Key operator makes settings described in Table 1-1 after being identified and authenticated as key operator. Table 1-1: Setting Data Item number Setting data 1 Setting for HDD overwrite function 2 Setting for using password 3 Key-operator’s password 4 Setting for customer-engineer operation restriction function 5 Access denial due to failure in authentication of key-operator’s ID 6 Setting for HDD data encryption function 7 Cryptographic seed key for data stored on the hard disk drive By operating the control panel of MFP or the user’s client and performing copy, print, scan, or facsimile, used document data is stored on the hard disk drive built into MFP. At this time, security functions automatically operate according to the setting data in Table 1-1 before general user knows (when the “setting for HDD overwriting function for residual data” and the “setting for HDD data encryption CRP-C0080-01 4 function” are enabled, used document data is stored after being encrypted, and then overwritten and erased at the time of completion of each processing). 1.2.4 TOE Functionality TOE has the security functions described below: After the operation of copy, printer, scanner, and facsimile functions, this function overwrites and erases used document data stored on the hard disk drive. At the time of the operation of copy, printer, scanner, and facsimile functions, this function encrypts document data when storing it on the hard disk drive. This function identifies and authenticates key operator at the control panel or the key-operator’s client, and enables only the key operator to make settings on the TOE security functions described below: - Setting for HDD overwriting function for residual data - Setting for using password - Key-operator’s password - Access denial due to failure in authentication of key-operator’s ID - Setting for HDD data encryption function - Cryptographic seed key for data stored on the hard disk drive This function enables only the key operator to make the setting for customer-engineer operation restriction function. 1.3 Conduct of Evaluation Based on the IT Security Evaluation/Certification Program operated by the Certification Body, TOE functionality and its assurance requirements are being evaluated by evaluation facility in accordance with those publicized documents such as “IT Security Evaluation and Certification Scheme”[2], “IT Security Certification Procedure”[3] and “Evaluation Facility Approval Procedure”[4]. Scope of the evaluation is as follow. - Security design of the TOE shall be adequate; - Security functions of the TOE shall be satisfied with security functional requirements described in the security design; - This TOE shall be developed in accordance with the basic security design; - Above mentioned three items shall be evaluated in accordance with the CC Part 3 and CEM. More specific, the evaluation facility examined “Fuji Xerox Xerox WorkCentre 7228/7235/7245 Series Security Kit Security Target V1.02” as the basis design of security functions for the TOE (hereinafter referred to as “the ST”)[1], the evaluation deliverables in relation to development of the TOE and the development, manufacturing and shipping sites of the TOE. The evaluation facility evaluated if the TOE is satisfied both Annex B of CC Part 1 (either of [5], [8] or [11]) and Functional Requirements of CC Part 2 (either of [6], [9] or [12]) and also evaluated if the development, manufacturing and shipping environments for the TOE is also satisfied CRP-C0080-01 5 with Assurance Requirements of CC Part 3 (either of [7], [10] or [13]) as its rationale. Such evaluation procedure and its result are presented in “Xerox WorkCentre 7228/7235/7245 Series Security Kit Evaluation Technical Report Version 1.0” (hereinafter referred to as “the Evaluation Technical Report”) [17]. Further, evaluation methodology should comply with the CEM (either of [14], [15] or [16]). 1.4 Certification The Certification Body verifies the Evaluation Technical Report and Observation Report prepared by the evaluation facility and evaluation evidence materials, and confirmed that the TOE evaluation is conducted in accordance with the prescribed procedure. Certification review is also prepared for those concerns found in the certification process. Evaluation is completed with the Evaluation Technical Report dated 2007-01 submitted by the evaluation facility and those problems pointed out by the Certification Body are fully resolved and confirmed that the TOE evaluation is appropriately conducted in accordance with CC and CEM. The Certification Body prepared this Certification Report based on the Evaluation Technical Report submitted by the evaluation facility and concluded fully certification activities. 1.5 Overview of Report 1.5.1 PP Conformance There is no PP to be conformed. 1.5.2 EAL Evaluation Assurance Level of TOE defined by this ST is EAL2 conformance. 1.5.3 SOF This ST claims “SOF-basic” as its minimum strength of function. Attack level of the attackers assumed for this TOE is low level. Therefore, the claim of “SOF-basic” as the minimum function strength is appropriate. 