2.2. Controller  
2.2.1.Purpose  
The controller provides both network and direct-connect external interfaces, and enables copy, print, email, network  
scan, server fax, internet FAX, and LanFAX functionality. Network scanning, server fax, internet fax, and LanFax, are  
standard features.  
NOTE: The Copier only version includes a hard drive which is used to hold Operating System software, printing  
applications, and jam clearance videos. Job Image data is not stored on this disk.  
Image Overwrite, which is included as a standard feature, enables both Immediate and On-Demand overwrite of any  
temporary image data created on disk. The controller also incorporates an open-source web server (Apache) that  
exports a Web User Interface (WebUI) through which users can submit jobs and check job and machine status, and  
through which system administrators can remotely administer the machine.  
The controller contains the image path, which uses proprietary hardware and algorithms to process the scanned  
images into high-quality reproductions. Scanned images may be temporarily buffered in DRAM to enable electronic  
pre-collation, sometimes referred to as scan-once/print-many. When producing multiple copies of a document, the  
scanned image is processed and buffered in the DRAM in a proprietary format. Extended buffer space for very large  
documents is provided on the network disk. The buffered bitmaps are then read from DRAM and sent to the Image  
Output Terminal (IOT) for marking on hardcopy output. For long documents, the production of hardcopy may begin  
before the entire original is scanned, achieving a level of concurrency between the scan and mark operations.  
The controller operating system is Wind River Linux, kernel v. 2.6.20+. (Note: Consistent with Flaw Remediation, this  
baseline may be updated as indicated by the ‘+’ sign. Unnecessary services such as rsh, telnet and finger are disabled  
in the OS. FTP is used in client-only mode by the network scanning feature for the filing of scanned images and the  
retrieval of Scan Templates; however the controller does not contain an FTP server.  
The controller works with the Graphical User Interface (GUI) assembly to provide system configuration functions. A  
System Administrator PIN must be entered at the GUI in order to access these functions.

Additional Information: There are also a number of RAM buffers in the video path that are used for image  
manipulation (Reduce/Enlarge, etc.), and all have no data retention capability. When power is removed all data is lost.  
These buffers are typically built into the ASICs. Typical bleed down time for all volatile memory is 10 seconds.

2.8. Logical Access  
2.8.1. Network Protocols  
The supported network protocols are listed in Appendix D and are implemented to industry standard specifications  
(i.e. they are compliant to the appropriate RFC) and are well-behaved protocols. There are no ‘Xerox unique’  
additions to these protocols.  
2.8.1.1. IPSec  
The device supports IPSec tunnel mode. The print channel can be secured by establishing an IPSec association  
between a client and the device. A shared secret is used to encrypt the traffic flowing through this tunnel. SSL must  
be enabled in order to set up the shared secret.  
When an IPSec tunnel is established between a client and the machine, the tunnel will also be active for  
administration with SNMPv2 tools (HP Open View, etc.), providing security for SNMP SETs and GETS with an  
otherwise insecure protocol. SNMP Traps may not be secure if either the client or the device has just been rebooted.  
IP Filtering can be useful to prevent SNMP calls from non-IPSec clients.  
Once an IPSec channel is established between two points, it stays open until one end reboots or goes into power  
saver,. Only network clients and servers will have the ability to establish an IPSec tunnel with the machine. Thus

XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper  
device-initiated operations (like scanning) cannot assume the existence of the tunnel unless a print job (or other  
client initiated action) has been previously run since the last boot at either end of the connection.

Please note that there is no ftp port in this list. ftp is only used to export scanned images and to retrieve Scan Job  
Templates, and will open port 21 on the remote device. An ftp port is never open on the controller itself.  
2.8.2.1. Port 25, SMTP  
This unidirectional port is open only when Scan to E-mail or Internet Fax (I-Fax) is exporting images to an SMTP  
server, or when email alerts are being transmitted. SMTP messages & images are transmitted to the SMTP server  
from the device.  
2.8.2.2. Port 53, DNS  
Designating a DNS server will allow the device to resolve domain names. This can be configured via the LocalUI or  
WebUI.  
2.8.2.3. Port 68, DHCP  
This port is used only when performing DHCP, and is not open all of the time. To permanently close this port, DHCP  
must be explicitly disabled. This is done in User Tools via the Local User Interface or via the TCP/IP page in the  
Properties tab on the WebUI.

