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. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
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) see the following
URL: w w w . i s o .org/ iso/ foreword .html.
This document was prepared by ISO/IEC JTC 1, Information technology, Subcommittee SC 27, IT Security
techniques.
This second edition of ISO/IEC 27003 cancels and replaces the first edition (ISO/IEC 27003:2010), of
which it constitutes a minor revision.
The main changes compared to the previous edition are as follows:
— the scope and title have been changed to cover explanation of, and guidance on the requirements of,
ISO/IEC 27001:2013 rather than the previous edition (ISO/IEC 27001:2005);
— the structure is now aligned to the structure of ISO/IEC 27001:2013 to make it easier for the user to
use it together with ISO/IEC 27001:2013;
— the previous edition had a project approach with a sequence of activities. This edition instead
provides guidance on the requirements regardless of the order in which they are implemented.

Introduction
This document provides guidance on the requirements for an information security management system
(ISMS) as specified in ISO/IEC 27001 and provides recommendations (‘should’), possibilities (‘can’)
and permissions (‘may’) in relation to them. It is not the intention of this document to provide general
guidance on all aspects of information security.
Clauses 4 to 10 of this document mirror the structure of ISO/IEC 27001:2013.
This document does not add any new requirements for an ISMS and its related terms and definitions.
Organizations should refer to ISO/IEC 27001 and ISO/IEC 27000 for requirements and definitions.
Organizations implementing an ISMS are under no obligation to observe the guidance in this document.
An ISMS emphasizes the importance of the following phases:
— understanding the organization’s needs and the necessity for establishing information security
policy and information security objectives;
— assessing the organization’s risks related to information security;
— implementing and operating information security processes, controls and other measures to
treat risks;
— monitoring and reviewing the performance and effectiveness of the ISMS; and
— practising continual improvement.
An ISMS, similar to any other type of management system, includes the following key components:
a) policy;
b) persons with defined responsibilities;
c) management processes related to:
1) policy establishment;
2) awareness and competence provision;
3) planning;
4) implementation;
5) operation;
6) performance assessment;
7) management review; and
8) improvement; and
d) documented information.
An ISMS has additional key components such as:
