Introduction

An information security management system (ISMS) audit can be conducted against a range of audit

criteria, separately or in combination, including but not limited to:
— requirements defined in ISO/IEC 27001:2013;
— policies and requirements specified by relevant interested parties;
— statutory and regulatory requirements;
— ISMS processes and controls defined by the organization or other parties;

— management system plan(s) relating to the provision of specific outputs of an ISMS (e.g. plans to

address risks and opportunities when establishing ISMS, plans to achieve information security

objectives, risk treatment plans, project plans).

This document provides guidance for all sizes and types of organizations and ISMS audits of varying

scopes and scales, including those conducted by large audit teams, typically of larger organizations, and

those by single auditors, whether in large or small organizations. This guidance should be adapted as

appropriate to the scope, complexity and scale of the ISMS audit programme.

This document concentrates on ISMS internal audits (first party) and ISMS audits conducted by

organizations on their external providers and other external interested parties (second party). This

document can also be useful for ISMS external audits conducted for purposes other than third party

management system certification. ISO/IEC 27006 provides requirements for auditing ISMS for third

party certification; this document can provide useful additional guidance.

This document is to be used in conjunction with the guidance contained in ISO 19011:2018.

This document follows the structure of ISO 19011:2018.

ISO 19011:2018 provides guidance on the management of audit programmes, the conduct of internal or

external audits of management systems, as well as on the competence and evaluation of management

system auditors.

Annex A provides guidance for ISMS auditing practices along with requirements of ISO/IEC 27001:2013,

Clauses 4 to 10.

d) information security risks to the relevant parties, i.e. the auditee and audit client.

Examples of ISMS-specific audit programme objectives include:

— demonstrate conformity with all relevant legal and contractual requirements and other requirements

and their security implications;

— obtain and maintain confidence in the risk management capability of the auditee;

— evaluate the effectiveness of the actions to address information security risks and opportunities.

5.3 Determining and evaluating audit programme risks and opportunities
5.3.1 The guidelines of ISO 19011:2018, 5.3, apply.

5.3.2 Measures to ensure information security and confidentiality should be determined considering

auditees and other relevant party requirements. Other party requirements can include relevant legal and

contractual requirements.
5.4 Establishing audit programme
5.4.1 Roles and responsibilities of the individual(s) managing audit programme

The guidelines of ISO 19011:2018, 5.4.1, apply. In addition, the guidance in 5.4.1.2 applies.

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

Introduction

An information security management system (ISMS) audit can be conducted against a range of audit

criteria, separately or in combination, including but not limited to:
— requirements defined in ISO/IEC 27001:2013;
— policies and requirements specified by relevant interested parties;
— statutory and regulatory requirements;
— ISMS processes and controls defined by the organization or other parties;

— management system plan(s) relating to the provision of specific outputs of an ISMS (e.g. plans to

address risks and opportunities when establishing ISMS, plans to achieve information security

objectives, risk treatment plans, project plans).

This document provides guidance for all sizes and types of organizations and ISMS audits of varying

scopes and scales, including those conducted by large audit teams, typically of larger organizations, and

those by single auditors, whether in large or small organizations. This guidance should be adapted as

appropriate to the scope, complexity and scale of the ISMS audit programme.

This document concentrates on ISMS internal audits (first party) and ISMS audits conducted by

organizations on their external providers and other external interested parties (second party). This

document can also be useful for ISMS external audits conducted for purposes other than third party

management system certification. ISO/IEC 27006 provides requirements for auditing ISMS for third

party certification; this document can provide useful additional guidance.

This document is to be used in conjunction with the guidance contained in ISO 19011:2018.

This document follows the structure of ISO 19011:2018.

ISO 19011:2018 provides guidance on the management of audit programmes, the conduct of internal or

external audits of management systems, as well as on the competence and evaluation of management

system auditors.

Annex A provides guidance for ISMS auditing practices along with requirements of ISO/IEC 27001:2013,

Clauses 4 to 10.