to machine information:  
The HTTP port can only access the HTTP server residing in the controller. The embedded HTTP server is Apache. The  
purpose of the HTTP server is to:  
Give users information of the status of the device;  
View the job queue within the device and delete jobs;  
Allow users to download print ready files and program Scan to File Job Templates;  
Allow remote administration of the device. Many settings that are on the Local UI are replicated in the  
device’s web pages. Users may view the properties of the device but not change them without logging into the  
machine with administrator privileges.  
The HTTP server can only host the web pages resident on the hard disk of the device. It does not and cannot act as a  
proxy server to get outside of the network the device resides on. Hence the server cannot access any networks (or  
web servers) outside of the customer firewall.  
When the device is configured with an IP address, it is as secure as any device inside the firewall. The web pages are  
accessible only to authorized users of the network inside the firewall.  
This service (and port) may be disabled in User Tools via the Local User Interface or via the TCP/IP page in the  
Properties tab on the WebU. Please note that when this is disabled, IPP Port 631 is also disabled.  
HTTP may be secured by enabling Secure Sockets Layer.  
2.8.2.4.1.  
Proxy Server  
The device can be configured to communicate through a proxy server. Features that can make use of a proxy server  
include the Automatic Meter Read feature, scanning to a remote repository, or retrieving scan templates from a  
remote template pool.

2.8.2.5. Port 88, Kerberos  
This port is only open when the device is communicating with the Kerberos server to authenticate a user, and is only  
used only to authenticate users in conjunction with the Network Scanning feature. To disable this port,  
authentication must be disabled, and this is accomplished via the Local User Interface.  
This version of software has Kerberos 5.1.1 with DES (Data Encryption Standard) and 64-bit encryption. The Kerberos  
code is limited to user authentication, and is used to authenticate a user with a given Kerberos server as a valid user  
on the network. Please note that the Kerberos server (a 3rd party device) needs to be set up for each user. Once the  
user is authenticated, the Kerberos software has completed its task. This code will not and cannot be used to encrypt  
or decrypt documents or other information.  
This feature is based on the Kerberos program from the Massachusetts Institute of Technology (MIT). The Kerberos  
network authentication protocol is publicly available on the Internet as freeware at  
software. However, there are a few deviations our version of Kerberos takes from the standard Kerberos  
implementation from MIT. These deviations are:  
1) The device does not keep a user’s initial authentication and key after the user has been authenticated. In a  
standard Kerberos implementation, once a user is authenticated, the device holds onto the authentication for a  
programmed timeout (the usual default is 12 hours) or until the user removes it (prior to the timeout period). In  
the Xerox implementation, all traces of authentication of the user are removed once they have been  
authenticated to the device. The user can send any number of jobs until the user logs off the system, either  
manually or through system timeout.  
2) The device ignores clock skew errors. In a standard implementation of Kerberos, authentication tests will fail if a  
device clock is 5 minutes (or more) different from the Kerberos server. The reason for this is that given enough  
time, someone could reverse engineer the authentication and gain access to the network. With the 5-minute  
timeout, the person has just 5 minutes to reverse engineer the authentication and the key before it becomes  
invalid. It was determined during the implementation of Kerberos for our device that it would be too difficult for  
the user/SA to keep the device clock in sync with the Kerberos server, so the Xerox instantiation of Kerberos has  
the clock skew check removed. The disadvantage is that this gives malicious users unlimited time to reverse  
engineer the user’s key. However, since this key is only valid to access the Network Scanning features on a  
device, possession of this key is of little use for nefarious purposes.  
3) The device ignores much of the information provided by Kerberos for authenticating. For the most part, the  
device only pays attention to information that indicates whether authentication has passed. Other information  
that the server may return (e.g. what services the user is authenticated for) is ignored or disabled in the Xerox  
implementation. This is not an issue since the only service a user is being authenticated for is access to an e-  
mail directory. No other network services are accessible from the Local UI.  
Xerox has received an opinion from its legal counsel that the device software, including the implementation of a  
Kerberos encryption protocol in its network authentication feature, is not subject to encryption restrictions based on  
Export Administration Regulations of the United States Bureau of Export Administration (BXA). This means that it  
can be exported from the United States to most destinations and purchasers without the need for previous approval  
from or notification to BXA. At the time of the opinion, restricted destinations and entities included terrorist-  
supporting states (Cuba, Iran, Libya, North Korea, Sudan and Syria), their nationals, and other sanctioned entities  
such as persons listed on the Denied Parties List. Xerox provides this information for the convenience of its customers  
and not as legal advice. Customers are encouraged to consult with legal counsel to assure their own compliance with  
applicable export laws.  
2.8.2.6. Port 110, POP-3 Client  
This unidirectional port is used when receiving an Internet Fax (I-Fax) or E-Mail. These jobs may only be printed, and  
the port is only open if I-Fax is enabled and while receiving the job. It is not configurable.

