SECURITY TARGET INTRODUCTION This Chapter presents Security Target (ST) identification information and an overview of the ST. An ST contains the information technology (IT) security requirements of an identified Target of Evaluation (TOE) and specifies the functional and assurance security measures offered by that TOE to meet stated requirements. An ST principally defines: a) A security problem expressed as a set of assumptions about the security aspects of the environment, a list of threats that the product is intended to counter, and any known rules with which the product must comply (Chapter 3, TOE Security Environment). b) A set of security objectives and a set of security requirements to address the security problem (Chapters 4, 5 and 6, Security Objectives, Extended Components Definition, and IT Security Requirements, respectively). c) The IT security functions provided by the TOE that meet the set of requirements (Chapter 7, TOE Summary Specification). The structure and content of this ST comply with the requirements specified in the Common Criteria (CC), Part 1, Annex A, and Part 3, Chapter 11. 1.1. ST and TOE Identification This section provides information needed to identify and control this ST and its associated TOE. This ST targets Evaluation Assurance Level (EAL) 2 augmented with ALC_FLR.3. ST Title: Xerox ColorQube™ 9201/9202/9203 Security Target ST Version: 1.0 Revision Number: Revision 1.11 Publication Date: December 19, 2012 Authors: CSC Security Testing/Certification Laboratories, Xerox Corporation TOE Identification: Xerox ColorQube™ 9201/9202/9203 (see Section 1.3.1 for software version numbers) Xerox ColorQube™ 9201/9202/9203 Security Target 7 Copyright 2012 Xerox Corporation, All rights reserved ST Evaluator: CSC Security Testing/Certification Laboratories Keywords: Xerox, Multi Function Device, Image Overwrite, ColorQube™, Color, Mono, Hardcopy, Paper, Document, Printer, Scanner, Copier, Facsimile, Fax, Document Server, Document Storage and Retrieval, Nonvolatile storage, Residual data, Temporary data, Disk overwrite, Network interface, Shared communications medium, Multifunction Device, Multifunction Product, All-In- One, MFD, MFP, Network, Office, ISO/IEC 15408, Common Criteria, Protection Profile, Security Target 1.2. TOE Overview 1.2.1.Usage and Major Security Features The product is a multi-function device (MFD) that copies and prints in monochrome (black and white) and full color, with scan-to-email, workflow scan (including “scan-to-mailbox1 ”), and FAX options. A standard component of the TOE is the Image Overwrite Security package. This function forces any temporary image files created during a copy, print, scan or Fax jobs to be overwritten when those files are no longer needed. For reference, the architecture of the TOE is illustrated in Figure 1: Architectural Diagram of the TOE below: 1 In Xerox terminology, the terms “mailbox” and “folder” are used interchangeably, both referring to logical place holders under which files are stored. Xerox ColorQube™ 9201/9202/9203 Security Target 8 Copyright 2012 Xerox Corporation, All rights reserved Figure 1: Architectural Diagram of the TOE The optional Xerox Embedded Fax accessory, when purchased and installed, provides local analog fax capability over PSTN connections. Table 1 shows the configurations and printing speeds available in the various models of the TOE.

Xerox ColorQube™ 9201/9202/9203 Security Target 9 Copyright 2012 Xerox Corporation, All rights reserved An optional Finisher, which is not part of the TOE, provides “after print” services such as document collation and stapling. The hardware included in the TOE is shown in the figure below. This figure also shows an optional Finisher connected to the TOE at the right side of the picture and an optional Paper Feeder at the left side of the picture, neither of which are part of the TOE. Figure 2: Xerox ColorQube™ 9201/9202/9203 * Also shown are an optional Paper Feeder (left) and Finisher (right). The TOE stores temporary image data created during a copy, print, workflow scan, scan-to-email, internet fax and LanFax job on the single shared HDD. This temporary image data consists of the original data submitted and additional files created during a job. All partitions of the HDD used for spooling temporary files are encrypted. The encryption key is created dynamically on each power-up. The TOE provides an Image Overwrite function to enhance the security of the MFD. The Image Overwrite function overwrites temporary document image data at the completion of each job; also upon deletion of each job or of a workflow scan/fax file/mailbox in the following cases: at the instruction of the owner; after a reboot; once the TOE is turned back on after a power failure/unorderly shutdown; or on demand of the TOE system administrator. The optional Xerox Embedded Fax accessory provides analog FAX capability over Public Switched Telephone Network (PSTN) connections and also enables LanFax jobs, if purchased by the consumer. A separate non-volatile memory resource is dedicated to embedded fax, and the image files written to this memory are zeroized at the completion of a fax job. Xerox ColorQube™ 9201/9202/9203 Security Target 10 Copyright 2012 Xerox Corporation, All rights reserved Xerox’s Workflow Scanning Accessory is part of the TOE configuration. This accessory allows documents to be scanned at the device with the resulting image being sent via email, transfered to a remote (SSL scan) repository or kept in a private (scan) mailbox. All models of the TOE support auditing. The TOE generates audit logs that track events/actions (e.g., print/scan/fax job submission) to identified users. The audit logs, which are stored locally in a 15000 entry circular log, are available to TOE administrators and can be exported for viewing and analysis. SSL must be configured in order for the system administrator to download the audit records; the downloaded audit records are in comma separated format so that they can be imported into an application such as Microsoft Excel™. All models of the TOE support network security. The system administrator can enable and configure the network security support, as well as 802.1x device authentication. Filtering rules can be specified for IPv4 based on both address and port number. Additional network security support is based on SSL. When SSL support is enabled on the device, the following network security features can be enabled/configured: HTTPS support over both IPv4 and IPv6 (for both the device’s Web UI and secure workflow scan data transfer); system administrator download of the device’s audit log; IPSec support for IPP, lpr and port 9100 print jobs over IPv4 or IPv6; secure remote authentication (if supported by the remote authentication server) and secure network device management through SNMPv3. Scan-to-email and FAX data are not protected from sniffing by the IPSec or SSL support. The transmission of LanFax data over the Ethernet connection is protected by IPSec, but the transmission over the PSTN is not. IPSec and SNMPv3 can only be activated if SSL has been enabled and an SSL-based certificate (either “self-signed” or generated by an external Certificate Authority) has been loaded into the TOE via the Web UI. Once this has occurred SSL could be disabled; however, the TOE would no longer be in its evaluated configuration. The TOE controls and restricts the information flow from the external interfaces to the network controller (which covers the information flow to and from the internal network). The TOE requires users and system administrators to authenticate before granting access to user (copy, print, fax etc) or system administration functions via the Web User Interface (Web UI) or the Local User Interface (LUI). The user or system administrator must enter a username and password at either the Web User Interface or the Local User Interface. The password will be obscured3 as it is being entered. The TOE provides for user identification and authorization as configured by the system administrator. The TOE restricts (normal) users’ access to the documents. A user can only access his/her own documents. 3 The LUI obscures input with the asterisk character. The specific character used to obscure input at the WebUI is browser dependent. Xerox ColorQube™ 9201/9202/9203 Security Target 11 Copyright 2012 Xerox Corporation, All rights reserved The TOE can integrate with an IPv4 or IPv6 network with native support for dhcp/dhcpv6. The TOE supports the Common Access Card (CAC) standard and other methods (refer to chapter 1.3.2.3) for remote authentication. 1.2.2.TOE Type The TOE is a multi-function device (MFD) that provides copy and print (monochrome and color), document scanning (monochrome and color) and optional FAX services. 1.2.3.Required Non-TOE Hardware, Software and Firmware The TOE does not require any additional hardware, software or firmware in order to function as a multi-function device, however, the network security and fax flow features are only useful in environments where the TOE is connected to a network or PSTN. TSF_NET_ID is only available when one of the following remote authentication services is present on the network that the TOE is connected to: LDAP or Kerberos. CAC based TSF_NET_ID requires CAC compliant smart cards and smart card readers. 1.3. TOE Description This section provides context for the TOE evaluation by identifying the logical and physical scope of the TOE, as well as its evaluated configuration. 1.3.1.Physical Scope of the TOE The TOE is a Multi-Function Device (Xerox ColorQube™ 9201/9202/9203) that consists of a printer, copier, scanner, FAX (when purchased by the consumer), and email, as well as all Administrator and User guidance. The difference between the three models is their printing speed. The hardware included in the TOE is shown in Figure 2 above. This figure also shows an optional Finisher connected to the TOE at the right side of the picture and an optional Paper Feeder at the left side of the picture, neither of which are part of the TOE. The optional FAX card is not shown in this figure4 . The various software and firmware (“Software”) that comprise the TOE are listed in Table 2. A system administrator can ensure that they have a TOE by printing a configuration sheet and comparing the version numbers reported on the sheet to the table below. 4 For installation, the optional FAX card must be fitted into the machine. After powering on the machine, the Fax Install window pops up on the Local UI with step by step instructions for installation.

