Retrofit gains certification for digital copier


A security retrofit for digital copiers from Sharp Electronics Corp. of Mahwah, N.J., has been certified under the Common Criteria for Information Technology Security Evaluation.

'Unless you have some way to erase the [copier] drive, there is going to be a latent image,' said Paul Kelley Jr., security specialist for the Army Research Laboratory's Security and Counterintelligence Office. 'Depending on the size of the drive, it could be hundreds of pages. We needed some way to ensure it was erased. That isn't something they can just throw on and say it works.'

Firmware works with four

The manufacturer-installed firmware overwrites the hard drive after each copy or print job. It works with four models from Sharp's digital imager series: the AR-287, AR-337, AR-407 and AR-507. They produce 28 to 50 pages per minute as workgroup copiers and also can serve as network printers.

Each model scans and stores documents on a 4.3G hard drive and prints them from the digital image. When used as a network printer, such a machine is a security exposure to anyone who obtains network access.

'This is the first time we've had to deal with [an office peripheral] that has a memory,' Kelley said.

Certification in April

The security retrofit kit has been available since mid-2000.

But the retrofit was not certified until April of this year. The Army Research Lab has ordered 31 of the kits for installed imagers, said Pete Cybuck, senior manager for product planning and marketing at Sharp.

The Common Criteria establish third-party evaluation procedures for security products that are recognized by 14 nations.