2.8.2.7. Ports 137, 138, 139, NETBIOS  
For print jobs, these ports support the submission of files for printing as well as support Network Authentication  
through SMB. Port 137 is the standard NetBIOS Name Service port, which is used primarily for WINS. Port 138  
supports the CIFS browsing protocol. Port 139 is the standard NetBIOS Session port, which is used for printing. Ports  
137, 138 and 139 may be configured in the Properties tab of the device’s web page.  
For Network Scanning features, ports 138 and 139 are used for both outbound (i.e. exporting scanned images and  
associated data) and inbound functionality (i.e. retrieving Scan Templates). In both instances, these ports are only  
open when the files are being stored to the server or templates are being retrieved from the Template Pool. For these  
features, SMB protocol is used.  
2.8.2.8. Ports 161, 162, SNMP  
These ports support the SNMPv1, SNMPv2c, and SNMPv3 protocols. Please note that SNMP v1 does not have any  
password or community string control. SNMPv2 relies on a community string to keep unwanted people from  
changing values or browsing parts of the MIB. This community string is transmitted on the network in clear text so  
anyone sniffing the network can see the password. Xerox strongly recommends that the customer change the  
community string upon product installation. SNMP is configurable, and may be explicitly enabled or disabled in the  
Properties tab of the device’s web pages.  
SNMP traffic may be secured if an IPSec tunnel has been established between the agent (the device) and the  
manager (i.e. the user’s PC).  
The device supports SNMPv3, which is an encrypted version of the SNMP protocol that uses a shared secret. Secure  
Sockets Layer must be enabled before configuring the shared secret needed for SNMPv3.  
2.8.2.9. Port 389, LDAP  
This is the standard LDAP port used for address book queries in the Scan to Email feature.  
2.8.2.10. Port 396, Netware  
This configurable port is used when Novell Netware is enabled to run over IP.  
2.8.2.11. Port 427, SLP  
When activated, this port is used for service discovery and advertisement. The device will advertise itself as a printer  
and also listen for SLP queries using this port. It is not configurable. This port is explicitly enabled / disabled in the  
Properties tab of the device’s web pages.  
2.8.2.12. Port 443, SSL  
This is the default port for Secure Sockets Layer communication. This port can be configured via the device’s web  
pages. SSL must be enabled before setting up either SNMPv3 or IPSec or before retrieving the audit log (see Sec.  
4.1). SSL must also be enabled in order to use any of the Web Services (Scan Template Management, Automatic  
Meter Reads, or Network Scanning Validation Service).  
SSL should be enabled so that the device can be securely administered from the web UI. When scanning, SSL can be  
used to secure the filing channel to a remote repository.  
SSL uses X.509 certificates to establish trust between two ends of a communication channel. When storing scanned  
images to a remote repository using an https: connection, the device must verify the certificate provided by the  
remote repository. A Trusted Certificate Authority certificate should be uploaded to the device in this case.  
To securely administer the device, the user’s browser must be able to verify the certificate supplied by the device. A  
certificate signed by a well-known Certificate Authority (CA) can be downloaded to the device, or the device can  
generate a self-signed certificate. In the first instance, the device creates a Certificate Signing Request (CSR) that  
can be downloaded and forwarded to the well-known CA for signing. The signed device certificate is then uploaded  
to the device. Alternatively, the device will generate a self-signed certificate. In this case, the generic Xerox root CA  
certificate must be downloaded from the device and installed in the certificate store of the user’s browser.  
The device supports only server authentication.

