Foreword This ETSI Standard (ES) has been produced by ETSI Technical

14、 Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The present document has been prepared with the sponsorship of the eEurope programme as part of the ETSI support to the eEurope action line for a secure information infrastructu

15、re (item 3: Society). A major part of any security specification, and of a security product, is the measure of assurance it provides with respect to the security it offers. Information security evaluation contributes to the users trust and confidence in communications products and services. The use

16、of common criteria for evaluation (as defined in ISO/IEC 15408 7) has facilitated mutual recognition of results in many European countries and these countries have also entered into an arrangement with the US and Canada for further mutual recognition of IT security certificates. The present document

17、 is part of a set of standards and guidelines which show how the Common Criteria as identified in ISO/IEC 15408 7 can be used effectively within the ETSI standardization process. The documents in this set are: EG 202 387 1: Method for application of Common Criteria to ETSI deliverables; ES 202 382:

18、Method and proforma for defining Protection Profiles; ES 202 383 2: Method and proforma for defining Security Targets. Between them, these documents identify how standards fit to the Common Criteria and how developers of standards should prepare their standards with a view to support submission for

19、evaluation of product conforming to the standards. Adoption of Common Criteria objectives in standardization of security countermeasures is also consistent with achieving the objectives and recommendations of the NIS report. ETSI ETSI ES 202 382 V1.1.1 (2005-04) 5 1 Scope The present document provid

20、es guidance on the preparation of Protection Profiles (PP) based upon ETSI communication standards. A PP defines an implementation-independent set of security requirements for a category of communications equipment which is subject to evaluation under the Common Criteria (CC) scheme described in the

21、 multipart ISO/IEC 15408 7.The detailed contents of a PP are specified in ISO/IEC 15408-1 4. The use and applicability of the CC to the ETSI standardization process is described in EG 202 387 1 and further guidance on the implementation of security-related standards in telecommunications equipment i

22、s specified in ES 202 383 2. Throughout the present document, a worked example of a Protection Profile (PP) for TETRA Direct Mode Operation (DMO) security is used as an illustration. A partially complete PP for TETRA DMO security can be found in annex B. NOTE: TETRA DMO was chosen as the example in

23、the present document as, although the security analysis results, objectives and requirements are not necessarily collected together in one document, most of this information exists either explicitly or implicitly and it was, therefore, possible to construct a realistic and representative example PP.

24、 Conformance to the present document is established by successful evaluation to the requirements of ISO/IEC 15408-3 6. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identif

25、ied by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply.

31、valuation Assurance Level IT Information TechnologyMT Mobile Terminal PP Protection Profile TETRA TErrestrial Trunked RAdio TOE Target Of Evaluation 4 Overview 4.1 Common Criteria concepts The evaluation criteria for IT security, generally referred to as the “Common Criteria (CC)“, are defined in th

32、e multipart standard, ISO/IEC 15408 7 and are used as the basis for evaluation of security properties of IT products and systems. CC evaluation involves the preparation of a Protection Profile (PP) which is considered to be an implementation-independent set of IT security requirements for a category

33、 of equipment intended to meet common consumer needs for IT security. Communications standards are independent of any implementation and, thus, those specifying security requirements can be considered to be PPs. Once published, such a PP could be used without modification to specify the security req

34、uirements of a specific product or service. Alternatively, it could be extended to include additional requirements where necessary. ISO/IEC 15408-3 6 makes provision for a PP to be evaluated under the requirements of the common criteria and it is for this purpose that the PP proforma in the present

35、document has been specified. 4.2 Relationship between a standard and a PP The information and the requirements expressed in a security-related standard are very similar to those that are expected to be found in a PP. However, because a standard is intended to be the basis for implementation whereas

36、the intended purpose of a PP is to be the basis for evaluation, the presentation and emphasis of the contents is necessarily different in each. The PP proforma for communications standards (annex A), therefore, summarizes the content of the standard in a form that is acceptable as a PP and provides

37、references to clauses where more detailed information can be found. It is essential that the references to clauses in the base security standard and the Vulnerability Analysis are accurately maintained. To simplify this maintenance, both the PP proforma and the Vulnerability Analysis should be inclu

38、ded either as annexes to the base security standard or, where the present document is extensive, as distinct parts of a multi-part document set.

41、troduction 5.1.1.1 PP identification A PP is required to provide enough labelling and descriptive information to enable it to be identified, catalogued, registered and cross referenced. The document number, version, date and full title of an ETSI standard are sufficient for this purpose and should b

42、e used. EXAMPLE: Introduction Doc No. EN 300 396-6 Version V1.2.1 Date 2004-05 Full Title Terrestrial Trunked Radio (TETRA); Direct Mode Operation (DMO); Part 6: Security 5.1.1.2 PP overview A PP should include a narrative summary as part of the Introduction 4. The purpose of this is to provide enou

43、gh information that a potential user can make an informed decision on whether the PP is likely to be of interest. A fully specified Scope clause from an ETSI standard meets this requirement and should be used. EXAMPLE: Introduction Doc No. EN 300 396-6 Version V1.2.1 Date 2004-05 Full Title Terrestr

44、ial Trunked Radio (TETRA); Direct Mode Operation (DMO); Part 6: Security Overview The present document defines the Terrestrial Trunked Radio system (TETRA) Direct Mode of operation. It specifies the basic Air Interface (AI), the interworking between Direct Mode Groups via Repeaters and interworking

45、with the TETRA Trunked system via Gateways. It also specifies the security aspects in TETRA Direct Mode and the intrinsic services that are supported in addition to the basic bearer and teleservices. The present document describes the security mechanisms in TETRA Direct Mode. It provides mechanisms

46、for confidentiality of control signalling and user speech and data at the AI. It also provided some implicit authentication as a member of a group by knowledge of a shared secret encryption key. The use of AI encryption gives both confidentiality protection against eavesdropping, and some implicit a

47、uthentication. 5.1.2 Target Of Evaluation description NOTE 1: Throughout the present document, the term “Target Of Evaluation (TOE)“ is used to identify any product which implements the technical requirements of the standard(s) associated with a particular PP. ISO/IEC 15408-1 4 requires that a brief

48、 but clear description of the Target Of Evaluation (TOE) should be included in a PP. While not expressing the security requirements in detail, this should make the security aspects of the standard clear. If the standard includes a short clause entitled “General Description“ (or something similar) ea

49、rly in the document, it is likely that this text will be adequate as the TOE description. In the event that such a clause does not exist it will need to be written for the PP and should include the following: identification of the type of product that is likely to implement the standard; NOTE 2: In the context of the present document, the term “product“ should be interpreted in its widest sense to include all types of communications equipment as well as services. general summary of the communications features specifie
