22、Cloud service providers who process Personally Identifiable Information (PII) under contract to their customers have to operate their services in ways that allow both parties to meet the requirements of applicable legislation and regulations covering the protection of PII. The requirements and the w

23、ay in which the requirements are divided between the cloud service provider and its customers vary according to legal jurisdiction, and according to the terms of the contract between the cloud service provider and the customer. Legislation which governs how PII is allowed to be processed (i.e. colle

24、cted, used, transferred and disposed of) is sometimes referred to as data protection legislation; PII is sometimes referred to as personal data or personal information. The obligations falling on a PII processor vary from jurisdiction to jurisdiction, which makes it challenging for businesses provid

25、ing cloud computing services to operate multinationally. A public cloud service provider is a PII processor when it processes PII for and according to the instructions of a cloud service customer. The cloud service customer, who has the contractual relationship with the public cloud PII processor, c

26、an range from a natural person, a PII principal, processing his or her own PII in the cloud, to an organization, a PII controller, processing PII relating to many PII principals. The cloud service customer might authorize one or more cloud service users associated with it to use the services made av

27、ailable to it under its contract with the public cloud PII processor. Note that the cloud service customer has authority over the processing and use of the data. A cloud service customer who is also a PII controller might be subject to a wider set of obligations governing the protection of PII than

28、the public cloud PII processor. Maintaining the distinction between PII controller and PII processor relies on the public cloud PII processor having no data processing objectives other than those set by the cloud service customer with respect to the PII it processes and the operations necessary to a

29、chieve the cloud service customers objectives. NOTE Where the public cloud PII processor is processing cloud service customer account data, it might be acting as a PII controller for this purpose. This International Standard does not cover such activity. The intention of this International Standard,

30、 when used in conjunction with the information security objectives and controls in ISO/IEC 27002, is to create a common set of security categories and controls that can be implemented by a public cloud computing service provider acting as a PII processor. It has the following objectives. To help the

31、 public cloud service provider to comply with applicable obligations when acting as a PII processor, whether such obligations fall on the PII processor directly or through contract. To enable the public cloud PII processor to be transparent in relevant matters so that cloud service customers can sel

32、ect well-governed cloud-based PII processing services. To assist the cloud service customer and the public cloud PII processor in entering into a contractual agreement. To provide cloud service customers with a mechanism for exercising audit and compliance rights and responsibilities in cases where

33、individual cloud service customer audits of data hosted in a multi-party, virtualized server (cloud) environment might be impractical technically and might increase risks to those physical and logical network security controls in place. This International Standard does not replace applicable legisla

34、tion and regulations, but can assist by providing a common compliance framework for public cloud service providers, in particular those that operate in a multinational market. 0.2 PII protection controls for public cloud computing services This International Standard is designed for organizations to

35、 use as a reference for selecting PII protection controls within the process of implementing a cloud computing information security management system based on ISO/IEC 27001, or as a guidance document for implementing commonly accepted PII protection controls for organizations acting as public cloud

36、PII processors. In particular, vi ISO/IEC 2014 All rights reservedBS ISO/IEC 27018:2014ISO/IEC 27018:2014(E) this International Standard has been based on ISO/IEC 27002, taking into consideration the specific risk environment(s) arising from those PII protection requirements which might apply to pub

37、lic cloud computing service providers acting as PII processors. Typically an organization implementing ISO/IEC 27001 is protecting its own information assets. However, in the context of PII protection requirements for a public cloud service provider acting as a PII processor, the organization is pro

38、tecting the information assets entrusted to it by its customers. Implementation of the controls of ISO/IEC 27002 by the public cloud PII processor is both suitable for this purpose and necessary. This International Standard augments the ISO/IEC 27002 controls to accommodate the distributed nature of

39、 the risk and the existence of a contractual relationship between the cloud service customer and the public cloud PII processor. This International Standard augments ISO/IEC 27002 in two ways: implementation guidance applicable to public cloud PII protection is provided for certain of the existing I

40、SO/IEC 27002 controls, and Annex A provides a set of additional controls and associated guidance intended to address public cloud PII protection requirements not addressed by the existing ISO/IEC 27002 control set. Most of the controls and guidance in this International Standard will also apply to a

41、 PII controller. However, the PII controller will, in most cases, be subject to additional obligations not specified here. 0.3 PII protection requirements It is essential that an organization identifies its requirements for the protection of PII. There are three main sources of requirement, as given

42、 below. a) Legal, Statutory, Regulatory and Contractual Requirements: One source is the legal, statutory, regulatory and contractual requirements and obligations that an organization, its trading partners, contractors and service providers have to satisfy, and their socio-cultural responsibilities a

43、nd operating environment. It should be noted that legislation, regulations and contractual commitments made by the PII processor might mandate the selection of particular controls and might also necessitate specific criteria for implementing those controls. These requirements can vary from one juris

44、diction to another. b) Risks: Another source is derived from assessing risks to the organization associated with PII, taking into account the organizations overall business strategy and objectives. Through a risk assessment, threats are identified, vulnerability to and likelihood of occurrence is ev

45、aluated and potential impact is estimated. ISO/IEC 27005 provides information security risk management guidance, including advice on risk assessment, risk acceptance, risk communication, risk monitoring and risk review. ISO/IEC 29134 provides guidance on privacy impact assessment. c) Corporate polic

46、ies: While many aspects covered by a corporate policy are derived from legal and socio-cultural obligations, an organization might also choose voluntarily to go beyond the criteria that are derived from the requirements of a). 0.4 Selecting and implementing controls in a cloud computing environment

47、Controls can be selected from this International Standard (which includes by reference the controls from ISO/IEC 27002, creating a combined reference control set for the sector or application defined by the scope). If required, controls can also be selected from other control sets, or new controls c

48、an be designed to meet specific needs as appropriate. NOTE A PII processing service provided by a public cloud PII processor could be considered as an application of cloud computing rather than as a sector in itself. Nevertheless, the term sector-specific is used in this International Standard, as t

49、his is the conventional term used within other standards in the ISO/IEC 27000 series. The selection of controls is dependent upon organizational decisions based on the criteria for risk acceptance, risk treatment options, and the general risk management approach applied to the organization and, through contractual agreements, its customers and suppliers, and will also be subject to all relevant ISO/IEC 2014 All rights reserved viiBS ISO/IEC 27018:2014ISO/IEC 27018:2014(E) national and international legislation and regulatio