2.8.2.13. Port 515, LPR  
This is the standard LPR printing port, which only supports IP printing. It is a configurable port, and may be explicitly  
enabled or disabled in the Properties tab of the device’s web pages.  
2.8.2.14. Port 631, IPP  
This port supports the Internet Printing Protocol. It is not configurable. This is disabled when the http server is  
disabled.  
2.8.2.15. Port 1900, SSDP  
This port behaves similarly to the SLP port. When activated, this port is used for service discovery and advertisement.  
The device will advertise itself as a printer and also listen for SSDP queries using this port. It is not configurable. This  
port is explicitly enabled / disabled in the Properties tab of the device’s web pages.  
2.8.2.16. Port 3003, http/SNMP reply  
This port is used when the http server requests device information. The user displays the Web User Interface  
(WebUI) and goes to a page where the http server must query the device for settings (e.g. Novell network settings).  
The http server queries the machine via an internal SNMP request (hence this port can only open when the http  
server is active). The machine replies back to the http server via this port. It sends the reply to the loopback address  
(127.0.0.0), which is internally routed to the http server. This reply is never transmitted on the network. Only SNMP  
replies are accepted by this port, and this port is active when the http server is active (i.e. if the http server is disabled,  
this port will be closed). If someone attempted to send an SNMP reply to this port via the network, the reply would  
have to contain the correct sequence number, which is highly unlikely, since the sequence numbers are internal to the  
machine.  
2.8.2.17. Port 9100, raw IP  
This allows downloading a PDL file directly to the interpreter. This port has limited bi-directionality (via PJL back  
channel) and allows printing only. This is a configurable port, and may be disabled in the Properties tab of the  
device’s web pages.  
2.8.3. IP Filtering  
The devices contain a static host-based firewall that provides the ability to prevent unauthorized network access  
based on IP address and/or port number. Filtering rules can be set by the SA using the WebUI. An authorized SA can  
create rules to (Accept / Reject / Drop) for ALL or a range of IP addresses. In addition to specifying IP addresses to  
filter, an authorized SA can enable/disable all traffic over a specified transport layer port.

3. System Access  
3.1. Authentication Model  
The authentication model allows for both local and network authentication and authorization. In the  
local and network cases, authentication and authorization take place as separate processes: a user must  
be authenticated before being authorized to use the services of the device.  
If the device is set for local authentication, user account information will be kept in a local accounts  
database (see the discussion in Chapter 4 of Xerox Standard Accounting) and the authentication process  
will take place locally. The system administrator can assign authorization privileges on a per user basis.  
User access to services will be provided based on the privileges set for each user in the local accounts  
database. .  
When the device is set for network authentication, the user’s network credentials will be used to  
authenticate the user at the network domain controller.  
Users can be authorized on an individual basis to access one or any combination of the following services:  
Copy, Fax, Server Fax, Reprint Saved Jobs, Email, Internet Fax, Workflow Scanning Server.  
Also users can be authorized to access one or any combination of the following machine pathways:  
Services, Job Status, or Machine Status.  
Assignment of users to the System Administrator role or the Accounting Administrator is managed by  
groups set up at the LDAP or Active Directory server. Any user listed in the System Administrator group  
will be granted sys admin privileges at the device. Likewise any user listed in the Accounting  
Administrator group will be granted the privileges for that role. Use of network credentials for system  
administrator login provides more security than the legacy model based on a sys admin PIN, allowing for  
better tracking of sys admin logins by individual users.  
Figure 3-1 provides a schematic view of the authentication and authorization subsystem. Use of the local  
accounts database or the network can be set independently for both authentication and authorization,  
meaning that it is possible to enable network authentication and local authorization, or vice versa.  
Usually the device will be set for both authentication and authorization to take place against the same  
database, either local or network.

