Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National 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 interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, 1. In particular, the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ) or the IEC list of patent declarations received (see http://patents.iec.ch ).

Introduction

Many of the policies and practices in place for handling data in the cloud computing ecosystem need to be described based on the category of the data they address. For instance, personally identifiable information (PII) impose specific data management requirements not only in terms of security but also with regard to mechanisms that allow cloud service users to whom such data relate to exercise control on the usage and transfer of such data. Organisational data such as cloud service usage information and telemetry data from cloud services, which can be used for operational purposes such as improvement of service quality, may have to fulfil specific quality requirements to be useful for a given application.

Customer content data can be related to intellectual property rights and possibly needs appropriate protection by the cloud service provider (CSP). Certain data can be transferred from one jurisdiction to another. Depending on their data category, different instruments (multi-national laws, corporate binding rules, bilateral agreements) are applicable to enable such transfers.

When such policies and practices are to be described, it is helpful to do so in a structured and consistent way so that they can be better expressed, evaluated, analysed, and compared by the stakeholders in the cloud computing ecosystem. ISO/IEC 19944 provides a comprehensive taxonomy defining a fine-grained system of data categories that can be applied to various domains of policies for the handling of data in a cloud computing ecosystem such as cross border data transfer, data geolocation, data usage, data access and data portability, data management including data quality management and data security, or data governance, and provides guidelines on how to describe data handling policies and practices within codes of conduct (CoC).

This document describes such a structured and common approach to express any desired data handling policies and practices. It is important to emphasize that the policies and practices themselves are out of the scope of this document. This document describes a common structure and approach to express any desired data handling policies and practices. It is important to emphasize that the policies and practices are out of the scope of this document. A set of examples from data handling domains are provided in the document as guidance to understand how to use ISO/IEC 19944 regarding application of policies and analysis of policy requirements to such domains.

1 Scope

This document:

• describes a framework for the structured expression of data-related policies and practices in the cloud computing environment, based on the data taxonomy in ISO/IEC 19944;
• provides guidelines on application of the taxonomy for handling of data based on data subcategory and classification;
• covers expression of data-related policies and practices including, but not limited to data geolocation, cross border flow of data, data access and data portability, data use, data management, and data governance;
• describes how the framework can be used in codes of conduct for practices regarding data at rest and in transit, including cross border data transfer, as well as remote access to data;
• provides use cases for data handling challenges, i.e. control, access and location of data according to ISO/IEC 19944 data categories.

This document is applicable primarily to cloud service providers, cloud service customers (CSCs) and cloud service users, but also to any person or organization involved in legal, policy, technical or other implications of taxonomy-based data management in cloud services.
