The TOE running on one of the supported specified hardware models constitutes a Multi-Function Printer (MFP). Firmware version: ATL. 030.079CC: CX725 and XC4140 Conformance is claimed to PP Identification: 2600.1, Protection Profile for Hardcopy Devices, Operational Environment A, version 1.0, dated January 2009 with the includ- ing packages:  PRT, SFR Package for Print Functions,  SCN, SFR Package for Scan Functions,  CPY, SFR Package for Copy Functions,  FAX, SFR Package for Fax Functions and  SMI, SFR Package for Shared-medium Interface Functions The Security Target (ST) claims demonstrable conformance to the Security Problem Definition (APE_SPD), Security Objectives (APE_OBJ), Extended Components Def- initions (APE_ECD), and the Common Security Functional Requirements (APE_REQ) of the referenced PP. The TOE performs the functions F.PRT, F.SCN, F.CPY, F.FAX, and F.SMI as de- fined in the referenced PP and claims demonstrable conformance to the augmented SFR packages defined for each of these functions. There are five assumptions made in the ST regarding the secure usage and environ- ment of the MFD. The TOE rely on these being met in order to be able to counter the six threats, and to fulfill the four organizational security policy (OSP) in the ST. The assumptions, the threats and the organizational security policies are described in chap- ter 4 Assumptions and Clarification of Scope. The evaluation has been performed by Combitech AB and EWA-Canada. The evalua- tion was conducted in accordance with the requirements of Common Criteria, version 3.1, release 4, and the Common Methodology for IT security Evaluation, version 3.1, release 4.

Below is a short description of each of them. For more information, see Security Target [ST] Audit Generation The TOE generates audit event records for security-relevant events and transmits them to a remote IT system using the syslog protocol. Identification and Authentication When a touch panel or web session is initiated, the user is implicitly assumed to be the Guest (default) user. Per the evaluated configuration, the permissions for this user must be configured such that no access to TSF data or functions is allowed. Therefore, the user must successfully log in as a different user before any TSF data or functions may be accessed. The TOE supports I&A with a per-user selection of Username/Password Accounts (processed by the TOE) or integration with an external LDAP server (in the operation- al environment). Smart Card authentication may also be specified for users of the touch panel. Access Control Access controls configured for functions (e.g. fax usage) and menu access are en- forced by the TOE. Management Through web browser and touch panel sessions, authorized administrators may con- figure access controls and perform other TOE management functions. Fax Separation The TOE ensures that only fax traffic is sent or received via the attached phone line. Incoming traffic is processed as fax data only; no management access or other data ac- cess is permitted. In the evaluated configuration, the only source for outgoing faxes is the scanner. D.DOC Wiping In the evaluated configuration, the TOE automatically overwrites RAM used to store user data as soon as the buffer is released. Secure Communication The TOE protects the confidentiality and integrity of all information exchanged over the attached network by using IPSec with ESP for all network communication. Cryp- tographic keys may be generated by the TOE or pre-shared keys may be entered by the administrator. Self Test During initial start-up, the TOE performs self tests on its cryptographic components and the integrity of the configuration data. Swedish Certification Body for IT Security Certification Report Lexmark MFD NoHD 16FMV1483-18:1 1.0 2017-03-09 CB-015 7 (22) 4 Assumptions and Clarification of Scope 4.1 Usage Assumptions The following assumption about the usage are made: A.ADMIN.TRAINING Administrators are aware of the security policies and proce- dures of their organization, are trained and competent to follow the manufacturer’s guidance and documentation, and correctly configure and operate the TOE in accord- ance with those policies and procedures. A.ADMIN.TRUST Administrators do not use their privileged access rights for mali- cious purposes. 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 proce- dures. 4.2 Environmental Assumptions The following assumption about the environment are made: 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.IPSEC IPSec with ESP is used between the TOE and all remote IT systems with which it communicates over the network using IPv4 and/or IPv6. 4.3 Clarification of Scope Four categories of threat agents are defined:  Persons who are not permitted to use the TOE who may attempt to use the TOE.  Persons who are authorized to use the TOE who may attempt to use TOE func- tions for which they are not authorized.  Persons who are authorized to use the TOE who may attempt to access data in ways for which they are not authorized.  