Security Features of Lexmark Laser Printers: Overview

Executive Summary

Printers are complex network devices that require careful consideration regarding security. Lexmark’s printing and networking products include a wide array of security related features. This document discusses those features and provides an overview of their benefits and their implementation.

Any device that is placed on a network must be evaluated with respect to security. How does the device protect itself from unauthorized access? Does the device expose the network to any form of vulnerability? What sort of information does the device process, and what are the security considerations related to that data? These and many other questions are appropriate to ask of any networked device, including networked printers.

Networked printers operate independently on the network and can be focal points for sensitive information. Securing them is sometimes comparable to securing other conventional networked devices such as computers: the need for controlled network access and the need for secure remote management are largely the same for printers and workstations. In other areas, the security considerations around printers are substantially different: they generally don’t run conventional operating systems, they don’t have network file shares that need to be secured, they probably don’t need or support antivirus software, etc.

This document will define the major areas of security concerns related to printers, and provide an overview of the security features of Lexmark’s printers that allow the devices to be deployed, managed and used in a secure manner.
