Preliminary Remarks Under the BSIG1 Act, the Federal Office for Information Security (BSI) has the task of issuing certificates for information technology products. Certification of a product is carried out on the instigation of the vendor or a distributor, hereinafter called the sponsor. A part of the procedure is the technical examination (evaluation) of the product according to the security criteria published by the BSI or generally recognised security criteria. The evaluation is normally carried out by an evaluation facility recognised by the BSI or by BSI itself. The result of the certification procedure is the present Certification Report. This report contains among others the certificate (summarised assessment) and the detailed Certification Results. The Certification Results contain the technical description of the security functionality of the certified product, the details of the evaluation (strength and weaknesses) and instructions for the user. 2. Specifications of the Certification Procedure The certification body conducts the procedure according to the criteria laid down in the following: ● Act on the Federal Office for Information Security1 ● BSI Certification and Approval Ordinance2 ● BSI Schedule of Costs3 ● Special decrees issued by the Bundesministerium des Innern (Federal Ministry of the Interior) ● DIN EN ISO/IEC 17065 standard ● BSI certification: Scheme documentation describing the certification process (CC- Produkte) [3] ● BSI certification: Scheme documentation on requirements for the Evaluation Facility, its approval and licencing process (CC-Stellen) [3] 1 Act on the Federal Office for Information Security (BSI-Gesetz - BSIG) of 14 August 2009, Bundesgesetzblatt I p. 2821 2 Ordinance on the Procedure for Issuance of Security Certificates and approval by the Federal Office for Information Security (BSI-Zertifizierungs- und -Anerkennungsverordnung - BSIZertV) of 17 December 2014, Bundesgesetzblatt 2014, part I, no. 61, p. 2231 3 Schedule of Cost for Official Procedures of the Bundesamt für Sicherheit in der Informationstechnik (BSI-Kostenverordnung, BSI-KostV) of 3 March 2005, Bundesgesetzblatt I, p. 519 6 / 22 BSI-DSZ-CC-1096-2021 Certification Report ● Common Criteria for IT Security Evaluation (CC), Version 3.14 [1] also published as ISO/IEC 15408. ● Common Methodology for IT Security Evaluation (CEM), Version 3.1 [2] also published as ISO/IEC 18045 ● BSI certification: Application Notes and Interpretation of the Scheme (AIS) [4] 3. Recognition Agreements In order to avoid multiple certification of the same product in different countries a mutual recognition of IT security certificates - as far as such certificates are based on ITSEC or CC - under certain conditions was agreed. 3.1. European Recognition of CC – Certificates (SOGIS-MRA) The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in April 2010. It defines the recognition of certificates for IT-Products at a basic recognition level and, in addition, at higher recognition levels for IT-Products related to certain SOGIS Technical Domains only. The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels EAL 1 to EAL 4. For "Smartcards and similar devices" a SOGIS Technical Domain is in place. For "HW Devices with Security Boxes" a SOGIS Technical Domains is in place, too. In addition, certificates issued for Protection Profiles based on Common Criteria are part of the recognition agreement. The current list of signatory nations and approved certification schemes, details on recognition, and the history of the agreement can be seen on the website at https://www.sogis.eu. The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the terms of this agreement by the related bodies of the signatory nations. A disclaimer beneath the logo indicates the specific scope of recognition. This certificate is recognized according to the rules of SOGIS-MRA, i.e. up to and including CC part 3 EAL 4 components. The evaluation contained components above EAL 4 that are not mutually recognised in accordance with the provisions of the SOGIS MRA. For mutual recognition the EAL 4 components of these assurance families are relevant. 3.2. International Recognition of CC – Certificates (CCRA) The international arrangement on the mutual recognition of certificates based on the CC (Common Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08 September 2014. It covers CC certificates based on collaborative Protection Profiles (cPP) (exact use), CC certificates based on assurance components up to and including EAL 2 or the assurance family Flaw Remediation (ALC_FLR) and CC certificates for Protection Profiles and for collaborative Protection Profiles (cPP). The current list of signatory nations and approved certification schemes can be seen on the website: https://www.commoncriteriaportal.org. The Common Criteria Recognition Arrangement logo printed on the certificate indicates that this certification is recognised under the terms of this agreement by the related bodies 4 Proclamation of the Bundesministerium des Innern of 12 February 2007 in the Bundesanzeiger dated 23 February 2007, p. 3730 7 / 22 Certification Report BSI-DSZ-CC-1096-2021 of the signatory nations. A disclaimer beneath the logo indicates the specific scope of recognition. This certificate is recognized according to the rules of CCRA-2014, i. e. up to and including CC part 3 EAL 2+ ALC_FLR components. 