NOTE: For the remainder of this Security Target, the terms “Network Controller” and “Copy Controller” will refer to the “Network Controller” and “Copy Controller” software subsystems. Xerox ColorQube™ 9201/9202/9203 Security Target 13 Copyright 2012 Xerox Corporation, All rights reserved A customer of the TOE can determine whether the Xerox Embedded Fax accessory, Xerox Workflow Scan accessory and Image Overwrite Security Package5 are installed by reviewing the TOE configuration report. A consumer of the TOE can also determine that they have the evaluated version of the TOE by reviewing the TOE configuration report and comparing the version numbers to the content of Table 2, above. The Administrator and User guidance included in the TOE are listed in Table 3. A system administrator or user can ensure that they have the appropriate guidance by comparing the software version number to the version numbers listed in the table below. Table 3: System User and Administrator Guidance Title Document Number Date ColorQube™ 9201/9202/9203 System Administrator Guide v1.0 None May 2009 ColorQube™ 9201/9202/9203 Interactive User Guide 538E12581 May 2009 Secure Installation and Operation of Your ColorQube™ 9201/9202/9203 v1.3 None Mar 2012 The TOE’s physical interfaces include a power port, an Ethernet port, USB ports, serial ports, FAX ports (if the optional FAX card is installed), Local User Interface (LUI) with keypad, a document scanner, a document feeder and a document output. 1.3.2.Logical Scope of the TOE The logical scope of the TOE includes all software and firmware that are installed on the product (see Table 2). The TOE logical boundary is composed 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)  User Data Protection – SSL (TSF_FDP_SSL)  User Data Protection – IP Filtering (TSF_FDP_FILTER) 5 Xerox Embedded Fax accessory, Xerox Workflow Scan accessory and Image Overwrite Security Package are a part of the Network Controller or Copy Controller software package and do not have individual version identifiers. Xerox ColorQube™ 9201/9202/9203 Security Target 14 Copyright 2012 Xerox Corporation, All rights reserved  User Data Protection – IPSec (TSF_FDP_IPSec)  Network Management Security (TSF_NET_MGMT)  Information Flow Security (TSF_ FLOW)  Security Management (TSF_FMT)  User Data Protection – Disk Encryption (TSF_FDP_UDE) 1.3.2.1. Image Overwrite (TSF_IOW) The TOE has an “Immediate Image Overwrite” (IIO) function that overwrites files created during job processing. This IIO process automatically starts for all abnormally terminated copy, print, or scan jobs stored on the HDD and fax jobs stored on the fax card flash memory prior to coming “on line” when any of the following occurs: a reboot or once the MFD is turned back on after a power failure/unorderly shutdown. The TOE also has an “On-Demand Image Overwrite” (ODIO) function that overwrites the hard drive(s) and embedded fax card flash memory on-demand of the system administrator. The ODIO function operates in two modes: full ODIO and standard ODIO. A standard ODIO overwrites all files written to temporary storage areas of the HDD and zeroizes the temporary storage areas of the fax card flash memory. A full ODIO overwrites those files as well as the Fax mailbox/dial directory and Scan-to-mailbox data. Contents stored on the hard disk are overwritten using a three pass overwrite procedure. Contents of the embedded fax card flash memory are overwritten using a single-pass zeroization method. LanFax jobs are overwritten (using three pass overwrite) on the shared hard disk after the image is transferred from the Network Controller to Copy Controller, and zeroized on the fax card flash memory once the image has been sent. 1.3.2.2. Authentication (TSF_AUT) A user must authenticate by entering a username and password prior to being granted access to the Local UI or the Web UI. While the user is typing the password, the TOE obscures6 each character entered. Upon successful authentication, users are granted access based on their role and predefined privileges. Only a system administrator is allowed full access to the TOE including all the system administration functions. Each common user’s access is determined by which function (copy, scan, print, fax etc.) they have permission for. 6 The LUI obscures input with the asterisk character. The specific character used to obscure input at the WebUI is browser dependent Xerox ColorQube™ 9201/9202/9203 Security Target 15 Copyright 2012 Xerox Corporation, All rights reserved If configured for local authentication the system requires the system administrator to enter a username and password for each user. The system will authenticate the user against an internal database. By default, the Local UI will terminate any session that has been inactive for 60 minutes. By default, the Web UI will terminate any session that has been inactive for 15 minutes. The system administrator can configure both the Local UI and Web UI session timeouts to terminate an inactive session after some other period of time. 1.3.2.3. Network Identification (TSF_NET_ID) As an alternative to TSF_AUT, the TOE allows user name and password for a user to be validated by a designated authentication server (a trusted remote IT entity). The user is not required to login to the network; account information entered at Local UI or Web UI of the TOE is authenticated at the server instead of the TOE. The remote authentication services supported by the TOE in the evaluated configuration are: CAC authentication, LDAP v4, Kerberos v5 (Solaris) and Kerberos v5 (Windows 2000/2003). The TOE maintains the username from a successful authentication during the context of the job, and this value is entered into the audit log as the user name. By default, the Local UI will terminate any session that has been inactive for 60 minutes. By default, the Web UI will terminate any session that has been inactive for 15 minutes. The system administrator can configure both the Local UI and Web UI session timeouts to terminate an inactive session after some other period of time. 1.3.2.4. Security Audit (TSF_FAU) The TOE generates audit logs that track events/actions (e.g., copy/print/scan/fax job completion) to identified users. The audit logs, which are stored locally in a 15000 entry circular log, are available to TOE administrators and can be exported for viewing and analysis. SSL must be configured in order for the system administrator to download the audit records; the downloaded audit records are in comma separated format so that they can be imported into an application such as Microsoft Excel™. 1.3.2.5. Cryptographic Operations (TSF_FCS) The TOE utilizes data encryption (AES, RSA, RC4, DES, TDES) and cryptographic checksum generation and secure hash computation (MD5 and SHA-1), as provided by the OpenSSL cryptographic libraries, to support secure communication between the TOE and remote trusted products. Those packages include provisions for the generation and destruction of cryptographic keys and checksum/hash values and meet the following standards: AES-256-FIPS-197, 3DES – FIPS-42-2, FIPS-74, FIPS-81; MD5 – RFC1321; SHA-1 – FIPS-186, SSLv3, and SNMPv3. Xerox ColorQube™ 9201/9202/9203 Security Target 16 Copyright 2012 Xerox Corporation, All rights reserved NOTE: The strength of the cryptographic algorithms supported by the TOE is not part of the evaluation. The following table identifies relevant FIPS certificates. Cryptographic Operations Cryptographic Algorithm Key Sizes (bits) Standards / CAVP* Symmetric encryption and decryption Triple DES (CBC) 168 FIPS 46-3 (cert #826 and #1174) AES (CBC) 256 FIPS 197 (cert #1131 and #1821) Digital signature generation and verification RSA 1024 FIPS 186-3 (cert #914) Message digest SHA-1 N/A FIPS 180-3 (cert #1599) Message authentication HMAC 160 FIPS 198 (cert #644 and #1076) *Cryptographic Algortithm Validation Program (CAVP) certificates 1.3.2.6. User Data Protection – SSL (TSF_FDP_SSL) The TOE provides support for SSL through the use of the OpenSSL cryptographic libraries, and allows the TOE to act as either an SSL server or SSL client, depending on the function the TOE is performing. SSL must be enabled before setting up either IPSec, SNMPv3, or before the system administrator can retrieve the audit log. The SSL functionality also permits the TOE to be securely administered from the Web UI, as well as being used to secure the connection between the TOE and the repository server when utilizing the remote scanning option. If the system administrator-managed function is enabled, then the TOE creates and enforces the informal security policy model, “All communications to the Web server will utilize SSL (HTTPS).” As provided for in the SSLv3 standard, the TOE will negotiate with the client to select the encryption standard to be used for the session, to include operating in backward-compatible modes for clients that do not support SSLv3. SSL does not protect scan-to-email, LanFax or FAX data. The HTTPS web server supports both IPv4 and IPv6 protocols. 1.3.2.7. User Data Protection – IPSec (TSF_FDP_IPSec) Printing clients initiate the establishment of a security association with the MFD. Thereafter, all IP-based traffic to and from this destination will pass through IPSec until either end powers down, or resets, after which IPSec must be reestablished. The use of IPSec for communication with a particular destination is based on the presumed address of the printing client. IPSec does not protect scan-to-email or FAX data. The transmission of LanFax data over the Ethernet connection is protected by IPSec, but the transmission over the PSTN is not. The TOE implements IPSec for both IPv4 and IPv6; however, IPSec is not available for AppleTalk or IPX. Note: The TOE cannot enforce the IPSec (TSF_FDP_IPSec) security function when it is configured for AppleTalk or IPX networks. Xerox ColorQube™ 9201/9202/9203 Security Target 17 Copyright 2012 Xerox Corporation, All rights reserved 1.3.2.8. User Data Protection – Disk Encryption (TSF_FDP_UDE) The TOE utilizes data encryption (AES) and cryptographic checksum generation and secure hash computation (SHA-1), as provided by the Loop_AES cryptographic libraries, to support encryption and decryption of designated portions of the hard disk(s) where user files may be stored. Those packages include provisions for the generation and destruction of cryptographic keys and meet the following standards: AES-256-FIPS-197. AES data encryption and its associated cryptographic keys are used to encrypt and decrypt all areas of the hard drive where user jobs are temporarily stored for processing. NOTE: the strength of the cryptographic algorithms supported by the TOE is not part of the evaluation. 1.3.2.9. User Data Protection – IP Filtering (TSF_FDP_FILTER) The TOE provides the ability for the system administrator to configure a network information flow control policy based on a configurable rule set. The information flow control policy (IPFilter SFP) is generated by the system administrator specifying a series of rules to “accept,” “deny,” or “drop” packets. These rules include a listing of IP addresses that will be allowed to communicate with the TOE. The IP Filter supports the construction of IPv4 filtering policies. Additionally, rules can be generated specifying filtering options based on port number given in the received packet. IP Filtering is not available for IPv6, AppleTalk or IPX; however, the effect of IP Filtering can be accomplished for IPv6 by configuring IPSec associations. 1.3.2.10. Network Management Security (TSF_NET_MGMT) The TOE supports SNMPv3 as part of its security solution (SNMPSec SFP). The SNMPv3 protocol is used to authenticate each SNMP message, as well as provide encryption of the data as described in RFC 3414. 1.3.2.11. Information Flow Security (TSF_FLOW) The TOE controls and restricts the data/information flow from the Local User Interface (LUI), document scanner and document feeder to the network controller hardware or software (which covers the information flow to and from the internal network). All data and/or commands received from these interfaces are processed and in most cases transformed by the copy controller before submitted to the network controller. The network controller further processes the data before sending them to the internal network. The TOE controls and restricts the information flow between the PSTN port of the optional FAX processing board (if installed) and the network controller hardware or software. Data and/or commands cannot be sent to the internal Xerox ColorQube™ 9201/9202/9203 Security Target 18 Copyright 2012 Xerox Corporation, All rights reserved network via the PSTN. A direct connection from the internal network to external entities by using the telephone line of the TOE is also denied. If the optional FAX board is not installed, an information flow from or to the FAX port is not possible at all. 1.3.2.12. Security Management (TSF_FMT) Only authenticated system administrators can enable or disable the Immediate Image Overwrite function, change the system administrator password, and start an On Demand Image Overwrite operation. While IIO can be disabled, doing so will remove the TOE from its evaluated configuration. Additionally, only authenticated system administrators can assign authorization privileges to users, establish a recurrence schedule for “On Demand Image Overwrite, enable/disable SSL support, enable/disable and configure IPSec, enable/disable and configure SNMPv3, create/install X.509 certificates, enable/disable and download the audit log, enable/disable and configure (rules) IP filtering, configure inactive session timeout settings, enable/disable disk encryption, enable/disable use of Common Access Cards, verify TOE software binary code integrity, or enable/disable and configure 802.1x. User’s access to the TOE functions, Job or Image Data stored inside the TOE is restricted, in accordance with the applicable TOE Security Policies. The TOE is capable of verifying the integrity of the TSF at the request of the administrator. 1.4. Evaluated Configuration In its evaluated configuration, IIO and ODIO (the Image Overwrite Security Package) are installed and enabled on the TOE; SSL is enabled on the TOE; and User Authorization is enabled on the TOE. The FAX (Xerox Embedded Fax accessory) option, if purchased by the consumer, is installed and enabled on the TOE. The LanFax option is included in the evaluated configuration of the TOE. USB Direct Printing is not included in the evaluated configuration of the TOE. In its evaluated configuration, the following options should be disabled:  Network Accounting  Copy/Print, Store and Reprint  SMart eSolutions  Xerox Extensible Interface Platform (EIP)  USB direct printing Xerox ColorQube™ 9201/9202/9203 Security Target 19 Copyright 2012 Xerox Corporation, All rights reserved Please see http://www.xerox.com/information-security/product/enus.html for more specific information about maintaining the security of this TOE.

