The TOE, which conforms to "2600.1, Protection Profile for Hardcopy Devices, Operational Environment A" is designed to operate in an environment such as the one shown below (as excerpted from "2600.1, Protection Profile for Hardcopy Devices, Operational Environment A" clause "1.1 Scope"). This standard is for a Protection Profile for Hardcopy Devices in a restrictive commercial information processing environment in which a relatively high level of document security, operational accountability, and information assurance are required. The typical information processed in this environment is trade secret, mission critical, or subject to legal and regulatory considerations, such as for privacy or governance. This environment is not intended to support life-critical or national security applications. This environment will be known as "Operational Environment A." Figure 1 shows the environment for which the TOE or < Canon imagePRESS C800/C700/C700L/C600 2600.1 model > has been designed, with options included. Since not all of these features may be required, the actual operational environment is expected to differ from what is shown here. Figure 1 The assumed operational environment of the MFP < Canon imagePRESS C800/C700/C700L/C600 > User authentication & FY, lar achonticaticn—> jerver een eat Firewall In Figure 1, the MFP is connected by an internal LAN, to all of the other major components, namely the Mail Server, User Authentication Server, PC, and Firewall. Furthermore, the internal LAN is protected by Firewall from threats from the Internet. To send (via I-Fax or email) a previously scanned document or when receiving a document by I-Fax for example, the MFP connects to the Mail Server. By using a PC with a Web browser’, functions such as printing, storing, or I-Fax can also be executed remotely. However, in order to print from a PC, the appropriate printer driver needs to be installed in the PC. Alternatively, a USB cable could be used to connect the PC directly, and print or store document data from the PC. In this case, some configuration is required initially, in order to protect against data being taken out of the MFP and 2 This evaluation was performed using Microsoft Internet Explorer 8 as the Web browser. Copyright Canon Inc. 2015 Canon stored in a PC or USB device. Date of Issue: 2015/09/28 The TOE also obtains accurate time from the Time server for time synchronization, and supports user authentication through the External Authentication Server. The functions available to the MFP in such an environment are listed below: - Copy function Produces duplicates of the hardcopy document by scanning and printing. - Print function Produces a hardcopy document from its electronic form (contained in the MFP or sent from a PC). - I-Fax RX (receive) function Uses the Internet to receive faxes. Data received by I-fax is not printed immediately; rather it is stored in Memory RX Inbox for processing at a later time. Stored documents can be printed, sent or deleted later. - Universal Send function Scanned document data or electronic documents stored in a Mail Box or in Memory RX Inbox can be transmitted by email or I-fax, or sent to a shared folder on a PC, in TIFF or PDF file format. - Mail Box function Refers to the storage of image files into a Mail Box or in Memory RX Inbox, or to functions that utilize the Mail Box/inbox functionality. - Image files Stored in Mail Box Scanned document data or electronic data specified for storage from a PC, are stored in a Mail Box. - Functions that utilize Mail Box functionality The following functions can be executed on data stored in a Mail Box. - Edit - Print - Send - Delete Copyright Canon Inc. 2015 Canon Date of Issue: 2015/09/28 1.6 Scope of the TOE The TOE conforms to "2600.1, Protection Profile for Hardcopy Devices, Operational Environment A" and is designed to meet the requirements specified therein, as described below.

Copyright Canon Inc. 2015 Canon Date of Issue: 2015/09/28 Output Functionality Enables the TOE to output hardcopy documents. Input Functionality Enables the TOE to input hardcopy documents. The TOE embodies the following security functions. User Authentication Function Performs authentication on the user, to prevent any unauthorized access to the TOE. Two types of user authentication are supported: Internal Authentication wherein authentication takes place internally within the TOE, and External Authentication which uses an external user authentication server. External authentication uses Kerberos’ or LDAP* authentication. Function Use Restriction Function Uses role management to restrict the functions that each authenticated user can use. Job Output Restriction Function This function restricts access to print, cancel and other job operations, to the user that executed the job. Forward Received Jobs Function This function restricts the machine from forwarding received data directly to the LAN. HDD Data Erase Function Function for erasing unnecessary data from the hard disk by overwriting the data, in order to prevent unauthorized use of previously generated image data. HDD Data Encryption Function Because the HDD (alone or together with the HDD Data Encryption & Mirroring Board) could potentially be removed for unauthorized access to its contents, the HDD Data Encryption & Mirroring Board addresses this threat by identifying the MFP at startup, so that it may only be used with the correct MFP. Additionally, all data stored in the HDD are encrypted to protect the confidentiality of the HDD data. LAN Data Protection Function To protect LAN data from IP packet sniffing, IP packets are encrypted using IPSec. Self-Test Function When the machine starts, this function checks to see that the primary security functions are running properly. Audit Log Function Allows auditing of user operations by generating logs stored in the HDD. Stored audit logs are protected and can be viewed. The date/time recorded on the audit log is provided by the TOE. The TOE's date/time information is set by the Management Function, or is set by time synchronization when the accurate time is obtained from the Time Server. Management Function 3 This evaluation was performed using Active Directory Domain Services? as the authentication server software for Kerberos authentication. 4 This evaluation was performed using eDirectory 8.8 SP7 as the authentication server software for LDAP authentication. Copyright Canon Inc. 2015 Canon Consists of user management functions such as user registration and role management, and device management functions which enable proper operation of various security functions, which can only be specified by Administrators.

