The TOE will be used within the Tachograph System as a security medium which carries a specific Tachograph Application intended for its use with the recording equipment. The basic functions of the Tachograph Card are: · to store card identification and card holder identification data. These data are used by the vehicle unit to identify the cardholder, provide accordingly functions and data access rights, and ensure cardholder accountability for his activities, · to store cardholder activities data, events and faults data and control activities data, related to the cardholder. A Tachograph Card is therefore intended to be used by a card interface device of a vehicle unit. It may also be used by any card reader (e.g. of a personal computer) which shall have full read access right on any user data. During the end-usage phase of a Tachograph Card life cycle (phase 7 of life-cycle as described), vehicle units only may write user data to the card. A Tachograph Card is either of the type Driver Card or Control Card or Workshop Card or Company Card as outlined in the ST [7], chapter 2.4. The TOE comprises the following components: · Integrated Circuit (IC) "Philips P16WX064V0C Secure 16-bit Smart Card Controller " provided by Philips Semiconductors GmbH · Caernarvon Cryptographic Library on Philips Smart XA2 as IC Dedicated Support Software provided by Philips Semiconductors GmbH · Smart Card Embedded Software based on a Java Card Platform Version 2.1.1 with a specific Java Card Applet for the Tachograph Application provided by ORGA Kartensysteme GmbH. The Java Card Applet for the Tachograph Application consists of a fix part con- taining the executable code and another configurable part for the Tachograph Card’s file system. The configuration of the Tachograph Card concerns the following points: · Choice of the card type: A complete Driver Card, Control Card, Workshop Card or Company Card with complete file system. Additionally, a General Tachograph Card is available that can be irreversibly converted into one of the different types Driver Card, Control Card, Workshop Card and Company Card by using a specific card command after initialisation resp. prior to the personalisation of the card. · Choice of the personalisation scheme: Securing the transfer of personalisation data can be done on base of a dynamic scheme (Secure B-3 Certification Report BSI-DSZ-CC-0267-2004 Messaging with a session key) or alternatively on base of a static scheme (Secure Messaging with a static key). The TOE is developed and constructed in full accordance with the Tachograph Card Specification [8], Annex 1B main body, Appendix 2, Appendix 10 (Tacho- graph Card Generic Security Target) and Appendix 11. In particular, this implies the conformance of the Tachograph Card with the following standards: ISO/IEC 7810 Identification cards – Physical characteristics, ISO/IEC 7816 Identification cards - Integrated circuits with contacts: part 1, part 2, part 3, part 4 and part 8; ISO/IEC 10373 Identification cards – Test methods. In order to achieve the required system security, the Tachograph Card and the corresponding ST [6] and [7] meet all the security requirements and evaluation conditions defined in the Tachograph Card’s “Generic Security Target” in [8], Appendix 10 under consideration of the interpretations in [9]. The life-cycle of the TOE conforms to the smart card life cycle described in Appendix 10 of [8] referring to PP/9911 [13]. The following table outlines this life-cycle for the TOE: Phase Description Phase 1 Smart Card Embedded Software Development The Smart Card Embedded Software Developer (ORGA Kartensysteme GmbH, Paderborn) is in charge of the Smart Card Embedded Software (Basic Software, Applica- tion Software) development and the specification of IC initialisation and pre-personalisation requirements. Phase 2 IC Development The IC Designer (Philips Semiconductors GmbH) designs the IC, develops IC Dedicated Software, provides informa- tion, software or tools to the Smart Card Embedded Soft- ware Developer, and receives the Smart Card Embedded Software (only Basic Software) from the developer through trusted delivery and verification procedures. The IC Designer constructs the smart card IC database, necessary for the IC photo mask fabrication. Phase 3 IC Manufacturing and Testing The IC Manufacturer (Philips Semiconductors GmbH) generates the masks