The CPE applicability language specification is part of a stack o

8、f CPE specifications that support a variety of use cases relating to IT product description and naming. The CPE applicability language data model builds on top of other CPE specifications to provide the functionality required to allow CPE users to construct complex groupings of CPE names to describe

9、 IT platforms. These groupings are referred to as applicability statements because they are used to designate the platforms to which particular guidance, policies, etc. apply. This Recommendation defines the semantics of the CPE applicability language data model and the requirements that IT products

10、 and CPE applicability language documents must meet to claim compliance with this Recommendation. This is achieved by listing the relevant clauses of the NIST Interagency Report 7698: Common Platform Enumeration Applicability Language Specification version 2.3 and showing whether they are normative

11、or informative. History Edition Recommendation Approval Study Group 1.0 ITU-T X.1528.4 2012-09-07 17 ii Rec. ITU-T X.1528.4 (09/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication te

12、chnologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Tel

13、ecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some

14、areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized

15、operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “

16、shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the

17、 practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation d

18、evelopment process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are th

ITU-T X.1528.4 (09/2012) Introduction Common platform enumeration (CPE) is a stru

22、ctured method of describing and identifying classes of applications, operating systems, and hardware devices present in an enterprises computing assets. CPE can be used as a source of information for enforcing and verifying IT management policies relating to these assets, such as vulnerability, conf

23、iguration, and remediation policies. IT management tools can collect information about installed products, identify products using their CPE names, and use this structured information to help make fully or partially automated decisions regarding the assets. CPE consists of several modular specificat

24、ions. Combinations of the specifications work together in layers to perform various functions. One of these specifications, CPE applicability language, defines a structured way to describe IT platforms by forming complex logical expressions out of individual CPE names and references to checks. For e

25、xample, CPE applicability language could combine the CPE name for an operating system, the CPE name for an application running on that operating system, and a reference to a check for a particular value of a certain configuration setting (such as the wireless network card being enabled in the operat

26、ing system). These logical expressions are called applicability statements, because they are used to designate to which platforms particular guidance, policies, etc. apply. Applicability statements can be used by tools to determine whether a target system is an instance of a particular platform. The

27、 CPE names used by the CPE applicability language specification are bound forms of well-formed CPE names (WFNs), which are the abstract logical constructions for CPE names CPE23-N:5.1. The basic building block of the CPE applicability language specification is referred to as the logical test. This i

28、s a logical conjunction (AND) or disjunction (OR) of one or more CPE names and/or references to checks. Individual logical tests can also be negated (inverted). Nested logical tests allow the user to express a platform as any logical combination of individual CPE names and/or references to checks. N

29、ote that previous NIST versions of CPE referred to the Applicability Language specification as simply the language specification. Rec. ITU-T X.1528.4 (09/2012) 1 Recommendation ITU-T X.1528.4 Common platform enumeration applicability language 1 Scope This Recommendation defines the specification for

30、 CPE applicability language. The Recommendation also defines and explains the requirements that producers of CPE applicability language-supporting implementations, such as software and services, and CPE applicability language content must meet to claim compliance with this Recommendation. As this Re

31、commendation defines these specifications by listing the relevant clauses of the NIST Interagency Report 7698 Common Platform Enumeration: Applicability Language specification version 2.3 and showing whether they are normative or informative, all other versions are out of the scope of this Recommend

32、ation as are all CPE specifications other than CPE applicability language. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated

33、were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below.