Defined terms in abbreviated form are set in all caps (for example, "DSR"). In tables that describe Security Objectives rationale, a checkmark ("") placed at the intersection of a row and column indicates that the threat identified in that row is wholly or partially mitigated by the objective in that column. In tables that describe completeness of security requirements, a bold typeface letter "P" placed at the intersection of a row and column indicates that the requirement identified in that row performs a principal fulfillment of the objective indicated in that column. A letter "S" in such an intersection indicates that it performs a supporting fulfillment. In tables that describe the sufficiency of security requirements, a bold typeface requirement name and purpose indicates that the requirement performs a principal fulfillment of the objective in the same row. Requirement names and purposes set in normal typeface indicate that those requirements perform supporting fulfillments. In specifications of Security Functional Requirements (SFRs): Bold typeface indicates the portion of an SFR that has been completed or refined in this Protection Profile, relative to the original SFR definition in Common Criteria Part 2 or an Extended Component Definition.

Some of these drives will not allow data to be written to the drive unless the correct credentials (either the key itself or credentials required to unlock the key stored in a secure area of the drive) are presented. Assuming that this functionality cannot be bypassed, detection of modifications is not a useful function within the TOE and therefore it should be possible to instantiate "no action" in the assignment for the "list of actions" in FPT_CIP_EXP.1.2, arguing that unauthorized modification is prevented by the design of the system.

N/A (no dependencies) 6.4 Security assurance requirements rationale This Protection Profile has been developed for Hardcopy Devices used in restrictive 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 except for removable nonvolatile storage devices, where protection of User and TSF Data are provided when such devices are removed from the TOE environment. 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 3 is appropriate. EAL 3 is augmented with ALC_FLR.2, Flaw reporting procedures. ALC_FLR.2 ensures that instructions and procedures for the reporting and remediation of identified security flaws are in place, and their inclusion is expected by the consumers of this TOE. Copyright Canon Inc. 2015 54 Canon Date of Issue: 2015/09/28 7 TOE Summary specification This section describes the TOE summary specifications. 7.1 User Authentication Function - Supported functional requirements: FIA_UAU.1, FIA_UID.1, FIA_UAU.7, FIA_ATD.1, FIA_USB.1, FIA_AFL.1, FTA_SSL.3(lui), FTA_SSL.3(rui) When the control panel or a remote UI is used to operate the MFP, before permitting such operations, the TOE requires user authentication in order to identify and authenticate valid users. However, the submission of print jobs, and I-fax jobs is always permitted. [FIA_UAU.1, FIA_UID.1] Two methods of user authentication are supported: - External Authentication Authentication is based on user information registered in the authentication server. This may be an Active Directory server that uses Kerberos authentication, or LDAP server that uses LDAP authentication. - Internal Authentication Authentication is based on user information registered in the device. For user authentication, the TOE prompts input of the user name, password, and the login destination. User authentication succeeds only if the user name and password matches the one at the specified destination. For security, note that the password is masked by asterisks in the text field. [FLA_UAU.7] The TOE issues an Access Control Token (ACT) to each user successfully authenticated. The ACT is an object that contains the user's name and role, as well as the access permissions to the application functions that are specified for each user role. [FIA_ATD.1, FIA_USB.1] The TOE provides a lockout function in order to minimize invalid login attempts in Internal Authentication. [FIA_AFL.1] - This function locks out any user that fails to login successfully within the maximum number of failed authentication attempts. A value from 1 to 10 can be specified as the number of attempts before lockout (Initial value: 3). - Any user that is locked out will not be able to login until the lockout time passes. A value from 1 to 60 minutes can be specified as the lockout time (Initial value: 3 minutes). The TOE terminates an interactive session when there is no user activity at the control panel or remote UI lasting for a specified period of time. [FTA_SSL.3(lui), FTA_SSL.3(rui)] - At the control panel, session timeout occurs after a specified period of user inactivity. A value from 10 seconds to 9 minutes can be specified (Initial value: 2 minutes). - At a remote UI, session timeout occurs after 15 minutes of user inactivity.

