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, Part 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, Part 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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence
to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT)

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.
