The purpose of a management system audit is to evaluate the performance of an organization’s management system.

A management system audit is an independent and systematic analysis and evaluation of a company’s overall activities and performances1. It is a valuable tool used to determine the efficiency, functions, accomplishments and achievements of the company1. A management system audit can be conducted against a range of audit criteria, including (but not limited to) requirements set of in existing ISO standards2.

According to ISO 19011:2018, which provides guidelines for auditing management systems, the purpose of an audit is to enable the auditor to provide an audit conclusion that is related to the audit objectives2. The audit objectives are defined by the audit client and may include determining the extent of conformity or nonconformity of the audited management system against the audit criteria, evaluating the ability of the audited management system to ensure that the organization meets applicable statutory, regulatory and contractual requirements, identifying potential improvement opportunities for the audited management system, and facilitating continual improvement of the audited management system2.

Therefore, the correct answer is evaluate, as it best describes the purpose of a management system audit. The other options are not correct because they are not specific enough or do not reflect the intended outcome of an audit. For example, improve implies that the audit itself will enhance the performance of the management system, which is not necessarily true. Manage implies that the audit will control or direct the management system, which is not its role. Research implies that the audit will generate new knowledge or information about the management system, which is not its primary aim.

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. References: 1: ISO/IEC 27001:2022, Information technology — Security techniques — Information security management systems — Requirements, Clause 7.5

The two standards that are used as ISMS third-party certification audit criteria are ISO/IEC 27001 and relevant legal, statutory, and regulatory requirements. ISO/IEC 27001 specifies the requirements for establishing, implementing, maintaining, and continually improving an information security management system (ISMS)1. Relevant legal, statutory, and regulatory requirements are those that apply to the organization’s information security aspects and objectives2. The other options are either not standards (E) or not directly related to the ISMS certification audit criteria (A, B, C, F). References: 1: ISO/IEC 27001:2022, Information technology — Security techniques — Information security management systems — Requirements, Clause 1 \n2: ISO/IEC 27001:2022, Information technology — Security techniques — Information security management systems — Requirements, Clause 4.2

The use of new technologies such as big data presents new challenges in auditing, particularly the issue of combining structured and unstructured data. Big data environments often include diverse data sets that auditors need to understand and interpret, which requires new skills and approaches to ensure effective and comprehensive audit coverage.

The correct answers for matching each of the descriptions with the appropriate risk term are:

• The strategy chosen to respond to a specific information security risk: This is a definition of information security risk treatment. According to ISO/IEC 27000:2022, information security risk treatment is “the process of selecting and implementing measures to modify the information security risk” Section 3.33.
• The effect of uncertainty on information security objectives: This is a definition of information security risk. According to ISO/IEC 27000:2022, information security risk is “the effect of uncertainty on information security objectives” Section 3.32.
• The requirements against which information security risks are evaluated: This is a definition of information security risk criteria. According to ISO/IEC 27000:2022, information security risk criteria are “the terms of reference by which the significance of information security risks is assessed” Section 3.31.
• A definition of the overall level of information security risk that is considered to be tolerable: This is a definition of information security risk acceptance criteria. According to ISO/IEC 27000:2022, information security risk acceptance criteria are “the level of information security risk that is acceptable” Section 3.30.

According to the PECB Candidate Handbook for ISO/IEC 27001 Lead Auditor, the auditee should take the following actions in response to a nonconformity against clause 6.1.3.e of ISO/IEC 27001:20221:

• Implement the appropriate risk treatment for each of the applicable controls, as this is the main requirement of clause 6.1.3.e and the objective of the risk treatment process2.
• Revise the relevant content in the Statement of Applicability to justify their exclusion, as this is the expected output of the risk treatment process and the evidence of the risk-based decisions3.
• Revisit the risk assessment process relating to the three controls, as this is the input for the risk treatment process and the source of identifying the risks and the controls4.

The other options are not correct because:

• Allocating responsibility for producing evidence to prove to auditors that the controls are implemented is not a valid action, as the audit team already found that there was no evidence of the implementation of the three controls.
• Compiling plans for the periodic assessment of the risks associated with the controls is not a valid action, as this is part of the risk monitoring and review process, not the risk treatment process5.
• Incorporating written procedures for the controls into the organisation’s Security Manual is not a valid action, as this is part of the documentation and operation of the ISMS, not the risk treatment process.
• Removing the three controls from the Statement of Applicability is not a valid action, as this is not a sufficient justification for their exclusion and does not reflect the risk treatment process.
• Undertaking a survey of customers to find out if the controls are needed by them is not a valid action, as this is not a relevant criterion for the risk assessment and treatment process, which should be based on the organisation’s own context and objectives.

The audit procedure used here is "analysis." The audit team analyzed server logs to verify if they can be edited or deleted, focusing on evaluating the logs' properties and the controls over their manipulation to ensure they comply with ISO/IEC 27001 requirements.

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), clause 5.2 requires top management to establish an information security policy that provides the framework for setting information security objectives1. Clause 6.2 requires top management to ensure that the information security objectives are established at relevant functions and levels1. Therefore, when verifying that the information security policy and objectives have been established by top management, an ISMS auditor should review relevant documents and records that demonstrate top management’s involvement and commitment.

To verify that the mobile device policy and objectives are implemented and effective, an ISMS auditor should review relevant documents and records that demonstrate how the policy and objectives are communicated, monitored, measured, analyzed, and evaluated. The auditor should also sample and verify the implementation of the controls that are stated in the policy.

Three options for the audit trail that are relevant to verifying the mobile device policy and objectives are:

• Review the internal audit report to make sure the IT department has been audited: This option is relevant because it can provide evidence of how the IT department, which is responsible for managing the mobile devices and their security, has been evaluated for its conformity and effectiveness in implementing the mobile device policy and objectives. The internal audit report can also reveal any nonconformities, corrective actions, or opportunities for improvement related to the mobile device policy and objectives.
• Sampling some mobile devices from on-duty medical staff and validate the mobile device information with the asset register: This option is relevant because it can provide evidence of how the mobile devices that are used by the medical staff, who are involved in processing and storing residents’ data, are registered in the asset register and have physical protection enabled. This can verify the implementation and effectiveness of two of the controls that are stated in the mobile device policy.
• Review the asset register to make sure all company’s mobile devices are registered: This option is relevant because it can provide evidence of how the company’s mobile devices that are within the ISMS scope are identified and accounted for. This can verify the implementation and effectiveness of one of the controls that are stated in the mobile device policy.

The other options for the audit trail are not relevant to verifying the mobile device policy and objectives, as they are not related to the policy or objectives or their implementation or effectiveness. For example:

• Interview the reception personnel to make sure all visitor and employee bags are checked before entering the nursing home: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding physical security or access control, but not specifically to mobile devices.
• Review visitors’ register book to make sure no visitor can have their personal mobile phone in the nursing home: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding information security awareness or compliance, but not specifically to mobile devices.
• Interview the supplier of the devices to make sure they are aware of the ISMS policy: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding information security within supplier relationships, but not specifically to mobile devices.
• Interview top management to verify their involvement in establishing the information security policy and the information security objectives: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to verifying that the information security policy and objectives have been established by top management, but not specifically to mobile devices.