3.2. Login and Authentication Methods  
There are a number of methods for different types of users to be authenticated. In addition, the  
connected versions of the product also log into remote servers. A description of these behaviors follows.  
3.2.1. System Administrator Login [All product configurations]  
Users must authenticate themselves to the device. To access the User Tools via the Local UI, a numerical  
PIN is required. The customer can set the PIN to anywhere from 3 to 31digits in length. This PIN is  
stored in the controller NVM and is inaccessible to the user. Xerox strongly recommends that this PIN be  
changed from its default value immediately upon product installation. The PIN should be set to a  
minimum of 8 characters in length and changed at least once per month. Longer PINs can be changed  
less frequently; a 9-digit PIN would be good for a year. The same PIN is used to access the  
Administration screens in the Web UI.  
3.2.2. User authentication  
Users may authenticate to the device using Kerberos, LDAP, SMB Domain, or NDS authentication  
protocols. Once the user is authenticated to the device, the user may proceed to use the Network  
Scanning features listed above.  
The WebUI allows an SA to set up a default authentication domain and as many as 8 additional  
alternate authentication domains. The device will attempt to authenticate the user at each domain  
server in turn until authentication is successful, or the list is exhausted.  
3.2.2.1. Kerberos Authentication (Solaris or Windows 2000/Windows 2003)  
This is an option that must be enabled on the device, and is used in conjunction with all Network  
Scanning features (Scan to File, Scan to E-mail, internet fax, and Scan to Fax Server). The authentication  
steps are:  
1) A User enters a user name and password at the device in the Local UI. The device sends an  
authentication request to the Kerberos Server.  
2) The Kerberos Server responds with the encrypted credentials of the user attempting to sign on.  
3) The device attempts to decrypt the credentials using the entered password. The user is  
authenticated if the credentials can be decrypted.  
4) The device then logs onto and queries the LDAP server trying to match an email address against the  
user’s Login Name. The user’s email address will be retrieved if the personalization option has been  
selected on the Authentication Configuration page.  
5) If the LDAP Query is successful, the user’s email address is placed in the From: field. Otherwise, the  
user’s login name along with the system domain is used in the From: field.  
6) The user may then add recipient addresses by accessing the Address Book on the LDAP server. Please  
see the User Manual for details. Each addition is a separate session to the LDAP server.  
3.2.2.2. SMB Authentication (Windows NT 4 or Windows 2000/Windows 2003)  
This is also an option that may be enabled on the device, and is used in conjunction with all Network  
Scanning features (Scan to File, Scan to E-mail, internet fax, and Scan to Fax Server). The authentication  
steps vary somewhat, depending on the network configuration. Listed below are 3 network  
configurations and the authentication steps.  
Basic Network Configuration: Device and Domain Controller are on the same Subnet  
Authentication Steps:  
1) The device broadcasts an authentication request that is answered by the Domain Controller.  
Ver. 2.00, March 2011  
Page 24 of 50  
XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper  
2) The Domain Controller responds back to the device whether or not the user was successfully  
authenticated.  
If (2) is successful, steps 3 – 5 proceed as described in steps 4 – 6 of the Kerberos section.  
Device and Domain Controller are on different Subnets, SA defines IP Address of Domain Controller  
Authentication Steps:  
1) The device sends an authentication request directly to the Domain Controller through the  
router using the IP address of the Domain Controller.  
2) The Domain Controller responds back to the device through the router whether or not the user  
was successfully authenticated.  
If (2) is successful, steps 3 – 5 proceed as described in 4 - 6 of Kerberos section.

3) The device sends an authentication request directly to the Domain Controller through the  
router using the IP address of the Domain Controller.  
4) The Domain Controller responds back to the device through the router whether or not the user  
was successfully authenticated.  
If (4) is successful, steps 5 – 7 proceed as described in steps 4 - 6 of the Kerberos section.  
3.2.2.3. DDNS  
The implementation in the device does not support any security extensions.  
3.3. System Accounts  
3.3.1. Printing [Multifunction models only]  
The device may be set up to connect to a print queue maintained on a remote print server. The login  
name and password are sent to the print server in clear text. IPSec should be used to secure this channel.  
3.3.2. Network Scanning [Multifunction models only]  
Network Scanning may require the device to log into a server. The instances where the device logs into a  
server are detailed in the following table. Users may also need to authenticate for scanning. This  
authentication is detailed in subsequent sections.  
3.3.2.1. Device log on  
Scanning feature  
Scan to File, Public Template  
Device behavior  
The device logs in to the scan repository as set up by the SA in User  
Tools.  
Scan to E-mail, I-Fax  
The device logs into an SMTP Server as set up by the SA in User  
Tools. It will only log into the Server when a user attempts to use  
the scan-to-email feature. At the time the LDAP server must be  
accessed, the device will log into the LDAP server.  
The device uses simple authentication on the SMTP server. A network  
username and password must be assigned to the device. The device  
logs in as a normal user, with read only privileges. User credentials are  
not used for this authentication step, and are never transmitted over the  
network.  
Scan to Fax Server  
The device logs in to the Fax Server as set up by the SA in User Tools on  
the Local UI or from the Properties tab on the WebUI.  
Please note that when the device logs into any server the device username and password are sent over  
the network in clear text unless SSL has been enabled or IPSec has been configured to encrypt the traffic.  
3.3.2.2. Scan Template Management  
This is a web service that allows the SA to manage templates stored in a remote template pool. The  
connection to the remote pool can be secured with SSL.

