SECURITYTARGETINTRODUCTIONThis Chapter presents Security Target (ST) identification information andan overview of the ST. An ST contains the information technology (IT)security requirements of an identified Target of Evaluation (TOE) andspecifies the functional and assurance security measures offered by thatTOE to meet stated requirements. An ST principally defines:a) A security problem expressed as a set of assumptions about thesecurity aspects of the environment, a list of threats that theproduct is intended to counter, and any known rules with which theproduct must comply (Chapter 3, TOE Security Environment).b) A set of security objectives and a set of security requirements toaddress the security problem (Chapters 4 and 5, SecurityObjectives and IT Security Requirements, respectively).c) The IT security functions provided by the TOE that meet the set ofrequirements (Chapter 6, TOE Summary Specification).The structure and content of this ST comply with the requirementsspecified in the Common Criteria (CC), Part 1 v3.1R1, Annex A, and Part3 v3.1R2, Chapter 11.1.1. ST and TOE IdentificationThis section provides information needed to identify and control this STand its associated TOE.

TOE Overview1.2.1. Usage and Major Security FeaturesThe product is a multi-function device (MFD) that copies and prints, withscan-to-email (scanned files are emailed to the user), network scan(including “scan to mailbox” where scanned files are routed to a directory),and FAX options. A standard component of the TOE is the ImageOverwrite Security package. This function forces any temporary imagefiles created during a print, network scan, scan to email, or LanFax job tobe overwritten when those files are no longer needed.The optional Xerox Embedded Fax accessory, when purchased andinstalled, provides local analog fax capability over PSTN connections.Table 1: Models and capabilities(X – included in all configurations; O – product options ordered separately)11Print Copy Network Scan Embedded Fax Scan 2 email Print SpeedUp to 32 ppmWorkCentre 5632xxoooUp to 38 ppmWorkCentre 5638xxoooUp to 45 ppmWorkCentre 5645xxoooUp to 55 ppmWorkCentre 5655xxoooUp to 65 ppmWorkCentre 5665xxoooUp to 75 ppmWorkCentre 5675xxoooUp to 87 ppmWorkCentre 5687xxooo1Copy and embedded FAX jobs are not spooled to the HDD.An optional Finisher, which is not part of the TOE, provides “after print”services such as document collation and stapling.

These models are referred to asSingle Board Controller (SBC) and Multi Board Controller (MBC). Bothmodels share a common set of security features. The MBC modelcontrollers however implement additional features not present in the SBCmodels.The MFD stores temporary image data created during a print, networkscan or scan to email, and LanFAX job on an internal hard disk drive(HDD). This temporary image data consists of the original data submittedand additional files created during a job. All partitions of the HDD used forspooling temporary files are encrypted. The encryption key is createddynamically on each power-up.Copy jobs are not written to the hard drive and need not to be overwritten.Copy/Print, Store and Reprint jobs are written to the hard drive so thatthey may be reprinted at a later time; therefore, they will be overwrittenwhen a full on-demand image overwrite is performed. Embedded FAXjobs are written to flash memory and are overwritten at the completion ofeach job, or on demand of the MFD system administrator.The TOE provides an Image Overwrite function to enhance the security ofthe MFD. The Image Overwrite function overwrites temporary documentimage data as described in DoD Standard 5200.28-M at the completion ofeach print, network scan, scan to email, or LanFAX job, once the MFD isturned back on after a power failure or on demand of the MFD systemadministrator.The optional Xerox Embedded Fax accessory provides local analog FAXcapability over Public Switched Telephone Network (PSTN) connections9 Copyright 2009 Xerox Corporation, All rights reserved
Xerox WorkCentre 5632/5638/5645/5655/5665/5675/5687Multifunction Systems Security Targetand also enables LanFax jobs, if purchased by the consumer. A separatenon-volatile memory resource is dedicated to embedded fax, and theimage files written to this memory are zeroized at the completion of a faxjob.User image files associated with the Copy/Print, Store and Reprint featuremay be stored long term for later reprinting. When a job is selected forreprint, the stored job is resubmitted to the system. Temporary filescreated during processing are overwritten at the completion of the jobusing the 5200.28-M algorithm. The stored jobs are not overwritten untilthe jobs are deleted by the user, or when the System Administratorexecutes a full on-demand image overwrite.Xerox’s optional Network Scanning Accessory may be purchased andadded to the TOE configuration. This accessory allows documents to bescanned at the device with the resulting image being stored on a remoteserver/repository. The connection between the device and the remoteserver is secured when the TOE’s SSL support is enabled; the transfer ofthe data is through an HTTPS connection. The TOE supports networkscanning using FTP, HTTPS (SSL), SMTP over IPv4 and IPv6 withsupport for utilizing LDAP over IPv4 and IPv6. The cryptography used toprotect this connection has been scoped out of the evaluation.All models of the TOE support both auditing and network security. Thesystem administrator can enable and configure the network securitysupport. The network security support is based on SSL. When SSLsupport is enabled on the device, the following network security featurescan be enabled/configured: HTTPS support over both IPv4 and IPv6 (forboth the device’s Web UI and secure network scan data transfer); systemadministrator download of the device’s audit log; IPSec support for IPP, lprand port 9100 print jobs over IPv4 or IPv6; and specification of IPv4 andIPv6 filtering rules. Scan-to-email and FAX data are not protected fromsniffing by the IPSec or SSL support. The transmission of LanFax dataover the Ethernet connection is protected by IPSec, but the transmissionover the PSTN is not. Note that for the MFD configuration, IPSec can onlybe activated if SSL has been enabled and an SSL-based certificate (either“self-signed” or generated by an external Certificate Authority) has beenloaded into the TOE via the Web UI. Once this has occurred, SSL couldbe disabled. Except for the cryptography used to protect the audit logs(SSL v3.1), the cryptography used for network security has been scopedout of the evaluation.The TOE provides for user identification and authorization based on eitherlocal or remote ACL’s as configured by the system administrator.The TOE can integrate with an IPv4 or IPv6 network with native supportfor dhcp/dhcpv6.In addition to the features of the SBC architecture the MBC based modelssupport the Common Access Card (CAC) standard for authentication.10 Copyright 2009 Xerox Corporation, All rights reserved