for the IC manufacturing based upon an output from the smart card IC database. He is responsible for producing the IC through three main steps: IC manufacturing, IC testing, and IC pre- personalisation. Phase 4 IC Packaging and Testing The IC Packaging Manufacturer (ORGA Kartensysteme GmbH, Flintbek) is responsible for the IC packaging (pro- duction of modules) and testing. Phase 5 Smart Card Product Finishing Process The Smart Card Product Manufacturer (ORGA Kartensys- teme GmbH, Flintbek) is responsible for the initialisation of the TOE (in form of initialisation of the modules of phase 4) and its testing. In this phase the TOE becomes either the type Driver Card or Control Card or Workshop Card or B-4 BSI-DSZ-CC-0267-2004 Certification Report Phase Description Company Card. The smart card product finishing process comprises the embedding of the initialised modules for the TOE and the card production what is done alternatively by ORGA Kartensysteme GmbH or by the customer. Delivery of the TOE Two different ways for delivery are established: (i) The TOE is delivered to the customer in form of a complete (initialised) smart card. (ii) Alternatively, the TOE is delivered to the customer in form of an initialised module. In this case, the smart card finishing process (embedding, final tests) is task of the customer. Phase 6 Smart Card Personalisation The Personaliser is responsible for the smart card personalisation and final tests. Phase 7 Smart Card End-usage The Smart Card Issuer is responsible for the smart card product delivery to the smart card end-user, and the end of life process. Table 1: Life cycle of the TOE The evaluation of the TOE was conducted as a composition evaluation making use of the platform evaluation results of the CC evaluations · of the underlying semiconductor "Philips P16WX064V0C Secure 16-bit Smart Card Controller" provided by Philips Semiconductors GmbH [18] and · of the underlying semiconductor "Philips P16WX064V0C Secure 16-bit Smart Card Controller with Caernarvon Cryptographic Library on Philips Smart XA2 as IC Dedicated Support Software" provided by Philips Semi- conductors GmbH. For the re-certification, a reassessment of the hardware platform (Philips P16WX064V0C Secure 16-bit Smart Card Controller with Caernarvon Cryptographic Library) had been successfully carried out by T-Systems GEI GmbH. Both, the IC itself and the IC with its IC Dedicated Software were evaluated according to Common Criteria EAL 5 augmented with a minimum strength level for its security functions of SOF-high based on the Protection Profile BSI-PP- 0002 [12]. These platform evaluations were performed by T-Systems GEI GmbH. The Embedded Software of the “Tachograph Card Version 1.1 128/64 R1.1” and the overall composition was evaluated by SRC Security Research & Consulting GmbH. The concept for composition as outlined in CC Supporting Document [4, AIS 36] was used. B-5 Certification Report BSI-DSZ-CC-0267-2004 The evaluation was completed on 12 May 2004. Both, the SRC Security Research & Consulting GmbH and the evaluation facility of T-Systems GEI GmbH are evaluation facilities (ITSEF)8 recognised by BSI. The sponsor, vendor and distributor of the Tachograph Card Version 1.1 128/64 R1.1 is ORGA Kartensysteme GmbH. 1.1 Assurance package The TOE security assurance requirements 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 assurance level EAL4+ (Evaluation Assurance Level 4 augmented). The following table shows the augmented assurance components. Requirement Identifier EAL4 TOE evaluation: Methodically designed, tested, and reviewed +: ADO_IGS.2 Delivery and operation - Generation log +: ADV_IMP.2 Development - Implementation of the TSF +: ATE_DPT.2 Tests - Testing: low-level design +: AVA_VLA.4 Vulnerability assessment – Highly resistant Table 2: Assurance components and EAL-augmentation The level of assurance and the augmentations are chosen in order to allow the confirmation of equivalence to ITSEC [10] E3 high as required by Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8] and outlined in JIL Security Evaluation and Certification of Digital Tachographs [9]. 1.2 Functionality The TOE Security Functional Requirements (SFR) and TOE Security Functions are based on Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8] specified in the document JIL Security Evaluation and Certification of Digital Tachographs [9].