3.4. Diagnostics  
3.4.1. Service [All product configurations]  
To access onboard diagnostics from the local user interface, Xerox service representatives must enter a  
unique 4-digit password. This PIN is the same for all product configurations and cannot be changed.  
For additional security, a Xerox authorized service representative can enable a “secure diagnostics” mode.  
In this mode, the service representative must enter two PINs to access onboard diagnostics. When  
enabling the secure diagnostics mode for the first time, the service representative should change the PIN  
to something known only to him or his local team. On subsequent logins, the secure diagnostics PIN must  
be entered followed by the standard diagnostics PIN in order to gain access to the diagnostics menu.  
3.4.2. Alternate Boot via Serial Port  
Alternate Boot (Alt-boot) is a means for the Portable Service Workstation (PSW) to directly connect to the  
controller. The primary purpose of Alternate Boot is to provide the capability to boot the controller in  
case of hard disk failure, to perform system diagnostics, and load controller software, independent of  
other sub-systems.  
To enter this mode a user must strike any key on the PSW within 10 seconds of power on. If the 10  
seconds times out, then the normal boot sequence occurs and the serial port acts as a typical tty (see  
next section). However, if this mode is entered, a Xerox unique serial protocol is used to communicate to  
the alt-boot code. All commands are DOS-type menu driven (i.e. type in a number to start a command).  
If a PSW is connected, the application on the PSW cannot be accessed without logging on with a  
password (see next section).  
If the PSW is used and is successfully logged on, then the Ethernet port is used to download executable  
files. The serial port is used for commands and status. Again, please refer to the PSW section for details.  
3.4.3. tty Mode  
When the controller has completed booting a login line will be displayed. This mode is a typical tty  
window, and is password protected. This password changes with each major software release. The  
password is stored on the controller hard disk in an encrypted format similarly to how UNIX encrypts and  
stores passwords. Through this port a user can gain information and access to any files or information  
stored in the controller DRAM or controller hard disk. However, this mode is only used by a CSE if directed  
by a Field Engineer when all other diagnostics fail to solve a problem. The written repair procedures that  
direct the CSE never employ this mode.  
3.4.4. Diagnostics via Portable Service Workstation (PSW) Port  
When connected to the PSW Port, the PSW provides an extensive suite of diagnostic functions for use by  
the Xerox Customer Service Engineer (CSE). The over-the-wire protocol is Xerox proprietary. This port  
cannot process any other protocol except this proprietary protocol used for machine diagnosis. Also, the  
PSW must have an application loaded to connect to and communicate with the device.  
Customer documents or files cannot be accessed during a diagnostic session, nor are network servers  
accessible through this port.

XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper  
3.4.4.1. Access  
The Xerox Service Technician must be authenticated twice:  
1. The first password, called the PSW Lock Facility, is obtained by calling a Xerox service location and  
providing the CSE employee number and the serial number of the PSW. The password is then given to  
the Xerox Service Technician, and is valid for 90 days. When the password expires, the Xerox Service  
Technician must call in again. This password is unique to the client application running on that particular  
PSW, and is required to log onto the PSW prior to initiating communications with the machine.  
2. Once the application is running, the PSW supplies the second password (different from the first) to  
authenticate the session to the device. This embedded password is automatically passed from the  
application to the machine, and is never seen by anyone. It is hardcoded in the software of the Marking  
Engine and the PSW application, and is common to all products. It is not encrypted. Many of the  
diagnostic routines will require this password in order to function.  
3.4.4.2. Communication Protocol  
The communication process uses a Xerox proprietary protocol. Each packet passing back and forth will  
have a unique identifier (session key) with it for authentication and tracking purposes. All protocols are  
API based – very little information is directly transferred. For example, in order to run any given  
diagnostic test, the ‘Start Test XXX’ command is sent to the Marking Engine. The Marking Engine runs  
the test and responds with a “Test XXX passed (or failed)’ reply. This is illustrated in the following  
diagram:  
Network  
Network Controller  
Marking Engine  
Marking Engine information may be  
retrieved; no image data may be accessed  
PSW (Laptop computer)  
3.4.4.3. Network Diagnostics executed from the PSW  
The PSW allows the technician to execute certain Network diagnostic tests by connecting directly to the  
serial port on the controller. These tests are executed with the device disconnected from the customer’s  
LAN.  
The tests that are available are echo tests for the various protocols (e.g. IP, IPX), where the controller  
sends a dummy message to itself to test the transmit and receive capabilities of its own connectivity  
stacks. Each protocol is tested individually and each test must be invoked separately. The diagnostic  
sequence is as follows:  
1) After the PSW and Marking Engine have established a connection, the PSW must send the expected  
synchronization message to the machine.  
2) The Marking Engine will respond with an acknowledge message containing its serial number.  
Ver. 2.00, March 2011  
Page 28 of 50  
XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper  
3) The PSW will send a request for Diagnostic service and a password.  
4) Assuming the password is authentic, the Marking Engine will either execute a Marking Engine diagnostic, or  
else forward the diagnostic request to the controller. If this is a network diagnostic, the controller will  
execute the diagnostic and report results back to the Marking Engine.  
5) The Marking Engine will report diagnostic results back to the PSW.  
3.4.4.4. Accessible Data  
The only files that are accessible are various log files (fault log, internal event log, complete job log,  
configuration log and a debug log). The customer’s network is accessible for diagnostic purposes only.  
However, there is one diagnostic routine (Get Network Connectivity Data), where the device will collect  
data about the network it is on and transmit the data. The CSE is expected to seek permission from the  
customer before connecting the device to the LAN and performing this diagnostic.  
The Novell test will only collect information for devices on the local network. It will not provide  
information for any devices across a router. The following data will be stored on the controller:  
Frame Type (local network devices only)  
Server Name  
Server internal network number

3.4.5. Summary  
As stated above, accessibility of customer documents, files or network resources is impossible via the  
PSW. In the extremely unlikely event that someone did spoof the Xerox proprietary protocols, only  
diagnostic activities can be executed.

