Interfaces

Xerox® Security Guide for Office Class Products: AltaLink® VersaLink®
November 2018 Page 7
User Interface
The user interface detects soft and hard button actuations and provides text and graphical prompts to the
user. The user interface is sometimes referred to as the Graphical User Interface (GUI) or Local UI (LUI)
to distinguish it from the remote web server interface (WebUI).
The user interface allows users to access product services and functions. Users with administrative
privileges can manage the product configuration settings. User permissions are configurable through
Role Based Access Control (RBAC) policies, described in section 7Identification, Authentication, and
Authorization
Scanner
The scanner converts documents from hardcopy to electronic data. A document handler moves originals
into a position to be scanned. The scanner provides enough image processing for signal conditioning and
formatting. The scanner does not store scanned images.
Marking Engine
The Marking Engine performs copy/print paper feeding and transport, image marking, fusing, and
document finishing. The marking engine is comprised of paper supply trays and feeders, paper transport,
LED scanner, xerographics, and paper output and finishing. The marking engine is only accessible to the
Controller via inter-chip communication with no other access and does not store user data.
Controller
The controller manages document processing using proprietary hardware and algorithms to process
documents into high-quality electronic and/or printed reproductions. Documents may be temporarily
buffered in RAM during processing. Some models may be equipped with additional storage options such
as magnetic Hard Disk Drive (HDD), Solid State Disk (SSD), SD Card, or Flash media. For model
specific details please see Appendix A: Product Security Profiles. AltaLink® and VersaLink® products
encrypt user data and include media sanitization (overwrite) options that ensure that erased data cannot
be recovered, described further in section 3User Data Protection.
In addition to managing document processing the controller manages all network functions and services.
Details can be found in section Network Security.
The controller handles all I/O communications with connected products. The following section provides a
description of each interface. Please note that not all interfaces are supported on all models; details
about each model can be found in Appendix A: Product Security Profiles.
Controller External Interfaces
Front Panel USB (Type A) port(s)
One or more USB ports may be located on the front of the product, near the user interface. Front USB
ports may be enabled or disabled by a system administrator. The front USB port supports the following:
Walk-up users may insert a USB thumb drive to store or retrieve documents for scanning and/or
printing from a FAT formatted USB device. The controller will only allow reading/writing of a
limited set of known document types (such as DOC, PDF, PNG, JPEG, TIFF, etc.). Other file
types including binary executables are not supported.
Note that features that use the front USB ports (such as Scan To USB) can be disabled
independently or restricted using role-based access controls.
Connection of optional equipment such as NFC or CAC readers.
Firmware updates may be submitted through the front USB ports. (Note that the product must be
configured to allow local firmware updates, or the update will not be processed.

10/100/1000 MB Ethernet RJ-45 Network Connector
This is a standard RJ45 Ethernet network connector and confirms to IEEE Ethernet 802.3 standards.
Rear USB (Type B) Target port
A USB type B port located on the controller board at the rear of the product. This port supports the
following:
USB target connector used for printing
Note: This port can be disabled completely by a system administrator.
Optional Equipment
RJ-11 Analog Fax and Telephone
The analog fax module connects to the controller. The fax connection supports the Fax Modem T.30
protocol only and will not accept data or voice communication attempts. An external (EXT) is available to
connect an external handset. In this configuration, the FAX card acts as a passive relay.
Wireless Network Connector
VersaLink® products accept an optional wireless module via a proprietary port.
AltaLink® products accept an optional wireless kit that can be installed in the rear USB port.
Near Field Communications (NFC) Reader
The system supports an installable RFID reader for authentication and convenience in certain
configurations. VersaLink® products accept the RFID reader via USB on the front of the product.
AltaLink® products come standard with an RFID reader built into the front panel. This communication
cannot write or change any settings on the system. The data exchanged is not encrypted and may
include information including system network status, IP address and product location. NFC functionality
can be disabled using the embedded web server of the product. NFC functionality requires a software
plugin that can be obtained from Xerox sales and support. NFC functionality is supported via optional
touch screen user interface or optional dedicated NFC USB dongle.
Information shared over NFC includes: IPv4 Address, IPv6 Address, MAC Address, UUID (a unique
identifier on the NFC client), and Fully qualified domain name
SMART CARD –CAC/PIV
All VersaLink® products support CAC/PIV login by enabling the VersaLink® Plug-in feature and then
enabling the appropriate plug-in. Additional plug-ins can be downloaded from Xerox.com in the product
Support area online.
All VersaLink® products support SIPR network access through a plug-in. The SIPR network plug-in is
restricted only to users who have purchased the SIPR kit from Xerox. Contact your Xerox sales
representative for details.
Foreign Product Interface
This port is used to connect optional equipment to control access to the machine. A typical application is
a coin-operated product where a user must deposit money to enable the machine to print. The
information available via the Foreign Product Interface is limited to optically-isolated pulses that can be
used to count impressions marked on hardcopy sheets. No user data is transmitted to or from this
interface.