TOE TypeThe TOE is a multi-function device (MFD) that provides copy, print,document scanning and optional FAX services.1.2.3. Required Non-TOE Hardware, Software andFirmwareThe TOE does not require any additional hardware, software or firmwarein order to function as a multi-function device, however, the networksecurity features are only useful in environments where the TOE isconnected to a network. TSF NET ID is only available when one of thefollowing remote authentication services are present on the network thatthe TOE is connected to: LDAP, NDS, Kerberos, or SMB.1.3. TOE DescriptionThis section provides context for the TOE evaluation by identifying thelogical and physical scope of the TOE, as well as its evaluatedconfiguration.1.3.1. Physical Scope of the TOEThe TOE is a Multi-Function Device (Xerox WorkCentre model 5632,5638, 5645, 5655, 5665, 5675, or 5687) that consists of a printer, copier,scanner, FAX (when purchased by the consumer), and email as well as allAdministrator and User guidance (all dated December 16th, 2008). Thedifference between the seven models is their printing speed. A DuplexAutomatic Document Handler is available on all models; the 5632 isavailable in a platen-only configuration. The hardware included in theTOE is shown in Figure 1. This figure also shows an optional Finisherconnected to the TOE at the right side of the picture and an optional PaperFeeder at the left side of the picture, neither of which are part of the TOE.The optional FAX card is not shown in this figure1.Table 2: Evaluated Software/Firmware versionSoftware/FirmwareItemSystem SoftwareWorkCentre 56XXMBCWorkCentre 56XXSBC021.120.060.00015025.054.060.000151For installation, the optional FAX card must be fitted into the machine.

SIP software controls theCopy Controller and is able to interface with all other softwarecomponents. IOT software controls the marking engine that prints topaper. DADH software controls the input tray. Finisher software controlsthe optional Finisher attachment. FAX software resides on the FAX boardand controls some fax functions. The System software manages overallsystem function while the Network Controller software resides on theNetwork Controller and controls all network functions.The TOE’s physical interfaces include a power port, Ethernet port, nonfunctional USB host ports, optional target USB and parallel ports, serialports, FAX ports (if the optional FAX card is installed), Local UserInterface (LUI) with keypad, a document scanner, a document feeder anda document output.1.3.2. Logical Scope of the TOEThe logical scope of the TOE includes all software and firmware that areinstalled on the product (see Table 2). The TOE logical boundary iscomposed of the security functions provided by the product.The following security functions are controlled by the TOE: Image Overwrite (TSF IOW)Authentication (TSF AUT)Network Identification (TSF NET ID)Security Audit (TSF FAU).Cryptographic Operations (TSF FCS)Management Data Protection – SSL (TSF FDP SSL)User Data Protection – IP Filtering (TSF FDP FILTER)Information Flow Security (TSF FLOW)Security Management (TSF FMT)User Data Protection - AES (TSF EXP UDE)1.3.2.1. Image Overwrite (TSF IOW)The TOE has an “Image Overwrite” function that overwrites files createdduring the printing, network scan, scan-to-email, and LanFax processes.This overwrite process is implemented in accordance with DoD 5200.28-Mand will be activated at the completion of each print, network scan, scan toe-mail, or LanFax job, once the MFD is turned back on after a powerfailure or on demand of the MFD system administrator.The TOE has an “Image Overwrite” function that overwrites files createdduring the embedded fax process. This overwrite process is implemented13 Copyright 2009 Xerox Corporation, All rights reserved