For more details please refer to the Security Target [7], chapter 3. 1.5 Special configuration requirements The TOE is delivered at the end of phase 5 in form of complete cards, i.e. after the initialisation process of the TOE has been successfully finished, final tests have been successfully conducted and the card production has been fulfilled. Alternatively, the TOE is delivered in form of initialised and tested modules. In this case, the smart card finishing process (embedding of the delivered modules, final tests) is task of the customer. A Tachograph Card may be of the following types: Driver Card, Control Card, Workshop Card or Company Card as defined in [8] depending on the specific applet and data loaded into the card. Alternatively, in case of the card type General Tachograph Card, the applet may contain code with a prepared file system for the four card types. In that case, after initialisation resp. prior to the personalisation of the card, one of the four prepared card types has to be created by usage of a specific card command. Two personalisation schemes are provided by the Tachograph Card: · Dynamic scheme with Secure Messaging using a session key: The Tachograph Card allows a personalisation only after a successful preceding mutual authentication between the TOE and the external world with agreement of a session key and send sequence counter and makes use of asymmetric keys. The keys necessary on the card for the authentication procedure are part of the Application Software resp. the Tachograph Applet and are loaded onto the card in the framework of the initialisation. The following data transfer of the personalisation data has to be conducted with Secure Messaging. B-13 Certification Report BSI-DSZ-CC-0267-2004 · Static scheme with Secure Messaging using a static key: The TOE allows a personalisation only under usage of a static symmetric personalisation key which is stored on the card during the initialisation of the card or later within an additional pre-personalisation phase. In the latter case, the symmetric key has to be loaded with a specific card command in encrypted form. In each case, the personalisation of the Tachograph Card requires a preceding authentication of the external world (personalisation unit). At the end of the personalisation process, the card is switched to the end-user operational phase. There are no special security measures for the start-up of the TOE besides the requirement that the TOE has to be used under the well-defined operating con- ditions and that the requirements on the personalisation and usage have to be applied as described in the user documentation [15], [16] and [17]. 1.6 Assumptions about the operating environment The TOE is intended to be used within the Tachograph System as a security medium which carries a specific Tachograph Application intended for its use with the recording equipment as specified in [8]. There do not exist any Tachograph Card specific assumptions for the environ- ment of the TOE. The following general assumptions are made based on the PP/9911 [13] and PP/9806 [14] referenced in Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8] (Generic Security Target).

The security of the personalisation process of the TOE is supported by the TOE itself. 1.7 Disclaimers 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.

The Tachograph Card Version 1.1 128/64 R1.1 Data Sheet includes File Control Information (FCI) which can be used for identification of the five different card types. 3 Security Policy The TOE will be employed within the Tachograph System as a security medium which carries a specific Tachograph Application intended for its use with the recording equipment. The TOE is the composition of the IC, IC Dedicated Software and Smart Card Embedded Software. The security policy is to provide: · protection against leakage of information (e.g. to ensure the confidential- ity of cryptographic keys during cryptographic functions performed by the TOE), against physical probing, against malfunctions, against physical manipulations, against access for code and data memory and against abuse of functionality · secure storage of user data and TSF data · access control to user data and TSF data according to the specified rules · secure communication to the vehicle unit of the Tachograph System as specified in Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8]. 