INTRODUCTION
,The ISO 28000 Supply Chain Security Management Systems Lead
Auditor examination assesses the knowledge, skills, and judgment
required to plan, conduct, and lead conformity assessment audits of
security management systems. The examination evaluates
foundational security management theory, ISO 28000:2022
requirement interpretation, audit principles per ISO 19011:2018, risk-
based auditing techniques, and real-world decision-making through
multiple-choice and scenario-based questions. Candidates must
demonstrate competency in applying audit evidence collection
methods, evaluating conformity, managing audit teams, and
upholding professional ethics throughout the audit lifecycle.
SECTION ONE: QUESTIONS 1–100
Question 1

certification audit of a logistics company. Which of the following
should be the primary consideration when determining audit
priorities?
A. The auditee's preferred schedule for operational convenience
B. The risks associated with the organization's supply chain security
processes and the significance of their potential failure
C. The number of employees in each department to ensure equal
audit time allocation
D. The alphabetical order of the organization's documented
procedures
, B. The risks associated with the organization's supply chain
security processes and the significance of their potential failure
RATIONALE: Risk-based audit planning is a core principle
under ISO 19011:2018. The audit programme and individual audit
plans should prioritize processes and areas with higher security
risks and greater significance to the supply chain security
management system, ensuring that audit resources are directed
where they are most needed.
Question 2
What is the primary objective of ISO 28000:2022?
A. To improve product quality and customer satisfaction in
manufacturing supply chains
B. To specify requirements for a security management system,
including aspects critical to security assurance of the supply chain
C. To provide guidelines for environmental management in logistics
operations
D. To establish financial auditing standards for international trade
B. To specify requirements for a security management system,
including aspects critical to security assurance of the supply chain
RATIONALE: ISO 28000:2022 is titled "Security and resilience
— Security management systems — Requirements" and specifies
requirements for a security management system, including those
aspects critical to security assurance of the supply chain. Its focus is
, on managing security risks and ensuring resilience, not product
quality or environmental management.
Question 3
During an ISO 28000 audit, the lead auditor discovers that the
organization's security risk assessment has not been updated
despite significant geopolitical changes affecting its supply routes.
Which audit principle is most relevant to evaluating this situation?
A. Independence and impartiality
B. Confidentiality
C. Due professional care
D. Evidence-based approach
C. Due professional care
RATIONALE: Due professional care requires auditors to apply
diligence and sound judgment in evaluating the auditee's
conformity. A risk assessment that fails to reflect changed threat
conditions indicates a potential nonconformity with ISO 28000's
requirement for ongoing risk assessment and planning. The auditor
must exercise professional judgment in determining the severity
and implications of this finding.
Question 4
Which clause of ISO 28000:2022 specifies requirements for
understanding the organization and its context?
