ISO-IEC-27001-Lead-Auditor PECB Certified ISO/IEC 27001 2022 Lead Auditor exam Free Practice Exam Questions (2026 Updated)

The correct options for how the auditor should respond are:

A. Advise the MSR that an extension of the scope may be incorporated but will have to go through established procedures

D. Determine whether the Management System covers the processes at the new site and, if so, proceed with the audit

These options are consistent with the ISO/IEC 27006:2015 standard, which states that any changes to the scope of certification should be notified by the client to the certification body, and that the certification body should evaluate and decide on these changes in accordance with its procedures1. The auditor should also verify that the ISMS is implemented and maintained at all sites included in the scope of certification1.

The other options are not appropriate for how the auditor should respond, because:

B. Advise the MSR that the audit scope has been determined based on their initial application so the audit has to proceed as planned: This option is too rigid and does not allow for any flexibility or adaptation to the client’s situation. The auditor should be open to consider any changes to the scope of certification that may have occurred since the initial application, as long as they are properly notified and evaluated by the certification body.

C. Suggest that the MSR cancels the audit contract and reapplies for the new situation: This option is too drastic and unnecessary, as it would cause delays and costs for both the client and the certification body. The auditor should not suggest that the client cancels the audit contract, but rather that they follow the established procedures for requesting and approving an extension of the scope of certification.

E. Advise the MSR that, within the existing scope, the new work area can be included without any problem: This option is too lenient and does not ensure that the new work area meets the requirements of ISO/IEC 27001 and the ISMS. The auditor should not assume that the new work area can be included within the existing scope without any problem, but rather that they need to verify that the ISMS is implemented and maintained at the new site, and that any changes to the scope of certification are approved by the certification body.

F. Confirm that the auditor will advise the auditee that the audit scope will be revised to include the new work area: This option is too presumptuous and does not respect the authority of the certification body. The auditor should not confirm that they will revise the audit scope to include the new work area, but rather that they will advise the certification body of the client’s request for an extension of the scope of certification, and wait for their decision.

Comprehensive and Detailed In-Depth Explanation:

A. Correct Answer:

Techmanic misrepresented its certification scope, which is a violation of ISO certification rules.

Suspension allows time for corrective action before withdrawal is considered.

B. Incorrect:

Certification withdrawal is only necessary if corrective actions fail after suspension.

C. Incorrect:

Transfer does not resolve misrepresentation issues.

Relevant Standard Reference:

ISO/IEC 17021-1:2015 Clause 9.6.5 (Certification Suspension and Misrepresentation Issues)

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)

No, copies of files are not generally kept as audit records unless specifically required and agreed upon in the audit plan. Audit records typically include notes and observations made by auditors, not copies of the auditee's files, unless these are essential and explicitly allowed by the auditee.

The correct order of the stages is:

Prepare the audit checklist

Gather objective evidence

Review audit evidence

Document findings

Audit preparation: This stage involves defining the audit objectives, scope, criteria, and plan. The auditor also prepares the audit checklist, which is a list of questions or topics that will be covered during the audit. The audit checklist helps the auditor to ensure that all relevant aspects of the ISMS are addressed and that the audit evidence is collected in a systematic and consistent manner12.

Audit execution: This stage involves conducting the audit activities, such as opening meeting, interviews, observations, document review, and closing meeting. The auditor gathers objective evidence, which is any information that supports the audit findings and conclusions. Objective evidence can be qualitative or quantitative, and can be obtained from various sources, such as records, statements, physical objects, or observations123.

Audit reporting: This stage involves reviewing the audit evidence, evaluating the audit findings, and documenting the audit results. The auditor reviews the audit evidence to determine whether it is sufficient, reliable, and relevant to support the audit findings. The auditor evaluates the audit findings to determine the degree of conformity or nonconformity of the ISMS with the audit criteria. The auditor documents the audit results in an audit report, which is a formal record of the audit process and outcomes. The audit report typically includes the following elements123:

An introduction clarifying the scope, objectives, timing and extent of the work performed

An executive summary indicating the key findings, a brief analysis and a conclusion

The intended report recipients and, where appropriate, guidelines on classification and circulation

Detailed findings and analysis

Recommendations for improvement, where applicable

A statement of conformity or nonconformity with the audit criteria

Any limitations or exclusions of the audit scope or evidence

Any deviations from the audit plan or procedures

Any unresolved issues or disagreements between the auditor and the auditee

A list of references, abbreviations, and definitions used in the report

A list of appendices, such as audit plan, audit checklist, audit evidence, audit team members, etc.

