ISO 19011:2018 (Audit Guidelines) allows process simulations to verify control effectiveness. Webvue's personnel conducted the test under audit supervision, ensuring realistic evaluation without operational disruption. A: Incorrect: Simulations are valid audit techniques and do not negatively impact operations if performed properly. B: Incorrect: Technical experts assist auditors, but the focus is on ensuring accurate control verification, not the auditor's competence. Relevant Standard Reference: ISO 19011:2018 Clause 6.4.8 (Process Simulation for Audit Evidence Collection) Explanation: Comprehensive and Detailed In-Depth
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: competence of the audit team and decision made by the certification body According to ISO/IEC 17021-1, which specifies the requirements for bodies providing audit and certification of management systems, an accredited certification means that the certification body has been evaluated by an accreditation body against recognized standards to demonstrate its competence, impartiality and performance capability1. Therefore, an accredited certification assures the competence of the audit team that conducts the audit in accordance with ISO 19011 and ISO/IEC 27001:2022, and the decision made by the certification body that grants or maintains the certification based on the audit evidence and findings2. References: ISO/IEC 17021-1:2015 - Conformity assessment - Requirements for bodies providing audit and certification of management systems - Part 1: Requirements, ISO/IEC 27001:2022 Lead Auditor (Information Security Management Systems) | CQI | IRCA
According to ISO 19011:2018, which provides guidelines for auditing management systems, clause 6.6 requires the audit team leader to conduct a closing meeting with the auditee's representatives at the end of the audit to present the audit conclusions and any findings1. The closing meeting should also provide an opportunity for the auditee to ask questions, clarify issues, acknowledge the findings, and comment on the audit process1. Therefore, when preparing for the closing meeting, an ISMS auditor should consider the following actions: I will advise the auditee that the purpose of the closing meeting is for the audit team to communicate our findings. It is not an opportunity for the auditee to challenge these: This action is appropriate because it reflects the fact that the auditor has followed a systematic and consistent approach to collecting and evaluating audit evidence and reaching audit conclusions. The auditor should advise the auditee that the purpose of the closing meeting is for the audit team to communicate their findings, which are based on objective evidence and professional judgement. The auditor should also explain that it is not an opportunity for the auditee to challenge these findings, as they have already been discussed and confirmed during the audit. However, the auditor should also invite the auditee to ask questions, clarify issues, acknowledge the findings, and comment on the audit process1. I will schedule a closing meeting with the auditee's representatives at which the audit conclusions will be presented: This action is appropriate because it reflects the fact that the auditor has followed a planned and agreed audit programme and schedule. The auditor should schedule a closing meeting with the auditee's representatives at which the audit conclusions will be presented, in accordance with clause 6.6 of ISO 19011:20181. The auditor should also ensure that the closing meeting is attended by those responsible for managing or implementing the ISMS, as well as any other relevant parties1. I will discuss any follow-up required with my audit team: This action is appropriate because it reflects the fact that the auditor has followed a risk-based approach to determining and reporting any follow-up actions required by the auditee or the certification body. The auditor should discuss any follow-up required with their audit team, such as verifying corrective actions for nonconformities or conducting a subsequent audit1. The auditor should also document any follow-up actions in the audit report1. I will review and, as appropriate, approve my teams audit conclusions: This action is appropriate because it reflects the fact that the auditor has followed a rigorous and professional process to reaching and reporting audit conclusions. The auditor should review and, as appropriate, approve their teams audit conclusions, which are based on objective evidence and professional judgement. The auditor should also ensure that their teams audit conclusions are consistent with the audit objectives and scope, and reflect the overall performance and conformity of the ISMS1.
The best action to take in this scenario is to determine whether any additional effective arrangements are in place to verify individual access to secure areas, such as CCTV. This action is consistent with the audit principle of evidence-based approach, which requires the auditor to obtain sufficient and appropriate audit evidence to support the audit findings and conclusions1. By verifying the existence and effectiveness of other security controls, the auditor can assess the extent and impact of the nonconformity observed, and determine the appropriate audit finding and recommendation. The other options are not the best actions to take in this scenario, because they are either premature or inappropriate. For example: * Option A is inappropriate, because it is not the auditor's role to suggest specific solutions or improvements to the auditee, but rather to report the audit findings and recommendations based on the audit criteria and objectives2. A large sign in reception may not be an effective or feasible solution to address the issue of tailgating, and it may not reflect the root cause of the problem. * Option C is premature, because it assumes that the control A.7.1 'security perimeters' is not adequately implemented, without verifying the existence and effectiveness of other security controls that may compensate for the observed nonconformity. The auditor should not jump to conclusions based on a single observation, but rather gather sufficient and appropriate audit evidence to support the audit finding3. * Option D is premature, because it assumes that the control A.7.6 'working in secure areas' is not adequately implemented, without verifying the existence and effectiveness of other security controls that may compensate for the observed nonconformity. The auditor should not jump to conclusions based on a single observation, but rather gather sufficient and appropriate audit evidence to support the audit finding3. * Option E is inappropriate, because it is not related to the observed nonconformity, which is about the access control to secure areas, not the information security requirements agreed upon with the supplier. The auditor should not raise a nonconformity based on irrelevant or incorrect audit criteria4. * Option F is inappropriate, because it is not the auditor's role to suggest specific solutions or improvements to the auditee, but rather to report the audit findings and recommendations based on the audit criteria and objectives2. Requiring contractors to be accompanied at all times when accessing secure facilities may not be an effective or feasible solution to address the issue of tailgating, and it may not reflect the root cause of the problem.