This Security Target claims demonstrable conformance to both IEEE Std. 2600.2™-2009 and NIAP CCEVS Policy #20. Xerox ColorQube™ 9201/9202/9203 Security Target 21 Copyright 2012 Xerox Corporation, All rights reserved This Security Target claims conformance to the EAL2 package augmented with ALC_FLR.3, and the following additional packages from the “U.S. Government Protection Profile for Hardcopy Devices Version 1.0 (IEEE Std. 2600.2-2009)” Protection Profile dated 26 February 2010:  2600.2-PRT, SFR Package for Hardcopy Device Print Functions, Operational Environment B  2600.2-SCN, SFR Package for Hardcopy Device Scan Functions, Operational Environment B  2600.2-CPY, SFR Package for Hardcopy Device Copy Functions, Operational Environment B  2600.2-FAX, SFR Package for Hardcopy Device Fax Functions, Operational Environment B  2600.2-DSR, SFR Package for Hardcopy Device Document Storage and Retrieval Functions, Operational Environment B  2600.2-SMI, SFR Package for Hardcopy Device Shared-medium Interface Functions, Operational Environment B 2.4. Rationale The TOE type in this ST (multifunction or hardcopy device) is the same as the TOE type for IEEE 2600.2. The Security Problem Definition (Threats, Assumptions and Organizational Security Policies) and Objectives have been copied directly from IEEE Std. 2600.2-2009 and have not been modified. One security objective for the TOE (O.AUDIT_STORAGE.PROTECTED) has been added in accordance to application notes 7 from IEEE Std. 2600.2-2009. Only one security objective for the IT environment (OE.USER.AUTHENTICATED) has been added in accordance to application notes 37, 42 and 43 from IEEE Std. 2600.2-2009. The statement of Security Requirements contains the SFRs from IEEE Std. 2600.2-2009 as well as additional SFRs that are taken from CC Part 2. By including all of the SFRs from IEEE Std. 2600.2-2009 and including additional SFRs (none of which conflict with each other), the statement of Security Requirements is necessarily at least as strict as the statement in IEEE Std. 2600.2-2009, if not more strict. The rationales for objectives, threats, assumptions, organizational security policies and security requirements have been copied from IEEE Std. 2600.2-2009 and have been augmented to address the requirements that have been added from CC Part 2. The IEEE Std. 2600.2-2009 statement of Common Security Functional Requirements has been augmented with additional (including iterated) SFRs from CC Part 2: Family Augmentation Audit FAU_SAR.1, FAU_SAR.2, FAU_STG.1, FAU_STG.4 Cryptographic Support FCS_CKM.1 (SSL), FCS_CKM.2 (SSL 1), FCS_CKM.2 (SSL 2), FCS_COP.1 (SSL), FCS_CKM.1 (IPSEC), FCS_COP.1 (IPSEC 1), FCS_COP.1 (IPSEC 2), FCS_CKM.1 (SNMP), FCS_COP.1 Xerox ColorQube™ 9201/9202/9203 Security Target 22 Copyright 2012 Xerox Corporation, All rights reserved (SNMP), FCS_CKM.1 (UDE), FCS_CKM.4 User Data Protection FDP_ACC.1 (MGMT), FDP_ACF.1 (MGMT) Identification and Authentication FIA_UAU.7 Security Management FMT_MOF.1 (FMT 1), FMT_MOF.1 (FMT 2) The following packages from IEEE Std. 2600.2-2009 have been augmented with additional (including iterated) SFRs from CC Part 2: Package Augmentation PRT SCN CPY FAX FDP_RIP.1 (IOW 2) DSR FCS_COP.1(UDE) SMI FDP_IFC.1 (FILTER), FDP_IFF.1 (FILTER), FDP_UCT.1 (IPSEC), FDP_UIT.1 (IPSEC), FDP_UCT.1 (SSL), FDP_UIT.1 (SSL), FDP_UCT.1 (SNMP), FDP_UIT.1 (SNMP), FTP_TRP.1 (IPSEC), FTP_TRP.1 (SSL), FTP_TRP.1 (SNMP) Xerox ColorQube™ 9201/9202/9203 Security Target 23 Copyright 2012 Xerox Corporation, All rights reserved 3. SECURITY PROBLEM DEFINITION The Security Problem Definition describes assumptions about the operational environment in which the TOE is intended to be used and represents the conditions for the secure operation of the TOE. Note: The content in this section appears exactly as it does in IEEE Std. 2600.2-2009 and is copied here for completeness. 3.1. Definitions 3.1.1.Users Users are entities that are external to the TOE and which interact with the TOE. There may be two types of Users: Normal and Administrator. Table 4: Users Designation Definition U.USER Any authorized User. U.NORMAL A User who is authorized to perform User Document Data processing functions of the TOE U.ADMINISTRATOR A User who has been specifically granted the authority to manage some portion or all of the TOE and whose actions may affect the TOE security policy (TSP). Administrators may possess special privileges that provide capabilities to override portions of the TSP. 3.1.2.Objects (Assets) Objects are passive entities in the TOE, that contain or receive information, and upon which Subjects perform Operations. In this Security Target, Objects are equivalent to TOE Assets. There are three types of Objects: User Data, TSF Data, and Functions. 3.1.2.1. User Data User Data are data created by and for Users and do not affect the operation of the TOE Security Functionality (TSF). This type of data is composed of two objects: User Document Data, and User Function Data. Xerox ColorQube™ 9201/9202/9203 Security Target 24 Copyright 2012 Xerox Corporation, All rights reserved Table 5: User Data Designation Definition D.DOC User Document Data consists of the information contained in a user’s document. This includes the original document itself in either hardcopy or electronic form, image data, or residually-stored data created by the hardcopy device while processing an original document and printed hardcopy output. D.FUNC User Function Data are the information about a user’s document or job to be processed by the TOE. 3.1.2.2. TSF Data TSF Data is data created by and for the TOE and might affect the operation of the TOE. This type of data is composed of two objects: TSF Protected Data and TSF Confidential Data. The TSF Data assets for this TOE has been categorized according to whether they require protection from unauthorized alteration (TSF Protected Data) or protection from both unauthorized disclosure and unauthorized alteration (TSF Confidential Data). The data assets have been identified and categorized in Table 6: TSF Data and Table 7: TSF Data Categorization below. Table 6: TSF Data Designation Definition D.PROT TSF Protected Data are assets for which alteration by a User who is neither an Administrator nor the owner of the data would have an effect on the operational security of the TOE, but for which disclosure is acceptable. D.CONF TSF Confidential Data are assets for which either disclosure or alteration by a User who is neither an Administrator nor the owner of the data would have an effect on the operational security of the TOE. Table 7: TSF Data Categorization TSF Protected Data TSF Confidential Data Configuration data Audit Log Device and network status information and configuration settings Cryptographic keys (SNMPv3 – privacy key, IPSec) Device service and diagnostic data X.509 Certificate (SSL) User IDs and Passwords User Access Permissions SNMPv3 authentication key 802.1x Credentials and Configuration IP filter table (rules) Email address for fax forwarding Application Note: IEEE Std. 2600.2-2009 defines D.PROT and D.CONF, and requires the ST author to categorize all TSF data as one of these two types: data that should be protected, but does not affect the operational security of the TOE if it is disclosed (D.PROT), and data that does affect the operational security of the TOE if it is disclosed (D.CONF). Xerox ColorQube™ 9201/9202/9203 Security Target 25 Copyright 2012 Xerox Corporation, All rights reserved 3.1.2.3. Functions Functions perform processing, storage, and transmission of data that may be present in HCD products. These functions are used by SFR packages, and are identified and defined in the table below. Table 8: SFR Package Functions for IEEE Std. 2600.2-2009 Designation Definition F.PRT Printing: a function in which electronic document input is converted to physical document output F.SCN Scanning: a function in which physical document input is converted to electronic document output F.CPY Copying: a function in which physical document input is duplicated to physical document output F.FAX Faxing: a function in which physical document input is converted to a telephone-based document facsimile (fax) transmission, and a function in which a telephone-based document facsimile (fax) reception is converted to physical document output F.DSR Document storage and retrieval: a function in which a document is stored during one job and retrieved during one or more subsequent jobs F.SMI Shared-medium interface: a function that transmits or receives User Data or TSF Data over a communications medium which, in conventional practice, is or can be simultaneously accessed by multiple users, such as wired network media and most radio-frequency wireless media 3.1.3.Operations Operations are a specific type of action performed by a Subject on an Object. In this Security Target, five types of operations are considered: those that result in disclosure of information (Read), those that result in alteration of information (Create, Modify, Delete), and those that invoke a function (Execute). 3.1.4.Channels Channels are the mechanisms through which data can be transferred into and out of the TOE. In this Security Target, four types of Channels are allowed: Private Medium Interface: mechanisms for exchanging information that use (1) wired or wireless electronic methods over a communications medium which, in conventional practice, is not accessed by multiple simultaneous Users; or, (2) Operator Panel and displays that are part of the TOE. It is an input-output channel. Shared-medium Interface: mechanisms for exchanging information that use wired or wireless network or non-network electronic methods over a communications medium which, in conventional practice, is or can be simultaneously accessed by multiple Users. It is an input- output channel. Xerox ColorQube™ 9201/9202/9203 Security Target 26 Copyright 2012 Xerox Corporation, All rights reserved Original Document Handler: mechanisms for transferring User Document Data into the TOE in hardcopy form. It is an input channel. Hardcopy Output Handler: mechanisms for transferring User Document Data out of the TOE in hardcopy form. It is an output channel. In practice, at least one input channel and one output channel would be present in any HCD configuration, and at least one of those channels would be either an Original Document Handler or a Hardcopy Output Handler. 3.2. Assumptions The Security Objectives and Security Functional Requirements defined in subsequent sections of this Security Target are based on the condition that all of the assumptions described in this section are satisfied. Table 9: Assumptions for the TOE Assumption Definition A.ACCESS.MANAGED The TOE is located in a restricted or monitored environment that provides protection from unmanaged access to the physical components and data interfaces of the TOE. A.USER.TRAINING TOE Users are aware of the security policies and procedures of their organization, and are trained and competent to follow those policies and procedures. A.ADMIN.TRAINING Administrators are aware of the security policies and procedures of their organization, are trained and competent to follow the manufacturer’s guidance and documentation, and correctly configure and operate the TOE in accordance with those policies and procedures. A.ADMIN.TRUST Administrators do not use their privileged access rights for malicious purposes. 3.3. Threats 3.3.1.Threats Addressed by the TOE This security problem definition addresses threats posed by four categories of threat agents: a) Persons who are not permitted to use the TOE who may attempt to use the TOE b) Persons who are authorized to use the TOE who may attempt to use TOE functions for which they are not authorized. c) Persons who are authorized to use the TOE who may attempt to access data in ways for which they not authorized. d) Persons who unintentionally cause a software malfunction that may expose the TOE to unanticipated threats. Xerox ColorQube™ 9201/9202/9203 Security Target 27 Copyright 2012 Xerox Corporation, All rights reserved The threats and policies defined in this Security Target address the threats posed by these threat agents. This section describes threats to assets described in Section 3.1.2.

