Explanation
According to the ISO/IEC 27001:2022 Lead Auditor (Information Security Management Systems) course, the following actions should be taken when a nonconformity identified for completion before the follow-up audit is still outstanding:
* A. Report the failure to address the corrective action for the outstanding nonconformity to the organisation's top management. This is part of the auditor's responsibility to communicate the audit results and ensure that the audit objectives are met12.
* C. If the delay is justified agree on a revised date for clearing the nonconformity with the auditee/audit client. This is part of the auditor's responsibility to verify the effectiveness of the corrective actions taken by the auditee and to close the nonconformity when the evidence is satisfactory12.
* E. Decide whether the delay in addressing the nonconformity is justified. This is part of the auditor's responsibility to evaluate the evidence presented by the auditee and to use professional judgement and objectivity to determine the validity of the reasons for the delay12.
* G. Note the nonconformity is still outstanding and follow audit trails to determine why. This is part of the auditor's responsibility to collect and verify audit evidence and to identify the root causes of the nonconformity12.

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), control A.7.2 requires an organization to implement appropriate physical entry controls to prevent unauthorized access to secure areas1. The organization should define and document the criteria for granting and revoking access rights to secure areas, and should monitor and record the use of such access rights1. Therefore, when auditing the organization's application of control A.7.2, an ISMS auditor should verify that these aspects are met in accordance with the audit criteria.
Based on the scenario above, the auditor should raise a nonconformity against control A.7.2, as the secure area is not adequately protected from unauthorized access. The auditor should provide the following evidence and justification for the nonconformity:
* Evidence: The auditor observed two external contractors using a swipe card and combination number provided by the centre's reception desk to gain access to a client's suite to carry out authorized electrical repairs. The auditor checked the door access record for the client's suite and found that only one card was swiped. The auditor asked the receptionist and was told that it was a common problem that contractors tend to swipe one card and tailgate their way in, but they were known from the reception sign-in.
* Justification: This evidence indicates that the organization has not implemented appropriate physical entry controls to prevent unauthorized access to secure areas, as required by control A.7.2. The organization has not defined and documented the criteria for granting and revoking access rights to secure areas, as there is no verification or authorization process for providing swipe cards and combination numbers to external contractors. The organization has not monitored and recorded the use of access rights to secure areas, as there is no mechanism to ensure that each individual swipes their card and enters their combination number before entering a secure area. The organization has relied on the reception sign-in as a means of identification, which is not sufficient or reliable for ensuring information security.
The other options are not valid actions for auditing control A.7.2, as they are not related to the control or its requirements, or they are not appropriate or effective for addressing the nonconformity. For example:
* Take no action: This option is not valid because it implies that the auditor ignores or accepts the nonconformity, which is contrary to the audit principles and objectives of ISO 19011:20182, which provides guidelines for auditing management systems.
* Raise a nonconformity against control A.5.20 'addressing information security in supplier relationships' as information security requirements have not been agreed upon with the supplier: This option is not valid because it does not address the root cause of the nonconformity, which is related to physical entry controls, not supplier relationships. Control A.5.20 requires an organization to agree on information security requirements with suppliers that may access, process, store, communicate or provide IT infrastructure components for its information assets1. While this control may be relevant for ensuring information security in supplier relationships, it does not address the issue of unauthorized access to secure areas by external contractors.
* Raise a nonconformity against control A.7.6 'working in secure areas' as security measures for working in secure areas have not been defined: This option is not valid because it does not address the root cause of the nonconformity, which is related to physical entry controls, not working in secure areas. Control A.7.6 requires an organization to define and apply security measures for working in secure areas1.
While this control may be relevant for ensuring information security when working in secure areas, it does not address the issue of unauthorized access to secure areas by external contractors.
* Determine whether any additional effective arrangements are in place to verify individual access to secure areas e.g. CCTV: This option is not valid because it does not address or resolve the nonconformity, but rather attempts to find alternative or compensating controls that may mitigate its impact or likelihood. While additional arrangements such as CCTV may be useful for verifying individual access to secure areas, they do not replace or substitute the requirement for appropriate physical entry controls as specified by control A.7.2.
* Raise an opportunity for improvement that contractors must be accompanied at all times when accessing secure facilities: This option is not valid because it does not address or resolve the nonconformity, but rather suggests a possible improvement action that may prevent or reduce its recurrence or severity.
* While accompanying contractors at all times when accessing secure facilities may be a good practice for ensuring information security, it does not replace or substitute the requirement for appropriate physical entry controls as specified by control A.7.2.
* Raise an opportunity for improvement to have a large sign in reception reminding everyone requiring access must use their swipe card at all times: This option is not valid because it does not address or resolve the nonconformity, but rather suggests a possible improvement action that may increase awareness or compliance with the existing controls. While having a large sign in reception reminding everyone requiring access must use their swipe card at all times may be a helpful reminder for ensuring information security, it does not replace or substitute the requirement for appropriate physical entry controls as specified by control A.7.2.
* Tell the organisation they must write to their contractors, reminding them of the need to use access cards appropriately: This option is not valid because it does not address or resolve the nonconformity, but rather instructs the organization to take a corrective action that may not be effective or sufficient for ensuring information security. While writing to contractors, reminding them of the need to use access cards appropriately may be a communication measure for ensuring information security, it does not replace or substitute the requirement for appropriate physical entry controls as specified by control A.7.2.

Explanation
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.

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.
