ADD-GAP was designed as USB 2.0 mass storage controller with standard USB 2.0 Specification for both MASTER and SLAVE drive, it has fake capacity of 8GB only, support plug & play feature and not need any additional driver to be installed on the PC. 2 (ADD-GAP) is the product designed and manufactured by Advanced Product Design Sdn Bhd. ADD-GAP provides an absolute deterministic one-way unidirectional flow of any data and information between a source domain, the USB sending host system; tablet; android; laptop; PDA; network to a destination domain, the USB or host system/network that identified in this Security Target (Ref [6]). 3 There is no storage on the device itself and it only acts as a gateway to send data over from sender to receiver side. The MASTER drive is a write only fake USB storage drive whereas the SLAVE drive is a read only USB storage device with HID interface. 4 ADD-GAP is driverless which means no software is required on the sender side. Only a receiver program on the receiver side is required to handle the file transfers and destination folder.

Since we have established that the TOE provides an absolute deterministic one-way unidirectional flow of any data and information between two devices, there is no way to extract the data from the ADD-GAP Receive-Only side, thus achieving user data protection. • Protection of the TSF ADD-GAP offers passive detection of physical attack, it provides for features that indicate when a TSF device or TSF element is subject to tampering. However, notification of tampering is not automatic; an authorised user must perform manual physical inspection to determine if tampering has occurred. 1.4.2 Physical Boundaries 10 The TOE consists of two microchips i.e. Sender and Receiver. These two microchips are physically connected to each other on a printed circuit board (PCB). 11 The supporting hardware and software for TOE are as following: a) Universal serial bus (USB) Universal serial bus, USB is a plug and play interface that allows a computer to communicate with peripheral and other devices. b) Computers/ Laptops/ Servers (Private Devices) The TOE will connect public and private devices for data transfer purpose. The connection will be established via USB port of the computer/ Laptops/ Servers. The PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 5 of 19 PUBLIC private device will be the machine to receive data and must running in Microsoft Windows based operating system. c) Computers/ Laptops/ Servers (Public Devices) The TOE will connect public and private devices for data transfer purpose. The connection will be established via USB port of the computer/ Laptops/ Servers. The public device will be the machine to send data. d) DiodeCore.dll The core engine that consists all the core functions for Diode Receiver (Windows application) to communicate with ADD-GAP. e) DiodeDecode.dll All sub-functions used to decode received packets and generate the specific file. 1.5 Clarification of Scope 12 The TOE is designed to be suitable for use in accordance with user guidance that is supplied with the product. 13 Section 1.4 of this document describes the scope of the evaluation, which is limited to those claims made in the Security Target (Ref [6]). 14 Potential consumers of the TOE are advised that some functions and services of the overall product have not been evaluated as part of this evaluation. Potential consumers of the TOE should carefully consider their requirements for using functions and services outside of the evaluated configuration. 1.6 Assumptions 15 This section summarises the security aspects of the environment/configuration in which the product is intended to operate. Consumers should understand their own IT environment and requirements for secure operation of the TOE as defined in the Security Target (Ref [6]). 1.6.1 Environmental assumptions 16 Assumptions for the TOE environment as described in the Security Target (Ref[6]): PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 6 of 19 PUBLIC Table 2 : Assumptions for the TOE environment Assumption Statements A.USER The users are trusted; the users shall not maliciously compromise the security functionality of the TOE. The users are well-trained; the user shall comply to the operating procedures stipulated in the user guidance. A.DATAFLOW The data flow between Public Device and Private Device must pass through the TOE and there will be no other connection between Public Device and Private Device. 1.7 Evaluated Configuration 17 ADD-GAP may be deployed in a number of configurations consistent with the requirements as below: a) Domain Separation The TOE does not provide security domains to potentially-harmful entities. The TOE management functionality described does not provide security domains, but is a direct implementation of the security requirements. In short, security domains are not applicable for this TOE. b) Initialisation After the TOE securely delivered to the customer, the TOE will be usable directly based on the Operation Steps in APD [ADD-GAP] Diode Receiver (DR) Software User Guideline-ver3.0. c) Protection from Tampering - Physical Protection: ADD-GAP come with a hard metal case to protect the microchip and circuit board of the TOE. Additionally, the programming pin of the microchip is sealed with Epoxy Resins. - Logical: Logical protection is not applicable for the TOE device. This is due to no authentication feature been implemented at the TOE. PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 7 of 19 PUBLIC d) Protection from Bypassing TSF ensures that the security functionality is always invoked and hence, with the self-protection (as described earlier in this document) and correct functional behaviour (as described in the FSP/TDS evaluation evidence), the SFRs are always enforced. 