Yes, assessing the ISMS as a whole can be acceptable if the audit team obtains reasonable assurance that the system conforms to the standard requirements. The approach taken by the audit team must still ensure that all significant aspects of the ISMS are evaluated adequately, and if this is achieved through a holistic assessment, it is considered sufficient.

This scenario represents ordinary negligence, making option A the correct answer. Ordinary negligence occurs when an individual fails to exercise the level of care, competence, or diligence that would reasonably be expected under similar circumstances. In the context of ISO/IEC 27001 certification audits, this includes failing to follow established audit procedures, best practices, or competence requirements, even if there is no intent to cause harm.
In the scenario, the audit team leader failed to follow established best practices and lacked sufficient expertise in certain complex ISMS areas. These shortcomings resulted in weak audit coverage and suboptimal outcomes. However, the audit was still conducted, findings were reported, and there is no indication of reckless disregard, willful misconduct, or intentional violation of duties. This distinction is important when assessing the severity of negligence.
Gross negligence would require evidence of a serious departure from accepted standards, such as knowingly ignoring mandatory audit requirements, deliberately conducting an audit without any competence, or showing reckless indifference to the consequences. That threshold is not met here. Similarly, option C is incorrect because the presence of procedural failures and competence gaps clearly indicates some level of negligence.
ISO 19011:2018 emphasizes auditor competence, due professional care, and adherence to audit principles.
Failure to meet these expectations constitutes negligence, but in this case, it remains within the bounds of ordinary negligence rather than gross negligence.

From Exact Extract:
1. Definition of control types (ISO-aligned understanding)
In information security management:
* Preventive controls are designed to prevent an incident from occurring.
* Detective controls are designed to identify and detect incidents or anomalies after or as they occur.
* Corrective controls are designed to correct issues after detection.
2. Analysis of the controls implemented by Fintive
The scenario explicitly states that Fintive implemented the following controls:
* Comprehensive audit logging
* Automated alert systems to flag unusual activities
* Periodic access reviews
* Monitoring system behavior for anomalies
All of these controls are designed to:
* Detect unauthorized access
* Detect errors
* Detect suspicious activities
* Enable investigation after detection
This aligns directly with detective controls, not preventive or corrective.
3. ISO/IEC 27002:2022 - Exact control alignment
The controls implemented correspond to Annex A technological and organisational detective controls, including:
* A.8.15 - Logging
Logging enables the detection and investigation of security events.
* A.8.16 - Monitoring activities
Monitoring is used to detect anomalous behaviour and potential security incidents.
* A.5.18 - Access rights (periodic reviews)
Access reviews detect inappropriate or excessive access.
These controls do not prevent the chatbot from malfunctioning, nor do they directly fix it - they detect issues so that action can be taken.
4. Why the other options are incorrect
* A. Preventive - IncorrectPreventive controls would include secure coding practices, input validation, sandboxing, or improved testing before release. These were not the controls described.
* C. Corrective - IncorrectCorrective controls would involve fixing the chatbot logic, retraining the model, or disabling unsafe features. The scenario explicitly focuses on detection and monitoring, not correction.
Auditor Conclusion
Fintive implemented detective controls to identify unauthorized access, errors, and suspicious activity arising from the chatbot's behaviour. This is consistent with ISO/IEC 27001:2022 risk treatment and monitoring requirements.

The three Annex A controls that you would expect the auditee to have implemented when you conduct the follow-up audit are:
* B. 5.13 Labelling of information
* E. 5.34 Privacy and protection of personal identifiable information (PII)
* G. 6.3 Information security awareness, education, and training
* B. This control requires the organisation to label information assets in accordance with the information classification scheme, and to handle them accordingly12. This control is relevant for the auditee because it could help them to avoid misaddressing labels and sending parcels to wrong destinations, which could compromise the confidentiality, integrity, and availability of the information assets. By labelling the information assets correctly, the auditee could also ensure that they are delivered to the intended recipients and that they are protected from unauthorized access, use, or disclosure.
* E. This control requires the organisation to protect the privacy and the rights of individuals whose personal identifiable information (PII) is processed by the organisation, and to comply with the applicable legal and contractual obligations13. This control is relevant for the auditee because it could help them to prevent the unauthorized use of residents' personal data by a supplier, which could violate the privacy and the rights of the residents and their family members, and expose the auditee to legal and reputational risks. By protecting the PII of the residents and their family members, the auditee could also enhance their trust and satisfaction, and avoid complaints and disputes.
* G. This control requires the organisation to ensure that all employees and contractors are aware of the information security policy, their roles and responsibilities, and the relevant information security procedures and controls14. This control is relevant for the auditee because it could help them to improve the information security culture and behaviour of their staff, and to reduce the human errors and negligence that could lead to information security incidents. By providing information security awareness, education, and training to their staff, the auditee could also increase their competence and performance, and ensure the effectiveness and efficiency of the information security processes and controls.

According to ISO/IEC 17021-1, which specifies the requirements for bodies providing audit and certification of management systems, a certification body should ensure that its auditors are competent, impartial, and independent from the auditee organization2. Therefore, if a Management System Representative of a client organization asks for a specific auditor for the certification audit, the individual(s) managing the audit programme should respond in a way that does not compromise these principles or create any conflict of interest or undue influence2. Two possible ways to respond are to state that his request will be considered but may not be taken up, as there may be other factors that affect the auditor selection process; or to advise him that the audit team selection is a decision that the audit programme manager needs to make based on the resources available, such as auditor availability, competence, location, etc2. The other options are not suitable ways to respond in this situation. For example, advising him that his request can be accepted may raise doubts about the objectivity and credibility of the auditor and the certification body; suggesting that he chooses another certification body may imply that his request is unreasonable or unethical; and suggesting asking the certification body management to permit his request may suggest that there is room for negotiation or manipulation in auditor selection2.
