The greater the number of protocols allowed active on the network the more vulnerabilities there will be available to be exploited. This also prevents accidental implementation of a “call-home” feature that is not allowed.
Checks: C-2941r2_chk

The reviewer will verify the configuration settings in the MFD or Network Printer to ensure the only protocol enabled is TCP/IP. If a protocol other than TCP/IP is enabled, this is a finding.

Access to the MFD or printer from outside the enclave network could lead to a denial of service caused by a large number of large print files being sent to the device. Ability for the MFD or printer to access addresses outside the enclave network could lead to a compromise of sensitive data caused by forwarding a print file to a location outside of the enclave network. This also prevents accidental implementation of a “call-home” feature that is not allowed.
Checks: C-2954r2_chk

The reviewer will verify that a firewall or router rule blocks all ingress and egress traffic from the enclave perimeter to the MFD or Network Printer. If a firewall or router does not block all ingress and egress traffic from the enclave perimeter to the MFD or Network Printer, this is a finding.

MFD devices or printers utilizing old firmware can expose the network to known vulnerabilities leading to a denial of service or a compromise of sensitive data. While the MFD must use the most current firmware available, it must not use a “call-home” feature that is not allowed.
Checks: C-2965r2_chk

The reviewer will verify that the MFD or Network Printer are flash upgradeable and are configured to use the most current firmware available. Ensure any “call-home” feature is disabled. If the MFD or Network Printer is not flash upgradeable, this is a finding. If the MFD or Network Printer is not configured with the most current firmware, this is a finding. If the MFD or Network Printer has the “call-home” feature enabled, this is a finding.

There are many known vulnerabilities in the SNMP protocol and if the default community strings and passwords are not modified an unauthorized individual could gain control of the MFD or printer. This could lead to a denial of service or the compromise of sensitive data. The SA will ensure the default passwords and SNMP community strings of all management services are replaced with complex passwords.
Checks: C-2966r2_chk

The reviewer will, with assistance from the SA, verify the default passwords and SNMP community strings of all management services have been replaced with complex passwords.

Fix: F-6434r1_fix

Develop a plan to coordinate the modification of the default passwords and SNMP community strings of all management services replacing them with complex passwords. Obtain CM approval of the plan and execute the plan.

Checks: C-2968r2_chk

The reviewer will verify the MFD or Network Printer maintains its configuration state after a power down or restart. Review the device documentation and/or confirm through demonstration to verify the MFD maintains configuration settings. If the MFD or Network Printer does not maintain its configuration state, this is a finding.

Since unrestricted access to the MFD or printer for management is not required the restricting the management interface to specific IP addresses decreases the exposure of the system to malicious actions. If the MFD or printer is compromised it could lead to a denial of service or a compromise of sensitive data. The SA will ensure devices can only be remotely managed by SA’s or printer administrators from specific IPs (SA workstations and print spooler).System AdministratorDCBP-1
Checks: C-2984r1_chk

The reviewer will, with the assistance of the SA, verify that the MFD or printer can only be remotely managed by SA or printer administrator from specific IPs (SA workstations and print spooler). Look for list that restricts the protocol used for administrative access to specific IP addresses.

Fix: F-6447r1_fix

Restrict access to the MFD's or printer's management function to a specific set of IP addresses. If the device lacks this functionality use an ACL in a router, firewall or switch to restrict the access.

If MFDs or printers are not restricted to accept print jobs only from print spoolers that authenticate the user and log the job, a denial of service can be created by the MFD or printer accepting one or more large print jobs from an unauthorized user. The SA will ensure MFDs and printers are configured to restrict jobs only to print spoolers, not directly from users. Mobile device print jobs must be sent to a print spooler, they must not be sent directly from a mobile device to a MFD or printer that supports direct wireless printing (e.g., AirPrint, Wi-Fi Direct, etc.). The configuration is accomplished by restricting access, by IP, to those of the print spooler and SAs. If supported, IP restriction is accomplished on the device, or if not supported, by placing the device behind a firewall, switch or router with an appropriate discretionary access control list. Client systems that are configured to bypass the print server that spools print jobs will lose access to the printer until reconfigured.
Checks: C-2998r4_chk

The reviewer will, with the assistance of the SA, verify that MFDs and printers are configured to restrict jobs only to print spoolers, not directly from users. If print jobs are sent directly to the MFD or printer, this is a finding. If direct wireless printing (e.g., AirPrint, Wi-Fi Direct, etc.), is enabled on the MFD or printer, this is a finding.

Fix: F-6461r2_fix

Reconfigure the device to restrict access, by IP, to those of the print spoolers and SAs. If the device does not support this functionality, place the device behind a firewall, switch or router with an appropriate discretionary access control list.

Department of Defense Manual 5200.01, "Protection of Classified Information" provides policy, assigns responsibilities, and provides procedures for the designation, marking, protection, and dissemination of controlled unclassified information (CUI) and classified information. DoDM 5200.01, Volume 3, Section 14 mandates that organizations identify equipment used for classified processing and develop security procedures to safeguard these devices. This requires that each organization have an MFD and printer security policy that lists the following safeguards: a. Prevent unauthorized access to that information, including by repair or maintenance personnel. b. Ensure that repair procedures do not result in unauthorized dissemination of or access to classified information. c. Replace and destroy equipment parts in the appropriate manner when classified information cannot be removed. d. Ensure that appropriately knowledgeable, cleared personnel inspect equipment and associated media used to process classified information before the equipment is removed from protected areas to ensure there is no retained classified information. e.

In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable unused or unnecessary physical and logical ports/protocols on information systems. MFDs are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Additionally, it is sometimes convenient to provide multiple services from a single component (e.g., email and web services); however, doing so increases risk over limiting the services provided by any one component. To support the requirements and principles of least functionality, the MFD must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved. Some network devices have capabilities enabled by default; if these capabilities are not necessary, they must be disabled. If a particular capability is used, then it must be documented and approved.