Persons who unintentionally cause a software malfunction that may expose the TOE to unanticipated threats. The identified threats against the TOE are listed below:  T.CONF.ALT TSF Confidential Data may be altered by unauthorized persons  T.CONF.DIS TSF Confidential Data may be disclosed to unauthorized persons  T.DOC.ALT User Document Data may be altered by unauthorized persons  T.DOC.DIS User Document Data may be disclosed to unauthorized persons  T.FUNC.ALT User Function Data may be altered by unauthorized persons  T.PROT.ALT TSF Protected Data may be altered by unauthorized persons Four Organisational Security Policies are defined.  P.AUDIT.LOGGING To preserve operational accountability and security, records that provide an audit trail of TOE use and security-relevant events will be created, maintained, and protected from unauthorized disclosure or alteration, and will be reviewed by authorized personnel Swedish Certification Body for IT Security Certification Report Lexmark MFD NoHD 16FMV1483-18:1 1.0 2017-03-09 CB-015 8 (22)  P.INTERFACE.MANAGEMENT To prevent unauthorized use of the external in- terfaces of the TOE, operation of those interfaces will be controlled by the TOE and its IT environment.  P.SOFTWARE.VERIFICATION To detect corruption of the executable code in the TSF, procedures will exist to self-verify executable code in the TSF.  P.USER.AUTHORIZATION To preserve operational accountability and security, Users will be authorized to use the TOE only as permitted by the TOE Owner. Nine assumptions on the operational environment are defined, none of them are to be characterized as unusual.

[PP]. The TOE is comprised of the following subsystems: Operating System The Operating System subsystem provides standard operating system services such as file system, process management, timers and memory management. The memory management functionality zeroizes buffers in memory upon deallocation. The Operating System subsystem executes a series of self-tests of the MFP upon each start-up of the system. This subsystem also maintains the system time, which is used to insert timestamps into audit records when they are generated. GUI Manager The GUI Manager subsystem handles all interactions with local users via the touch screen and keypad. This subsystem retrieves (from the Object Store subsystem) and displays the appropriate information on the touch screen and processes input from the touch screen and keypad. When configuration changes are made, the updated infor- mation is sent to the Object Store subsystem to be saved and acted on. User Authentication The User Authentication subsystem handles all validation of user credentials and au- thorizations, whether the validation is performed locally or remotely. When creden- tials or authorization checks are received from the GUI Manager or Web Server sub- systems, User Authentication retrieves information from Object Store to determine if local, remote, or PKI validation should be performed. Swedish Certification Body for IT Security Certification Report Lexmark MFD NoHD 16FMV1483-18:1 1.0 2017-03-09 CB-015 10 (22) Object Store The Object Store subsystem is responsible for managing the storage of configuration parameters, forwarding audit records between the generating subsystem and the Audit subsystem, and forwarding user jobs between the receiving subsystem and the destina- tion subsystem. This subsystem also maintains a list of pending user jobs. Audit The Audit subsystem is responsible for formatting audit information into the standard Syslog format, inserting a timestamp, and forwarding the audit records to the config- ured Syslog server. If NTP is configured, this subsystem also interacts with the con- figured NTP server(s) to maintain the system time. Network Interface The Network Interface subsystem is responsible for all interactions with the Network Interface Card and provides all the processing of network protocol layers that are common to multiple software subsystems (e.g. TCP, IP, IPSec). This subsystem inter- acts with remote IT systems via the network protocols. Since cryptography is required for several of the network protocols to establish trusted channels, this subsystem par- ticipates in key management functions and invokes the Crypto Library subsystem to perform cryptographic operations. All communication with remote IT systems is re- quired to use IPSec. Print The Print subsystem processes received print jobs from the network interface, scanner and fax line (via the Object Store subsystem). Received network print jobs are queued to be deleted after the print job expiration timeout if they do not contain a PJL SET USERNAME statement. Audit information is generated as jobs are received, indicat- ing the job is created. The user jobs are converted to raster images and queued for printing. The list of user jobs waiting to be printed is communicated to the Object Store subsystem. Audit information is generated as jobs are completed. Scan Manager The Scan Manager subsystem is responsible for controlling the operation of the scan- ner hardware and formatting the scanned images into an appropriate format. This sub- system invokes the Operating System subsystem to save the user data in memory. The format may be an email message with an attachment for scan-to-email operations or scan-to-fax operations (when fax server is configured), or raster image for copy opera- tions or scan-to-fax operations (when analog fax is configured). The currently logged in user on the touch screen is the user associated