PECB ISO-IEC-27001-Lead-Auditor Exam - Topic 3 Question 74 Discussion

Posted by Marguerita on Aug 16, 2026 at 03:11 PM

Scenario 3

NightCore, a multinational technology enterprise headquartered in the United States, specializes in e-commerce, cloud computing, digital streaming, and artificial intelligence (AI). After having an information security management system (ISMS) implemented for over a year, NightCore contracted a certification body to perform an audit for ISO/IEC 27001 certification.

The certification body formed a team of five auditors, with Jack as a team leader. Jack is renowned for his extensive auditing experience in risk management, information security controls, and incident management. His skill set aligns well with the requirements of auditing principles and processes, enabling him to effectively comprehend the audit scope and apply relevant criteria effectively. Jack also demonstrates a solid understanding of NightCore's organizational structure, purpose, and management practices and the statutory and regulatory requirements applicable to its activities.

The audit carried out by the audit team followed a rational method to reach reliable and reproducible conclusions systematically. The audit team recognized that only information capable of being verified to some extent should be considered valid evidence. In some rare instances during the audit where the verification of certain information posed challenges and where its degree of verifiability was low, the auditors exercised their professional judgment to assess the reliability and determine the level of reliance that could be placed on such evidence.

During the audit, the auditors documented their observations and inspection notes regarding the operational planning and control of NightCore's ISMS operations. They also recorded observations of NightCore's inventory of information and associated assets. Additionally, the auditors reviewed the configuration of firewalls implemented to secure connections to network services.

As the audit approached its final stages, NightCore's commitment to upholding the highest levels of information security became evident. With ISO/IEC 27001 certification within reach, NightCore is well-positioned to achieve ISO/IEC 27001 certification, enhancing its reputation in the technology sector.

What type of audit did NightCore undergo?

Suggested Answer: C

NightCore underwent a third-party audit, making option C the correct answer. A third-party audit is conducted by an independent certification body for the purpose of assessing conformity against a recognized international standard, such as ISO/IEC 27001. This type of audit is required when an organization seeks formal certification.

In the scenario, NightCore explicitly contracted a certification body to perform an audit for ISO/IEC 27001 certification. The audit team was formed by the certification body, not by NightCore itself or by a customer or supplier. This independence is the defining characteristic of a third-party audit. The objective of such an audit is to determine whether the ISMS conforms to ISO/IEC 27001 requirements and whether certification can be granted.

Option A is incorrect because a first-party audit is an internal audit conducted by or on behalf of the organization itself. Although NightCore had conducted internal audits previously, the scenario clearly refers to a certification audit performed by an external body. Option B is incorrect because a second-party audit is conducted by an interested party, such as a customer auditing a supplier, which is not the case here.

Therefore, based on the involvement of an independent certification body and the goal of ISO/IEC 27001 certification, the audit conducted at NightCore is correctly classified as a third-party audit.

I recall similar questions where the distinction between first, second, and third-party audits was crucial. This definitely sounds like a third-party audit to me.

Based on what I studied, a second-party audit is usually between a supplier and a customer. This doesn't fit, so it must be third-party.

I'm not entirely sure, but I remember something about first-party audits being internal. This seems more like an external evaluation.

I think NightCore underwent a third-party audit since they hired an external certification body for ISO/IEC 27001.
