Modern IT is built around the network, but the same connectivity that makes networked devices accessible to authorized users could put your network integrity and valuable information at risk without the technologies and safeguards built into devices from Lexmark.
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.
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.
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.
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.
Lexmark devices support the use of Secure Network Time Protocol (SNTP) to sync clocks of various devices on the network. To support the main requirement for an SNTP implementation, Lexmark devices support an Authenticator and Authorization field within our SNTP configuration.
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.
All LDAP traffic to and from Lexmark devices can be secured with TLS/SSL. LDAP information such as credentials, names, email addresses and fax numbers exchanged over a TLS/SSL connection ensures the information is encrypted to preserve the confidentiality and privacy of data.