Organizational Security Policies This section describes the Organizational Security Policies (OSPs) that apply to the TOE. OSPs are used to provide a basis for security objectives that are commonly desired by TOE Owners in this operational environment, but for which it is not practical to universally define the assets being protected or the threats to those assets.

SECURITY OBJECTIVES The purpose of the security objectives is to detail the planned response to a security problem or threat. Threats can be directed against the TOE or the security environment or both, therefore, the CC identifies two categories of security objectives:  Security objectives for the TOE, and  Security objectives for the environment. Note: The content in this section appears exactly as it does in IEEE Std. 2600.2-2009 and is copied here for completeness. 4.1.

Security Objectives for the Operational Environment This section describes the security objectives that must be fulfilled by IT methods in the IT environment of the TOE. Table 14: Security Objectives for the IT Environment Objective Definition OE.AUDIT_STORAGE.PROTECTED If audit records are exported from the TOE to another trusted IT product, the TOE Owner shall ensure that those records are protected from unauthorized access, deletion and modifications. OE.AUDIT_ACCESS.AUTHORIZED If audit records generated by the TOE are exported from the TOE to another trusted IT product, the TOE Owner shall ensure that those records can be accessed in order to detect potential security violations, and only by authorized persons OE.INTERFACE.MANAGED The IT environment shall provide protection from unmanaged access to TOE external interfaces. OE.USER.AUTHENTICATED The IT environment shall provide support for user identification and authentication and protect the user credentials in transit when TOE operates in remote identification and authentication mode. 4.3. Security Objectives for the Non- IT Environment This section describes the security objectives that must be fulfilled by non-IT methods in the non-IT environment of the TOE. Table 15: Security Objectives for the Non-IT Environment Objective Definition OE.PHYSICAL.MANAGED The TOE shall be placed in a secure or monitored area that provides protection from unmanaged physical access to the TOE. OE.USER.AUTHORIZED The TOE Owner shall grant permission to Users to be authorized to use the TOE according to the security policies and procedures of their organization. OE.USER.TRAINED The TOE Owner shall ensure that Users are aware of the security policies and procedures of their organization, and have the training and competence to follow those policies and procedures. OE.ADMIN.TRAINED The TOE Owner shall ensure that TOE Administrators are aware of the security policies and procedures of their organization, have the training, competence, and time to follow the manufacturer’s guidance and documentation, and correctly configure and operate the TOE in accordance with those policies and procedures. OE.ADMIN.TRUSTED The TOE Owner shall establish trust that TOE Administrators will not use their privileged access rights for malicious purposes. Xerox ColorQube™ 9201/9202/9203 Security Target 30 Copyright 2012 Xerox Corporation, All rights reserved Objective Definition OE.AUDIT.REVIEWED The TOE Owner shall ensure that audit logs are reviewed at appropriate intervals for security violations or unusual patterns of activity. 4.4. Rationale for Security Objectives This section demonstrates that each threat, organizational security policy, and assumption are mitigated by at least one security objective for the TOE, and that those security objectives counter the threats, enforce the policies, and uphold the assumptions.

EXTENDED COMPONENTS DEFINTION This Security Target defines components that are extensions to Common Criteria 3.1 Release 2, Part 2. 5.1. FPT_FDI_EXP Restricted forwarding of data to external interfaces Family behaviour: This family defines requirements for the TSF to restrict direct forwarding of information from one external interface to another external interface. Many products receive information on specific external interfaces and are intended to transform and process this information before it is transmitted on another external interface. However, some products may provide the capability for attackers to misuse external interfaces to violate the security of the TOE or devices that are connected to the TOE’s external interfaces. Therefore, direct forwarding of unprocessed data between different external interfaces is forbidden unless explicitly allowed by an authorized administrative role. The family FPT_FDI_EXP has been defined to specify this kind of functionality. Component leveling: FPT_FDI_EXP.1 Restricted forwarding of data to external interfaces, provides for the functionality to require TSF controlled processing of data received over defined external interfaces before this data is sent out on another external interface. Direct forwarding of data from one external interface to another one requires explicit allowance by an authorized administrative role.

Audit: FPT_FDI_EXP.1 The following actions should be auditable if FAU_GEN Security Audit Data Generation is included in the PP/ST: a) There are no auditable events foreseen. Rationale: Quite often a TOE is supposed to perform specific checks and process data received on one external interface before such (processed) data is allowed to be transferred to another external interface. Examples are firewall systems but also other systems that require a specific work flow for the incoming data before it can be transferred. Direct forwarding of such data (i. e. without processing the data first) between different external interfaces is therefore a function that – if allowed at all – can only be allowed by an authorized role. It has been viewed as useful to have this functionality as a single component that allows specifying the property to disallow direct forwarding and require that only an authorized role can allow this. Since this is a function that is quite common for a number of products, it has been viewed as useful to define an extended component. The Common Criteria defines attribute-based control of user data flow in its FDP class. However, in this Security Target, the authors needed to express the control of both user data and TSF data flow using administrative control instead of attribute-based control. It was found that using FDP_IFF and FDP_IFC for this purpose resulted in SFRs that were too unwieldy for refinement in a Security Target. Therefore, the authors decided to define an extended component to address this functionality. This extended component protects both user data and TSF data, and could therefore be placed in either the FDP or FPT class. Since its purpose is to protect the TOE from misuse, the authors believed that it was most appropriate to place it in the FPT class. It did not fit well in any of the existing families in either class, and this lead the authors to define a new family with just one member.

SECURITY REQUIREMENTS This section defines the IT security requirements that shall be satisfied by the TOE or its environment: The CC divides TOE security requirements into two categories:  Security functional requirements (SFRs) (such as, identification and authentication, security management, and user data protection) that the TOE and the supporting evidence need to satisfy to meet the security objectives of the TOE.  Security assurance requirements (SARs) that provide grounds for confidence that the TOE and its supporting IT environment meet its security objectives (e.g., configuration management, testing, and vulnerability assessment). These requirements are discussed separately within the following subsections. 6.1. Conventions All operations performed on the Security Functional Requirements or the Security Assurance Requirements need to be identified. For this purpose the following conventions shall be used.  Assignments will be written in [normal text with brackets]  Selections will be written in underlined and italic text.  Refinements will be written bold  Iterations will be performed on components and functional elements. The component ID defined by the Common Criteria (e.g. FDP_IFC.1) will be extended by an ID for the iteration (e.g. “(SSL)”). The resulting component ID would be “FDP_IFC.1 (SSL)”.  Where an iteration is identified in rationale discussion as “all”, the statement applies to all iterations of the requirement (e.g. “FCS_CKM.1 (all)”)  SFRs and TSPs that appear in the IEEE 2600.2 are marked as such; all unmarked SFRs have been added to this ST from CC Part 2. 6.2. TOE Security Policies This chapter contains the definition of security policies which must be enforced by the TSF. Xerox ColorQube™ 9201/9202/9203 Security Target 38 Copyright 2012 Xerox Corporation, All rights reserved 6.2.1.Information Flow Control Policy (TSP_FLOW) The security function “Information Flow” (TSF_FLOW) (see section 1.3.2.11) restricts the information flow between the PSTN port and the internal network by implementing a store-and- forward principle. The following policy defines the rules according to which TSF_FLOW shall restrict the information flow, if the fax is enabled:  Only the copy controller (see section 1.3.2.11) may copy image information and job data (e.g. the telephone number of the other fax machine) from and to a shared memory area on the FAX board.  RECEIVING FAX: The fax controller must have terminated the PSTN connection before informing the copy controller about the fax that was received.  SENDING FAX: The copy controller must have finished the copy operation of the fax image to the shared memory area of the FAX board before informing the fax controller to send the fax. 6.2.2.SSLSec SFP (TSP_SSL) The security function “User Data Protection -- SSL” (TSF_FDP_SSL) requires that SSL is enabled so that Web-based network traffic to and from the TOE will be encrypted using SSL This policy will be enforced on:  SUBJECTS: Web clients.  INFORMATION: All web-based traffic to and from that destination.  OPERATIONS: HTTP commands. 6.2.3.IP Filter SFP (TSP_FILTER) The security function “User Data Protection -- IP Filtering” (TSF_FDP_FILTER) requires that network traffic to and from the TOE will be filtered in accordance with the rules defined by the system administrator at the Web User Interface configuration editor for IP Filtering. This policy will be enforced on:  SUBJECTS: External entities that send network traffic to the TOE.  INFORMATION: All IP-based traffic to and from that destination.  OPERATIONS: Pass network traffic. Note: The TOE cannot enforce the IP Filtering (TSP_FILTER) when it is configured for IPv6, AppleTalk or IPX networks. 6.2.4.IPSec SFP (TSP_IPSEC) The security function “User Data Protection -- IPSec” (TSF_FDP_IPSec) requires that network traffic to and from the TOE will be encrypted when the printing client initiates IPSec encryption. This policy will be enforced on: Xerox ColorQube™ 9201/9202/9203 Security Target 39 Copyright 2012 Xerox Corporation, All rights reserved  SUBJECTS: Printing clients.  INFORMATION: All lpr and port 9100 traffic to and from that destination.  OPERATIONS: Print jobs. 6.2.5.SNMPSec SFP (TSP_SNMP) The security function “Network Management Security” (TSF_NET_MGMT) requires that the TOE applies SNMPv3 so that network traffic to and from the TOE will be encrypted in accordance with SNMPv3. This policy will be enforced on:  SUBJECTS: Remote SNMPv3 hosts.  INFORMATION: All SNMPv3 traffic to and from that destination.  OPERATIONS: SNMPv3 commands and messages. 6.2.6.PrivUserAccess SFP (TSP_FMT) The security function “Security Management” (TSF_FMT) restricts management of TOE security functions to the authorized system administrator. 6.2.7.User Access Control SFP (UAC_SFP) (IEEE Std. 2600.2-2009) The Security Function Policy (SFP) described in Table 18: User Access Control SFP is referenced by the Class FDP SFRs.