13 see chapter 6 B-16 BSI-DSZ-CC-0267-2004 Certification Report 4 Assumptions and Clarification of Scope The TOE is intended to be used within the Tachograph System as a security medium which carries a specific Tachograph Application intended for its use with the recording equipment as specified in [8]. There do not exist any Tachograph Card specific assumptions for the environ- ment of the TOE as the definition of the card type is done before the TOE personalisation in phase 6 before delivery. General assumptions are made based on the PP/9911 [13] and PP/9806 [14] referenced in Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8] (Generic Security Target). These general assumptions are structured according to the phases of the life cycle. Some of these assumptions are related to proce- dures in phases 1 to 5. These phases were part of the TOE evaluation. As delivery of the TOE is defined within or at the end of phase 5 of the life cycle. (see table 1), the phases 6 and 7 are the usage phases of the TOE. Procedures related to assumptions on these phases and the additional assumption A.PERS on secure generation and handling of personalisation data are outlined in the user documentation. The TOE is the Tachograph Card Version 1.1 128/64 R1.1 providing security functions as required in Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8] (Generic Security Target). Threats on the overall Tachograph System which are not related to the Tachograph Smart Cards were not addressed by this product evaluation. 5 Architectural Information The TOE is a product. It is composed from an Integrated Circuit (IC) with its proprietary IC Dedicated Software and a Smart Card Embedded Software (ES), consisting of Basic Software (BS) and Application Software (AS). The Design of the Embedded Software is based on the Java Card Platform Version 2.1.1 with a dedicated Java Card Applet for the Tachograph Card application. The four different card types are distinguished as they contain a specific applet each, and specific data structures and data. As all parts of TOE software are running inside the IC, the external interface of the TOE to its environment can be defined as the external interface of this IC, the Philips P16WX064V0C Secure 16-bit Smart Card Controller. The external interface is divided into a physical / electrical interface and a logical interface. The physical / electrical interface of the P16WX064V0C are the pads to connect the lines supply voltage, reset input, clock input, ground and I/O. An external voltage and timing supply as well as a data interface are necessary for the operation of the IC. Beyond the physical behaviour, the data interface is defined by the Smart Card Embedded Software (ES). A user would use the physical interface via the Chip card contacts. The electrical and physical characteristics fulfilled are given in the Tachograph Cards Specification [8]. The location and B-17 Certification Report BSI-DSZ-CC-0267-2004 dimensions of the Chip card contacts comply with the ISO/IEC 7816-2. The electronic signals, the working of the card as well as the power consumption are in accordance with ISO/IEC 7816. The logical interface consists of two parts: (i) everything below the command level and (ii) the accessing of the Tachograph Cards by commands via the command interface. Commands and protocols of the Tachograph Application for phase 7 are fully described in the Tachograph Cards Specification [8] with the exception of one newly introduced command, “GET DATA” which does not read any security relevant data. Specific commands for the personalisation phase (phase 6) are described in the User Guidance for the Personaliser [15]. The subsystems of the TOE are described in the ST [7], chapter 2.1. The TOE Summary Specification (chapter 6 of the ST [7]) describes the TOE Security Functions with relation to the IC and Cryptographic Library and to the Embedded Software. 6 Documentation The user of the TOE is (i) the developer of a vehicle unit who needs information how the TOE interacts with the vehicle unit (ii) the personaliser of the Tachograph Cards who needs information about security procedures and how the TOE supports the personalisation process (iii) the issuer of the Tachograph Cards who needs information how to use the 4 different card types after personalisation, information on specific aspects of the issuance of the Tachograph Cards and information to be passed to the end-user of the Tachograph Cards (card-holder, e.g. the driver). For these three types of users separate user documentation is provided (see [15], [16] and [17]). Additionally, the Tachograph Card Version 1.1 128/64 R1.1, Data Sheet [20] is provided by ORGA. It contains Answer To Reset (ATR) information and File Control Information (FCI) as identification information for the Tachograph Cards. As some data contained in the Data Sheet can be customer specific, it will be provided individually for specific customers. 7 IT Product Testing Tests of the TOE were done (i) with real cards using a card reader and a PC and (ii) in an emulator test environment. For those tests, where real cards are used, the specified method was used to identify the Tachograph Card version and the correct card configuration for every test. The real cards used for testing were either in initialised state (i. e. B-18 BSI-DSZ-CC-0267-2004 Certification Report ready for personalisation) or in operational state (i. e. personalisation com- pleted). Using specific commands for reading FCI-data, the life cycle state of the applet and the type of the card could be determined. For identification of the correct versions of the electronic data used for tests in the emulator test environment, and to determine whether the initial condition of each test is satisfied, the methods of the