ISO-IEC-27001-Lead-Auditor Exam Dumps : PECB Certified ISO/IEC 27001 2022 Lead Auditor exam

According to ISO 27001:2022 clause 9.1.2, the organisation shall conduct internal audits at planned intervals to provide information on whether the information security management system conforms to the organisation’s own requirements, the requirements of ISO 27001:2022, and is effectively implemented and maintained12

According to ISO 27001:2022 clause 10.1, the organisation shall react to the nonconformities and take action, as applicable, to control and correct them and deal with the consequences. The organisation shall also evaluate the need for action to eliminate the causes of nonconformities, in order to prevent recurrence or occurrence. The organisation shall implement any action needed, review the effectiveness of any corrective action taken, and make changes to the information security management system, if necessary12

A follow-up audit is a type of internal audit that is conducted after a previous audit to verify whether the nonconformities and corrective actions have been addressed and resolved, and whether the information security management system has been improved12

Therefore, the following statements are true for preparing a follow-up audit plan:

Verification should focus on whether any action undertaken is complete. This means that the auditor should check whether the organisation has implemented all the planned actions to correct and prevent the nonconformities, and whether the actions have been documented and communicated as required12

Verification should focus on whether any action undertaken has been undertaken effectively. This means that the auditor should check whether the organisation has achieved the intended results and objectives of the actions, and whether the actions have eliminated or reduced the nonconformities and their causes and consequences12

The following statements are false for preparing a follow-up audit plan:

Verification should focus on whether any action undertaken has been undertaken efficiently. This is false because efficiency is not a criterion for verifying the actions taken to address the nonconformities and corrective actions. Efficiency refers to the optimal use of resources to achieve the desired outcomes, but it is not a requirement of ISO 27001:2022. The auditor should focus on the effectiveness and completeness of the actions, not on the efficiency12

Corrections should be verified first, followed by corrective actions and finally opportunities for improvement. This is false because there is no prescribed order for verifying the corrections, corrective actions, and opportunities for improvement. The auditor should verify all the actions taken by the organisation, regardless of their sequence or priority. The auditor may choose to verify the actions based on their relevance, significance, or impact, but this is not a mandatory requirement12

Opportunities for improvement should be verified first, followed by corrections and finally corrective actions. This is false because there is no prescribed order for verifying the opportunities for improvement, corrections, and corrective actions. The auditor should verify all the actions taken by the organisation, regardless of their sequence or priority. The auditor may choose to verify the actions based on their relevance, significance, or impact, but this is not a mandatory requirement12

Corrective actions should be reviewed first, followed by corrections and finally opportunities for improvement. This is false because there is no prescribed order for reviewing the corrective actions, corrections, and opportunities for improvement. The auditor should review all the actions taken by the organisation, regardless of their sequence or priority. The auditor may choose to review the actions based on their relevance, significance, or impact, but this is not a mandatory requirement12

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.

Confidentiality is one of the principles of audit conduct that auditors should adhere to when performing audits. Confidentiality means that auditors should exercise discretion in the use and protection of information acquired in the course of their duties3. Auditors should respect the intellectual property rights of the auditee and other parties involved in the audit, and should not disclose any information that is sensitive, proprietary, or confidential without prior approval from the auditee or other authorized parties3. Auditors should also obtain the auditee’s permission before using a camera or recording equipment during an audit, as these devices may capture confidential information or infringe on the privacy of individuals3. Therefore, these two options correctly state the function of confidentiality in an audit. The other options are either incorrect or irrelevant to confidentiality. For example, auditors are not forced by regulatory requirements to maintain confidentiality in an audit, but rather by ethical obligations and contractual agreements3. Observers in an audit team can access confidential information if they have signed a confidentiality agreement and have been authorized by the auditee3. Audit information can be used for improving personal competence by the auditor only if it does not compromise confidentiality or conflict with other interests3. As an auditor is always accompanied by a guide, there is still a risk to the auditee’s sensitive information if the guide is not trustworthy or authorized to access such information3. References: ISO 19011:2018 - Guidelines for auditing management systems
