With various stories of factory products coming infected off the line, devious employees sneaking data to and from work or students using them to cheat, the security of USB on most systems has become a great concern. Some companies go so far as to disable USB on their workstations and prohibit bringing thumb drives inside the building. Among several companies, SanDisk is looking to help, and has schedule an announcement to be made at the RSA Conference in San Francisco. There, they will be demonstrating and pitching a security solution for USB:

"SanDisk will unveil a comprehensive solution for the enterprise security market, providing protection and control for USB flash drives," the company said in a statement.
According to Gartner, it's just an interim solution – one that will eventually pass SanDisk by, as products that exert more direct control over a machine and the software on it begin to take precedence.