with the job. Once formatted, the user job is sent to the Object Store subsystem for delivery to the destination subsystem. Email The Email subsystem is responsible for forwarding user jobs to a remote IT system via SMTP. In the evaluated configuration, the user jobs may have originated from a scan- to-email operation or a scan-to-fax operation with the fax server configured. The Op- erating System subsystem is invoked to open the file containing the user data. When the user job has been forwarded, the Operating System subsystem is invoked to delete the file containing the user data and zeroize the memory in which the data was stored. Audit information is generated upon job completion and forwarded to the Audit sub- system via the Object Store subsystem. Swedish Certification Body for IT Security Certification Report Lexmark MFD NoHD 16FMV1483-18:1 1.0 2017-03-09 CB-015 11 (22) Web Server The Web Server subsystem is responsible for providing user access to TOE functions from remote IT systems via browser sessions (Remote Management Access (RMA)). This subsystem retrieves (from the Object Store subsystem) and presents the appropri- ate information for display. When configuration changes are made, the updated infor- mation is sent to the Object Store subsystem to be saved and acted on. Fax The Fax subsystem is responsible for controlling the operation of the fax modem hardware. For incoming faxes, this subsystem invokes the Operating System subsys- tem to save the user data as a raster image in memory. Unprocessed data is never ac- cepted by this subsystem and the evaluated configuration does not permit unprocessed data received via the fax line to be forwarded out the Network Interface Card. The touch screen user that releases the held faxes is the user associated with the job. Once complete, the user job is sent to the Object Store subsystem for delivery to the Print subsystem. Crypto Library The Crypto Library subsystem provides cryptographic algorithm support used by other subsystems to perform cryptographic operations. The operations supported include en- cryption, decryption, hashing, message authentication coding, digital signatures and random number generation.

The developer’s testing covers the security functional behavior of all TSFIs and SFRs as well as the interactions of the subsys- tems. The developer’s testing comprised both firmware and all printer models. Independent Evaluator Tests The evaluator’s independent tests were chosen to complement the developer’s manual tests in covering as much of the security functional behavior of the TSFIs and SFRs. The evaluator repeated developer’s test cases and performed individual and penetra- tion tests. The tests included:  TOE Installation  Identification and Authentication  Access Control and Management  Trusted Channel  Repetition of Developer’s Testing The evaluator used a similar test configuration as the developer consisting of:  TOE: CX725 without Smart Card reader  Workstation: Windows client used to send print jobs to the TOE, open browser sessions to manage the TOE, and to exchange email with the Email Server.  Primary Domain Controller: Windows server providing Active Directory, DNS, Kerberos, GSSAPI, PKI and NTP services  Email Server: SMTP server capable of receiving email from the TOE and for- warding it to a user on Workstation  Syslog Server: Capable of receiving and displaying Syslog messages from the TOE  Network Monitor: Used to display and analyse network traffic  Fax: Analog fax machine  IP Network  Phone network The tests were run manually from the MFP’s touch screen, the Embedded Web Server, and the workstation. The actual results of all test cases were consistent with the ex- pected test results and all tests were judged to pass. Penetration Tests The following types of vulnerability tests were performed:  Port scan  Vulnerability scan  PNG fuzzing  LDAP+GSSAPI authentication down negotiation  IPSec down negotiation  IPSec scanning Swedish Certification Body for IT Security Certification Report Lexmark MFD NoHD 16FMV1483-18:1 1.0 2017-03-09 CB-015 14 (22) Port scans were run after installation and configuration had been done according the guidance documentation. The purpose was to check that no unexpected ports were opened unfiltered and no unexpected services available. The Nmap (www.nmap.org) port scan tool was used. Four different modes were used: TCP Connect, TCP SYN, UDP, and IP protocol scans. All possible 65535 ports were scanned for TCP/UDP. A scanning tool for network vulnerabilities were run. No high severity issues were found. A fuzzing tool were used to randomly change the content of a PNG image. The fuzzed images were sent to the MFP for printing. It was verified that all traffic to and from the Primary Domain Controller was using IPSec in ESP mode. It was also verified that no down negotiating to weaker algo- rithms than specified for the trusted channel, [ST] table 18, is possible. The IPSec protocol were scanned using an IKE/IPSec scanning tool to reveal unspeci- fied primitives, key lengths, etc. Search in public sources did not revealed any exploitable or residual vulnerabilities in the TOE including its third party software libraries. All penetration testing had negative outcome, i.e. no vulnerabilities were found.
