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(which affects the motivation and satisfaction of the organization’s personnel), and a fall in productivity linked to outdated production equipment (which affects the efficiency and quality of the organization’s processes)2.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

Comprehensive and Detailed In-Depth Explanation:

B. Correct Answer:

Qualitative evidence assesses whether processes comply with audit criteria based on descriptive, observational, and interview-based data.

Quantitative evidence uses numerical data (e.g., metrics, statistics, or performance indicators) to assess if a process is functional and effective.

A. Incorrect:

Qualitative evidence is not limited to sampling and quantitative evidence is based on measurable data.

C. Incorrect:

Qualitative evidence does not estimate populations; it is subjective and descriptive.

Relevant Standard Reference:

ISO 19011:2018 Clause 6.4.7 (Types of Audit Evidence: Qualitative vs. Quantitative)

The Act phase of the PDCA cycle is where the organisation takes actions to improve its processes and performance based on the results of the Check phase. This may involve resetting objectives to make them more realistic, achievable or challenging, or implementing changes to address the root causes of problems and achieve the desired outcomes. The Act phase is also where the organisation monitors the effects of the actions taken and evaluates their effectiveness and efficiency. The Act phase is important because it enables the organisation to learn from its experience and continually improve its ISMS. References: What is ‘Plan, Do, Check, Act’?

This option is appropriate for inclusion in the closing meeting agenda, as it is a requirement of the ISO 19011 standard, which provides guidelines for auditing management systems, including ISMS12. The standard states that the audit team leader should advise the auditee of any situations encountered during the audit that may decrease the confidence that can be placed in the audit conclusions, such as limitations in the audit scope, access, or sampling3. The standard also states that the audit report should include a statement that the audit is based on a sample of the information available at the time of the audit, and that the audit does not provide absolute assurance of the conformity or effectiveness of the audited management system4. Therefore, the audit team leader should include a disclaimer in the closing meeting agenda to inform the auditee of the nature and limitations of the audit, and to avoid any misunderstandings or false expectations. The other options are not appropriate for inclusion in the closing meeting agenda, as they are either irrelevant, incorrect, or incomplete. For example:

•A detailed explanation of the certification body’s complaints process is not relevant for the closing meeting agenda, as it is not related to the audit findings or conclusions. The certification body’s complaints process should be communicated to the auditee before the audit, as part of the audit agreement or contract5.

•An explanation of the audit plan and its purpose is not correct for the closing meeting agenda, as it should have been done at the opening meeting or before the audit. The audit plan is a document that describes the scope, objectives, criteria, and methodology of the audit, as well as the audit schedule, the audit team, the audit locations, and the audit deliverables . The audit plan should be communicated and agreed with the auditee in advance, and any changes or deviations should be notified during the audit.

•Names of auditees associated with nonconformities are not complete for the closing meeting agenda, as they do not provide the details or the evidence of the nonconformities. The audit team leader should present the audit findings, which include the description, the audit criteria, and the audit evidence of each nonconformity, as well as the audit conclusions and the audit recommendation . The audit team leader should also avoid naming or blaming individuals, and focus on the processes and the system.

The role and responsibility that system users should not observe in the event of an information security incident is D: make the information security incident details known to all employees. This is not a proper role or responsibility for system users, as it could cause unnecessary panic, confusion or speculation among employees who are not involved in the incident response process. It could also compromise the confidentiality and integrity of the incident information, which could be sensitive or confidential in nature. Making the information security incident details known to all employees could also violate the information security policies and procedures of the organization, which may require a certain level of discretion and confidentiality when dealing with incidents. The other roles and responsibilities are correct, as they describe what system users should do in the event of an information security incident, such as reporting the incident to the Servicedesk (A), preserving evidence if necessary (B), and cooperating with investigative personnel if needed ©. These roles and responsibilities help to ensure a quick, effective and orderly response to information security incidents. ISO/IEC 27001:2022 requires the organization to implement procedures for reporting and managing information security incidents (see clause A.16.1). References: CQI & IRCA Certified ISO/IEC 27001:2022 Lead Auditor Training Course, ISO/IEC 27001:2022 Information technology — Security techniques — Information security management systems — Requirements, What is Information Security Incident Management?

The words that best complete the sentence are assess and recommendation. The sentence would read as follows:

“An audit plan is a statement of the intent of the audit team to assess all areas of the company with a view to determining a recommendation for certification approval.”

According to the web search results from my predefined tool, a third-party audit plan is a document that describes the scope, objectives, criteria, and methodology of an external audit conducted by an independent certification body to verify the conformity of an organization’s ISMS with the ISO 27001 standard12. The audit plan also includes the audit schedule, the audit team, the audit locations, and the audit deliverables23. One of the main deliverables of a third-party audit is the audit report, which summarizes the audit findings, the audit conclusions, and the audit recommendation34. The audit recommendation is the opinion of the audit team on whether the organization’s ISMS meets the certification requirements and whether the certification should be granted, maintained, suspended, or withdrawn45.

