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 ISO documents 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 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

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: www.iso.org/iso/foreword.html.
This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 27, IT Security techniques.
This second edition cancels and replaces the first edition (ISO/IEC 27007:2011), which has been
technically revised.
The main changes compared to the previous edition are as follows:

5.1.1 IS 5.1 General
1)
An organization needing to conduct audits should establish the audit programme, taking account of
the risks and opportunities determined when planning the ISMS.
5.2 Establishing the audit programme objectives
The guidelines of ISO 19011:2011, 5.2 apply. In addition, the following guidance applies.

be found in ISO/IEC 27004.
d) risks and opportunities determined when planning the ISMS of the auditee;
e) information security risks to the relevant parties, i.e. the auditee and audit client.
Examples of ISMS-specific audit programme objectives include:
— verification of conformity with the relevant legal and contractual requirements and other
requirements and their security implications;
— obtaining and maintaining confidence in the risk management capability of the auditee;
— evaluating the effectiveness of the actions to address information security risks and opportunities.
5.3 Establishing the audit programme

1) the total number of persons doing work under the organization's control and relationships
with interested parties and contractors that are relevant to the ISMS;
1) For the purpose of this document, the term “audit” refers to ISMS audits.

2) the number of information systems;
3) the number of sites covered by the ISMS;
b) the complexity of the ISMS (including the number and criticality of processes and activities) taking
into account differences between sites within the ISMS scope;
c) the significance of the information security risks identified for the ISMS in relation to the business;
d) the significance of the risks and opportunities determined when planning the ISMS;
e) the importance of preserving the confidentiality, integrity and availability of information within
the scope of the ISMS;
f) the complexity of the information systems to be audited, including complexity of information
technology deployed;
g) the number of similar sites.
Consideration should be given in the audit programme to setting priorities that warrant more detailed
examination based on the significance of information security risks and business requirements in
respect to the scope of the ISMS.
NOTE Further information about determining audit time can be found in ISO/IEC 27006. Further information
on multi-site sampling can be found in ISO/IEC 27006 and mandatory document 1 from the International

5.4.2.1 IS 5.4.2 Defining the objectives, scope and criteria for an individual audit
The audit objectives can include the following:
a) evaluation of whether the ISMS adequately identifies and addresses information security
requirements;
b) evaluation of the processes for the maintenance and effective improvement of the ISMS;
c) determination of the extent of conformity of information security controls with the requirements
and procedures of the ISMS.
The audit scope should take into account information security risks and relevant risks and opportunities
affecting the ISMS of relevant parties, i.e. the audit client and the auditee.
If ISMS is in the scope of the audit, then the audit team should verify that the scope and boundaries of the
ISMS of the auditee are clearly defined based on internal and external issues and the needs and expectations
of interested parties. The audit team should confirm that the auditee addresses the requirements stated
in ISO/IEC 27001:2013, 4.3 within the scope of the ISMS, as relevant to the audit scope.
The following topics can be considered as audit criteria and used as a reference against which
conformity is determined:
a) the information security policy, information security objectives, policies and procedures adopted
by the auditee;
b) legal and contractual requirements and other requirements relevant to the auditee;
c) the auditee's information security risk criteria, information security risk assessment process and
risk treatment process;
d) the Statement of Applicability, the identification of any sector-specific or other necessary controls,
justification for inclusions, whether they are implemented or not and the justification for exclusions
of controls of ISO/IEC 27001:2013, Annex A;
e) the definition of controls to treat risks appropriately;
f) the methods and criteria for monitoring, measurement, analysis and evaluation of the information
security performance and the effectiveness of the ISMS;
