Introduction

General Purpose and Audience

This document is intended to provide users of Xerox products accurate and actionable information to help them evaluate and manage risks associated with image data stored to disk drives or other non-volatile memory.

Summary Information

Xerox copiers, printers and multifunction products are devices that contain a computer and the necessary software that allows them to accomplish the many productivity-enhancing tasks that have become so valuable to today’s workplaces. These internal computers may have a disk drive or other non-volatile storage where job image data may be temporarily written during processing. Additionally, jobs may be stored for later reprint on some models. From the introduction of the first digital products, Xerox has recognized the risk of retained data being inappropriately recovered from non-volatile storage and built features and countermeasures into our devices to help customers safeguard their data.

Up to date product security information is maintained at www.xerox.com/security Information including security bulletins, patch information, US-CERT advisory updates, white papers, and videos on what customers can do to mitigate security risks can be found. Xerox provides detailed information about internal product workflows and features such as image overwrite in Information Assurance Documents which are available for many products at the website or as requested for older products.

Security Features

Jobs may be written to nonvolatile memory (e.g. to a hard drive) during processing. Generally, when a job finishes, this data is deleted, but may still be recoverable using forensic tools. Image overwrite is effective at eliminating this job data from the hard drive once the data is no longer needed. Xerox also scrambles the data with the user data encryption feature. This further protects data at rest from unauthorized access. Xerox recommends that the following features be enabled.

Fortunately, countermeasures are built into products to reduce this risk.

Immediate Job Overwrite or Immediate Image Overwrite is a feature that deletes and overwrites (with a specific data pattern) disk sectors that temporarily contained electronic image data. Products that use hard disk drives to store job data initiate this process at the completion of each job. This conforms to NIST Special Publication 800-88 Rev1. This should be enabled (and is by default on many products).

On Demand Image Overwrite is a manually initiated (can also be scheduled) feature that deletes and overwrites (with a specific data pattern) every sector of any partitions of the hard drive that may contain customer data. The device will be offline for a period of 20 minutes to one hour while this completes. This conforms to NIST Special Publication 800-88 Rev1. ODIO is effective as an extra protection step when the utmost in security is needed.

Disk or User Data Encryption is a feature which encrypts all partitions of the hard drive that may contain customer data with AES encryption. This should be enabled (and is by default on many products). Encryption can be used in combination with either overwrite feature.

Hard Drive Retention Offering is a service where, prior to a device being returned a Xerox technician can remove the hard drive and leave it with the customer. This program charges a flat fee per machine for the service. Contact Xerox Customer Support for information on fees and availability in your geography. There is a whitepaper describing this program on the Xerox Security website

Things to Remember

Not all products have hard disk drives. Those that do not are not at risk.

• Some products have hard disk drives, but do not use the hard disk drive to save document images. These are also not a risk.

• If a Xerox product is powered off before an Overwrite operation completes, there may be remnants of data left on the drive. A persistent message will appear on the device indicating the incomplete overwrite operation. In this event, it is recommended that an On Demand Image Overwrite be performed.

NOTE: Xerox strongly recommends the default Administrator password be changed on all devices to prevent unauthorized access to configuration settings.

Xerox does not offer sanitization or cleansing services for returned disk drives.
