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).

Introduction

An information security management system (ISMS) includes a collection of interacting processes and is operated by performing those processes. This document provides a process reference model (PRM) for information security management, which differentiates between ISMS processes and measures/controls initiated by them.

A PRM is a model comprising definitions of processes described in terms of process purpose and results, together with an architecture describing the relationships between the processes. Using the PRM in a practical application can require additional elements suited to the environment and circumstances.

The PRM specified in this document describes the ISMS processes implied by ISO/IEC 27001. The PRM is intended to be used as a process implementation and operation guide.

Any organization can define processes with additional elements in order to tailor it to its specific environment and circumstances. Some processes cover general management aspects of an organization. These processes have been identified in order to support organizations in addressing the requirements of ISO/IEC 27001.

1 Scope

This document defines a process reference model (PRM) for the domain of information security management, which is meeting the criteria defined in ISO/IEC 33004 for process reference models (see Annex A). It is intended to guide users of ISO/IEC 27001 to:

incorporate the process approach as described by ISO/IEC 27000:2018, 4.3, within the ISMS;
be aligned to all the work done within other standards of the ISO/IEC 27000 family from the perspective of the operation of ISMS processes
support users in the operation of an ISMS – this document is complementing the requirements-oriented perspective of ISO/IEC 27003 with an operational, process-oriented point of view.
