Introduction
This document is related to ISO/SAE 21434 Road vehicles — Cybersecurity engineering and extends
ISO 19011 Guidelines for auditing management systems to the automotive domain.
This document is intended for organizations involved in automotive cybersecurity engineering in any
part of the automotive supply chain and for organizations needing to conduct audits. This document
can be used for audits of varying scope.
This document is adapted to fit the scope of an automotive cybersecurity engineering audit programme.
Cybersecurity audits in this document are aimed at cybersecurity activities at the organizational level.
While results from past projects can be used as evidence for implemented and applied processes, the
project and product levels are not in the focus of this document.
This document provides guidelines on the management of an audit programme, on the planning and
conducting of management system audits, as well as on the competence and evaluation of an audit team.
An audit can be conducted against a range of audit criteria. This document gives a set of audit criteria
based on ISO/SAE 21434 objectives. In addition, Annex A contains an example questionnaire that can be
adapted.
This document can be used for internal audits (first party), for audits conducted by organizations on
their external parties (second party) and for external audits conducted by third parties (e.g. for the
purpose of certification). This document can also be useful to organizations involved in auditor training
or personnel certification.

— competencies of CSMS auditors; and
— providing evidence during CSMS audits.
Elements of the CSMS are based on the processes described in ISO/SAE 21434. This document is
applicable to those needing to understand or conduct internal or external audits of a CSMS or to manage
a CSMS audit programme.
This document does not provide guidelines on cybersecurity assessments.

with “manage”, removed “cyber”, replaced “cyber attacks” with “threats”.]
3.3
risk
cybersecurity risk

4 Principles of auditing
The principles of auditing of ISO 19011:2018, Clause 4 apply. In addition, the following guidance applies.
The guidelines given in this document are aimed at what ISO/SAE 21434 defines as an organizational
cybersecurity audit. Product level topics are not in the scope of this document. Regarding products, a
cybersecurity assessment based on ISO/SAE 21434 is used to judge the cybersecurity of the item or
component.
5 Managing an audit programme
5.1 General
The guidelines of ISO 19011:2018, 5.1 apply.
5.2 Establishing audit programme objectives
The guidelines of ISO 19011:2018, 5.2 apply. In addition, the following guidance applies.
The audit programme objectives can be based on consideration of the following:
a) demonstration of the achievement of the objectives of ISO/SAE 21434;
b) specific cybersecurity risks associated with the auditee's products;
c) specifics related to the organization’s role in the automotive supply chain; and
2

ISO/PAS 5112:2022(E)
EXAMPLE 1 An organization’s role can be original equipment manufacturer (OEM), tier 1 supplier, tier 2
supplier, component manufacturer.
NOTE Organizations in the supply chain include organizations which develop components out of
context, e.g. before the placement of a purchase order, agreement, or other formal sourcing agreement.
d) clarification of whether the audit includes an evaluation of methods applied in the CSMS processes.
EXAMPLE 2 Specific audit programme objectives can include:
— verification of conformity of the CSMS with relevant legal and contractual requirements;
— obtaining and maintaining confidence in the auditee’s CSMS to identify, analyse and
evaluate the cybersecurity risk and to take corresponding necessary action; and
— evaluating the effectiveness of the CSMS to address cybersecurity risks.
5.3 Determining and evaluating audit programme risks and opportunities
The guidelines of ISO 19011:2018, 5.3 apply.
5.4 Establishing the audit programme
5.4.1 Roles and responsibilities of the individual(s) managing the audit programme
The guidelines of ISO 19011:2018, 5.4.1 apply.
5.4.2 Competence of individual(s) managing audit programme
The guidelines of ISO 19011:2018, 5.4.2 apply. In addition, the following guidance applies.
The individual(s) managing the CSMS audit programme should have the following competences:
a) knowledge of the standards regarding cybersecurity that are used by the auditee to establish and
maintain the CSMS;
b) knowledge of the general processes used by the automotive industry that are relevant for the
phase of the cybersecurity lifecycle which is evaluated within the specific scope of the audit (e.g.
processes for software development in the automotive domain);
c) ability to map the organization-specific processes, guidelines and rules with the audit criteria; and
d) if a combined audit is conducted, the ability to coordinate with other management system audit
programmes.
[8]
EXAMPLE A combined audit with IATF 16949 .
NOTE Considered competence can also include experience in audit or assessment of automotive processes
[8] [2] [5] [10]
based on automotive standards or guidelines, e.g. IATF 16949 , ISO 9001 , the ISO 26262 series , ASPICE .
5.4.3 Establishing extent of audit programme
The guidelines of ISO 19011:2018, 5.4.3 apply. In addition, the following guidance applies.
The extent of an audit programme can vary and can be impacted by the following factors:
a) size of the auditee and extent to which the auditee is involved in cybersecurity processes;
b) the cybersecurity-related supply chain and determination of which entities in the supply chain are
in scope; and

ISO/PAS 5112:2022(E)
c) importance of preserving cybersecurity property of information within the scope of the
cybersecurity processes.
5.4.4 Determining audit programme resources
The guidelines of ISO 19011:2018, 5.4.4 apply.
5.5 Implementing audit programme
5.5.1 General
The guidelines of ISO 19011:2018, 5.5.1 apply.
5.5.2 Defining the objectives, scope and criteria for an individual audit
The guidelines of ISO 19011:2018, 5.5.2 apply. In addition, the following guidance applies.
The audit scope should include the CSMS processes used by the auditee during the phases of the
cybersecurity lifecycle that are within the specific scope of the audit.
EXAMPLE 1 A tier 2 supplier might not be audited for all phases of the cybersecurity lifecycle.
The audit criteria should be defined following 6.4.8 and 6.4.9.
The audit scope may include the whole organization or one or more clearly delineated organizational
units.
NOTE 1 Clearly delineated organizational units are those that have separate organizational structures and
processes.
If the CSMS process depends on interactions with other organizational processes, the interfaces and
dependencies should be identified.
NOTE 2 Interfaces can include how work products are exchanged.
Shared functions outside the organization may be included in the scope of the audit with clearly defined
interfaces. If an organization depends on another organization to achieve the objectives of CSMS
processes, the contributing organization should be identified. The extent to which the organization
manages the dependencies on external organizations to realize its CSMS should be determined.
Distributed cybersecurity activities, defined in a cybersecurity interface agreement, may be included
in the scope of the audit.
EXAMPLE 2 Cybersecurity monitoring and cybersecurity incident response.
The audit objectives can include the confirmation of the suitability of the implemented processes and
applied methods and criteria to achieve the objectives of ISO/SAE 21434.
The auditee may perform an internal audit to identify and resolve shortcomings in the CSMS before an
external audit is conducted. If an external audit is planned as part of the audit programme, the scope
and objectives of both internal and external audits should be aligned.
A subsequent follow-up audit to address identified minor non-conformities of a conditionally-passed
audit may focus solely on the identified deficiencies noted.
5.5.3 Selecting and determining audit methods
The guidelines of ISO 19011:2018, 5.5.3 apply.
