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

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.

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), clause 5.2 requires top management to establish an information security policy that provides the framework for setting information security objectives1. Clause 6.2 requires top management to ensure that the information security objectives are established at relevant functions and levels1. Therefore, when verifying that the information security policy and objectives have been established by top management, an ISMS auditor should review relevant documents and records that demonstrate top management’s involvement and commitment.

To verify that the mobile device policy and objectives are implemented and effective, an ISMS auditor should review relevant documents and records that demonstrate how the policy and objectives are communicated, monitored, measured, analyzed, and evaluated. The auditor should also sample and verify the implementation of the controls that are stated in the policy.

Three options for the audit trail that are relevant to verifying the mobile device policy and objectives are:

Review the internal audit report to make sure the IT department has been audited: This option is relevant because it can provide evidence of how the IT department, which is responsible for managing the mobile devices and their security, has been evaluated for its conformity and effectiveness in implementing the mobile device policy and objectives. The internal audit report can also reveal any nonconformities, corrective actions, or opportunities for improvement related to the mobile device policy and objectives.

Sampling some mobile devices from on-duty medical staff and validate the mobile device information with the asset register: This option is relevant because it can provide evidence of how the mobile devices that are used by the medical staff, who are involved in processing and storing residents’ data, are registered in the asset register and have physical protection enabled. This can verify the implementation and effectiveness of two of the controls that are stated in the mobile device policy.

Review the asset register to make sure all company’s mobile devices are registered: This option is relevant because it can provide evidence of how the company’s mobile devices that are within the ISMS scope are identified and accounted for. This can verify the implementation and effectiveness of one of the controls that are stated in the mobile device policy.

The other options for the audit trail are not relevant to verifying the mobile device policy and objectives, as they are not related to the policy or objectives or their implementation or effectiveness. For example:

Interview the reception personnel to make sure all visitor and employee bags are checked before entering the nursing home: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding physical security or access control, but not specifically to mobile devices.

Review visitors’ register book to make sure no visitor can have their personal mobile phone in the nursing home: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding information security awareness or compliance, but not specifically to mobile devices.

Interview the supplier of the devices to make sure they are aware of the ISMS policy: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding information security within supplier relationships, but not specifically to mobile devices.

Interview top management to verify their involvement in establishing the information security policy and the information security objectives: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to verifying that the information security policy and objectives have been established by top management, but not specifically to mobile devices.