1.5.4 Security Functions Security functions of the TOE are as follow. According to the ”setting for HDD overwriting function for residual data” that is set by key operator, this function overwrites and erases the used document data on the hard disk drive using the way described in Table 1-2. If overwriting of the used document data is not finished such as due to power shutdown, this function overwrites and erases the data at the next system booting because a list of the used document data that is to be overwritten and erased is in the hard disk drive. CRP-C0080-01 6 Table 1-2: Control of Overwriting Number of overwritings Data to overwrite with One time 0 Three times First time: random number Second time: random number Third time: 0 According the “setting for HDD data encryption function” that is set by key operator, this function encrypts document data stored on the hard disk drive. At the time of booting, TOE generates cryptographic key using the “cryptographic seed key for data stored on the hard disk drive” that is set by key operator. When storing document data on the hard disk drive, TOE stores the document data after performing encryption using the cryptographic key generated at the time of booting. When reading the stored document data, TOE also performs decryption using the cryptographic key generated at the time of booting. Cryptographic key is lost when the power of the mainframe of MFP is shut down. This function controls the operation of TOE setting data so that the operation can be performed by the authenticated key-operator. Before allowing the operation of TOE setting data, this function identifies and authenticates key operator with “key-operator’s user ID” and “key-operator’s password” entered at the control panel or through the Web browser of key-operator’s client. While “key-operator’s password” is being entered at the control panel or through the Web browser of key-operator’s client, asterisks (“*”) of the same number as the characters of the entered password are displayed in the “password” input field of the control panel or the Web browser of key-operator’s client. When the “key-operator’s user ID” and ”key-operator’s password” entered at the control panel or through the Web browser of key-operator’s client are correct and the identification/authentication of key operator succeeds, this function allows the operation of TOE setting data. When either of the “key-operator’s user ID” or ”key-operator’s password” entered at the control panel or through the Web browser of key-operator’s client is incorrect and the identification/authentication of key operator fails, this function displays identification/authentication error. When authentication fails the same number of times as that set in the “access denial due to failure in authentication of key-operator’s ID,” this function denies authentication. Only the key operator who is authenticated in the above-described way can set: - “HDD overwriting function for residual data” to “Not perform,” “Perform (one time),” or “Perform (three times).” - “setting for using password” to “Not perform” or “Perform.” - “HDD data encryption function” to “Not perform” or ”Perform.” - “key-operator’s password” to 7 to 12 alphanumeric characters. - “access denial due to failure in authentication of key-operator’s ID” to “Not perform” or ”Perform (1 to 10 times).” - “cryptographic seed key for data stored on the hard disk drive” to 12 alphanumeric characters. This function controls the operation of the TOE setting data for ”setting for customer-engineer operation restriction function” so that the operation can be performed by the authenticated key-operator. ”setting for customer-engineer operation restriction function” can be set to “Not perform” or “Perform”. By setting CRP-C0080-01 7 to “Perform,” customer engineer can be restricted from referring to / changing settings on TOE security functions. 1.5.5 Threat This TOE assumes such threats presented in Table 1-3 and provides functions for countermeasure to them. Table 1-3 Assumed Threats Identifier Threat T.RECOVER General user and the person who is not related to TOE might recover used document data such as by removing the hard disk drive and connecting it directly to a tool. T.CONFDATA General user and the person who is not related to TOE might change settings by accessing TOE setting data from the control panel or key-operator’s client. This setting data is allowed to be accessed only by key operator. 1.5.6 Organisational Security Policy No organizational security policies to comply with are required of the TOE utilized in organizations. 1.5.7 Configuration Requirements This product is offered as an optional product that is installed on Fuji Xerox’s digital multifunction machines [WorkCentre 7228], [WorkCentre 7235] and [WorkCentre 7245]. 1.5.8 Assumptions for Operational Environment Assumptions required in environment using this TOE presents in the Table 1-4. The effective performance of the TOE security functions are not assured unless these preconditions are satisfied. Table 1-4 Assumptions in Use of the TOE Identifier Assumptions A.SECMODE When operating TOE, key operator makes settings as follows: - Key-operator’s password: 7 to 12 characters - Setting for customer-engineer operation restriction function: “Perform” - Setting for using password: “Perform” - Access denial due to failure in authentication of key-operator’s ID: “Perform” and five times Additionally, key-operator’s password is managed so that it is prevented from being guessed or disclosed. CRP-C0080-01 8 Identifier Assumptions A.ADMIN Key operator has knowledge necessary to fulfill the assigned role and does not conduct improperly with malicious intention. A.NET MFP that TOE is installed on is connected to an internal network. This internal network constitutes an environment where interceptions are not made. Even when this internal network is connected to an external network, MFP cannot be accessed from the external network. 