The embedded fax card flash memory overwrite isnot compliant with DoD 5200.28-M. LanFax jobs are overwritten on thehard disk after the image is transferred from the Network Controller toCopy Controller, and zeroized on the fax card flash memory once theimage has been sent. The Fax mailbox and dial directory are onlyzeroized when the administrator commands a full On-Demand ImageOverwrite (ODIO) operation.User image files associated with the Copy/Print, Store and Reprint featuremay be stored long term for later reprinting. When a job is selected forreprint, the stored job is resubmitted to the system. Temporary filescreated during processing are overwritten at the completion of the jobusing the 5200.28-M algorithm. The stored jobs are not overwritten untilthe jobs are deleted by the user, or when the System Administratorexecutes a full on-demand image overwrite. A standard ODIO overwritesall files written to temporary storage areas of the HDD and zeroizes thetemporary storage areas of the fax card flash memory. A full ODIOoverwrites those files as well as the Fax mailbox/dial directory, Scan tomailbox data, and all files that have been stored at the request of a uservia Copy/Print, Store and Reprint jobs.Copy jobs are not written to the hard drive and need not to be overwritten.Copy/Print, Store and Reprint jobs are written to the hard drive so thatthey may be reprinted at a later time; therefore, they will be overwrittenwhen a full on-demand image overwrite is performed. Embedded FAXjobs are written to flash memory and are overwritten at the completion ofeach job or on demand of the MFD system administrator. The embeddedfax card flash memory overwrite is not compliant with DoD 5200.28-M.1.3.2.2. Authentication (TSF AUT)The TOE requires a system administrator to authenticate before grantingaccess to system administration functions. The system administrator hasto enter a password at either the Web User Interface or the Local UserInterface. The password will be obscured2 as it is being entered.Identification of the system administrator at the Local User Interface isexplicit -- the administrator will identify themselves by entering theusername “admin” in the authentication window. Identification of thesystem administrator at the Web user Interface is explicit -- the2The LUI obscures input with the asterisk character. The specific character used to obscure input at the WebUI is browserdependent14 Copyright 2009 Xerox Corporation, All rights reserved
Xerox WorkCentre 5632/5638/5645/5655/5665/5675/5687Multifunction Systems Security Targetadministrator will identify themselves by entering the username “admin” inthe authentication dialog window.1.3.2.3. Network Identification (TSF NET ID)The TOE can prevent unauthorized use of the installed network options(network scanning, scan-to-email, and LanFax); the network optionsavailable are determined (selectable) by the system administrator. Toaccess a network service, the user is required to provide a user name andpassword, which is then validated by the designated authentication server(a trusted remote IT entity). The user is not required to login to thenetwork; the account is authenticated by the server as a valid user. Theremote authentication services supported by the TOE are: LDAP v4,Kerberos v5 (Solaris), Kerberos v5 (Windows 2000/2003), NDS (Novell4.x, 5.x), and SMB (Windows NT.4x/2000/2003). The cryptography usedby remote authentication services has been scoped out of the evaluation.Additionally the MBC model of the TOE can be configured to acceptCommon Access Cards as a means of network authentication for users toaccess the installed network options. When using the Common AccessCard method of authentication the Common Access Card performsauthentication for the TOE via PIN number. The TOE can not gain accessto the identification information on the access card until a valid pin numberhas been entered by the user. The TOE obscures pin number entry withasterisks when it is entered by the user.1.3.2.4. Security Audit (TSF FAU)The TOE generates audit logs that track events/actions (e.g.,print/scan/fax job submission) to users (based on network login). Theaudit logs, which are stored locally in a 15000 entry circular log, areavailable to TOE administrators and can be exported for viewing andanalysis. SSL v3.1 must be configured in order for the systemadministrator to download the audit records; the downloaded audit recordsare in comma separated format so that they can be imported into anapplication such as Microsoft Excel .1.3.2.5. Cryptographic Operations (TSF FCS)The TOE utilizes data encryption (RSA, TDES, AES), key establishment(RSA) and cryptographic checksum generation and secure hashcomputation (SHA-1) to support secure communication between the TOEand remote trusted products. Those packages include provisions for thegeneration of checksum/hash values and meet the following standards:3DES – NIST 800-67 (CAVP Certificate No. 990); SHA-1 – FIPS-180-2(CAVP Certificate No. 1331), AES-256-FIPS-197 (CAVP Certificate No.1472), SSLv3.1, RSA - FIPS 186-2 (CAVP Certificate No. 719)15 Copyright 2009 Xerox Corporation, All rights reserved

Management Data Protection – SSL(TSF FDP SSL)The TOE provides support for SSL and allows the TOE to act as either anSSL server, or SSL client, depending on the function the TOE isperforming (SSLSec SFP). SSL v3.1 must be enabled before the systemadministrator can retrieve the audit log. SSL functionality also permits theTOE to be administered from the Web UI.
