PECB ISO-IEC-27001-Lead-Auditor Exam With Confidence Using Practice Dumps

Audit methods are the techniques and procedures that auditors use to collect and evaluate audit evidence. Audit methods can be classified into two categories: those that involve human interaction and those that do not. Human interaction methods are those that require direct or indirect communication with the auditee or other relevant parties, such as interviews, questionnaires, surveys, observations, or walkthroughs. Non-human interaction methods are those that do not require any communication with the auditee or other parties, such as document reviews, data analysis, or remote surveillance.

Some examples of audit methods that do not involve human interaction are:

Performing a review of auditee’s procedures in preparation for an audit: This method involves examining the auditee’s documented information, such as policies, processes, records, or reports, to verify their adequacy and effectiveness in meeting the audit criteria. The auditor does not need to interact with the auditee or anyone else to perform this method.

Analysing data by remotely accessing the auditee’s server: This method involves accessing and processing the auditee’s data, such as performance indicators, logs, metrics, or statistics, to verify their accuracy and reliability in meeting the audit criteria. The auditor does not need to interact with the auditee or anyone else to perform this method.

According to ISO 27001:2022 Annex A Control 8.30, the organisation shall ensure that externally provided processes, products or services that are relevant to the information security management system are controlled. This includes developing and entering into licensing agreements that cover code ownership and intellectual property rights, and implementing appropriate contractual requirements related to secure design and coding in accordance with Annex A 8.25 and 8.2912

In this case, the organisation and the developer have performed security tests that failed, which indicates that the secure design and coding requirements of Annex A 8.29 were not met. The IT Manager explains that the encryption and pseudonymization functions failed because they slowed down the system and service performance, and that an extra 150% of resources are needed to cover this. However, this does not justify the acceptance of the test results by the Service Manager, who is not authorised to approve the test according to the software security management procedure. The Service Manager should have consulted with the IT Manager, who is the owner of the process, and followed the procedure for handling nonconformities and corrective actions. The Service Manager’s decision to continue the service based on access control alone exposes the organisation to the risk of compromising the confidentiality, integrity, and availability of personal data processed by the mobile app. Therefore, there is a nonconformity (NC) with clause 8.1, control A.8.30.

According to ISO 27001:2022 Clause 8.1, the organisation shall plan, implement and control the processes needed to meet information security requirements, and to implement the actions determined in Clause 6.1. The organisation shall also control planned changes and review the consequences of unintended changes, taking action to mitigate any adverse effects, as necessary12

In this case, the organisation has not controlled the planned change of the mobile app from version 1.0 to version 1.01, which was a minor update provided by the outsourced developer in response to frequent ransomware attacks. The IT Manager explains that the developer performed an emergency release of the updated software, and gave a verbal guarantee that there will be no impact on any security functions. However, this is not sufficient to ensure that the change is properly assessed, tested, documented, and approved before deployment. The IT Manager should have followed the change management process and procedure, and verified that the updated software meets the security requirements and does not introduce any new vulnerabilities or risks. The IT Manager’s reliance on his 20 years of information security experience and the developer’s verbal guarantee is not a valid basis for skipping the re-testing of the software. Therefore, there is a nonconformity (NC) with clause 8.1.

From Exact Extract:

1. Identification of potential impact

The scenario clearly states that the chatbot:

Sent random files to users

Encountered invalid inputs

Processed personally identifiable information (PII)

Operated in a live customer-facing environment

Sending random files to users represents a direct risk of unauthorized disclosure of information, which could include:

Customer records

Sensitive operational data

Personally identifiable information (PII)

This constitutes a customer privacy breach, which is a serious information security impact.

2. ISO/IEC 27001:2022 – Impact on confidentiality

Under ISO/IEC 27001:2022, one of the core objectives of an ISMS is to protect confidentiality, especially where PII is involved.

Clause 6.1.2 (Information security risk assessment) requires organizations to identify risks related to loss of confidentiality.

Clause 6.1.3 (Information security risk treatment) requires controls to be implemented where such risks exist.

A system that distributes random files creates a high-impact confidentiality risk.

3. ISO/IEC 27002:2022 – Privacy and PII protection

This scenario directly impacts Annex A control A.5.34 – Privacy and protection of PII, which requires organizations to:

Protect personal data against unauthorized access, disclosure, or misuse.

The chatbot’s behaviour violates the intent of this control and demonstrates a clear privacy impact.

4. Why the other options are incorrect

A. Temporary slowdown in internal system updatesThis is not supported by the scenario. There is no reference to internal system updates being affected.

C. Minor delays in customer service response timesWhile customer support was overwhelmed, the scenario describes a much more severe impact — uncontrolled file transmission and potential data exposure. This understates the risk.

Auditor Conclusion

The most significant and realistic impact arising from the chatbot issues is a breach of customer privacy due to the potential exposure of sensitive files. This aligns with ISO/IEC 27001’s focus on protecting confidentiality and PII.
