Relevant Standard Reference:

ISO 19011:2018 Clause 6.4.7 (Audit Program Limitations)

The conclusion in the audit report that is not required by the certification body when deciding to grant certification is that the organisation fully complies with all legal and other requirements applicable to the ISMS. This is because the certification body does not have the authority or the responsibility to verify the legal compliance of the organisation, as this is outside the scope of ISO/IEC 27001:2022. The certification body only evaluates the conformity of the organisation’s ISMS with the requirements of the standard, which include the establishment of a process to identify and evaluate the legal and other requirements that are relevant to the ISMS. The organisation is responsible for ensuring its own legal compliance and for providing evidence of such compliance to the certification body if requested.

The correct responsibility with each participant of a second-party audit is:

Prepares the audit report: Audit Team Leader. The audit team leader is responsible for coordinating the audit activities, communicating with the auditee and the customer, and preparing and delivering the audit report that summarizes the audit findings and conclusions1.

Prepares audit checklists for use during the audit: Auditor. The auditor is responsible for collecting and verifying objective evidence during the audit, using audit checklists as a tool to guide the audit process and ensure that all relevant aspects of the audit criteria are covered1.

Supports an auditor and provides feedback on their experience: Auditor in training. The auditor in training is a person who is learning how to perform audits under the supervision of an experienced auditor. The auditor in training supports the auditor by observing and participating in the audit activities, and provides feedback on their experience to improve their skills and competence1.

Follows-up on audit findings within an agreed timeframe: Auditee. The auditee is the organisation that is being audited by the customer or a third party on behalf of the customer. The auditee is responsible for providing access and cooperation to the auditors, and for following up on the audit findings within an agreed timeframe, by implementing corrective actions or improvement measures as needed1.

Provides an independent account of the audit but does not participate in the audit: Observer. The observer is a person who accompanies the audit team but does not participate in the audit activities. The observer may be a representative of the customer, a regulatory body, or another interested party. The observer provides an independent account of the audit but does not interfere with or influence the audit process or outcome1.

Escorts the auditors but does not participate in the audit: Guide. The guide is a person who is appointed by the auditee to assist the audit team during the audit. The guide may escort the auditors to different locations, facilitate access to information and personnel, or provide clarification or explanation as requested by the auditors. The guide does not participate in the audit or influence its results1.

Qualitative evidence in an audit typically involves observations, interviews, and reviews that provide insights into the processes and compliance through subjective but informed assessments. An interview with information security personnel to validate compliance with the standard requirements is an example of qualitative evidence, where the quality and effectiveness of processes are assessed based on expert judgments rather than measurable metrics.

The three options of the corrections and corrective actions listed that you would expect ABC to make in response to the nonconformity are:

B. ABC cancels the service agreement with WeCare.

E. ABC introduces background checks on information security performance for all suppliers.

F. ABC periodically monitors compliance with all applicable legislation and contractual requirements involving third parties.

B. This option is a possible correction and corrective action that ABC could take to address the nonconformity. A correction is the action taken to eliminate a detected nonconformity, while a corrective action is the action taken to eliminate the cause of a nonconformity and to prevent its recurrence1. By cancelling the service agreement with WeCare, ABC could stop the unauthorized use of residents’ personal data and protect their privacy and rights. This could also prevent further complaints and legal issues from the residents and their family members. However, this option may also have some drawbacks, such as the loss of a service provider, the need to find an alternative solution, and the potential impact on the residents’ well-being.

E. This option is a possible corrective action that ABC could take to address the nonconformity. By introducing background checks on information security performance for all suppliers, ABC could ensure that they select and work with reliable and trustworthy partners who respect the confidentiality, integrity, and availability of the information they handle. This could also help ABC to comply with information security control A.15.1.1 (Information security policy for supplier relationships), which requires the organisation to agree and document information security requirements for mitigating the risks associated with supplier access to the organisation’s assets2.

F. This option is a possible corrective action that ABC could take to address the nonconformity. By periodically monitoring compliance with all applicable legislation and contractual requirements involving third parties, ABC could verify that the suppliers are fulfilling their obligations and responsibilities regarding information security. This could also help ABC to comply with information security control A.18.1.1 (Identification of applicable legislation and contractual requirements), which requires the organisation to identify, document, and keep up to date the relevant legislative, regulatory, contractual, and other requirements to which the organisation is subject3.