3 User Data Protection
Xerox printers and multifunction products receive, process, and may optionally store user data from
several sources including as local print, scan, fax, or copy jobs or mobile and cloud applications, etc.
Xerox products protect user data being processed by employing strong encryption. When the data is no
longer needed, the Image Overwrite (IIO) feature automatically erases and overwrites the data on
magnetic media, rendering it unrecoverable. As an additional layer of protection, an extension of IIO
called On-Demand Image Overwrite (ODIO) can be invoked to securely wipe all user data from magnetic
media.
User Data protection while within product
This section describes security controls that protect user data while it is resident within the product. For a
description of security controls that protect data in transit please refer to the following section that
discusses data in transit; also the Network Security section of this document.
Encryption
All user data being processed or stored to the product is encrypted by default. Note that encryption may
be disabled to enhance performance on AltaLink® products (though this is not recommended in secure
environments). Xerox VersLink products do not have such an option.
The algorithm used in the product is AES-256. The encryption key is automatically created at start up
and stored in the RAM. The key is deleted by a power-off, due to the physical characteristics of the RAM.
TPM Chip
Some models include a Trusted Platform Module (TPM). The TPM is compliant with ISO/IEC 11889, the
international standard for a secure cryptoprocessor, dedicated to secure cryptographic keys. The TPM is
used to securely hold the product storage encryption key. Please refer to Appendix A: Product Security
Profiles for model specific information.
Media Sanitization (Image Overwrite)
AltaLink® and VersaLink® products equipped with magnetic hard disk drives are compliant with NIST
Special Publication 800-88 Rev1: Guidelines for Media Sanitization. User data is securely erased using a
three-pass algorithm as described in the following link:
https://nvlpubs.nist.gov/nistpubs/specialpublications/nist.sp.800-88r1.pdf
Immediate Image Overwrite
When enabled, Immediate Image Overwrite (IIO) will overwrites any temporary files that were created on
the magnetic hard disk that may contain user data. The feature provides continuous automatic
overwriting of sensitive data with minimal impact to performance, robust error reporting, and logging via
the Audit Log.
On-Demand Image Overwrite
Complementing the Immediate Image Overwrite is On-Demand Overwrite (ODIO). While IIO overwrites
individual files, ODIO overwrites entire partitions. The ODIO feature can be invoked at any time and
optionally may be scheduled to run automatically.
Note: Solid State storage media such as Solid-State Disk, eMMC, SD-Card, and Flash media cannot be completely
sanitized by multi-pass overwriting methods due to the memory wear mapping that occurs. (Additionally, attempts to do
so would also greatly erode the operational lifetime of solid state media). Solid State media is therefore not
recommended for use in highly secure environments. Please refer to NIST-800-88 “Table A-8: Flash Memory-Based
Storage Product Sanitization” for technical details.

Xerox® Security Guide for Office Class Products: AltaLink® VersaLink®

User Data in transit
This section focuses on the protection of user data (print/scan/other jobs) in transit as they are submitted
to the product for processing and/or are sent from the product to other systems. Additional protections
are also discussed in the Network Security section of this document.
Inbound User Data
Print Job Submission
In addition to supporting network level encryption including IPSec and WPA Xerox products also support
encryption of print job data at the time of submission. This can be used to securely transmit print jobs
over unencrypted connections or to enhance existing network level security controls.