4. Performance of Evaluation and Certification The certification body monitors each individual evaluation to ensure a uniform procedure, a uniform interpretation of the criteria and uniform ratings. The product Arbit Data Diode 10 GbE, v1.00 has undergone the certification procedure at BSI. The evaluation of the product Arbit Data Diode 10 GbE was conducted by TÜV Informationstechnik GmbH. The evaluation was completed on 17 March 2021. TÜV Informationstechnik GmbH is an evaluation facility (ITSEF)5 recognised by the certification body of BSI. For this certification procedure the sponsor and applicant is: Arbit Cyber Defence Systems ApS. The product was developed by: Arbit Cyber Defence Systems ApS. The certification is concluded with the comparability check and the production of this Certification Report. This work was completed by the BSI. 5. Validity of the Certification Result This Certification Report applies only to the version of the product as indicated. The confirmed assurance package is valid on the condition that ● all stipulations regarding generation, configuration and operation, as given in the following report, are observed, ● the product is operated in the environment described, as specified in the following report and in the Security Target. For the meaning of the assurance components and assurance levels please refer to CC itself. Detailed references are listed in part C of this report. The Certificate issued confirms the assurance of the product claimed in the Security Target at the date of certification. As attack methods evolve over time, the resistance of the certified version of the product against new attack methods needs to be re-assessed. Therefore, the sponsor should apply for the certified product being monitored within the assurance continuity program of the BSI Certification Scheme (e.g. by a re-assessment or re-certification). Specifically, if results of the certification are used in subsequent evaluation and certification procedures, in a system integration process or if a user's risk management needs regularly updated results, it is recommended to perform a re- assessment on a regular e.g. annual basis. In order to avoid an indefinite usage of the certificate when evolved attack methods would require a re-assessment of the products resistance to state of the art attack methods, the maximum validity of the certificate has been limited. The certificate issued on 7 April 2021 is valid until 6 Aprilg 2026. Validity can be re-newed by re-certification. 5 Information Technology Security Evaluation Facility 8 / 22 BSI-DSZ-CC-1096-2021 Certification Report The owner of the certificate is obliged: 1. when advertising the certificate or the fact of the product's certification, to refer to the Certification Report as well as to provide the Certification Report, the Security Target and user guidance documentation mentioned herein to any customer of the product for the application and usage of the certified product, 2. to inform the Certification Body at BSI immediately about vulnerabilities of the product that have been identified by the developer or any third party after issuance of the certificate, 3. to inform the Certification Body at BSI immediately in the case that security relevant changes in the evaluated life cycle, e.g. related to development and production sites or processes, occur, or the confidentiality of documentation and information related to the Target of Evaluation (TOE) or resulting from the evaluation and certification procedure where the certification of the product has assumed this confidentiality being maintained, is not given any longer. In particular, prior to the dissemination of confidential documentation and information related to the TOE or resulting from the evaluation and certification procedure that do not belong to the deliverables according to the Certification Report part B, or for those where no dissemination rules have been agreed on, to third parties, the Certification Body at BSI has to be informed.