18 Figure 3 shows the testing environment to test the TOE. The TOE establish a communication bridge between two test machines via the Universal Serial Bus (USB) interface. The TOE consists of two microchips which is MASTER and SLAVE. These two microchips are logically connected to each other on a printed circuit board (PCB). MASTER is connected to the sender device while SLAVE is connected to the receiver device. “DiodeCore.dll” is the core library file for “DiodeReceiver.exe”, which will be used to control the file transfer process. Figure 3 - Independent TOE Testing Environment 19 Figure 4 shows the testing environment for microchip firmware testing. Test jig is connected to the test machine via USB port and the application named MPLAB Integrated Programming Environment (IPE) is loaded in the test machine. Test jig is used to connect the programming pin on the TOE to the test machine thus allow MPLAB Integrated Programming Environment (IPE) to read the microchip firmware.

The evaluation was conducted at Evaluation Assurance Level 2. The evaluation was performed conformant to the MyCC Scheme Requirement (MyCC_REQ) (Ref [4]) and ISCB Evaluation Facility Manual (ISCB_EFM) (Ref [5]). 2.1 Evaluation Analysis Activities 31 The evaluation activities involved a structured evaluation of the TOE, including the following components: 2.1.1 Life-cycle support 32 An analysis of the TOE configuration management system and associated documentation was performed. The evaluators found that the configuration items were clearly and uniquely labelled, and that the access control measures as described in the configuration management documentation are effective in preventing unauthorised access to the configuration items. The developer’s configuration management system was evaluated, and it was found to be consistent with the provided evidence. 33 The evaluators examined the delivery documentation and determined that it described all of the procedures required to maintain the integrity of the TOE during distribution to the consumer. 2.1.2 Development 34 The evaluators analyzed the TOE functional specification; they determined that the design completely and accurately describes the TOE security functionality interfaces (TSFIs), and how the TOE security function (TSF) implements the security functional requirements (SFRs). 35 The evaluators examined the TOE design specification; they determined that the structure of the entire TOE is described in terms of subsystems. They also determined that, it provides a complete, accurate, and high-level description of the SFR-enforcing behavior of the SFR-enforcing subsystems. PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 11 of 19 PUBLIC 36 The evaluators examined the TOE security architecture description; they determined that the information provided in the evidence is presented at a level of detail commensurate with the descriptions of the SFR-enforcing abstractions contained in the functional specification and TOE design. 37 At the end, the evaluators confirmed that all the requirements for this class were fulfilled and passed. 2.1.3 Guidance documents 38 The evaluators examined the TOE preparative user guidance and operational user guidance, and determined that it sufficiently and unambiguously described how to securely transform the TOE into its evaluated configuration, and how to use and administer the product in order to fulfil the security objectives for the operational environment. The evaluators examined and tested the preparative and operational guidance, and determined that they were complete and sufficiently detailed to result in a secure configuration. 39 The evaluators confirmed that the TOE guidance was fulfilled all the requirements and passed for this class. 2.1.4 IT Product Testing 40 Testing at EAL 2 consists of assessing developer tests, performing independent functional test, and conducting penetration tests. The TOE testing was conducted by Cybertronics Lab. The detailed testing activities, including configurations, procedures, test cases, expected results and actual results are documented in a separate Test Plan Report. 2.1.4.1 Assessment of Developer Tests 41 The evaluators verified that the developer has met their testing responsibilities by repeating some developer test, as documented in the Evaluation Technical Report (Ref [7]) (not a public document because it contains information proprietary to the developer and/or the evaluator). The results of the evaluators’ tests are consistent with the developers’ test results defined in their evaluation evidences submitted. 2.1.4.2 Independent Functional Testing 42 At EAL 2, independent functional testing is the evaluation conducted by evaluators based on the information gathered by examining design and guidance documentation, PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 12 of 19 PUBLIC examining developer’s test documentation, executing a subset of the developer’s test plan, and creating test cases that are independent of the developer’s tests. 43 All testing was planned and documented to a sufficient level of detail to allow repeatability of the testing procedures and results. The results of the independent functional tests were recorded by the evaluators and are consistent with the expected test results in the test documentation.