Any queries, modifications, deletions, and additions to the role contained in the ACT, are performed by U.ADMINISTRATORs only. For Function Use Restriction, the attribute of the Object is the function itself, and is therefore fixed. When the control panel is used, Function Use Restriction Function permits or denies use of functions depending on the settings in "Application Restrictions", which are based on the role contained in the ACT. When a remote UI is used, Function Use Restriction Function permits or denies use of functions based on attribute values associated with the role in the ACT. Only U.ADMINISTRATORS are allowed use of all functions.

Job Output Restriction restricts access to submitted jobs, to the user that executed the job. Copyright Canon Inc. 2015 56 Canon 7.3.1 Job Cancel Date of Issue: 2015/09/28 - Supported functional requirements: FDP_ACC.1(delete-job), FDP_ACF.1(delete-job), FMT_MSA.1(delete-job), FMT_MSA.3(delete-job), FMT_SMF.1 TOE can deletes Print, Copy, and Scan jobs according to following. The user name of these jobs is initialized by username of the user that executed the job. - U.NORMAL is authorized to delete his/her own job. - U.ADMINISTRATOR is authorized to delete all jobs. With the cancellation of the job, the attribute value to be attached to the job is deleted. 7.3.2 In The JOB Access Control - Supported functional requirements: FDP_ACC.1(in-job), | FDP_ACF.1(in-job), FMT_MSA.1(delete-job), FMT_MSA.3(delete-job), FMT_SMF.1 TOE provides the following access control functions for documents in each jobs. User name of these jobs is initialized by username of the user that executed the job. Copy, Scan Jobs - Nobody is authorized to read documents in any copy jobs. Note that, however, the owner of the document and UADMINISTRATOR can conduct priority interrupt printing. - Nobody is authorized to read documents in any scan jobs, except in case of 7.3.3 Temporarily Stored Fax TX Jobs. Temporarily Stored Print Jobs If a print job with a PIN is submitted, the job is temporarily stored in the machine without being output. Additionally, it uses the user name associated with the print job to determine its owner, in order to realize access restriction as described below. For temporarily stored jobs, the following operations are available to U.USERs, only if the user's name matches the user name associated with the desired job. - Print - Change priority for printing - Delete Printing starts when the PIN for the print job is entered from the control panel of the machine. For all temporarily stored jobs, U. ADMINISTRATOR is allowed to execute the following: - Delete Received I-Fax Jobs For documents received by I-fax, the TOE provides the Memory RX Inbox where these jobs may be stored as files, to be output at a later time. Since these are stored in the Memory RX Inbox, access control to this inbox, is equivalent to access control to the stored document data. A seven digit PIN can be assigned to the Memory RX Inbox, to prevent unauthorized access by a user. Copyright Canon Inc. 2015 57 Canon Only U.ADMINISTRATORS are authorized to initialize, set, modify, or delete the PIN on the Memory RX Inbox, which means only U.ADMINISTRATORS are allowed access to the stored document data. The TOE realizes access restriction, by determining the U.ADMINISTRATOR that enters the correct PIN to be the owner of the stored document data, preventing any U.NORMAL from executing print or send operations on the document data. Date of Issue: 2015/09/28 If the control panel is used, U.ADMINISTRATOR is allowed access to the following operations without entering any PIN. - Print - Send - Delete If a remote UI is used, U.ADMINISTRATOR is allowed access to the following operations only by entering the correct PIN. - Print - Send - Delete Document Data Stored in Mail Box For Copy, Scan, or Send jobs, the TOE provides Mail Boxes where these jobs may be stored as document data, to be printed or sent at a later time. Since these are stored in Mail Boxes, access control to Mail Boxes, is equivalent to access control to the stored document data. A seven digit PIN can be assigned to a Mail Box, to help prevent unauthorized access by others. No PIN is required when storing document data in a Mail Box. The TOE realizes access restriction, by determining the U.USER that enters the correct PIN, to be the owner of the stored document data. For document data stored in a Mail Box, the following operations are made available to UNORMAL only by entering the correct PIN. - Print - Change print settings - Preview - Send - Delete If the control panel is used, U.ADMINISTRATOR is allowed access to the following operations