Certification Results The following results represent a summary of ● the Security Target of the sponsor for the Target of Evaluation, ● the relevant evaluation results from the evaluation facility, and ● complementary notes and stipulations of the certification body. 10 / 22 BSI-DSZ-CC-1096-2021 Certification Report 1. Executive Summary The Target of Evaluation (TOE) is the Arbit Data Diode 10GbE Version 1.00, developed by Arbit Cyber Defence Systems ApS. In its intended use case, the TOE contains a photodiode to convert an optical signal at its input port to an electrical signal at the output port. Additionally, the TOE implements a one- way data flow policy, i.e., information entering the TOE at its output port is not emitted at the input port in case customers follow the security requirements provided in the installation guidance document. The TOE acts on the first level of the ISO/OSI reference model, i.e., no logical behaviour is implemented. This results in the fact that the TOE does not provide a configuration interface, return values or error messages. The Security Target [6] and [9] is the basis for this certification. It is not based on a certified Protection Profile. The TOE Security Assurance Requirements (SAR) are based entirely on the assurance components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details). The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 7 augmented by ALC_FLR.1. The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the Security Target [6] and [9], chapter 7. They are all selected from Common Criteria Part 2. Thus the TOE is CC Part 2 conformant. The TOE Security Functional Requirements are implemented by the following TOE Security Functionality: TOE Security Functionality Addressed issue One-Way Information Flow The TOE implements the one-way data diode through a repeater, where a fiber optic network cable is connected to the INPUT port and a Receiver connection on the OUTPUT port. Information can only be received from the Sending network connected on the INPUT port, and no information can spill over to the INPUT port from the OUTPUT port. Information received on the INPUT port is allowed to exit through the OUTPUT port, without further processing. Table 1: TOE Security Functionalities For more details please refer to the Security Target [6] and [9], chapters 2.2 and 4.3. The assets to be protected by the TOE are defined in the Security Target [6] and [9], chapter 4.1 . Based on these assets the TOE Security Problem is defined in terms of Assumptions, Threats and Organisational Security Policies. This is outlined in the Security Target [6] and [9], chapter 4. This certification covers the configurations of the TOE as outlined in chapter 8. The vulnerability assessment results as stated within this certificate do not include a rating for those cryptographic algorithms and their implementation suitable for encryption and decryption (see BSIG Section 9, Para. 4, Clause 2). 11 / 22 Certification Report BSI-DSZ-CC-1096-2021 The certification results only apply to the version of the product indicated in the certificate and on the condition that all the stipulations are kept as detailed in this Certification Report. This certificate is not an endorsement of the IT product by the Federal Office for Information Security (BSI) or any other organisation that recognises or gives effect to this certificate, and no warranty of the IT product by BSI or any other organisation that recognises or gives effect to this certificate, is either expressed or implied. 2. Identification of the TOE The Target of Evaluation (TOE) is called: Arbit Data Diode 10 GbE. The following table outlines the TOE deliverables: No Type Identifier Release Form of Delivery 1 HW Arbit Data Diode 10GbE v1.00 Personal hand-over of sealed SFP+ module (see below). 2 DOC Arbit Data Diode 10GbE – Integration Guide V1.08, 2020-10- 21 Personal hand-over in paper format (see below). Table 2: Deliverables of the TOE Regarding delivery: As it is stated in the Security targets [6] and [9] section 2.1.1, the “delivery of TOE and its Integration Guide shall be performed as trusted personal handover in accordance with the delivery procedure”. Thus, delivery is conducted by the following ways: • Announced delivery: The recipient knows the expected time of delivery window and forwarder company. The recipient shall accept deliveries as announced, otherwise shall contact the sender. • Personal handover: The delivered items are personally handed over to the forwarder and the forwarder personally handover the delivery to the consumer. The developer shall be informed of the successful handover. • Known forwarder: The respective parties know the forwarder. The identity of the forwarder shall be verified before handing over items. • Independent delivery of TOE parts: TOE parts shall be delivered independently. The TOE parts may be sent by different forwarders or on different days. One forwarder shall never have the TOE and its guidance at the same time The consumer shall verify Independence of delivery before accepting the complete delivery. Regarding identification: The TOE and its reference are part of the Integration Guidance [11] (section 2), and the TOE itself is labelled accordingly (part of considerations of assurance family ALC_CMS). 