Application Note: IEEE Std. 2600.2-2009 specifies the contents of FDP_ACC.1 for each function package that is claimed by a ST and a Common Access Control SFP for D.FUNC and D.DOC (Operation: read). In this ST, the SFPs for each package are combined with the Common Access Control SFP then refined to form Table 18 (User Access Control SFP). User Access Control SFP represents more detail and a more restrictive requirement than the combination of package SFPs and the Common Access Control SFP. Hence the ST is conformant to IEEE Std. 2600.2-2009. Application Note: A document (D.DOC) is “owned” by a User (U.User) if that document was created or submitted to the TOE by that User. The only exception are documents received as fax Xerox ColorQube™ 9201/9202/9203 Security Target 41 Copyright 2012 Xerox Corporation, All rights reserved (D.DOC +FAXIN), for which the system administrators are considered as the owner. This is in conformance to IEEE Std. 2600.2-2009 application note 94 and 95. Application Note: Access control rules for the “Create” Operation are not specified because typically, any authorized U.User can create his/her own documents and cannot create documents that are owned by another User. Application Note: IEEE Std. 2600.2-2009 (table 23) defined attribute +DSR does not apply to D.FUNC, and in this ST is only applicable to D.DOC with attribute +SCN. Attribute +SMI does not apply to this SFP. 6.2.8.TOE Function Access Control SFP (TF_SFP) (IEEE Std. 2600.2-2009) Users (U.NORMAL) require explicit authorization from system administrators (U.ADMINISTRATOR) for them to be allowed to perform the following TOE Functions as defined in the IEEE Std. 2600.2-2009 SFR Packages in Section 12.3 via the Web UI or the LUI:  Print (PRT)  Scan (SCN)  Fax (FAX)  Copy (CPY)  Document Storage and Retrieval (DSR)  Transmit data via Shared-medium Interfaces (SMI) Any User who is authorized to establish an connection with the TOE through the Ethernet port is allowed to perform the following TOE Functions as defined in the IEEE Std. 2600.2-2009 SFR Packages in Section 12.3:  Print (PRT)  Fax (FAX) – LanFax only  Transmit data via Shared-medium Interfaces (SMI) 6.3.

FIA_USB.1.2 The TSF shall enforce the following rules on the initial association of user security attributes with the subjects acting on behalf of users: [subjects will be assigned the security attributes of the user that they are acting on behalf of]. FIA_USB.1.3 The TSF shall enforce the following rules governing changes to the user security attributes with the subjects acting on behalf of users: [security attributes of subjects acting on behalf of a user will not be changed while an action is in progress and cannot be changed by anyone but U.ADMINISTRATOR]. Application Note: For the purposes of this requirement, a “subject” is a process within the TOE that is acting (performing functions) on behalf of a user that is interacting with the TOE through its external interfaces. The subject will be assigned the permissions (security attributes) of the user and will act with only the permission set that the user holds. These permissions cannot be changed by the user; they can only be changed by the system administrator, and cannot be changed while an action is in progress. For example, if a process on the TOE is printing a document on behalf of a user and a system administrator revokes their permission to print, the user/subject pair will be denied further printing rights once the print job in progress has completed. 6.3.6.Class FMT: Security management 6.3.6.1.

Application Note: IEEE 2600.2 PP Application Note 116 states the following: “The ST Author can use this SFR to define the roles that are permitted to allow unmediated transmission between Interfaces. If unmediated transmission is never allowed, “Nobody” should be instantiated as the “authorized identified roles.” This extended component, as defined in IEEE 2600.2, does not provide a mechanism for specifying authorized identified roles. For this reason, the authorized identified role that is not included in this extended requirement claim should be Xerox ColorQube™ 9201/9202/9203 Security Target 67 Copyright 2012 Xerox Corporation, All rights reserved “Nobody”. Additionally, for this TOE, the restricted forwarding from the external interfaces to the network controller are architectural design features which cannot be configured; hence the dependencies on FMT_SMF.1 and FMT_SMR.1 are not met. 6.6. Rationale for Security Functional Requirements Table 23: Completeness of Security Functional Requirements and Table 24: Sufficiency of Security Functional Requirements below demonstrate the completeness and sufficiency of SFRs that fulfill the objectives of the TOE.

Rationale for Security Assurance Requirements This Security Target has been developed Using the “U.S. Government Protection Profile for Hardcopy Devices Version 1.0 (IEEE Std. 2600.2-2009)” and related SFR packages, EAL2+ augmented with ALC_FLR.2; which was created to describe Hardcopy Devices used in commercial information processing environments that require a relatively high level of document security, operational accountability and information assurance. The TOE environment will be exposed to only a low level of risk because it is assumed that the TOE will be located in a restricted or monitored environment that provides almost constant protection from unauthorized and unmanaged access to the TOE and its data interfaces. Agents cannot physically access any nonvolatile storage without disassembling the TOE. Agents have limited or no means of infiltrating the TOE with code to effect a change and the TOE self-verifies its executable code to detect unintentional malfunctions. As such, the Evaluation Assurance Level 2 is appropriate. While IEEE Std. 2600.2-2009 augments EAL2 with ALC_FLR.2, Flaw reporting procedures, this ST augments EAL2 with ALC_FLR.3, Systematic flaw remediation. ALC_FLR.3 is hierarchical to ALC_FLR.2 and encompasses all requirements of ALC_FLR.2 plus some additional requirements. ALC_FLR.3 ensures that instructions and procedures for the reporting and remediation of identified security flaws are in place and their inclusion is expected by the Xerox ColorQube™ 9201/9202/9203 Security Target 75 Copyright 2012 Xerox Corporation, All rights reserved consumers of this TOE, and that consumers of this TOE are automatically notified of flaws and changes to the TOE. 6.8.

The TOE does not give system administrators the option of managing or specifying default role values, permissive or otherwise, for the creation of user accounts. It is for these reasons that the dependencies on FMT_MSA.3 are not and cannot be expected to be met. 13 The dependency of FDP_IFF.1 (FILTER) on FMT_MSA.3 is not met because none of these functions support “a) managing the group of roles that can specify initial values; b) managing the permissive or restrictive setting of default values for a given access control SFP; c) management of rules by which security attributes inherit specified values.” (CC Part 2 Page 106). The TOE does not give system administrators the option of specifying default values, permissive or otherwise. In fact, these features are configured and, with the exception of IP Filter rules, cannot be modified by the system administrator other than to enable or disable them. It is for these reasons that the dependency on FMT_MSA.3 is not and cannot be expected to be met.

