The functions that are allowed, but not required in any particular conforming Security Target or Protection Profile, are listed in Table 2-1. Table 2-1 SFR Package functions 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 2.3.3 SFR Package attributes When a function is performing processing, storage, or transmission of data, the identity of the function is associated with that particular data as a security attribute. This attribute in the TOE model makes it possible to distinguish differences in Security Functional Requirements that depend on the function being performed. The attributes that are allowed, but not required in any particular conforming Security Target or Protection Profile, are listed in Table 2-2. Table 2-2 SFR Package attributes Designation Definition +PRT Indicates data that are associated with a print job. +SCN Indicates data that are associated with a scan job. +CPY Indicates data that are associated with a copy job. +FAXIN Indicates data that are associated with an inbound (received) fax job. +FAXOUT Indicates data that are associated with an outbound (sent) fax job. +DSR Indicates data that are associated with a document storage and retrieval job. +SMI Indicates data that are transmitted or received over a shared-medium interface. 2.4 PP Conformance rationale 2.4.1 Conformance Claim with TOE type of the PP bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 26 / 83 The product type that the PP intends is Hard Copy Device (Hereinafter referred to as "HCD"). The HCD is a product used for converting hard copy document to digital form (SCAN) or for converting digital document to hard copy form (PRINT) or for transmitting hard copy document through the telephone line (FAX), or for generating a copy of hard copy document (COPY). The HCD is implemented by many different configurations depending on objectives, and in order to extend a function, there are some which have added hard disk drive, other non-volatile storage system or document server function, etc. This TOE type is the MFP. The MFP have devices that the HCD has including additional devices and functions that the HCD has are installed. Therefore, this TOE type is consistent with the PP's TOE type. 2.4.2 Conformance Claim with Security Problem and Security Objectives of the PP This ST adds each of OSP and Objective along with security problem of the PP, but this is consistent with the PP. The rationale is described below. Added OSP in ST is P.HDD.CRYPTO. This requests to encrypt the data recorded in HDD. This does not give restriction relating to operational environment, but restricts the TOE. Also, the added Objective (O.HDD.CRYPTO) in the ST is corresponding to added OSP and this also does not give restriction relating to operational environment, but restricts the TOE. Therefore, the ST imposes restriction on the TOE more than the PP and imposes on TOE’s operational environment equivalent to the PP. This satisfies the conditions that are equivalent or more restrictive to the PP. 2.4.3 Conformance Claim with Security requirement of the PP The SFRs of this TOE consist of Common Security Functional Requirements, 2600.1-PRT, 2600.1-SCN, 2600.1-CPY, 2600.1-FAX, 2600.1-DSR and 2600.1-SMI. Common Security Functional Requirements are mandatory SFRs specified by the PP and 2600.1-PRT, 2600.1-SCN, 2600.1-CPY, 2600.1-FAX, 2600.1-DSR, and 2600.1-SMI are selected from SFR Packages specified by the PP. Security requirements of this ST include the part that is added and fleshed out to security requirements of the PP, but this is consistent with the PP. The following describes the part that is added and fleshed out, and the rationale that those are consistent with the PP. Common Access Control SFP The PP defines access control relating to Delete and Read of D.DOC that has attributes of +FAXIN, and Modify and Delete of D.FUNC, but anybody can cancel FAX communication that the TOE is receiving, without restriction. And so, D.DOC and D.FUNC under receiving are deleted. However, this is not the process to intend to Delete of D.DOC and D.FUNC and this is the Delete associated with the cancel of transmission. Other than it is recorded as log, this does not undermine the requirement of the PP, since this is saved in the user box after receiving and protected by becoming the object of DSR Access Control SFP. Also, it cannot Modify D.FUNC of FAX under receiving. This is the access control more restricted than PP. The TOE defines access control relating to Modify of D.DOC that has attributes of +SCN and +FAXOUT. This is not defined in the PP, but this restricts deletion with page unit to U.NORMAL that is the owner of D.DOC. Access control relating to Delete is defined in the bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 27 / 83 PP, but the TOE provides Delete function with page unit in addition to same access control with the PP. However, that operation is restricted to owner of D.DOC and this does not relax the restriction of access control SFP of the PP. Addition of FAU_SAR.1, FAU_SAR.2, FAU_STG.1, FAU_STG.4(1), FAU_STG.4(2) This TOE adds FAU_SAR.1, FAU_SAR.2, FAU_STG.1, FAU_STG.4(1) and FAU_STG.4(2) in accordance with the PP APPLICATION NOTE5 and PP APPLICATION NOTE7 to maintain and manage the audit log. Addition of FCS_CKM.1, FCS_COP.1, FIA_SOS.1(2) This TOE adds O.HDD.CRYPTO as Objectives, and with that, FCS_CKM.1, FCS_COP.1 and FIA_SOS.1(2) are added, but this does not mean to change the contents of security requirements specified by the PP. Conformance of FDP_ACF.1(a) FDP_ACF.1 (a) of the PP requires access control SFP that permits access only to his/her own documents and to his/her own function data. This TOE performs access control based on the security attributes of D.DOC and D.FUNC, and other than that, D.DOC and D.FUNC that are saved in the TOE is stored in the user box under protected directory and those are protected by the access control of user box. User box is protected by password, and the TOE positions user who manages user box password as the owner of D.DOC and D.FUNC in the user box and it performs access control. This will protect against unauthorized disclosure and alteration of D.DOC and D.FUNC. FDP_ACF.1 (a) of this ST requires this access control SFP. Therefore, FDP_ACF.1 (a) of this ST satisfies FDP_ACF.1 (a) of the PP. Addition of FIA_AFL.1, FIA_SOS.1(1), FIA_UAU.6, FIA_UAU.7 Machine authentication is the function that this TOE implements. In accordance with the PP APPLICATION NOTE 36, FIA_AFL.1, FIA_SOS.1(1), FIA_UAU.6 and FIA_UAU.7 are added. Addition of FMT_MOF.1 The TOE has the function to enable and disable Enhanced Security Setting. The TOE requires operating in the state of enabled Enhanced Security Setting by the guidance, and FMT_MOF.1 restricts the change of Enhanced Security Setting only to U.ADMINISTRATOR and prevents from unauthorized change of Enhanced Security setting. This is not the change of content of security requirement specified by the PP. FMT_MOF.1 restricts the management function about FTP_ITC.1 and the management of User Authentication function only to U.ADMINISTRATOR and prevents from unauthorized execution of management function. This is not the change of content of security requirement specified by the PP. The management of behavior of “HDD data overwrite deletion function” manages the bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 28 / 83 behavior of the overwrite deletion function to protect the residual information and this is not the change of content of security requirement specified by the PP. The management of behavior of audit function manages the operation at the time of audit log full and this is not the change of content of security requirement specified by the PP. Relation between FMT_MSA.1(a), FMT_MSA.1(b) and Objectives The relationship between these functional requirements and objectives are different from PP, but this does not change the contents of security requirements specified by the PP. This is because disclosure and alteration of security attribute based on TSF data, such as attribute of user box, produces the same result with disclosure and alteration of TSF data itself and management of a security attribute has the same purpose and effect as protection of TSF data. D.DOC in USB flash drive The TOE assigns login user from operation panel as the owner of D.DOC in the concerned USB flash drive when USB flash drive is installed in the TOE, and performs access control. This will protect D.DOC against unauthorized disclosure and alteration and FDP_ACF.1(a) of this ST requires this access control SFP. Therefore, FDP_ACF.1(a) of this ST satisfies FDP_ACF.1(a) of the PP. 3 Security Problem Definition 3.1 Threats agents 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 are not authorized. d) Persons who unintentionally cause a software malfunction that may expose the TOE to unanticipated threats. The threats and policies defined in this Protection Profile address the threats posed by these threat agents. bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 29 / 83 3.2 Threats to TOE Assets This section describes threats to assets described in clause in 1.4.6.