4. Security Aspects of  
Selected Features  
4.1. Audit Log  
The device maintains a security audit log. Recording of security audit log data can be enabled or disabled  
by the SA. The audit log is implemented as a circular log containing a maximum of 15000 event entries,  
meaning that once the maximum number of entries is reached, the log will begin overwriting the earliest  
entry. Only an SA will be authorized to download the log from the device. The log may only be exported  
over an https: connection, so SSL must be set up before retrieving the log. The log is exported in MS-Excel  
comma-separated file format. The log does not clear when it is disabled, and will persist through power  
cycles.  
The following table lists the events that are recorded in the log:

4.2. Xerox Standard Accounting  
Xerox Standard Accounting (XSA), intended primarily for use as an accounting service, can be used as an  
internal authorization service. XSA tracks copy, scan (including filing and email), print and fax usage by  
individual user1. The system administrator can enable/disable the feature via the LUI or Web UI, add or  
delete users, and set usage limits by service for each user. If XSA is enabled, a walk-up user must enter a  
valid XSA ID before being allowed access to the device. The device will confirm that the entered XSA ID  
matches an authorized user, and that the usage limits for the selected service have not been exceeded. In  
this sense, XSA acts as an authorization service. The system administrator can limit access to device  
services by setting the usage limits on specific services to zero for users that should not have rights to use  
the feature. After each job is performed, the user’s balance is updated by the number of impressions or  
scans performed. Services become unavailable to the user when the usage limits are exceeded.  
When XSA is enabled in the print driver or on the Web UI, before a print job is submitted, an XSA ID must  
also be entered. The ID is sent to the controller for validation. If the submitted ID is valid, the job will print,  
and the user’s balance will be updated by the number of impressions performed. If the submitted ID is  
invalid, the job is deleted and an error sheet is printed in its place.  
1 On color machines XSA can track color copy or color print usage.  
Ver. 2.00, March 2011  
Page 39 of 50  
XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper  
On demand, the SA will be able to download a report that shows activity for all of the users. The SA can  
add, modify or remove users and their allocations at any point.  
An end user will be able to review their balances by entering a User ID at the LUI or web UI.  
4.3. Automatic Meter Reads  
Automatic Meter Reads (AMR) is a service that allows devices to electronically report meter readings back  
to Xerox. The Systems Administrator sets up the attributes for the AMR service via the web UI, including  
registering the device with the Xerox AMR server. Once enabled, the device will poll the Xerox AMR server  
daily over the network. The server will check whether it is time in the monthly billing cycle to update the  
meter readings. If so, the server will request reads from the device, and the device will then respond by  
sending the meter reads back to the server.  
This communication process means that the device initiates all communication between it and Xerox. Only  
device ID and meter read information is transferred. The information is sent in clear text.  
The device can be set to communicate via a proxy server on the customer’s network. The proxy server  
address is set up using the WebUI.  
4.4. Encrypted Partitions  
When enabled by the customer, the controller disk is encrypted using the AES algorithm with a 128-bit key.  
256-bit encryption is available via SPAR – please contact Xerox Customer Support and request SPAR 85669.  
The key is generated dynamically on each boot, and is kept only in volatile memory. Encryption is installed  
but must be enabled by the customer.  
4.5. Image Overwrite  
The Image Overwrite Security feature provides both Immediate Image Overwrite (IIO) and On-Demand  
Image Overwrite (ODIO) functions. Immediately before a job is considered complete, IIO will overwrite any  
temporary files associated with print, network scan, internet fax, network fax, or e-mail jobs that had been  
created on the controller Hard Disk. The ODIO feature can be executed at any time by the SA and will  
overwrite the entire document image partitions of the controller Hard disk. ODIO may also be scheduled to  
run at regular times. A standard ODIO will overwrite all image data from memory and disks except for Jobs  
and Folders stored in the Reprint Saved Jobs feature; Jobs stored in the Scan to Mailbox feature (if  
installed); Fax Dial Directories (if fax card is installed); and Fax Mailbox contents (if fax card is installed). A  
full ODIO will overwrite all image data from memory and disks as well as the items excluded from a  
standard ODIO.

XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper  
4.5.1. Algorithm  
The overwrite mechanism for both IIO and ODIO conforms to the U.S. Department of Defense Directive  
5200.28-M (Section 7, Part 2, paragraph 7-2022.  
The algorithm for the Image Overwrite feature is:  
Step 1: Pattern #1 is written to the sectors containing temporary files (IIO) or to the entire spooling  
area of the disks (ODIO). (hex value 0x35 (ASCII “5”)).  
Step 2: Pattern #2 is written to the sectors containing temporary files (IIO) or to the entire spooling  
area of the disks (ODIO). (hex value 0xCA (ASCII compliment of 5)).  
Step 3: Pattern #3 is written to the sectors containing temporary files (IIO) or to the entire spooling  
area of the disks (ODIO). (hex value 0x97 (ASCII “ú”)).  
Step 4: 10% of the overwritten area is sampled to ensure Pattern #3 was properly written. The 10%  
sampling is accomplished by sampling a random 10% of the overwritten area.  
4.5.2. User Behavior  
IIO can be enabled at the local UI only. Once enabled, IIO is invoked automatically immediately prior to the  
completion of a print, network scan, internet fax, network fax, or e-mail job. If IIO completes successfully,  
status is displayed in the Job Queue. However, if IIO fails, a popup will appear on the Local UI  
recommending that the user run ODIO, and a failure sheet will be printed.  
ODIO may be invoked either from the Local UI in Tools Pathway or from the CentreWare Internet Services  
Web UI. Network functions will be delayed until the overwrite is completed. Copying is unavailable while  
the overwrite itself is underway, but copies may be made while the controller is booting.  
Upon completion and verification of the ODIO process, a confirmation sheet is printed which indicates the  
status of the overwrite. The completion status can be successful, failed, cancelled, or timed-out.  
Please note that invocation of ODIO will cause currently processing print jobs to be aborted. However, scan  
jobs will not be aborted and so ODIO might fail. The user should insure that all scan jobs have been  
completed before invoking ODIO.  
Please refer to the customer documentation for a description on how failures are logged.  
4.5.3. Overwrite Timing  
The ODIO overwrite time is dependent on the type of hard disk in the product. The overwrite and reset  
average time is 10 minutes, but longer times are possible.  
IIO is performed as a background operation, with no user-perceivable reduction in copy, print or scan  
performance.

6.2. Appendix B – Supported MIB  
Objects  
NOTES :  
(1) The number of objects shown per MIB group represents the number of objects defined by the IETF  
standard for that MIB group. It does not represent the instantiation of the MIB group which may  
contain many more objects.  
(2) Some MIB objects defined within Input and Output groups of the Printer MIB (RFC 1759) have a  
MAX-ACCESS of RW. However, the Printer MIBv2 defines a MIB-ACCESS of RO for these MIB objects  
within the Input and Output groups and all machines assessed support RO access. Therefore, RO  
access to these MIB objects is considered IETF compliant.  
(3) It is assumed that mandatory IETF string-related MIB objects shall contain meaningful data; not  
blank strings  
(4) The "(C)" notation indicates that the previously stated item is a true caveat condition. The "(I)"  
notation indicates that the previous stated item should be regarded as information only.  
(5) MIB objects that CANNOT be populated with meaningful data (e.g. a machine may not have paper  
level sensors, hence, can only support "0" or "-3 for more than 1 sheet" for prtInputCurrentLevel) will  
be considered a caveat, denoted as "(C)".  
(6) The Printer MIB requires a few groups from RFC 1213 and RFC 1514 to be supported. Therefore, this  
assessment will indicate that these groups are "supported" as long as the basic MIB structures have  
been implemented.  
Support Definitions  
Term  
Definition  
"supported"  
all MIB objects exists and are populated w/ meaningful data that is consistent w/ the  
hardware installed within the machine.  
"supported w/ caveats"  
all MIB objects exists, however, 2 major bugs or less may exists w/ some of the objects that  
were not fixed  
MIB objects do not exist/implementation was not planned  
"not supported"  
"not fully supported"  
MIB objects exists, HOWEVER, are NOT populated w/ meaningful data OR provide only default  
values OR contain 3 or more major bugs  
"optional, *"  
optional group that is NOT required by the RFC, however, an implementation may exist; some  
MIB objects may not be populated w/ meaningful data