without entering any PIN. - Print - Change print settings - Preview - Send - Delete Copyright Canon Inc. 2015 58 Canon Date of Issue: 2015/09/28 If a remote UI is used, U.ADMINISTRATOR is allowed access to the following operations only by entering the correct PIN. - Print - Change print settings - Preview - Send - Delete [Box PIN] For the PIN set on Mail Boxes/Memory RX Inbox, only UADMINISTRATORs assigned the Administrator role are allowed to set or change any PIN. Note however, that U.NORMALS are allowed to change the PIN for the Mail Box they use. 7.3.3 Temporarily Stored Fax TX Jobs - Supported functional requirements: FDP_ACC.1(in-job), FDP_ACF.1(in-job), FDP_ACC.1(delete-job), FDP_ACF.1(delete-job) Send Jobs are Scan jobs. And there are Delayed Send function and Preview function as Temporarily Stored Fax TX Jobs function to store jobs temporarily. Delayed Send When the TOE receives a Fax TX job with transmission time specified, it is first stored temporarily, until sending at the specified time. For temporarily stored Fax TX jobs, the following operations are available to UNNORMALs, only if the user's name matches the user name associated with the desired job. - Change destination For all temporarily stored Fax TX jobs, UADMINISTRATOR is allowed to execute the following: - Change destination Preview When the TOE receives a Fax TX job with Preview setting, it is first stored temporarily and previewed, and later, it is sent. For temporarily stored Fax TX jobs, the following operations are available to U.USERs, only if the user's name matches the user name associated with the desired job. - Preview - Delete Pages - Delete Jobs Copyright Canon Inc. 2015 59 Canon 7.4 Forward Received Jobs Function Date of Issue: 2015/09/28 - Supported functional requirements: FPT_FDI_EXP.1 The design of the TOE prevents received data from being forwarded directly to a server or computer. This function enables the user to restrict forwarding of received jobs to the LAN. 7.5 HDD Data Erase Function - Supported functional requirements: FDP_RIP.1 By overwriting with random data, the TOE permanently erases document data (including temporary image files) in the HDD, to ensure that no trace of the document data remains on the HDD. The user can choose one of the following erasure methods: - Overwrite using the DoD standard - Overwrite with random data three times - Overwrite once with random data - Overwrite once with null data The timing in which data are erased is specified below. - Image files temporarily stored in the HDD as a result of job processing is completely erased during or after processing of the job. - Document data are completely erased from the HDD, immediately after being deleted from Mail Box/Memory RX Inbox. - Residual information that remained unerased due to a sudden power shutdown, is completely erased from the HDD upon startup of the TOE. 7.6 HDD Data Encryption Function - Supported functional requirements: FPT_CIP_EXP.1 The security functions provided by the TOE's "HDD Data Encryption & Mirroring Board" are described below. The encryption/decryption function together with the Device Identification and Authentication function provide confidentiality and integrity protection for user data and TSF data stored in the HDD. 7.6.1 Encryption/Decryption Function - Supported functional requirements: FCS_COP.1(h) To protect the confidentiality and integrity of user data and TSF data stored in the HDD, the TOE performs the following cryptographic operations to encrypt all data stored in the HDD. - Encryption of data written to the HDD. - Decryption of data read out from the HDD. Copyright Canon Inc. 2015 60 Canon The cryptographic algorithm and cryptographic key size are specified below: - AES algorithm (FIPS PUB 197) - 256 bit key length Date of Issue: 2015/09/28 7.6.2 Cryptographic Key Management Function - Supported functional requirements: FCS_CKM.1 The TOE uses the following specifications for generating the cryptographic key that is used by the HDD data encryption function. - Uses a cryptographic key generation algorithm according to FIPS PUB 186-2 - Generates a cryptographic key with 256 bit key length The cryptographic key is managed as follows. - Upon startup, the TOE reads the seed information stored in FlashROM and generates a cryptographic key. - After generating the cryptographic key, the TOE stores the key in RAM. No method is available for acquiring the seed from the encryption board. Note also, that because the cryptographic key is stored in volatile RAM memory, it disappears when power is shut off. 7.6.3 Device Identification and Authentication Function - Supported functional requirements: FPT_PHP.1 The HDD Data Encryption & Mirroring Board identifies the MFP at each startup, and permits access to the HDD only if it is identified as the correct MFP. This function helps prevent unauthorized access to the contents of the HDD, even if the HDD and HDD Data Encryption & Mirroring Board are physically removed and connected to a different MFP. [Registration of the Authentication ID] The HDD Data Encryption & Mirroring Board, when it is initially mounted, acquires the device authentication ID from the MFP device, and stores it in FlashROM. [Procedure for identification and authentication] Upon startup, the HDD Data Encryption & Mirroring board generates a pseudo-random number which it passes to the MFP device as a random number to a challenge. The MFP device makes a computation using its device authentication ID and the received random number, and passes the resulting hash value (SHA-1) to the encryption board. The HDD Data Encryption & Mirroring Board performs the same computation in order to verify the response. Access to the HDD is denied, unless the HDD Data Encryption & Mirroring Board confirms successfully that it is mounted on the correct MFP device.

The date/time is provided by the TOE. The TOE's date/time information is set by the Management Function, or is set by time synchronization when the accurate time is obtained from the Time Server. - Date/Time, User Name, Event Type, Outcome (Success/Failed) Other log events may have additional items as described below. - Job type (job completion) - Name of the user that failed authentication (authentication failure) Also, export of audit logs can be performed from a remote UI, in order to read out log records, although use of this function is restricted to UADMINISTRATORs only. Users other than UADMINISTRATOR are not allowed to export audit logs when logged in to the TOE from a remote UI. When accessing the TOE from a remote UI, another capability restricted to UUADMINISTRATORs only is the deletion of log records from the [Deleting Collected Logs] menu. Users other than U.ADMINISTRATOR are not allowed access to this capability when logged in to the TOE from a remote UI, thus preventing unauthorized alterations from occurring. A maximum of 20,000 audit records can be maintained. Once this becomes full, the oldest audit record is overwritten with the newest. 7.10 Management Functions 7.10.1 User Management Function - Supported functional requirements: FIA_SOS.1 , FMT MTD.l(user-mgt) , FMT_MSA.I(exec-job) FMT_MSA.1(delete-job), FMT_MSA.3(delete-job) ,FMT_SMR.I, FMT_SMF.1 In the TOE, only U:ADMINISTRATORs assigned the Administrator role can set, change, or delete user, role, and access restriction information and box PINs. General users or U.NORMAL, can only change their own passwords and the PIN for the Mail Box they use. [Setting/Changing/Deleting User, Role, and Access Restriction Information] New users are registered by setting the user name and password, and assigning a role to the user. Registered Copyright Canon Inc. 2015 63 Canon user information can be modified by changing the password or the assigned role, or the user's registration can be deleted altogether. User specified passwords are checked to see that they are consistent with the password policy. Date of Issue: 2015/09/28 Five roles exist, which are called "Base Roles": Administrator, Power User, General User, Limited User, and Guest User. To create a new "Custom Role" different than these, any one of four base roles excluding Guest User, is used as a template for the new role, which can then be registered. The Administrator role is a role whose base role is "Administrator", and has administrative privileges. The initial value for "Base Role" can be changed to any one of four base roles except Guest User. The access restriction information that determines whether use of certain functions is permitted or denied, is specified by the "Application Restrictions" setting, which depends on what role is assigned. Although the initial value for "Application Restrictions" is fixed for base roles, the initial value of "Application Restrictions" can be changed for custom roles. [Types of Users] There are two types of users: U.ADMINISTRATOR and U.NORMAL. - U.ADMINISTRATOR User assigned the Administrator role and has administrative privileges. - U.NORMAL General user assigned a role other than Guest User role or Administrator role. 7.10.2 Device Management Function - Supported functional requirements: FMT_MTD.1(device-mgt), FMT_SMF.1, FMT_SMF.1 To provide effective enforcement of security functions, the TOE allows only UADMINISTRATORs to set the device management settings in Table 27.