Therefore, the purpose of the audit plan is to state the intention of the audit team to assess all areas of the company, meaning to evaluate the performance and effectiveness of the ISMS, and to determine a recommendation for certification approval, meaning to provide a judgment on the certification status of the ISMS. The other words in the options, such as verdict, permit, report, inspect, and question, do not accurately reflect the meaning of the audit plan. A verdict is a formal decision made by a judge or a jury, not by an audit team. A permit is a legal authorization to do something, not a certification of conformity. A report is a document that presents the audit results, not the audit intention. An inspection is a visual examination of something, not a comprehensive assessment of an ISMS. A question is a request for information, not a determination of a recommendation.

According to ISO 19011:2018, clause 5.3, the person responsible for managing the audit programme should determine the resources necessary for the audit programme, such as the audit team members, the budget, the time, the tools, etc. The audit resources should be sufficient and appropriate to ensure the quality and effectiveness of the audit programme and the audit results. The audit resources include the following elements12:

Essential resources: These are the resources that are required to conduct the audit programme and the individual audits, such as the audit documents, the audit methods, the audit tools, the audit schedule, the audit budget, etc. The essential resources should be identified and allocated based on the audit objectives, scope, and criteria, and the availability and cooperation of the auditee. The essential resources should also be reviewed and updated as necessary to reflect any changes or deviations in the audit programme or the individual audits.

Competent personnel: These are the audit team members who have the appropriate knowledge, skills, and experience to conduct the audit effectively and efficiently, and to provide credible and reliable audit results and recommendations. The competent personnel should include the audit team leader, the auditors, and any technical experts or observers who support the audit team. The competent personnel should be selected and appointed based on the audit objectives, scope, and criteria, and the specific competence requirements for the audit programme and the individual audits. The competent personnel should also be independent and impartial, and avoid any conflicts of interest or self-interest that may affect the audit results or the audit decisions.

Audit planning for certification audits is defined by ISO 19011:2018, clause 6.3 (Preparing audit activities) and ISO/IEC 27006.

Key audit planning documents include:

Audit plan (mandatory, prepared by team leader)

Checklists (supporting tool for consistency and coverage of requirements)

List of external providers (required to check compliance with ISO/IEC 27001 Annex A.5.19 – supplier relationships and A.5.20 – supplier agreements)

Sample plans (used when sampling evidence across sites, processes, or records is needed, especially in Stage 2 audits)

However, the following are not required:

B. Career history of the IT manager – Personnel competence may be verified during interviews and evidence review, but an auditor does not need career histories as part of audit planning. ISO 19011 only requires access to competence records if needed but not CVs.

F. Organisation’s financial statement – Financial performance is not part of ISMS audit planning unless it relates to identified risks or contractual obligations. ISO/IEC 27001 focuses on information security risks, not financial audit compliance.

ISO 19011:2018 (clause 6.3.2) clearly defines the required planning inputs as:

Audit objectives, scope, and criteria

Audit team roles and responsibilities

Allocation of resources

Information about the auditee’s ISMS (e.g., documented scope, processes, external provider relationships, relevant legal/regulatory requirements)

There is no mention of personnel CVs or financial statements being required.

Final Correct Answer: B and F

The correct answer is A, because internal and external audits serve different but complementary purposes within an ISO/IEC 27001-based ISMS. Internal audits are conducted by or on behalf of the organization to regularly assess the effectiveness, conformity, and continual improvement of the ISMS. Their results help management identify weaknesses, risks, and opportunities for improvement before they become systemic issues.

ISO/IEC 27001 requires organizations to conduct internal audits at planned intervals to ensure the ISMS conforms to both internal requirements and the standard. These audits provide valuable input into management reviews, corrective actions, and readiness for external audits. In this way, internal audits act as an early warning and improvement mechanism.

External audits, conducted by an independent certification body, rely partly on the maturity demonstrated through internal audit outcomes. They verify whether the organization’s ISMS meets ISO/IEC 27001 requirements and whether internal audits are effective and properly implemented.

Option B is incorrect because internal audits are not passive reviews of external audit outputs; they are independent assessments with their own scope and objectives. Option C is incorrect because the roles are reversed: internal audits focus on ongoing internal improvement, while external audits focus on certification conformity.

Therefore, internal audits directly support and complement external audits by strengthening ISMS readiness and effectiveness.

Comprehensive and Detailed In-Depth Explanation:

B. Correct Answer:

ISO/IEC 27001:2022 Clause 6.1.3 (Information Security Risk Treatment) requires that any decision to accept risk be documented and justified.

Failure to document this decision creates compliance and audit tracking gaps.

A. Incorrect:

Risk acceptance must always be documented for accountability.

C. Incorrect:

Organizations are not required to mitigate every nonconformity but must justify their risk acceptance.
