The benefits of implementing an ISMS primarily result from a reduction in information security risks. E. The purpose of an ISMS is to apply a risk management process for preserving information security.
Comprehensive and Detailed Explanation: According to the ISO 27001 standard, the benefits of implementing an ISMS include the following1:
* Assuring customers and other stakeholders of the confidentiality, integrity and availability of information
* Enhancing the ability to respond to information security incidents and minimize their impacts
* Improving the governance and management of information security
* Reducing the costs and losses associated with information security breaches
* Increasing the competitiveness and reputation of the organization
* Complying with legal, regulatory and contractual obligations The purpose of an ISMS is to provide a systematic approach to managing information security risks, based on the Plan-Do-Check-Act (PDCA) cycle1. The ISMS enables the organization to establish, implement, maintain and continually improve its information security performance, in alignment with its business objectives and the needs and expectations of interested parties1. The ISMS consists of the following elements1:
* The information security policy and objectives
* The scope and boundaries of the ISMS
* The processes and procedures for information security risk assessment and treatment
* The resources and competencies for information security
* The roles and responsibilities for information security
* The performance evaluation and improvement of the ISMS
* The internal and external communication and awareness of the ISMS References:

Explanation:

The word that best completes the sentence is "demonstrate". According to ISO/IEC 27001:2022, Clause 7.5, the organization shall retain documented information as evidence of the performance of the processes and the conformity of the products and services with the requirements1. The purpose of retaining documented information is to demonstrate conformity with the requirements of the management system standard, not to maintain, audit, or certify it.

Explanation
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.