evaluated Configuration Management System were used. The version control mechanism can guarantee that the design files and the initial data used for testing are those provided by the developers for the specific version of the TOE under evaluation. As specific subsystems are the same in all card types and others are different, some tests had to be performed on all four card types, others could be re-used. Tests after modifications of the TOE during the evaluation process were re- done as necessary depending on the specific change. For re-evaluation, a subset of the developer and independent evaluator tests of BSI-DSZ-CC-0205-2003 had to be repeated. Especially tests covering product changes were performed again. Developer tests: For developer tests, the test cases were mapped to Security Functions. All Security Functions with their security properties and their interfaces were covered. In addition, the test cases were mapped to subsystems of the High- Level Design and to modules of the Low-Level Design. All subsystems and modules with their security properties and their interfaces were covered. The developer tested each property of the design specification. All command APDU with valid and invalid inputs are tested and all functions are tested with valid and invalid inputs. All test results were documented in log-files. All security functions were tested with overall positive results. Independent evaluator tests: Most tests of the evaluator were done by ISO-7816 APDU command sequences using a real card. Tests with emulators were chosen by the evaluators only for those security functions, where internal resources of the card needed to be modified or observed during the test (e.g. Anti-DPA-Measures and Residual Information protection). Several issues have been checked extensively by functional tests and by source code analysis (e.g. I/O-testing, making sure that the protocol levels of the TOE interface below ISO command level have stable behaviour; functional Tachograph command testing including all possible error cases showing that no undesired behaviour exits on command level which might be exploitable by an attacker). Side channel attacks on DES and RSA were tested and analysed during the evaluation of BSI-DSZ-CC-0205-2003. The result of these analysis is still valid. It showed that secret keys could not be extracted. In addition, tests according to Appendix 9 of the EU Tachograph Card Commis- sion Regulation [8] have been performed. Preliminary, the personalisation B-19 Certification Report BSI-DSZ-CC-0267-2004 process of the cards has been carried out and thereby tested. The tests have been performed for all four different types of ORGA Tachograph Cards. For the Appendix 9 tests, cards with the final ROM mask and the actual Tachograph Applet have been used. The achieved test results correspond to the expected test results (see Annex A of this report). 8 Evaluated Configuration The TOE is delivered within or at the end of phase 5 in form of initialised and tested complete cards or in form of initialised and tested modules (see table 1). A Tachograph Card may be of the following types: Driver Card, Control Card, Workshop Card or Company Card depending on the specific applet and data loaded into the card. Additionally, a General Tachograph Card is available that can be irreversibly converted into one of the different card types by using a specific card command after initialisation resp. prior to the personalisation of the card. These five different card types are considered as different configurations of the TOE. All procedures for personalisation and configuration for the end-user necessary after delivery are described in the user documentation [15]. 9 Results of the Re-Evaluation The Evaluation Technical Report (ETR) [11] was provided by the ITSEF SRC Security Research & Consulting GmbH 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. As the evaluation of the TOE was conducted as a composition evaluation, the ETR [11] includes also the evaluation results of the composite evaluation activi- ties in accordance with CC Supporting Document, ETR-lite for Composition: Annex A Composite smart card evaluation [4, AIS 36]. The ETR [11] builds up on the ETR-lite for Composition documents of the evaluations of the underlying „Philips P16WX064V0C Secure 16-bit Smart Card Controller“ and of the underlying „Philips P16WX064V0C Secure 16-bit Smart Card Controller with Caernarvon Cryptographic Library on Philips Smart XA2 as IC Dedicated Support Software". These ETR-lite for Composition documents were provided by the ITSEF T-Systems GEI GmbH according to CC Supporting Document, ETR-lite for Composition ([4, AIS 36]). The evaluation methodology CEM [2] was used for those components identical with EAL4. For components beyond EAL4 the methodology was defined in co- ordination with the Certification Body. For smart card specific methodology the scheme interpretations AIS 25, AIS 26 and AIS 36 (see [4]) were used. For specific methodology on random number generator evaluation the scheme interpretations AIS 20 and AIS 31 (see [4]) were used.