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. Table 3-3 Organizational Security Policies for the TOE Name Definition P.USER.AUTHORIZATION To preserve operational accountability and security, Users will be authorized to use the TOE only as permitted by the TOE Owner. 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.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. P.INTERFACE.MANAGEMENT To prevent unauthorized use of the external interfaces of the TOE, operation of those interfaces will be controlled by the TOE and its IT environment. P.HDD.CRYPTO The Data stored in an HDD must be encrypted to improve the secrecy. 3.4 Assumptions The Security Objectives and Security Functional Requirements defined in subsequent sections bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 30 / 83 of this Protection Profile are based on the condition that all of the assumptions described in this section are satisfied.

These extended components are defined in the Protection Profile but are used in SFR Packages and, therefore, are employed only in TOEs whose STs conform to those SFR Packages. 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 these data are 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. Management: FPT_FDI_EXP.1 The following actions could be considered for the management functions in FMT: Definition of the role(s) that are allowed to perform the management activities Management of the conditions under which direct forwarding can be allowed by an FPT_FDI_EXP.1 Restricted forwarding of data to external interfaces 1 bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 36 / 83 administrative role Revocation of such an allowance Audit: FPT_FDI_EXP.1 The following actions should be auditable if FAU_GEN Security Audit Data Generation is included in the PP/ST: 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 are 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 Protection Profile, 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 either too implementation-specific for a Protection Profile or 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 it could therefore be placed in either the FDP or the 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 led the authors to define a new family with just one member.

