Materiality should be considered during the initial contact to obtain reasonable assurance that the audit can be successfully completed. Determining materiality helps establish the threshold for the significance of audit findings, ensuring that the audit focuses on substantial issues that could impact the audit conclusions.

The correct response is A, because grading criteria provide a common basis for the evaluation of nonconformities across the organization. Grading criteria are the rules or standards that define the severity or impact of nonconformities, and help to determine the appropriate corrective actions and follow-up activities. Grading criteria are important for several reasons, such as:

They ensure consistency and objectivity in the assessment and reporting of nonconformities, and avoid subjective or arbitrary judgments.

They facilitate the communication and understanding of nonconformities among the auditors, the auditees, and the audit clients, and enable the comparison and benchmarking of nonconformities across different processes, functions, or locations.

They support the prioritization and allocation of resources for the resolution of nonconformities, and the monitoring and measurement of the effectiveness of the corrective actions.

They demonstrate the commitment and accountability of the organization to the continual improvement of the ISMS, and the compliance with the ISMS requirements and expectations.

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.5.29 requires an organization to establish and maintain a business continuity management process to ensure the continued availability of information and information systems at the required level following disruptive incidents1. The organization should identify and prioritize critical information assets and processes, assess the risks and impacts of disruptive incidents, develop and implement business continuity plans (BCPs), test and review the BCPs, and ensure that relevant parties are aware of their roles and responsibilities1. Therefore, when verifying the information security of the business continuity management process, an ISMS auditor should verify that these aspects are met in accordance with the audit criteria.

Three options that will be in the audit trail for verifying control A.5.29 are:

Collect more evidence on how the organisation manages information security on mobile devices and during teleworking (Relevant to control A.6.7): This option is relevant because it can provide evidence of how the organization has implemented appropriate controls to protect the confidentiality, integrity and availability of information and information systems when staff work from home using mobile devices, such as laptops, tablets or smartphones. This is related to control A.6.7, which requires an organization to establish a policy and procedures for teleworking and use of mobile devices1.

Collect more evidence on how and when the Business Continuity Plan has been tested (Relevant to control A.5.29): This option is relevant because it can provide evidence of how the organization has tested and reviewed the BCPs to ensure their effectiveness and suitability for different scenarios, such as a pandemic. This is related to control A.5.29, which requires an organization to test and review the BCPs at planned intervals or when significant changes occur1.

Collect more evidence on how the organisation makes sure only staff with a negative test result can enter the organisation (Relevant to control A.7.2): This option is relevant because it can provide evidence of how the organization has implemented appropriate controls to prevent or reduce the risk of infection or transmission of diseases among staff or residents, such as requiring regular staff self-testing and using a health status app. This is related to control A.7.2, which requires an organization to ensure that all employees and contractors are aware of information security threats and concerns, their responsibilities and liabilities, and are equipped to support organizational policies and procedures in this respect1.

The other options are not relevant to verifying control A.5.29, as they are not related to the control or its requirements. For example:

Collect more evidence by interviewing more staff about their feeling about working from home (Relevant to clause 4.2): This option is not relevant because it does not provide evidence of how the organization has established and maintained a business continuity management process or ensured the continued availability of information and information systems following disruptive incidents. It may be related to clause 4.2, which requires an organization to understand the needs and expectations of interested parties, but not specifically to control A.5.29.

Collect more evidence on what resources the organisation provides to support the staff working from home (Relevant to clause 7.1): This option is not relevant because it does not provide evidence of how the organization has established and maintained a business continuity management process or ensured the continued availability of information and information systems following disruptive incidents. It may be related to clause 7.1, which requires an organization to determine and provide the resources needed for its ISMS, but not specifically to control A.5.29.

Collect more evidence on how the organisation performs a business risk assessment to evaluate how fast the existing residents can be discharged from the nursing home (Relevant to clause 6): This option is not relevant because it does not provide evidence of how the organization has established and maintained a business continuity management process or ensured the continued availability of information and information systems following disruptive incidents. It may be related to clause 6, which requires an organization to plan actions to address risks and opportunities for its ISMS, but not specifically to control A.5.29.

Comprehensive and Detailed In-Depth Explanation:Northstorm adopted an international standard for Personally Identifiable Information (PII) controllers and PII processors to ensure its data handling practices were secure and compliant with global regulations. This aligns directly with ISO/IEC 27701, which extends ISO/IEC 27001 and ISO/IEC 27002 to cover Privacy Information Management Systems (PIMS), specifically addressing the protection of PII.

A. ISO/IEC 27701 – Correct Answer. This standard is designed for organizations acting as PII controllers and processors and provides guidelines on privacy management, regulatory compliance, and data protection.