TOE SUMMARY SPECIFICATION This section presents an overview of the security functions implemented by the TOE. 7.1. TOE Security Functions This section presents the security functions performed by the TOE to satisfy the identified SFRs in Sections 6.3 and 6.5. For reference, the TOE architecture is depicted in Figure 1.  Image Overwrite (TSF_IOW)  Information Flow Security (TSF_FLOW)  System Authentication (TSF_AUT)  Network Identification (TSF_NET_ID)  Security Audit (TSF_FAU)  Cryptographic Support (TSF_FCS)  User Data Protection – SSL (TSF_FDP_SSL)  User Data Protection – IP Filtering (TSF_FDP_FILTER)  User Data Protection – IPSec (TSF_FDP_IPSec)  Network Management Security (TSF_NET_MGMT)  Security Management (TSF_FMT)  User Data Protection - Disk Encryption (TSF_FDP_UDE) 7.1.1.Image Overwrite (TSF_IOW) FDP_RIP.1 (IOW 1), FDP_RIP.1 (IOW 2) The TOE implements an image overwrite security function to overwrite all temporary files created during processing of jobs, files (images) of completed or deleted jobs or any files that are deleted16 . The network controller spools and processes documents to be printed or scanned. Temporary files are created as a result of this processing on a reserved section of the hard disk drive. The definition of this reserved section is statically stored within the TOE and cannot be manipulated. Immediately after the job has completed, the files are overwritten, and this is called Immediate Image Overwrite (IIO). 16 Files are stored inside mailboxes. They may be deleted by their owner through individual file deletions or deletion of the mailbox. Xerox ColorQube™ 9201/9202/9203 Security Target 81 Copyright 2012 Xerox Corporation, All rights reserved The embedded fax card buffers incoming and outgoing fax images in flash memory. Immediately after an embedded fax job has completed, the files are overwritten. The TOE automatically starts an IIO procedure for all abnormally terminated copy, print or scan jobs stored on the HDD and fax jobs on the fax card flash memory prior to coming “on line” when any of the following occurs: a reboot or once the MFD is turned back on after a power failure/unorderly shutdown. The image overwrite security function can also be invoked manually (on demand) by the system administrator (ODIO). Once invoked, the ODIO cancels all print and scan jobs, halts the printer interface (network), performs the overwrites, and then the network controller reboots. A scheduling function allows ODIO to be executed on a recurring basis as set up by the System Administrator. A standard On Demand Image Overwrite (ODIO) overwrites all files written to temporary storage areas of the HDD(s) and the temporary storage area of the Fax card flash memory. A full ODIO overwrites those files as well as the Fax mailbox/dial directory (in Fax card flash memory), and Scan to mailbox data. An ODIO cannot be aborted from either the WebUI or Local UI. TSF_IOW overwrites the contents of the reserved section on the hard disk using a three pass overwrite procedure. It overwrites the contents of the embedded fax card flash memory using a single-pass zeroization method. For example, LanFax jobs are overwritten (using three pass overwrite) on the shared hard disk after the image is transferred from the Network Controller to Copy Controller, and zeroized on the fax card flash memory once the image has been sent. 7.1.2.Information Flow Security (TSF_FLOW) FPT_FDI_EXP.1 The only physical Shared-medium interface of the TOE is the Ethernet port directly controlled by the network controller software. The TOE controls and restricts the data/information flow from the Local User Interface (LUI), document scanner and document feeder to the network controller software (which covers the information flow to and from the internal network). All data and/or commands received from these interfaces are processed and in most cases transformed by the copy controller before being submitted to the network controller. The network controller further processes the data before sending them to the internal network. The TOE provides separation between the optional FAX processing board and the network interface and therefore prevents an interconnection between the PSTN and the internal network. This separation is realized in software as the network process has no method or API with which to directly connect to the FAX processing board without the use of the copy process as an intermediary. All internal command calls (API) and response messages for both the Network Controller process and the FAX software process are statically defined within the TOE. No user or system administrator is able to change their formats or functionalities. Xerox ColorQube™ 9201/9202/9203 Security Target 82 Copyright 2012 Xerox Corporation, All rights reserved The Fax software runs two independent processes, for sending and receiving job data through the fax card respectively. There is no internal communication between these two processes. The same job data will never be active on both the fax interface and network interface at the same time. For network interface to fax interface (LanFax) jobs, the entire job must be received as an image and buffered in memory before it is sent out through the fax interface. Likewise, for fax interface to network interface (fax forwarding to email) jobs, the entire job must be received from the fax interface and buffered in controller memory before it is transformed by the copy controller process into an email attachment and sent out through the network interface. 7.1.3.Authentication (TSF_ AUT) FIA_ATD.1, FIA_UAU.2, FIA_UAU.7, FIA_UID.2, FIA_USB.1, FMT_SMR.1, FTA_SSL.3 A user must authenticate by entering a username and password prior to being granted access to the Local UI or the Web UI. While the user is typing the password, the TOE obscures17 each character entered. Upon successful authentication, users are granted access based on their role and predefined privileges. Only a system administrator is allowed full access to the TOE including all the system administration functions. Each common user’s access is determined by which function (copy, scan, print, fax etc.) they have permission for. If configured for local authentication the system requires the system administrator to enter a username and password for each user. The system will authenticate the user against an internal database. By default, the Local UI will terminate any session that has been inactive for 60 minutes. By default, the Web UI will terminate any session that has been inactive for 15 minutes. The system administrator can configure both the Local UI and Web UI session timeouts to terminate an inactive session after some other period of time. 7.1.4.Network Identification (TSF_NET_ID) FIA_UAU.2, FIA_UAU.7, FIA_UID.2, FIA_USB.1, FMT_SMR.1, FTA_SSL.3 As an alternative to TSF_AUT, the TOE allows user name and password for a user to be validated by a designated authentication server (a trusted remote IT entity). The user is not required to login to the network; account information entered at Local UI or Web UI of the TOE is authenticated at the server instead of the TOE. The remote authentication services supported by the TOE in the evaluated configuration are: CAC authentication, LDAP v4, Kerberos v5 (Solaris) and Kerberos v5 (Windows 2000/2003). When a user authenticates using the CAC method a PIN number is used instead of a password. The PIN is authenticated by the CAC. The TOE maintains the username from a successful authentication during the context of the job, and this value is entered into the audit log as the user name. 17 The LUI obscures input with the asterisk character. The specific character used to obscure input at the WebUI is browser dependent Xerox ColorQube™ 9201/9202/9203 Security Target 83 Copyright 2012 Xerox Corporation, All rights reserved By default, the Local UI will terminate any session that has been inactive for 60 minutes. By default, the Web UI will terminate any session that has been inactive for 15 minutes. The system administrator can configure both the Local UI and Web UI session timeouts to terminate an inactive session after some other period of time. 7.1.5.Security Audit (TSF_FAU) FAU_GEN.1, FAU_GEN.2, FAU_SAR.1, FAU_SAR.2, FAU_STG.1, FAU_STG.4, FMT_MTD.1 (MGMT1), FPT_STM.1 The TOE generates audit logs that track events/actions (e.g., print/scan/fax job submission) to logged-in users, and each log entry contains a timestamp. The audit logs are only available to TOE administrators and can be downloaded via the web interface for viewing and analysis. The audit log tracks user identification and authentication, session timeout, system administrator actions, and failure of trusted channels. By adopting a policy of regularly downloading and saving the audit logs, users can satisfy the tracking requirements for transmission of data outside of the local environment, as required by such legislation as HIPAA, Sarbanes-Oxley, Gramm- Leach-Bliley, etc. The Web UI presents the only access to the audit log; the audit log is not viewable from the Local UI. The system administrator must be logged in to download the audit log. Application Note: For print and LanFax jobs not submitted from the web UI, the network username associated with the logged in user at the client workstation will be recorded in the audit log. 7.1.6.Cryptographic Operations (TSF_FCS) FCS_CKM.1 (SSL), FCS_CKM.2 (SSL 1), FCS_CKM.2 (SSL 2), FCS_COP.1 (SSL), FCS_CKM.1 (IPSEC), FCS_COP.1 (IPSEC 1), FCS_COP.1 (IPSEC 2), FCS_CKM.1 (SNMP), FCS_COP.1 (SNMP), FCS_CKM.4 The TOE utilizes data encryption (AES, RSA, RC4, DES, TDES) and cryptographic checksum generation and secure hash computation (MD5 and SHA-1), as provided by the OpenSSL cryptographic libraries, to support secure communication between the TOE and remote trusted products. Those packages include provisions for the generation and destruction of cryptographic keys and checksum/hash values and meet the following standards: 3DES – FIPS-42-2, FIPS-74, FIPS-81; MD5 – RFC1321; SHA-1 – FIPS-186, AES-256-FIPS-197 SSLv3 and SNMPv3. 