.

For Kahn, though, this may be just the tip of the iceberg. "How many thousands of thumb-drives were lost by the government over the last three years?" he wondered aloud. "Places need to have really stringent controls on how they use and how they manage" USB drives.

"It's a big challenge," agreed another speaker, Bob Venable, manager of enterprise systems at BlueCross BlueShield of Tennessee. "We're planning on banning USB drives at the start of January," he said, explaining that the threat of end-users introducing viruses via USB ports helped prompt this decision.

Despite recent enhancements from vendors, many execs are still wary of the security threats posed by USB drives. (See Lexar Locks Down USB Storage.) Some users are concerned that the software used to automatically boot up many USB drives could open the door to hackers, whereas others balk at the idea of staff losing critical corporate data.

Last month, for example, the Los Alamos National Lab hit the headlines when three USB drives containing sensitive data were reportedly found by police in the home of a lab worker. This latest storage snafu followed the supposed disappearance of classified defense secrets on portable floppies at Los Alamos a couple of years ago.

An IT manager from a major New York bank, who asked not to be named, told Byte and Switch that security fears have already prompted his firm to implement a tough USB strategy. "In our bank we have turned off the USB ports -- you're not allowed to access them unless you get authorization from the chief operating officer," he explained.

Even with this authorization, though, the bank only allows encrypted USB drives from two vendors, one of which is SanDisk, according to the exec. (See SanDisk Buys msystems.)

For BlueCross BlueShield's Venable, the move away from USB drives refocused his firm's vigilance of email as a way to share critical or sensitive data. By using a "reverse firewall" the insurer checks outgoing emails for sensitive corporate data such as customer lists.

The exec admitted that he still needs to work out some of the trickier details of his USB ban. "We will have to have exceptions because there are vendors that come in and want to bring in fixes via the USB port," he said.

Overall, according to Kahn Consulting's Randy Kahn, firms need to set up policies for auditing and monitoring portable media if they want to make their organizations more secure. Other key factors include staff training and communication. "Policies matter hugely -- they tell people what you expect from them," he explained.

At least one IT manager attending the event warned that, in reality, many firms are forced to compromise on the extent of their security strategy. "It's a question of money and the time that you have," explained Hossur Srikantan, CIO of U.K.-based online gaming company Blueberry Software. "You have to make a business decision based on that."