12 / 22 BSI-DSZ-CC-1096-2021 Certification Report The independent delivery of TOE parts and the correct labelling of the TOE enable consumer of secure reception of the TOE and its guidance, maintaining authenticity and integrity during delivery. 3. Security Policy The Security Policy is expressed by the set of Security Functional Requirements and implemented by the TOE. It covers the following issues: The security functionality of the TOE is to implement the one-was data flow policy. While in its intended use case, the TOE converts an optical signal at its input port to an electrical signal at its output port, the TOE makes sure that no data or information is transmitted from its output port to the input port. In fact, when operated as described in the user guidance [11], the TOE is not able to emit light that contains information about any signal applied to the electrical output. Specific details concerning the above mentioned security policy can be found in [6] and [9], chapters 2.1.2, 7.1, and 7.6. 4. Assumptions and Clarification of Scope The Assumptions defined in the Security Target and some aspects of Threats and Organisational Security Policies are not covered by the TOE itself. These aspects lead to specific security objectives to be fulfilled by the TOE-Environment. The following topics are of relevance: The Security Objective for the Operational Environment OE.INTEGRATOR requires integrators performing the installation of the TOE to be well-trained and competent in the prevention of signal leakage. Furthermore, integrators shall adhere to the guidance. In [11] section 2.2, the developer states that the integrator who is performing the installation has to apply procedures applicable to the respective operational environment such that proper protection of the TOE is maintained at all times. The Security Objective for the Operational Environment OE.PHYSICAL requires that the TOE and its interfaces shall be physically protected from unauthorized access. In [11] section 2.2 and 2.4, the developer clearly states that no user may have physical access to the TOE. If an integrity breach is possible (identified by the means implemented by the integrator), the TOE shall not be used. The Security Objective for the Operational Environment OE.POWER requires that the power supply of the TOE shall be 3.3V +/- 5% and that the minimum current capacity (continuous and peak-to-peak) shall be 500 mA. Guidance document [11] section 2.3.3 addresses this OE accordingly. 5. Architectural Information Details on architectural information can be found in the Security Target [6] and [9], section 2. 13 / 22 Certification Report BSI-DSZ-CC-1096-2021 6. Documentation The evaluated documentation as outlined in table 2 is being provided with the product to the customer. This documentation contains the required information for secure usage of the TOE in accordance with the Security Target. Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of this report have to be followed. 7. IT Product Testing Both the developer as well as ITSEF conducted product testing. Regarding the developer testing: The developer conducted tests during development of the TOE and conducted tests for each produced device: • The development tests are suitable verify that the TSF behaves as specified in ADV_FSP, ADV_TDS, and ADV_IMP. • The production tests are used to check that a produced product matches the expected behavior derived from the development tests. The following TOE security functionalities were tested by the developer: • FDP_IFC.2 Complete information flow control, and • FDP_IFF.1 Simple security attributes. Regarding ITSEF testing: • Functional verification of the TOE interfaces (TSFI), • Functional verification of the TOE design providing assurance that the product matches the implementation representation, • Functional production tests as a sanity check of the core features of the manufactured device, • Penetration testing. SFRs penetration tested by the ITSEF: • FDP_IFC.2 Complete information flow control, and • FDP_IFF.1 Simple security attributes. The overall ITSEF verdict is: The penetration tests results confirm that the TOE is resistant to attackers with high attack potential in the intended operational environment. 8. Evaluated Configuration The TOE is available in a single variant and cannot be further configured. 