B. ISO/IEC 27009 – Incorrect because this standard provides guidance on sector-specific requirements for ISMS, not privacy or PII protection.

C. ISO/IEC 27003 – Incorrect because it provides general implementation guidance for ISMS, not specific controls for PII processing.

This aligns with ISO/IEC 27001:2022 Annex A Control A.5.34 (Privacy and Protection of PII), which focuses on ensuring compliance with privacy regulations and implementing privacy-enhancing security measures.

Jack collected mathematical evidence when he identified nonconformities by comparing the number of purchased invoices for software licenses with the software inventory. This type of evidence involves numerical, quantifiable data that highlights discrepancies and supports findings of compliance or non-compliance.

The role of the audit team leader does not include setting up an ethics committee. The primary responsibilities of the audit team leader include planning the audit, directing the activities of the audit team, ensuring compliance with the auditing standards, managing conflicts that arise during the audit, and presenting audit conclusions.

Comprehensive and Detailed In-Depth Explanation:A vulnerability in information security refers to a weakness in a system, process, or software that can be exploited, leading to security incidents. In this case, the most significant vulnerability in Northstorm’s system was the installation of an illegitimate (compromised) version of the application, which directly impacted the main server and resulted in system downtime.

A. The new version of the application directly affecting the main server is an outcome rather than the vulnerability itself. The reason it affected the server was due to its compromised nature.

B. The need for a replacement version of the application is not a vulnerability but rather a necessity due to the incompatibility issue introduced by the OS upgrade.

C. The new version of the application being illegitimate is the true vulnerability because it represents an unauthorized or unverified change that introduced malicious code or other security risks. This could have been mitigated by proper validation, secure software development practices, and adherence to change management policies outlined in ISO/IEC 27001:2022 Annex A controls:

A.8.8 Management of Technical Vulnerabilities – Ensures that systems and applications are updated and maintained securely.

A.8.9 Configuration Management – Covers proper software deployment and validation procedures.

A.8.14 Redundancy of Information Processing Facilities – Ensures resilience to failures like server downtimes.

This incident underscores the importance of implementing rigorous change management processes and software validation measures to prevent the installation of unauthorized software, a key requirement under ISO/IEC 27001:2022 Clause 8 (Operational Planning and Control).

The four options for the actions you could take are A, C, F, and G. These options are consistent with the guidance and requirements of ISO 19011:2018, Clause 6.712. You could agree with the auditee/audit client how the remaining nonconformity will be cleared, by when, and how its clearance will be verified (A), and document the agreement in the audit report1. You could close the follow-up audit as the organisation has demonstrated it is committed to clearing the nonconformities raised ©, and report the outcome to the audit client and other relevant parties1. You could note the progress made but hold the audit open until all corrective action has been cleared (F), and determine the need for another follow-up audit or other actions1. You could also advise the individual managing the audit programme of any decision taken regarding the outstanding nonconformity (G), as they are responsible for the overall management and coordination of the audit programme3. The other options are either not appropriate or not necessary for the situation. You should not recommend that the outstanding minor nonconformity is dealt with at the next surveillance audit (B), as this may compromise the audit objectives and the audit programme1. You should not recommend suspension of the organisation’s certification as they have failed to implement the agreed corrections and corrective actions within the agreed timescale (D), as this is not within your role or authority as an ISMS auditor4. You should not advise the auditee that you will arrange for the next audit to be an online audit to deal with the outstanding nonconformity (E), as this may not be feasible or effective depending on the nature and complexity of the nonconformity1. You should not conduct an unannounced follow-up audit on-site to review the one outstanding minor nonconformity once it has been cleared (H), as this may not be in accordance with the audit agreement or the audit programme1.

According to the PECB Candidate Handbook1, one of the principles of auditing is confidentiality, which means that auditors should respect the confidentiality of information obtained during the audit and not disclose it to unauthorized parties. The handbook also states that auditors should only report audit results to those who have a legitimate need to know, such as the client, the auditee, and the certification body. Therefore, sharing the findings with other relevant managers in A or B’s other customers would be a breach of confidentiality, as they are not directly involved in the audit process or the information security management system of B. Sharing the findings with B’s Information Security Manager or other relevant managers in B would be appropriate, as they are part of the auditee organization and responsible for the implementation and improvement of the ISMS. Sharing the findings with A’s supplier evaluation team or B’s certification body would also be acceptable, as they have a legitimate need to know the audit results for the purpose of supplier selection or certification, respectively. References: 1: PECB Candidate Handbook - ISO 27001 Lead Auditor, pages 7-8.