Therefore the scheme interpretations AIS 20, AIS 26 and AIS 31 (see [4]) were used. The rating of the strength of functions does not include the cryptoalgorithms suitable for encryption and decryption (see BSIG Section 4, Para. 3, Clause 2). · specific tests required by Appendix 9 of the EU Tachograph Card Commission Regulation [8] are fulfilled (see Annex A of this report). The underlying hardware had been successfully reassessed by T-Systems GEI GmbH. The results of the evaluation are only applicable to the Tachograph Card Version 1.1 128/64 R1.1. The validity can be extended to new versions and releases of the product, provided the sponsor applies for re-certification of the modified product, in accordance with the procedural requirements, and the evaluation of the modified product does not reveal any security deficiencies. B-22 BSI-DSZ-CC-0267-2004 Certification Report 10 Comments/Recommendations The User Guidance documentation (refer to chapter 6) contains necessary information about the secure usage of the TOE. Additionally, for secure usage of the TOE the fulfilment of the assumptions about the environment in the Security Target [7] and the Security Target as a whole has to be taken into account. Therefore a user/administrator has to follow the guidance in these documents. 11 Annexes none 12 Security Target For the purpose of publishing, the Security Target [7] of the Target of Evaluation (TOE) is provided within a separate document.

The CC approach identifies the separate concepts of assurance in a TOE at the end of the evaluation, and of maintenance of that assurance during the operational use of the TOE. It is important to note that not all families and components from Part 3 are included in the EALs. This is not to say that these do not provide meaningful and desirable assurances. Instead, it is expected that these families and components will be considered for augmentation of an EAL in those PPs and STs for which they provide utility. Evaluation assurance level (EAL) overview (chapter 6.1) Table 6.1 represents a summary of the EALs. The columns represent a hierarchically ordered set of EALs, while the rows represent assurance families. Each number in the resulting matrix identifies a specific assurance component where applicable. As outlined in the next section, seven hierarchically ordered evaluation assurance levels are defined in the CC for the rating of a TOE's assurance. They are hierarchically ordered inasmuch as each EAL represents more assurance than all lower EALs. The increase in assurance from EAL to EAL is accomplished by substitution of a hierarchically higher assurance component from the same assurance family (i.e. increasing rigour, scope, and/or depth) and from the addition of assurance components from other assurance families (i.e. adding new requirements). These EALs consist of an appropriate combination of assurance components as described in chapter 2 of this Part 3. More precisely, each EAL includes no more than one component of each assurance family and all assurance dependencies of every component are addressed. While the EALs are defined in the CC, it is possible to represent other combinations of assurance. Specifically, the notion of “augmentation“ allows the addition of assurance components (from assurance families not already included in the EAL) or the substitution of assurance components (with another hierarchically higher assurance component in the same assurance family) to an EAL. Of the assurance constructs defined in the CC, only EALs may be augmented. The notion of an “EAL minus a constituent assurance component“ is not recognised by the CC as a valid claim. Augmentation carries with it the obligation on the part of the claimant to justify the utility and added value of the added assurance component to the EAL. An EAL may also be extended with explicitly stated assurance requirements.