Public Key Encryption (PKI)
A digital certificate is a file that contains data used to verify the identity of the client or server in a network
transaction. A certificate also contains a public key used to create and verify digital signatures. To prove
identity to another product, a product presents a certificate trusted by the other product. The product can
also present a certificate signed by a trusted third party and a digital signature proving that it owns the
certificate.
A digital certificate includes the following data:
• Information about the owner of the certificate
• The certificate serial number and expiration date
• The name and digital signature of the certificate authority (CA) that issued the certificate
• A public key
• A purpose defining how the certificate and public key can be used
There are four types of certificates:
• A Product Certificate is a certificate for which the printer has a private key. The purpose specified in the
certificate allows it to be used to prove identity.
• A CA Certificate is a certificate with authority to sign other certificates.
• A Trusted Certificate is a self-signed certificate from another product that you want to trust.
• A domain controller certificate is a self-signed certificate for a domain controller in your network.
Domain controller certificates are used to verify the identity of a user when the user logs in to the product
using a Smart Card.
For protocols such as HTTPS, the printer is the server, and must prove its identity to the client Web
browser. For protocols such as 802.1X, the printer is the client, and must prove its identity to the
authentication server, typically a RADIUS server.
Device Certificates
AltaLink® and VersaLink® products support both CA signed and self-signed certificates. Product
certificates support a bit length of up to 2048 bits.
A CA signed certificate can be created by generating a Certificate Signing Request (CSR), and sending it
to a CA or a local server functioning as a CA to sign the CSR. An example of a server functioning as a
certificate authority is Windows Server 2008 running Certificate Services. When the CA returns the signed
certificate, install it on the printer.
Alternatively, a self-signed certificate may be created. When you create a Product Certificate, the product
generates a certificate, signs it, and creates a public key used in SSL/TLS encryption.

Trusted Certificates
Public certificates may be imported to the product’s certificate store for validation of trusted external
products. The following categories are supported:
• A Trusted Root CA Certificate is a certificate with authority to sign other certificates. These certificates
usually are self-signed certificates that come from another product or service that you want to trust.
• An Intermediate CA Certificate is a certificate that links a certificate to a Trusted Root CA Certificate in
certain network environments.
• Other Certificates are certificates that are installed on the printer for solution-specific uses.
An administrator can specify the minimum encryption key length required for certificates. If a user
attempts to upload a certificate that contains a key that does not meet this requirement, a message
appears. The message alerts the user that the certificate they are attempting to upload does not meet
the key length requirement.

Network Access Control
802.1x
In 802.1X authentication, when the product is connected to the LAN port of Authenticator such as the
switch as shown below, the Authentication Server authenticates the product, and the Authenticator
controls access of the LAN port according to the authentication result. The product starts authentication
processing at startup when the startup settings for 802.1X authentication are enabled.

Cisco Identity Services Engine (ISE)
Cisco ISE is an intelligent security policy enforcement platform that mitigates security risks by providing a
complete view of which users and what products are being connected across the entire network
infrastructure. It also provides control over what users can access your network and where they can go.
Cisco's ISE includes over 200 Xerox product profiles that are ready for security policy enablement. This
allows ISE to automatically detect Xerox products in your network. Xerox products are organized in Cisco
ISE under product families, such as AltaLink® and VersaLink®, enabling Cisco ISE to automatically
detect and profile new Xerox products from the day they are released. Customers who use Cisco ISE
find that including Xerox products in their security policies is simpler and requires minimal effort.
Cisco ISE Profiling Services provides dynamic detection and classification of endpoints connected to the
network. ISE collects various attributes for each network endpoint to build an endpoint database. The
classification process matches the collected attributes to prebuilt or user-defined conditions, which are
then correlated to an extensive library of product profiles. These profiles include a wide range of product
types, including tablets, smartphones, cameras, desktop operating systems (for example, Windows®,
Mac OS® X, Linux® and others), and workgroup systems such as Xerox printers and MFPs.
Once classified, endpoints can be authorized to the network and granted access based on their profile
signature. For example, guests to your network will have different level of access to printers and other
end points in your network. As an example, you and your employees can get full printer access when
accessing the network from a corporate workstation but be granted limited printer access when accessing
the network from your personal Apple® iPhone®.
Cisco ISE allows you to deploy the following controls and monitoring of Xerox products:
Automatically provision and grant network access rights to printers and MFPs to prevent
inappropriate access (including automatically tracking new printing products connecting to the
network):
oBlock non-printers from connecting on ports assigned to printers