Passed. 44 All testing performed by evaluators produced the expected results and as such the TOE behaved as expected. 2.1.4.3 Vulnerability Analysis 45 The evaluators performed a vulnerability analysis of the TOE in order to identify potential vulnerabilities in the TOE. This vulnerability analysis considered public domain sources and an analysis of guidance documentation, functional specification, TOE design, and security architecture description. 46 From the vulnerability analysis, the evaluators conducted penetration testing to determine that the TOE is resistant to attack performed by an attacker possessing a basic attack potential. The following factors have been taken into consideration during penetration tests: a) Any public knowledge of the vulnerability or known exploit; b) Specialist technical expertise required (specialised expertise); c) Knowledge of the TOE design and operation (knowledge of the TOE); d) Window of opportunity; and e) IT hardware/software or other equipment required for exploitation. 2.1.4.4 Vulnerability testing 47 The penetration tests focused on: a) Code Tempering and Reverse Engineering b) Extraneous Functionality c) Client Code Quality 48 The result of the penetration testing noted that there is no residual vulnerability found. However, it is important to ensure that the TOE is use only in its evaluated configuration and in secure environment as specified in the Security Target (Ref[6]). PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 14 of 19 PUBLIC 2.1.4.5 Testing Results 49 Tests conducted for the TOE produced the expected results and demonstrated that the product behaved as specified in its Security Target (Ref [6]) and its functional specification. Therefore, the certifiers confirmed that all the test conducted were PASSED as expected. PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 15 of 19 PUBLIC 3 Result of the Evaluation 50 After due consideration during the oversight of the execution of the evaluation by the certifiers and of the Evaluation Technical Report (Ref[7]), the Malaysian Common Criteria Certification Body certifies the evaluation of Amaris Data Diode for Air Gap (ADD-GAP) v 2.0.112 which is performed by Cybertronics Lab. 51 Cybertronics Lab found that Amaris Data Diode for Air Gap (ADD-GAP) v 2.0.112 upholds the claims made in the Security Target (Ref [6]) and supporting documentations, and has met the requirements of the Common Criteria (CC) Evaluation Assurance Level 2. 52 Certification is not a guarantee that a TOE is completely free of exploitable vulnerabilities. There will remain a small level of risk that exploitable vulnerabilities remain undiscovered in its claimed security functionality. The risk is reduced as the certified level of assurance increases for the TOE. 3.1 Assurance Level Information 53 EAL 2 provides assurance by a full security target and analysis of the SFRs in that Security Target, using functional and interface specifications, guidance documentation and a description of the design of the TOE and the implementation to understand the security behaviours. 54 The analysis is supported by independent testing of the TSF, evidence of developer testing based on the functional specification, selective independent confirmation of the developer test results, and a vulnerability analysis (based upon the functional specification, TOE design, security architecture description and guidance evidence provided) demonstrating resistance to penetration attackers with a basic attack potential. 55 EAL 2 also provides assurance through use of a configuration management system and evidence of secure delivery procedures. 3.2 Recommendation 56 The Malaysian Certification Body (MyCB) is strongly recommended that: a) A strict adherence to guidance documentations and procedures provided by the developer are highly recommended. PUBLIC FINAL C110 Certification Report ISCB-5-RPT-C110-CR-v1 Page 16 of 19 PUBLIC b) The TOE users should be aware and implement available security or critical updates related to the TOE security features and its supporting hardware, software, firmware or relevant guidance documents. c) Users are advice to seek assistance or guidance directly from the developer of the TOE if specific requirements shall be configured or implemented by the TOE to meet certain policies, procedures and security enforcement within the users’ organization. This is important in order to reduce operational error, misconfiguration, malfunctions or insecure operations of the TOE that may compromise the confidentiality, integrity and availability of the assets that is protected by the TOE.