It will be of value where independent assurance is required to support the contention that due care has been exercised with respect to the protection of personal or similar information. EAL1 provides an evaluation of the TOE as made available to the customer, including independent testing against a specification, and an examination of the guidance documentation provided. It is intended that an EAL1 evaluation could be successfully conducted without assistance from the developer of the TOE, and for minimal outlay. An evaluation at this level should provide evidence that the TOE functions in a manner consistent with its documentation, and that it provides useful protection against identified threats.“ Evaluation assurance level 2 (EAL2) - structurally tested (chapter 6.2.2) „Objectives EAL2 requires the co-operation of the developer in terms of the delivery of design information and test results, but should not demand more effort on the part of the developer than is consistent with good commercial practice. As such it should not require a substantially increased investment of cost or time. EAL2 is therefore applicable in those circumstances where developers or users require a low to moderate level of independently assured security in the absence of ready availability of the complete development record. Such a situation may arise when securing legacy systems, or where access to the developer may be limited.“ Evaluation assurance level 3 (EAL3) - methodically tested and checked (chapter 6.2.3) „Objectives EAL3 permits a conscientious developer to gain maximum assurance from positive security engineering at the design stage without substantial alteration of existing sound development practices. EAL3 is applicable in those circumstances where developers or users require a moderate level of independently assured security, and require a thorough investigation of the TOE and its development without substantial re-engineering.“ Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed (chapter 6.2.4) „Objectives EAL4 permits a developer to gain maximum assurance from positive security engineering based on good commercial development practices which, though rigorous, C-5 Certification Report BSI-DSZ-CC-0267-2004 do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. EAL4 is therefore applicable in those circumstances where developers or users require a moderate to high level of independently assured security in conventional commodity TOEs and are prepared to incur additional security-specific engineering costs.“ Evaluation assurance level 5 (EAL5) - semiformally designed and tested (chapter 6.2.5) „Objectives EAL5 permits a developer to gain maximum assurance from security engineering based upon rigorous commercial development practices supported by moderate application of specialist security engineering techniques. Such a TOE will probably be designed and developed with the intent of achieving EAL5 assurance. It is likely that the additional costs attributable to the EAL5 requirements, relative to rigorous development without the application of specialised techniques, will not be large. EAL5 is therefore applicable in those circumstances where developers or users require a high level of independently assured security in a planned development and require a rigorous development approach without incurring unreasonable costs attributable to specialist security engineering techniques.“ Evaluation assurance level 6 (EAL6) - semiformally verified design and tested (chapter 6.2.6) „Objectives EAL6 permits developers to gain high assurance from application of security engineering techniques to a rigorous development environment in order to produce a premium TOE for protecting high value assets against significant risks. EAL6 is therefore applicable to the development of security TOEs for application in high risk situations where the value of the protected assets justifies the additional costs.“ Evaluation assurance level 7 (EAL7) - formally verified design and tested (chapter 6.2.7) „Objectives EAL7 is applicable to the development of security TOEs for application in extremely high risk situations and/or where the high value of the assets justifies the higher costs. Practical application of EAL7 is currently limited to TOEs with tightly focused security functionality that is amenable to extensive formal analysis.“ C-6 BSI-DSZ-CC-0267-2004 Certification Report Strength of TOE security functions (AVA_SOF) (chapter 14.3) AVA_SOF Strength of TOE security functions „Objectives Even if a TOE security function cannot be bypassed, deactivated, or corrupted, it may still be possible to defeat it because there is a vulnerability in the concept of its underlying security mechanisms. For those functions a qualification of their security behaviour can be made using the results of a quantitative or statistical analysis of the security behaviour of these mechanisms and the effort required to overcome them. The qualification is made in the form of a strength of TOE security function claim.“ Vulnerability analysis (AVA_VLA) (chapter 14.4) AVA_VLA Vulnerability analysis „Objectives Vulnerability analysis is an assessment to determine whether vulnerabilities identified, during the evaluation of the construction and anticipated operation of the TOE or by other methods (e.g. by flaw hypotheses), could allow users to violate the TSP. Vulnerability analysis deals with the threats that a user will be able to discover flaws that will allow unauthorised access to resources (e.g. data), allow the ability to interfere with or alter the TSF, or interfere with the authorised capabilities of other users.“ „Application notes A vulnerability analysis is performed by the developer in order to ascertain the presence of security vulnerabilities, and should consider at least the contents of all the TOE deliverables including the ST for the targeted evaluation assurance level. The developer is required to document the disposition of identified vulnerabilities to allow the evaluator to make use of that information if it is found useful as a support for the evaluator's independent vulnerability analysis.“ „Independent vulnerability analysis goes beyond the vulnerabilities identified by the developer. The main intent of the evaluator analysis is to determine that the TOE is resistant to penetration attacks performed by an attacker possessing a low (for AVA_VLA.2), moderate (for AVA_VLA.3) or high (for AVA_VLA.4) attack potential.“ C-7 Certification Report BSI-DSZ-CC-0267-2004 This page is intentionally left blank.