These three options represent valid audit trails for control 5.7, as they are aligned with the control’s requirements and objectives. According to the web search results from my predefined tool, control 5.7 requires organisations to collect and analyse information relating to information security threats and use that information to take mitigation actions12. The control also specifies that threat intelligence should be relevant, perceptive, contextual, and actionable, and that it should be used to prevent, detect, or respond to threats34. Therefore, the auditor should verify how the organisation collects, analyses, and produces threat intelligence, how it uses threat intelligence to protect its information assets, and how it monitors and evaluates the effectiveness of its threat intelligence arrangements. The other options are not valid audit trails, as they are either irrelevant, incorrect, or incomplete. For example:

•The task of producing threat intelligence is not assigned to the organisation’s internal audit team, but to the person or team responsible for the ISMS, such as the information security manager or the information security committee5 .

•The organisation’s risk assessment process does not begin with effective threat intelligence, but with the identification of the context, scope, and objectives of the ISMS . Threat intelligence is an input for the risk identification and analysis, but not the starting point of the risk assessment process.

•Speaking to top management to make sure all staff are aware of the importance of reporting threats is not sufficient to audit the control, as it does not address how the organisation collects, analyses, and produces threat intelligence, nor how it uses it to take mitigation actions. The auditor should also speak to the staff involved in the threat intelligence process, and review the relevant documents and records.

•Checking that the organisation has a fully documented threat intelligence process is not enough to audit the control, as it does not verify the implementation and effectiveness of the process. The auditor should also observe the process in action, and examine the outputs and outcomes of the process.

•Determining whether internal and external sources of information are used in the production of threat intelligence is a partial audit trail, as it only covers one aspect of the control. The auditor should also assess the quality, reliability, and relevance of the sources, and how the information is analysed and used.

The audit team used technical verification, making option B the correct answer. Technical verification involves examining technical configurations, system settings, or operational characteristics of information systems to verify whether controls are implemented and effective. In this scenario, the auditors examined server logs to determine whether they could be altered or deleted, which directly assesses the technical enforcement of logging controls.

ISO/IEC 27002:2022 control 8.15 requires organizations to ensure that logs are protected against unauthorized modification or deletion. Verifying this requirement cannot be achieved through interviews or documentation alone; it requires direct interaction with or inspection of the technical system.

Option A is incorrect because analysis refers to evaluating information, patterns, or results after evidence has been collected, not to the act of examining system configurations. Option C is incorrect because observation involves watching activities or processes being performed, such as monitoring staff behavior or physical security practices, not inspecting system-level controls.

Therefore, reviewing server logs for editability or deletion capability is a clear example of technical verification, which is an appropriate and necessary audit procedure for technological controls.

Based on the provided scenario, the auditors’ request for documentary evidence regarding the monitoring process of outsourced operations indicates that the auditors demonstrated professional skepticism. This is because professional skepticism involves a critical assessment of audit evidence and includes a questioning mind and a careful evaluation of the information provided by the auditee123.

Professional skepticism is an essential part of the auditing process, especially in the context of ISO/IEC 27001, which requires auditors to systematically examine an organization’s information security risks, including the management of outsourced processes4. The auditors’ request for evidence suggests that they were not satisfied with verbal assurances alone and sought to verify that SendPay had a formal, documented process for monitoring outsourced activities, which is a requirement for maintaining an effective Information Security Management System (ISMS)5.

Therefore, the correct answer is: A. The auditors demonstrated professional skepticism.

The correct sequence of activities for the management of information security risk in accordance with the requirements of ISO/IEC 27001:2022 is as follows:

1st: Create and maintain information security risk criteria 2nd: Identify the risks that need to be considered when planning for the information security management system 3rd: Assess the potential consequences that would arise if the risk were to materialise 4th: Select appropriate risk treatment options 5th: Carry out information security risk assessments at planned intervals 6th: Consider the results of risk assessment and the status of the risk treatment plan at management review

This sequence is based on the information security risk management process described in ISO/IEC 27001:2022 clause 6.1, which includes the following activities:

establishing and maintaining information security risk criteria;

ensuring that repeated information security risk assessments produce consistent, valid and comparable results;

identifying the information security risks;

analyzing the information security risks;

evaluating the information security risks;

treating the information security risks;

accepting the information security risks and the residual information security risks;

communicating and consulting with stakeholders throughout the process;

monitoring and reviewing the information security risks and the risk treatment plan.
