Network Protections

Network safeguards built into devices from Lexmark

Make your print fleet a no-hacking zone

Properly configured, features supporting network security can protect Lexmark devices from unauthorized access. From disabling unnecessary features to locking down device interfaces and securing the data they contain, Lexmark devices include a range of embedded features to help you harden a device against attacks. It’s a powerful way to secure network interfaces from malicious users.

Secure remote management provides a wide range of tools and device capabilities to effectively manage a fleet of networked laser printers and multifunction products. You can restrict device management to authorized personnel and secure your device settings through a combination of rigorously enforced device access, audit logging, digitally signed firmware upgrades, certificate management, HTTPS, SNMPv3 and secure password reset.

Carefully engineered hard disk security equips Lexmark printers and multifunction products that contain internal hard disks to keep your organization's secrets. This shield of protection both enhances the security of data stored on the hard disk and helps prevent malicious users from gaining access to confidential information.

TCP connection filtering

Printers and MFPs can be configured to allow TCP/IP connections only from a specified list of TCP/IP addresses. This disallows all TCP connections from other addresses, which protects the device against unauthorized printing and configuration.

Access controls

Control local and remote access to specific menus, functions and workflows on each device. Entirely disable functions like copy, print, fax, scan to email, FTP, held jobs and address book. Over 50 access controls are available, providing greater flexibility for your unique environment.

Port filtering

The network ports through which printers and MFPs listen for or transmit network traffic are configurable, allowing a huge degree of control over the device’s network activity. By filtering out traffic on specific network ports, protocols such as telnet, FTP, SNMP, HTTP and many others can be explicitly disallowed.

802.1x

With 802.1x port authentication, printers and MFPs can join wired and wireless networks by requiring the devices to authenticate prior to accessing the network. This authentication can be used with the Wi-Fi Protected Access feature of an optional wireless print server to provide WPA Enterprise security support.

Fax/network separation

Lexmark offers a variety of MFP devices that provide both network connectivity and fax modem capability. And to prevent any direct interaction between the modem and network adapter, Lexmark device hardware and firmware keep these mechanisms separate.

IPSec

The IPsec protocol option, when enabled, secures network traffic to and from Lexmark devices with encryption and authentication. This protects print data and the contents of jobs that are scanned to any destination, including servers running Lexmark Document Distributor, email, and network storage.
