Secure Data on Hard Disks
To extend the capabilities and functionality of our devices, Lexmark equips some of our printers and multifunction products with internal hard disks to store images of documents for job processing. Lexmark offers effective security controls to enhance the security of data that is stored on or passes through the hard disk, or to impede malicious users from gaining physical access to the hard disk.
Hard Disk Encryption
Hard disks in printers and MFPs can be configured to use encryption. An AES key, up to 256-bits, is internally generated by the printer or MFP and used to encrypt all data on the hard disk. The key is stored non-contiguously on the device, making the contents of the hard disk accessible only on the original printer or MFP. The data on a stolen hard disk would not be accessible even if the hard disk was installed in an identical model of printer or MFP.
Hard Disk Wiping
The data on a hard disk is sanitized so that no residual data can be read. Hard disk wiping can be configured for manual, automatic or scheduled mode. A multi-pass wipe is offered, which conforms to NIST/DOD standards.
Physical Lock Support
Lexmark printers and MFPs support Kensington-style locks, which allow the devices to be physically secured. Locking a printer or MFP also locks down the metal cage that houses the hard disk and other optional components, helping to prevent tampering or theft.
Non-Volatile Memory Wipe
The non-volatile memory wipe provides a tool for erasing all contents stored on the various forms of flash memory contained on the device. This feature is a complete clearing of all settings, solutions, jobs and faxes on the device. It was designed to be utilized when the Lexmark device is to be retired, recycled, or otherwise removed from a customer’s secure environment