Audit follow-up: This stage involves verifying the implementation and effectiveness of the corrective actions taken by the auditee to address the audit findings. The auditor monitors the progress and completion of the corrective actions, and evaluates their impact on the ISMS performance and conformity. The auditor may conduct a follow-up audit to verify the corrective actions on-site, or may rely on other methods, such as document review, remote interviews, or self-assessment by the auditee. The auditor documents the follow-up results and updates the audit report accordingly123.

•Second-Party Audits: These involve an organization (the customer) auditing another organization with which it has a relationship (such as a supplier). The focus is on ensuring the supplier meets the customer's information security requirements.

•Accreditation Bodies: These assess the competence of certification bodies but don't directly participate in second-party audits.

•CQI and IRCA: These organizations provide auditor certifications but their training alone doesn't automatically qualify someone for second-party ISO/IEC 27001 audits. The auditor should have specific knowledge of the standard.

Comprehensive and Detailed In-Depth Explanation:

The CIA Triad (Confidentiality, Integrity, and Availability) is the foundation of information security principles.

Availability ensures that data and services are accessible when needed. By implementing regular, automated backups and offsite storage, the organization ensures that critical data remains accessible even after a security incident (e.g., data loss, cyberattacks, or hardware failures). This aligns with ISO/IEC 27001:2022 Annex A Control A.8.13 (Information Backup), which emphasizes maintaining and testing backups to ensure system resilience.

Integrity ensures that data remains unaltered and accurate, but backups do not inherently enforce integrity unless accompanied by checksum or validation mechanisms.

Confidentiality ensures that only authorized users can access data, which is not the primary goal of a backup procedure.

A. Advise the Shipping Manager that his request will be included in the audit report. This is true because the audit report should document all the relevant information and evidence related to the audit, including any requests or objections raised by the auditee. The audit report should also provide the rationale for the audit conclusions and recommendations12.

B. Advise management that the new information provided will be discussed when the auditors have more time. This is true because the auditors should not make hasty decisions based on incomplete or unverified information. The auditors should review and evaluate the new information in a systematic and objective manner, and determine whether it affects the audit findings, nonconformities, or conclusions12.

F. Thank the Shipping Manager for his honesty but advise that withdrawing the nonconformity is not the right way to proceed. This is true because the auditors should acknowledge and appreciate the cooperation and transparency of the auditee, but also maintain their professional integrity and independence. The auditors should not withdraw a nonconformity unless they are satisfied that it was raised in error or that it has been effectively corrected and verified12.

ISO/IEC 17021-1:2022 Conformity assessment — Requirements for bodies providing audit and certification of management systems — Part 1: Requirements

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’? A framework for continuous improvement, PDCA in ISO27001 - Free guide to learn | Dr. Erdal Ozkaya, PECB Candidate Handbook ISO 27001 Lead Auditor (page 12)

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), clause 8.1 requires an organization to plan, implement and control its processes needed to meet ISMS requirements2. This includes determining what needs to be done, how it will be done, who will do it, when it will be done, what resources are required, how performance will be evaluated, etc2. Therefore, if an ISMS auditor conducting a third-party surveillance audit of a telecom’s provider notes that there has been a significant increase in the number of switches failing their initial configuration test and being returned for reprogramming due to a recent ISMS upgrade that reduced access to work instructions, this indicates a nonconformity against clause 8.1 of ISO/IEC 27001:2022. The organization has failed to plan and control its operational processes effectively to ensure information security and quality2. The other options are not correct clauses to raise a nonconformity against based solely on this information. For example, clause 7.5 deals with documented information required by ISMS or determined by an organization as necessary for its effectiveness2, but it does not specify how many copies or formats of work instructions should be available; clause 10.2 deals with nonconformity and corrective action as a response to an identified problem or incident2, but it does not address how to prevent or avoid such problems or incidents in operational processes; clause 7.3 deals with awareness of ISMS policy, objectives, roles and responsibilities among persons doing work under an organization’s control2, but it does not relate to how work instructions are accessed or followed; clause 7.2 deals with competence of persons doing work under an organization’s control that affects its ISMS performance2, but it does not imply that lack of competence is caused by insufficient work instructions; clause 7.4 deals with communication about ISMS among internal and external interested parties2, but it does not cover how operational information is communicated within an organization. References: ISO/IEC 27001:2022 - Information technology – Security techniques – Information security management systems – Requirements

The correct sequence of activities for the management of information security risk in accordance with the requirements of ISO/IEC 27001:2022 is as follows:

1st: Create and maintain information security risk criteria 2nd: Identify the risks that need to be considered when planning for the information security management system 3rd: Assess the potential consequences that would arise if the risk were to materialise 4th: Select appropriate risk treatment options 5th: Carry out information security risk assessments at planned intervals 6th: Consider the results of risk assessment and the status of the risk treatment plan at management review

This sequence is based on the information security risk management process described in ISO/IEC 27001:2022 clause 6.1, which includes the following activities:

establishing and maintaining information security risk criteria;

ensuring that repeated information security risk assessments produce consistent, valid and comparable results;

identifying the information security risks;

analyzing the information security risks;

evaluating the information security risks;

treating the information security risks;

accepting the information security risks and the residual information security risks;

communicating and consulting with stakeholders throughout the process;

monitoring and reviewing the information security risks and the risk treatment plan.

