An Information Security Management System (ISMS) is a systematic approach to managing the security of information assets within an organization. It includes the policies, processes, and controls that address the risks and opportunities related to information security. An ISMS is based on the Plan-Do-Check-Act (PDCA) cycle, which consists of four phases: establishment, implementation, operation, and maintenance. Therefore, an ISMS is set up in the following order: establishment, implementation, operation, maintenance. Reference: ISO/IEC 27000:2022, clause 3.24; ISO/IEC 27001:2022, clause 4.

Explanation
An asset register is a document that contains information about the assets associated with information and information processing facilities within the scope of the information security management system. An asset register should include, among other things, the asset type and the asset owner. The asset type is a category or classification of the asset, such as hardware, software, data, document, service, etc. The asset owner is a person or entity that has been assigned the responsibility for managing and protecting the asset throughout its lifecycle. The asset type and the asset owner are important information for identifying and controlling the assets, as well as for performing risk assessments and applying security controls. ISO/IEC 27001:2022 requires the organization to maintain an inventory of assets within the scope of the information security management system (see clause A.8.1.1).

The three options that would not be valid audit trails are:
*Collect more evidence on how the organisation manages the Point of Contact (PoC) which monitors vulnerabilities. (Relevant to clause 8.1)
*Collect more evidence on whether terms and definitions are contained in the information security policy.
(Relevant to control 5.32)
*Collect more evidence to determine if ISO 27035 (Information security incident management) is used as internal audit criteria. (Relevant to clause 8.13) These options are not valid audit trails because they are not directly related to the information security incident management process, which is the focus of the audit. The audit trails should be relevant to the objectives, scope, and criteria of the audit, and should provide sufficient and reliable evidence to support the audit findings and conclusions1.
Option E is not valid because the PoC is not a part of the information security incident management process, but rather a role that is responsible for reporting and escalating information security incidents to the appropriate authorities2. The audit trail should focus on how the PoC performs this function, not how the organisation manages the PoC.
Option G is not valid because the terms and definitions are not a part of the information security incident management process, but rather a part of the information security policy, which is a high-level document that defines the organisation's information security objectives, principles, and responsibilities3. The audit trail should focus on how the information security policy is communicated, implemented, and reviewed, not whether it contains terms and definitions.
Option H is not valid because ISO 27035 is not a part of the information security incident management process, but rather a guidance document that provides best practices for managing information security incidents4. The audit trail should focus on how the organisation follows the requirements of ISO/IEC
27001:2022 for information security incident management, not whether it uses ISO 27035 as an internal audit criteria.
The other options are valid audit trails because they are related to the information security incident management process, and they can provide useful evidence to evaluate the conformity and effectiveness of the process. For example:
*Option A is valid because it relates to control A.5.29, which requires the organisation to establish procedures to isolate and quarantine areas subject to information security incidents, in order to prevent further damage and preserve evidence5. The audit trail should collect evidence on how the organisation implements and tests these procedures, and how they ensure the continuity of information security during disruption.
*Option B is valid because it relates to control A.6.8, which requires the organisation to establish mechanisms for reporting information security events and weaknesses, and to ensure that they are communicated in a timely manner to the appropriate levels within the organisation6. The audit trail should collect evidence on how the organisation defines and uses these mechanisms, and how they monitor and review the reporting process.
*Option C is valid because it relates to clause 7.2, which requires the organisation to provide information security awareness, education, and training to all persons under its control, and to evaluate the effectiveness of these activities7. The audit trail should collect evidence on how the organisation identifies the information security training needs, how they deliver and record the training, and how they measure the learning outcomes and feedback.
*Option D is valid because it relates to control A.5.27, which requires the organisation to learn from information security incidents and to implement corrective actions to prevent recurrence or reduce impact8.
The audit trail should collect evidence on how the organisation analyses and documents the root causes and consequences of information security incidents, how they identify and implement corrective actions, and how they verify the effectiveness of these actions.
*Option F is valid because it relates to control A.5.30, which requires the organisation to establish and maintain a business continuity plan to ensure the availability of information and information processing facilities in the event of a severe information security incident9. The audit trail should collect evidence on how the organisation develops and updates the business continuity plan, how they test and review the plan, and how they communicate and train the relevant personnel on the plan.

Explanation
The three options for findings that are justified in the scenario are:
*Nonconformity (NC) - The information for the acceptance of residual information security risks should be updated after the risk treatment is implemented. Clause 6.1.3.f
*Nonconformity (NC) - The IT security manager should be aware of and understand his authority and area of responsibility. Clause 7.3
*Nonconformity (NC) - The risk treatment plan No. 123 should be approved by the risk owner, the Facility Manager in this case. Clause 6.1.3.f According to ISO/IEC 27001:2022, clause 6.1.3.f, the organisation must retain documented information that includes the information for the acceptance of residual information security risks, and the approval of the risk treatment plan by the risk owner1. Therefore, option A and G are justified as nonconformities, because the organisation failed to update the information for the acceptance of residual risks, and the risk treatment plan was approved by the IT security manager, who is not the risk owner.
According to ISO/IEC 27001:2022, clause 7.3, the organisation must ensure that the persons assigned to perform the roles and responsibilities for the ISMS are competent, and are aware of the consequences of not conforming to the ISMS requirements2. Therefore, option E is justified as a nonconformity, because the IT security manager, who is responsible for the information security risk management process, was not aware of his authority and area of responsibility.
The other options are not justified as findings, because they are either irrelevant or incorrect. For example:
*Option B is irrelevant, because it is not related to the information security risk treatment plan No. 123, which is the focus of the audit.
*Option C is incorrect, because it is not an opportunity for improvement, but rather a benefit of the risk treatment plan No. 123, which is already implemented.
*Option D is incorrect, because it is not a nonconformity, but rather a requirement for the organisation to provide the resources needed for the ISMS, which is not the same as the resources needed for the risk treatment plan No. 123.
*Option F is incorrect, because it is not a nonconformity, but rather a requirement for the organisation to provide the resources needed for the continual improvement of the ISMS, which is not the same as the resources needed for the risk treatment plan No. 123.
*Option H is irrelevant, because it is not a finding, but rather a good practice, which is not the objective of the audit.

According to ISO 19011:2018, which provides guidelines for auditing management systems, an audit programme is a set of one or more audits planned for a specific time frame and directed towards a specific purpose1. The individual(s) managing the audit programme are responsible for establishing, implementing and maintaining the audit programme in accordance with the organization's policies and objectives1. This includes defining the extent of the audit programme based on strategic direction, risks and opportunities; establishing the audit programme by defining its objectives, scope and criteria; determining the resources necessary for the audit programme; selecting competent auditors and assigning them to appropriate audits; defining the objectives, scope and criteria for each individual audit; defining the plan of each individual audit; retaining documented information of the audit results; reviewing and improving the performance of the audit programme1. Therefore, these six actions are part of the responsibilities of the individual(s) managing the audit programme. The other option, communicating with the auditee during the audit, is not a responsibility of the individual(s) managing the audit programme, but rather a responsibility of the audit team leader1.
