ISO-IEC-27001-Lead-Auditor Reviews Questions

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.

According to ISO/IEC 27001, organizations must control planned changes and review the consequences of unintended changes in order to ensure continued alignment with information security requirements. In this scenario, the organization failed to perform appropriate testing after an emergency update to the mobile app, which constitutes a nonconformity with clause 8.1 of the standard.

ISO/IEC 27001 requires that organizations adhere to their established procedures for software security management. The IT Manager's approval of the app despite failed security tests and lack of proper documentation for the new version indicates noncompliance with the procedure, thus reflecting a nonconformity.

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), clause 4.1 requires an organization to determine external and internal issues that are relevant to its purpose and that affect its ability to achieve the intended outcomes of its ISMS2. External issues are those that originate from outside the organization, such as legal, regulatory, cultural, social, political, economic, natural and competitive factors2. Internal issues are those that originate from within the organization, such as governance, structure, roles and responsibilities, policies, objectives, culture, capabilities, resources and information systems2. Therefore, based on this definition, four examples of external issues in the context of a management system to ISO/IEC 27001:2022 are a rise in interest rates in response to high inflation (which affects the economic environment of the organization), a reduction in grants as a result of a change in government policy (which affects the political and legal environment of the organization), higher labour costs as a result of an aging population (which affects the social and demographic environment of the organization), and inability to source raw materials due to government sanctions (which affects the trade and supply environment of the organization)2. The other options are examples of internal issues, as they originate from within the organization or its activities. For example, poor levels of staff competence as a result of cuts in training expenditure (which affects the capabilities and resources of the organization), increased absenteeism as a result of poor management (which affects the culture and performance of the organization), poor morale as a result of staff holidays being reduced (which affects the motivation and satisfaction of the organization’s personnel), and a fall in productivity linked to outdated production equipment (which affects the efficiency and quality of the organization’s processes)2. References: ISO/IEC 27001:2022 - Information technology – Security techniques – Information security management systems – Requirements

According to ISO/IEC 27001 standards, if the auditee decides to accept the risk instead of implementing corrective actions for a nonconformity, this decision should be justified and documented. Documenting such decisions is essential for maintaining the integrity of the ISMS and for demonstrating that the decision was made based on informed judgment.