1.5.9 Documents Attached to Product Documents attached to the TOE are listed below. - Xerox WorkCentre 7228/7235/7245 System Administrator Guide Version : 701P44876 - Xerox WorkCentre 7228/7235/7245 Security Kit Supplementary Guide Version: XD3013EN0-1 CRP-C0080-01 9 2. Conduct and Results of Evaluation by Evaluation Facility 2.1 Evaluation Methods Evaluation was conducted by using the evaluation methods prescribed in CEM in accordance with the assurance requirements in CC Part 3. Details for evaluation activities are report in the Evaluation Technical Report. It described the description of overview of the TOE, and the contents and verdict evaluated by each work unit prescribed in CEM. 2.2 Overview of Evaluation Conducted The history of evaluation conducted was present in the Evaluation Technical Report as follows. Evaluation has started on 2006-12 and concluded by completion the Evaluation Technical Report dated 2007-01. The evaluation facility received a full set of evaluation deliverables necessary for evaluation provided by developer, and examined the evidences in relation to a series of evaluation conducted. Additionally, the evaluation facility directly visited the development and manufacturing sites on 2006-12 and examined procedural status conducted in relation to each work unit for configuration management and delivery and operation by investigating records and staff hearing. Further, the evaluation facility executed sampling check of conducted testing by developer and evaluator testing by using developer testing environment at developer site on 2006-12. Concerns found in evaluation activities for each work unit were all issued as Observation Report and were reported to developer. These concerns were reviewed by developer and all problems were solved eventually. As for concerns indicated during evaluation process by the Certification Body, the certification review was sent to the evaluation facility. These were reflected to evaluation after investigation conducted by the evaluation facility and the developer. 2.3 Product Testing Overview of developer testing evaluated by evaluator and evaluator testing conducted by evaluator are as follows. 2.3.1 Developer Testing 1) Developer Test Environment System configuration for the test that was conducted by developer is shown in Figure 2-1.

Test configuration System configuration for the test that was conducted by developer is shown in Figure 2-1. Developer testing was conducted in the same TOE test environment as the TOE configuration identified in ST. b. Testing Approach For the testing, following approach was used. 1. Method of directly observing the behavior of security functions from the external interfaces by stimulating the external interfaces of these functions by operating MFP and PCs. 2. Method of checking the behavior of the security functions of which behavior cannot be directly observed from the external interfaces (“HDD overwriting function for residual data” and “HDD data encryption function”) using the tools (debug serial and IDE monitor). Debug serial was connected via the original converter to MFP, and used for checking the condition of the data in the hard disk drive. IDE monitor was used for checking the contents of the data communicated between the controller board and the hard disk drive in MFP by monitoring the communicated data. By generating pseudo-errors of the hard disk drive by connecting the trunk cable, which has a switch to turn off the power of the hard disk drive, to the hard disk drive, the test on the operation errors of the overwriting and erasing function was conducted. c. Scope of Testing Performed CRP-C0080-01 11 Total number of test items was 28. The number of test items for testing each security function was as follows: - HDD overwriting function for residual data: 19 items - HDD data encryption function: 4 items - Key-operator authentication function: 4 items - Customer-engineer operation restriction function: 1 item The test covered the behavior of each function, and the overall test volume and scope were appropriate. d. Result As for the result of developer testing, the actual test-result was confirmed to match the expected test-result. Evaluator checked the validity of the methods to conduct developer testing and the test items, and confirmed that the methods and the result match those described in the “Test Plan and Report.” 2.3.2 Evaluator Testing 1) Evaluator Test Environment Configuration of the system used for evaluator testing is shown in Figure 2-2.

Test configuration System configuration for the test that was conducted by evaluator is shown in CRP-C0080-01 12 Figure 2-2. Evaluator testing was conducted in the same TOE test environment as the TOE configuration identified in ST. b. Testing Approach Evaluator conducted the test in the same approach as those for developer testing based on the judgment that the testing methods implemented by developer are suitable to verify the expected behavior of security functions. c. Scope of Testing Performed Evaluator conducted the 24-item test (3 items created uniquely by evaluator, 16 items conducted by sampling evaluator testing, and 5 items of intrusion test). The test created uniquely by evaluator was conducted by considering the accuracy of the developer testing for security functions. For sampling test, 16 items, which are 57 % of the 28 items of the test conducted by developer, were selected. For intrusion test, vulnerability analysis was conducted based on the result of developer vulnerability analysis, and 5-item test was conducted based on this analysis result. d. Result Evaluator was able to check the behavior of TOE by correctly completing all the tests conducted by evaluator, and confirmed that all the test results match the expected behavior. 2.4 Evaluation Result The evaluator had the conclusion that the TOE satisfies all work units prescribed in CEM by submitting the Evaluation Technical Report.