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. bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 70 / 83 7 TOE Summary specification The list of the TOE security functions led from the TOE security functional requirements is shown in Table 7-1.

The TOE stores the audit log in the HDD of the TOE, but the following process is performed when the storage area became full. (1)When “Restriction of overwriting” is set, the acceptance of jobs is suspended. (2)When “Permission of overwriting” is set, the oldest stored audit log is overwritten. The settings of (1) and (2) are performed by U.ADMINISTRATOR. 7.1.4Trusted time stamp function - Corresponding functional requirements: FPT_STM.1, FMT_MTD.1 The TOE has clock function and provides U.ADMINISTRATOR with the function to modify TOE time. Only U.ADMINISTRATOR can change the time information by FMT_MTD.1. The TOE issues time stamp of clock function at the time of audit log generation and records as the audit log. 7.2 F.HDD_ENCRYPTION (HDD Encryption function) - Corresponding functional requirements: FCS_CKM.1, FCS_COP.1, FIA_SOS.1(2) The TOE performs encryption to protect data stored in HDD against unauthorized disclosure. Used encryption key and algorithm are as follows. (1) Encryption Key Encryption key is generated by Konica Minolta HDD encryption key generation algorism that Konica Minolta encryption specification standard defines. (Encryption key length is 256 bit.) Unique encryption key for each TOE is generated by generating it based on the encryption passphrase set by U.ADMINISTRATOR. Only encryption passphrase that satisfies the following qualities is accepted. bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 72 / 83  Number of characters: 20 characters  Character type: possible to choose from 83 or more characters  Rule: Do not compose by only one and the same character.

Read document can be printed and can be saved in the user box. This function can be performed only on the operation panel and cannot be operated through the network such as interface of Web. 7.5 F.RIP (Residual information deletion function) 7.5.1 Temporary Data Deletion Function - Corresponding functional requirement: FDP_RIP.1 The TOE prevents to reuse the residual information by overwriting and deleting the deleted document, the temporary document or its parts in HDD. This function is performed at the following timing. (1) When a job such as print or scan is completed or suspended. Delete the temporary document or its parts which is generated during job execution. (2) When the deleting operation is performing. Delete the specified document. (3) When the residual information exists at the time of turning on the power. When the power is turned off during deletion of (1) or (2) and the deletion was not completed with the residual information, this deletes them at the time of the power ON. U.ADMINISTRATOR sets the overwriting data and the frequency of overwriting, by the operation setting function of the HDD data overwrite deletion function. The possible settings and its details are as follows. Table 7-6 Operation Settings of Overwrite Deletion function of Temporary data Setting Contents (Overwritten data type and its order) Mode:1 Overwrite once with 0x00 Mode:2 Overwrite with 0x00, 0xFF, 0x61 in this order and Verify the result. bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 76 / 83 7.5.2 Data Complete Deletion Function - Corresponding functional requirements: FDP_RIP.1, FDP_ACF.1(a) U.ADMINISTRATOR can perform overwriting and deleting to the data area including image data in HDD. This deletes document in HDD and prevents to reuse the residual information. U.ADMINISTRATOR sets the overwriting data and the frequency of overwriting, by the operation setting function of the HDD data overwrite deletion function. The possible settings and its details are as follows. Table 7-7 Operation settings of Data Complete Deletion Function Method Overwritten data type and their order Mode:1 0x00 Mode:2 Random numbers ⇒ Random numbers ⇒ 0x00 Mode:3 0x00 ⇒ 0xFF ⇒ Random numbers ⇒ Verification Mode:4 Random numbers ⇒ 0x00 ⇒ 0xFF Mode:5 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF Mode:6 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF ⇒ Random numbers Mode:7 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF ⇒ 0xAA Mode:8 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF ⇒ 0x00 ⇒ 0xFF ⇒ 0xAA ⇒ Verification 7.6 F.I&A (Identification and authentication function) - Corresponding functional requirements: FIA_AFL.1, FIA_ATD.1, FIA_SOS.1(1), FIA_UAU.1, FIA_UAU.6, FIA_UAU.7, FIA_UID.1, FIA_USB.1, FTA_SSL.3 The TOE verifies that person who tries to use the TOE is the authorized user by using the identification and authentication function obtained from the user, and permits the use of the TOE only to the person who was determined as the authorized user. Identification and authentication function has the machine authentication method that the TOE itself identifies and authenticates, and the external server authentication method that uses external authentication server. Table 7-8 Authentication method Authentication method Possible operations before success of identification and authentication SFR Machine Authentication External Server Authentication Confirmation of suspension state of User use Confirmation of suspension state of Account use FAX RX Confirmation of TOE State and Setting of display, etc. FIA_UID.1 FIA_UAU.1 * The setting of authentication method is performed by U.ADMINISTRATOR. Both Machine authentication and External sever authentication are activated at the same time. When both of them are activated, U.ADMINISTRATOR sets which methods are used for each user. User, who U.ADMINISTRATOR sets both authentication methods available, selects by oneself at the time of bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 77 / 83 authentication. The TOE also displays “*” for input password. FIA_UAU.7 This requires re-authentication when login password is changed. FIA_UAU.6 When identification and authentication are successful, User ID, Group ID and Allocation Role are combined to the process that acts as the appropriate user. FIA_ATD.1, FIA_USB.1 Moreover, the TOE prevents from setting the low strength password by restricting for satisfying the following qualities in the passwords used for authentication. Table 7-9 Password and Quality Objective Condition SFR Login Password The TOE accepts only the password that satisfies the following. -Number of characters : 8 or more characters -Character type : possible to choose from 94 or more characters -Rule : (1) Do not compose by only one and the same character. (2) Do not set the same password as the current setting after change. FIA_SOS.1(1) Account Password When the authentication failed, the TOE performs the following process. Table 7-10 Process at the time of authentication failure Objective Process SFR Authentication failure by login password Authentication is suspended when number of continuous authentication failure reached the value that U.ADMINISTRATOR set. Authentication is also suspended even if the number of continuous authentication failure exceeds the setting value because of the change of setting value by U.ADMINISTRATOR. When the authentication of administrator is suspended, it is released by performing boot process of the TOE and passing the time set in the release time setting of operation prohibition for administrator authentication from boot process. In other cases, it is released by performing deletion function of number of authentication failure by administrator. FIA_AFL.1 When the identified and authenticated user does not operate for a certain period of time, the session is terminated. The details are as follows. FTA_SSL.3 Table 7-11 Termination of interactive session Objective Session termination Others Operation panel When it passes for the time determined by auto reset time, after processing of last Auto reset time is set in the factory and administrator can change it. bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 78 / 83 operation was completed.