7.1.7.User Data Protection – SSL (TSF_FDP_SSL) FCS_CKM.1 (SSL), FCS_CKM.2 (SSL 1), FCS_CKM.2 (SSL 2), FCS_COP.1 (SSL), FDP_UCT.1 (SSL), FDP_UIT.1 (SSL), FTP_ITC.1, FTP_TRP.1 (SSL), FMT_MTD.1 (KEY) The TOE provides support for SSL through the use of the OpenSSL cryptographic libraries, and allows the TOE to act as either an SSL server or SSL client, depending on the function the TOE is performing. SSL must be enabled before setting up either IPSec, SNMPv3, or before the Xerox ColorQube™ 9201/9202/9203 Security Target 84 Copyright 2012 Xerox Corporation, All rights reserved system administrator can retrieve the audit log. The SSL functionality also permits the TOE to be securely administered from the Web UI, as well as, being used to secure the connection between the TOE and the repository server when utilizing the remote scanning option. As provided for in the SSLv3 standard, the TOE will negotiate with the clients to select the encryption standard to be used for the session, to include operating in backward-compatible modes for clients that do not support SSLv3. The TOE creates and enforces the security policy model, “All communications to the Web server will utilize SSL (HTTPS).” All information that is transmitted between the TOE and a remote trusted product using SSL is protected from both disclosure and modification. The disclosure protection is accomplished by the symmetric encryption of the data being transferred using the DES EDE (aka, Triple DES – defined in FIPS-46-3) cipher or the AES (FIPS-197) cipher, and a per connection key generated as part of the SSLv3 protocol. The modification protection is accomplished by the use of the HMAC (Hashed Message Authentication Code – defined by IETF RFC2104) that is incorporated into the SSLv3 record transfer protocol. Once SSL is enabled on the TOE web services, requests from clients must be received through HTTPS. Additionally, the TOE can act as a web client in the case of workflow scanning. When acting as an SSL client to SSL scan repository, the TOE can validate the remote server’s certificate against a trusted CA; in this configuration, if it cannot validate the identity of the certificate received from the remote server it will not communicate with the scan repository. 7.1.8. User Data Protection – IPSec (TSF_FDP_IPSec) FCS_CKM.1 (IPSEC), FCS_COP.1 (IPSEC 1), FCS_COP.1 (IPSEC 2), FDP_UCT.1 (IPSEC), FDP_UIT.1 (IPSEC), FTP_ITC.1, FTP_TRP.1 (IPSEC), FMT_MTD.1 (KEY) The TOE implements the IPSec SFP to ensure user data protection for all objects, information, and operations handled or performed by the TOE through the lpr and port 9100 network interfaces. Printing clients initiate the establishment of a security association with the MFD. The MFD establishes a security association with the printing client using IPSec. Thereafter, all IP-based traffic to and from this destination will pass through the IPSec tunnel until either end powers down, or resets, after which IPSec must be reestablished. The use of IPSec for communication with a particular destination is based on the presumed address of the printing client. IPSec secures packet flows through two protocols – Encapsulating Security Payload (ESP) and Authentication Header (AH). ESP provides authentication, data confidentiality and message integrity. The ESP extension header provides origin authenticity, integrity, and confidentiality of a packet. AH provides authentication and message integrity, but does not offer confidentiality. The AH guarantees connectionless integrity and data origin authentication of IP datagram. Note: The TOE cannot enforce the IPSec (TSF_FDP_IPSec) security function when it is configured for AppleTalk or IPX networks. 7.1.9.User Data Protection – Disk Encryption (TSF_FDP_UDE) FCS_CKM.1 (UDE), FCS_COP.1 (UDE), FCS_CKM.4 Xerox ColorQube™ 9201/9202/9203 Security Target 85 Copyright 2012 Xerox Corporation, All rights reserved The TOE utilizes data encryption (AES) and cryptographic checksum generation and secure hash computation (SHA-1), as provided by the Loop_AES cryptographic libraries, to support encryption and decryption of designated portions of the hard disk where user files may be stored. Those packages include provisions for the generation and destruction of cryptographic keys. AES data encryption and its associated cryptographic keys are used to encrypt and decrypt the hard drive partition where user jobs are stored or temporarily stored during processing. 7.1.10. User Data Protection – IP Filtering (TSF_FDP_FILTER) FDP_IFC.1 (FILTER), FDP_IFF.1 (FILTER), FMT_MTD.1 (FILTER) The TOE provides the ability for the system administrator to configure a network information flow control policy based on a configurable rule set. The information flow control policy (IPFilter SFP) is defined by the system administrator through specifying a series of rules to “accept,” “deny,” or “drop” packets. These rules include a listing of IP addresses that will be allowed to communicate with the TOE. Additionally rules can be generated specifying filtering options based on port number given in the received packet. Note: The TOE cannot enforce the IP Filtering (TSF_FDP_FILTER) security function when it is configured for IPv6, AppleTalk or IPX networks. 7.1.11. Network Management Security (TSF_NET_MGMT) FCS_CKM.1 (SNMP), FCS_COP.1 (SNMP), FDP_UCT.1 (SNMP), FDP_UIT.1 (SNMP), FMT_MTD.1 (KEY), FTP_TRP.1 (SNMP) The TOE supports SNMPv3 as part of its security solution through the SNMPSec SFP. The SNMPv3 protocol is used to authenticate each SNMP message, as well as provide encryption of the data as described in RFC 3414. As implemented, both an authentication and privacy (encryption) password must be set up both at the device and at the manager. Both passwords must be a minimum of 8 characters. SNMP uses SHA-1 for authentication and single-DES in Cipher Block Chaining mode for encryption. SNMPv3 utilizes the OpenSSL crypto library for the authentication and encryption functions. 7.1.12. Security Management (TSF_FMT) FDP_ACC.1 (USER), FDP_ACC.1 (FUNC), FDP_ACC.1 (MGMT), FDP_ACF.1 (USER), FDP_ACF.1 (FUNC), FDP_ACF.1 (MGMT), FIA_ATD.1, FMT_SMF.1, FMT_MOF.1 (FMT 1), FMT_MOF.1 (FMT 2), FMT_MSA.1 (USER), FMT_MSA.1 (FUNC), FMT_MSA.3 (USER), FMT_MSA.3 (FUNC), FMT_MTD.1 (MGMT1), FMT_MTD.1 (MGMT2), FTP_TST.1 Only authenticated system administrators can enable or disable the Image Overwrite function, change the system administrator password, and invoke an On Demand Image Overwrite operation. While IIO can be disabled, doing so will remove the TOE from its evaluated configuration. Xerox ColorQube™ 9201/9202/9203 Security Target 86 Copyright 2012 Xerox Corporation, All rights reserved Additionally, only authenticated system administrators can assign authorization privileges to users, create user IDs for local authentication, establish a recurrence schedule for On Demand Image Overwrite, enable/disable SSL support, enable/disable and configure IPSec, enable/disable and configure SNMPv3, create/install X.509 certificates, enable/disable and download the audit log, enable/disable and configure (rules) IP filtering, enable/disable disk encryption, enable/disable and configure use of Common Access Cards, configure inactive session timeout settings, verify the integrity of TOE software binary code, and enable/disable and configure 802.1x. Only authenticated users with the necessary privileges are allowed to perform copy, print, scan or fax on the TOE via the Web UI or the LUI. All Users who are authorized to connect to the TOE can submit print or LanFax jobs. All System Administrators are allowed full access to perform copy, print, scan or fax operations on the TOE. Copy has to be performed at the local user interface. A user can only read physical copies of the documents (D.DOC +CPY Read). During job setup, a copy job (D.FUNC +CPY Delete, Modify) or image (D.DOC +CPY Read, Delete) can be read, modified or deleted. Once a job is committed, the job (D.FUNC +CPY Delete, Modify) can only be canceled (deleted) during its execution. Once completed, the job is removed. Print jobs can be submitted remotely via printing protocols (e.g. lpr, port 9100) or from the WebUI using https. Once submitted to the TOE, there is no way for anyone to modify the job (D.FUNC +PRT Modify) or the document (D.DOC +PRT Delete). Each print job has an assigned pass code18 which is only known to the job owner. Only the job owner can release printing of the document (D.DOC +PRT Read) or delete the print job (D.FUNC +PTR Delete) using this pass code at the local user interface before the job is executed on the TOE. The owner may also choose to delete a job (submitted from the Web UI) through Web UI before it is released. A system administrator has the capability for releasing (D.DOC +PRT Read) any print job on the TOE through its authenticated Local UI session. A system administrator also has the capability for deleting (D.FUNC +PRT Delete) any print job on the TOE through its authenticated Local UI or Web UI19 session. Once completed, a print job is removed. Documents can only be scanned at the Local User Interface. During job setup, document image (D.DOC +SCN Read, Delete) may be read or deleted. Once the job is committed, the owner may send the image via email, transfer the image to a remote (SSL scan) repository or keep the image in their private mailbox. (Scan to) Mailboxes are created and owned by individual users. Only the owner is allowed to locate and access the mailbox, and this access to mailboxes is further restricted with a pass code20 which the owner creates and owns. System Administrators have access to all the (scan) mailboxes. (Scan) Images saved in a mailbox (D.DOC +DSR and +SCN 18 A four to ten characters numeric string assigned by the job owner during print job creation. 19 At the Web UI, the the System Administrator can only delete print jobs submitted from the Web UI. 20 An alphanumeric string with length between one to fifty characters owned and managed by the (scan to) mail box owner (creator).