Audit evidence should be evaluated against the audit criteria in order to determine audit findings.

Audit evidence is the information obtained by the auditors during the audit process that is used as a basis for forming an audit opinion or conclusion12. Audit evidence could include records, documents, statements, observations, interviews, or test results12.

Audit criteria are the set of policies, procedures, standards, regulations, or requirements that are used as a reference against which audit evidence is compared12. Audit criteria could be derived from internal or external sources, such as ISO standards, industry best practices, or legal obligations12.

Audit findings are the results of a process that evaluates audit evidence and compares it against audit criteria13. Audit findings can show that audit criteria are being met (conformity) or that they are not being met (nonconformity). They can also identify best practices or improvement opportunities13.

Comprehensive and Detailed In-Depth Explanation:

C. Correct Answer – This is a Threat. A cyberattack exploiting a zero-day vulnerability is an active security threat, as it causes harm to the organization.

A. Employee accessing unauthorized files is a vulnerability (insider risk) rather than an external threat.

B. Lack of MFA is a security weakness (vulnerability), not a threat.

This aligns with ISO/IEC 27001:2022 Annex A Control A.8.25 (Assessment and Decision on Information Security Events).

The use of clear text passwords for authentication in FTP is a vulnerability because it is a weakness that can be exploited by threat actors. Clear text passwords can be intercepted easily by network sniffers or through man-in-the-middle attacks, making them a significant security risk1. References: = This explanation is consistent with the understanding of vulnerabilities within the field of information security, particularly as it relates to network protocols like FTP and their associated risks

The correct sequence of the steps of the audit lifecycle according to ISO 19011:2018 is:

Step 1: Audit initiation

Step 2: Audit preparation

Step 3: Conducting the audit

Step 4: Preparing and distributing the audit report

Step 5: Audit completion

Step 6: Audit follow-up

This sequence reflects the logical order of the audit activities, from establishing the audit objectives, scope and criteria, to verifying the implementation and effectiveness of the corrective actions. However, ISO 19011:2018 also recognizes that some audit activities can be iterative or concurrent, depending on the nature and complexity of the audit. For example, audit preparation and conducting the audit can overlap when new information or changes occur during the audit. Similarly, audit follow-up can be integrated with audit completion when the corrective actions are verified shortly after the audit. Therefore, the audit lifecycle should be adapted to the specific context and needs of each audit.

Regular security awareness and training sessions for employees are a control measure aimed at preventing security incidents by ensuring that personnel are aware of information security threats and concerns, and understand their roles and responsibilities in safeguarding organizational assets. This proactive approach is designed to educate employees on the importance of security practices and to avoid the occurrence of security incidents. References: = This answer is based on the principles of personnel security management as outlined in ISO/IEC 27001, particularly in Annex A.7 which deals with human resource security before, during, and after employment, and Annex A.9 which focuses on access control and ensuring that employees have access only to the information that is necessary for their job role

Sinvestment’s request to review documented information remotely during the stage 1 audit is acceptable and aligns with established auditing practices, making option A the correct answer. ISO/IEC 17021-1 and ISO 19011:2018 both permit flexibility in how audit activities are conducted, including the use of remote techniques, provided confidentiality, integrity, and effectiveness of the audit are maintained.

Stage 1 audits are primarily focused on reviewing documented information, understanding the organization’s context, confirming the ISMS scope, and assessing readiness for stage 2. Reviewing documents remotely is a widely accepted practice, especially when supported by appropriate confidentiality agreements, as was the case in this scenario. The auditors had already signed confidentiality agreements, mitigating the risk of information disclosure.

Option B is incorrect because remote document review does not inherently lead to a breach of confidentiality. Risks must be managed, not assumed. Secure document-sharing platforms and confidentiality agreements are sufficient safeguards when properly implemented. Option C is incorrect because the use of different locations or remote methods does not automatically reduce audit efficiency; in many cases, it enhances efficiency by reducing travel time and allowing better preparation.

Therefore, allowing remote review of documented information during stage 1 is fully consistent with ISO auditing standards and recognized certification body practices.

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. : 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:
