9、tional bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual intere
10、st. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with t
11、he rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requir

25、002/1000/11830-en. ii Rec. ITU-T X.1631 (07/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU TelecommunicationStandardization Sector (ITU-T) is a perm
26、anent organ of ITU. ITU-T is responsible for studying technical,operating and tariff questions and issuing Recommendations on them with a view to standardizingtelecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establish
27、esthe 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 areas of information technology which fall within ITU-Ts purview, the necessary standard
28、s areprepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both atelecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommend
29、ation may contain certainmandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with theRecommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some otherobligatory language such as “must“ and the negative equivalents are used
30、 to express requirements. The use ofsuch words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involvethe use of a claimed Intellectual
31、 Property Right. ITU takes no position concerning the evidence, validity orapplicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside ofthe Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice
32、 of intellectual property,protected by patents, which may be required to implement this Recommendation. However, implementers arecautioned that this may not represent the latest information and are therefore strongly urged to consult the TSBpatent database at http:/www.itu.int/ITU-T/ipr/. ITU 2015 A

Specifically, this Re
43、commendation | International Standard provides guidelines supporting the implementation ofinformation security controls for cloud service customers and cloud service providers. Some guidelines are for cloudservice customers who implement the controls, and others are for cloud service providers to su
44、pport the implementationof those controls. The selection of appropriate information security controls and the application of the implementationguidance provided, will depend on a risk assessment and any legal, contractual, regulatory or other cloud-sector specificinformation security requirements.