14 / 22 BSI-DSZ-CC-1096-2021 Certification Report 9. Results of the Evaluation 9.1. CC specific results The Evaluation Technical Report (ETR) [7] was provided by the ITSEF according to the Common Criteria [1], the Methodology [2], the requirements of the Scheme [3] and all interpretations and guidelines of the Scheme (AIS) [4] as relevant for the TOE. The Evaluation Methodology CEM [2] was used for those components up to EAL 5 extended by advice of the Certification Body for components beyond EAL 5. The following guidance specific for the certification procedure was used: • AIS1: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 1, Durchführung der Ortsbesichtigung in der Entwicklungsumgebung des Herstellers, Version 14, 2017-10-11, Bundesamt für Sicherheit in der Informationstechnik, • AIS14: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 14, Anforderungen an Aufbau und Inhalt der ETR-Teile (Evaluation Technical Report) für Evaluationen nach CC (Common Criteria), Version 7, 2010-08-03, Bundesamt für Sicherheit in der Informationstechnik, • AIS19: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 14, Anforderungen an Aufbau und Inhalt der ETR-Teile (Evaluation Technical Report) für Evaluationen nach CC (Common Criteria), Version 7, 2010-08-03, Bundesamt für Sicherheit in der Informationstechnik, • AIS32: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 14, Anforderungen an Aufbau und Inhalt der ETR-Teile (Evaluation Technical Report) für Evaluationen nach CC (Common Criteria), Version 7, 2010-08-03, Bundesamt für Sicherheit in der Informationstechnik, • AIS34: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 14, Anforderungen an Aufbau und Inhalt der ETR-Teile (Evaluation Technical Report) für Evaluationen nach CC (Common Criteria), Version 7, 2010-08-03, Bundesamt für Sicherheit in der Informationstechnik, • AIS39: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 14, Anforderungen an Aufbau und Inhalt der ETR-Teile (Evaluation Technical Report) für Evaluationen nach CC (Common Criteria), Version 7, 2010-08-03, Bundesamt für Sicherheit in der Informationstechnik, • AIS45: Anwendungshinweise und Interpretationen zum Schema (AIS) – AIS 45, Erstellung und Pflege von Meilensteinplänen, Version 2, 2010-08-03, Bundesamt für Sicherheit in der Informationstechnik. As a result of the evaluation the verdict PASS is confirmed for the following assurance components: ● All components of the EAL 7 package including the class ASE as defined in the CC (see also part C of this report) ● The components ALC_FLR.1 augmented for this TOE evaluation. The evaluation thus has confirmed: ● for the Functionality: Product specific Security Target Common Criteria Part 2 conformant 15 / 22 Certification Report BSI-DSZ-CC-1096-2021 ● for the Assurance: Common Criteria Part 3 conformant EAL 7 augmented by ALC_FLR.1 For specific evaluation results regarding the development and production environment see annex B in part D of this report. The results of the evaluation are only applicable to the TOE as defined in chapter 2 and the configuration as outlined in chapter 8 above. 9.2. Results of cryptographic assessment The TOE does not include cryptographic mechanisms. Thus, no such mechanisms were part of the assessment. 10. Obligations and Notes for the Usage of the TOE The documents as outlined in table 2 contain necessary information about the usage of the TOE and all security hints therein have to be considered, especially the implementation guidance [11]. In addition all aspects of Assumptions, Threats and OSPs as outlined in the Security Target not covered by the TOE itself need to be fulfilled by the operational environment of the TOE. In detail, the assumptions on the operational environment need to be taken into account by customers: Assumption Definition A.INTEGRATOR The integrator who is performing the installation of the TOE is well-trained and competent in the prevention of signal leakage, and will properly adhere to the TOE guidance. A.PHYSICAL The TOE and its interfaces will be physically protected from unauthorized access and mechanical, electrical, optical, radiation or any other form of physical influence. A.POWER Power supply to TOE shall be 3.3 V +/-5%. The minimum current capacity, both continuous and peak, shall be 500 mA. Table 3: Assumptions on the operational environment The customer or user of the product shall consider the results of the certification within his system risk management process. In order for the evolution of attack methods and techniques to be covered, he should define the period of time until a re-assessment of the TOE is required and thus requested from the sponsor of the certificate. The limited validity for the usage of cryptographic algorithms (if any) as outlined in chapter 9 has to be considered by the user and his system risk management process, too. For this reason the TOE includes guidance documentation (see table 2) which contains obligations and guidelines for users of the product layer on top on how to securely use this certified TOE and which (e.g. organisational measures of delivery) measures have to be implemented in order to fulfil the security requirements of the Security Target of the TOE. In the course of the evaluation of the composite product or system it must be examined if the required measures have been correctly and effectively implemented by the product layer on top. 16 / 22 BSI-DSZ-CC-1096-2021 Certification Report 11.