A user with proper access may choose to delete the mailbox together with all images stored inside the mailbox. Faxes can be submitted at the Local User Interface or remotely as LanFax (through the same interfaces as for printing). During job setup, document image (D.DOC +FAXOUT Read, Delete) created may be read or deleted. Once a job (D.FUNC +FAXOUT Delete) is submitted, only a system administrator can delete the Job before it is fully completed, e.g. in the case of delayed send. Access to the received Faxes (D.DOC +FAXIN Read, Delete) is restricted to the system administrators. All received faxes will be stored locally and assigned a (system administrator) predefined pass code. The SA can print or delete secure received faxes by entering the appropriate pass code. Once printed, the faxes are automatically deleted. Alternatively, the system administrator may also choose designate email addresses for receiving fax images. Once the fax job is forwarded as an attachment to an email, the job is automatically deleted. Following recommendations from the user guidance document, an authenticated system administrator can perform various tests to verify the integrity of the TSF. During start up of the TOE after a reboot or power reset, an IIO is performed on U.DOC remaining inside the TOE’s hard drive and the fax flash memory. Upon Hard drive IIO completion, for a randomly picked contiguous block of disk space which is 10% the size of the overall overwritten image, the resulting binary data pattern on the hard drive is compared against the expected results, and any mismatch would be reported. Upon fax flash memory IIO completion, the TOE will attempt to access the files that should be overwritten and report any abnormalities. Also during initial start up, the version number of the software loaded is compared to the expected software version number; any corruption of this data will be reported. During normal operation of the TOE, integrity of the IP filtering table can be verified through manual inspection from the Web UI, by the system administrator.. The System Administrator can also verify the integrity of the TOE software image through the Web UI using a software verification feature.