Data Administrator When it passes for 60 minutes, after processing of last operation was completed.* Time is fixed Printer driver Fax There is no interactive session since accept of the request is the start and the completion of process is end. Identification and authentication is performed in each acceptance except Fax RX. *This is the time considered the process that takes time such as downloading the registered information. 7.7 F.SEPARATE_EX_INTERFACE (External interface separation function) - Corresponding functional requirement: FPT_FDI_EXP.1 The TOE prevents the access from telephone line by limiting the input information from telephone line only to FAX RX and Remote Access function, and prohibits the direct transfer of received fax. Moreover, it is a structure which cannot be transfer the input from external interface including USB interface to Shared-medium Interface as it is. 7.8 F.SELF_TEST (Self-test function) - Corresponding functional requirement: FPT_TST.1 The TOE contains the data for verification and decrypts it by using encryption passphrase when the power is ON. This verifies the integrity of encryption passphrase by confirming that the data for verification was decrypted correctly. And then, this provides HDD encryption function and the function to verify the normal operation of TSF executable code. Moreover, the TOE verifies the integrity of TSF executable code by calculating hash value of control software when the power is ON and checking whether it corresponds to the recorded value or not. If the loss of completeness was detected in the integrity verification of encryption passphrase and control software, the TOE displays the alert on the operation panel and does not accept the operation. 7.9 F.MANAGE (Security management function） bizhub C754e/bizhub C654e/ ineo+ 754e/ineo+ 654e Security Target Copyright ©2013-2014 KONICA MINOLTA, INC., All Rights Reserved 79 / 83 - Corresponding functional requirements: FIA_SOS.1(1), FMT_MOF.1, FMT_MSA.1(a), FMT_MSA.1(b), FMT_MSA.3(a), FMT_MSA.3(b), FMT_MTD.1, FMT_SMF.1, FMT_SMR.1 The TOE provides the following management functions.

If object is deleted, the attribute that is given to that object is also deleted. About the movement, for example the movement from the personal user box to the group user box changes Box Type and the attribute into Box Group ID from Box User ID. The access to the object in the user box and the save (create) to the destination depends on "7.3 F.ACCESS_DOC (Accumulated documents access control function." Movement can be executed only between the accumulated user boxes. Note that the operations of BOX PASSWORD and DOC PASSWORD that are the subject security attributes, and the operations of User ID, Box Type, and DOC PASSWORD that are the object security attributes, are not available.
