The audit objectives are the purpose and scope of an audit, as defined by the audit client and the auditor. According to the ISO/IEC 27001 standard, the audit objectives for an ISMS audit may include determining the extent of conformity of the ISMS with the audit criteria, evaluating the ability of the ISMS to ensure the organization meets its information security objectives, and identifying potential areas for improvement of the ISMS12. Reference: = 1: PECB Candidate Handbook - ISO/IEC 27001 Lead Auditor, page 192: ISO/IEC 27007:2011 Information technology - Security techniques - Guidelines for information security management systems auditing, clause 4.2.1.
Comprehensive and Detailed In-Depth C . Correct Answer: The audit team documented findings, but the scenario does not confirm whether sufficient supporting evidence was included. ISO 19011:2018 requires audit findings to be properly documented and justified with evidence. Failing to document evidence reduces audit credibility. A . Incorrect: Preparing for the audit by reviewing policies and procedures is correct practice. B . Incorrect: Evaluating management responsibility for ISMS compliance is a required step in Stage 1.

Question 203
情境 5：Data Grid Inc. 是一家知名公司，為整個資訊科技基礎設施提供安全服務。它提供網路安全軟體，包括端點安全、防火牆和防毒軟體。二十年來，Data Grid Inc. 透過先進的產品和服務幫助多家公司保護其網路安全。 Data Grid Inc. 在資訊和網路安全領域享有盛譽，決定獲得 ISO/IEC 27001 認證，以更好地保護其內部和客戶資產並獲得競爭優勢。 Data Grid Inc. 任命了審計團隊，該團隊同意審計任務的條款。此外，Data Grid Inc.明確了審核範圍，明確了審核標準，並建議在五天內結束審核。由於Data Grid Inc.員工人數眾多，流程複雜，審計小組拒絕了Data Grid Inc.在五天內進行審計的提議。 Data Grid Inc.堅稱他們計劃在五天內完成審核，因此雙方同意在規定的時間內進行審核。審計小組遵循基於風險的審計方法。 為了獲得主要業務流程和控制的概述，審計團隊存取了流程描述和組織圖表。他們無法對 IT 風險和控制進行更深入的分析，因為他們對 IT 基礎架構和應用程式的存取受到限制。然而，審計小組表示，Data Grid Inc. 的 ISMS 出現重大缺陷的風險很低，因為該公司的大部分流程都是自動化的。因此，他們透過詢問 Data Grid Inc. 的代表以下問題來評估 ISMS 整體上符合標準要求： *如何定義和指派 IT 和 IT 控制的職責？ *Data Grid Inc. 如何評估控制措施是否達到了預期效果？ *Data Grid Inc. 採取了哪些控制措施來保護操作環境和資料免受惡意軟體的侵害？ *是否實施了與防火牆相關的控制？ Data Grid Inc. 的代表提供了充分且適當的證據來解決所有這些問題。 審計組長起草審計結論並向Data Grid Inc. 的最高管理階層報告。 儘管審核員推薦Data Grid Inc.進行認證，但Data Grid Inc.與認證機構之間在審核目標方面產生了誤解。 Data Grid Inc. 表示，儘管審計目標包括確定潛在改進的領域，但審計團隊並未提供此類資訊。 根據該場景，回答以下問題： 根據情境 5，審核團隊不同意 Data Grid Inc. 針對 ISMS 審核提出的審核持續時間。您如何描述這樣的情況？
Correct Answer: A
Auditors have the authority to object or even refuse an audit mandate if they believe that the audit duration proposed by the auditee is not sufficient to thoroughly assess the ISMS. It is crucial for the audit to be comprehensive enough to cover all necessary aspects of the system, ensuring its effectiveness and compliance.

A document review is a process of examining the documented information related to the management system before the on-site audit activities. The purpose of a document review is to: 12 * Determine the conformity of the management system, as far as documented, with audit criteria, i.e., to check whether the documents are consistent, complete, and compliant with the requirements of ISO /IEC 27001 and any other applicable standards or regulations. * Gather information to support the on-site audit activities, i.e., to identify the scope, objectives, processes, controls, risks, and opportunities of the management system, and to plan the audit methods, techniques, and resources accordingly. The other statements are not accurate, because: * A document review does not reveal or decide about the conformity or nonconformity of the management system as a whole, but only of the documented information. The conformity or nonconformity of the management system is determined by the on-site audit activities, which include interviews, observations, and tests12 * A document review does not gather evidence or findings to support the audit report or process, but information to support the on-site audit activities. The evidence or findings are collected during the on- site audit activities, which are then documented and reported12 * A document review does not detect any nonconformity of the management system, if documented, but determines the conformity of the documented information. The nonconformity of the management system is detected by the on-site audit activities, which evaluate the performance and effectiveness of the management system12 * A document review does not identify information to support the audit plan, but gathers information to support the on-site audit activities. The audit plan is prepared before the document review, based on the audit scope, objectives, criteria, and program. The document review is part of the audit plan implementation12 References: 1: ISO/IEC 27001:2022 Lead Auditor (Information Security Management Systems) Course by CQI and IRCA Certified Training 1 2: ISO/IEC 27001 Lead Auditor Training Course by PECB 2
According to ISO/IEC 27001:2022 clause 8.1, the organization must plan, implement and control the processes needed to meet the information security requirements, and to implement the actions determined in clause 6.1. The organization must also ensure that the outsourced processes are controlled or influenced. According to control A.5.24, the organization must establish and maintain an information security incident management process that includes reporting information security events and weaknesses. Therefore, the use of lower grade machines for the secure disposal of confidential documents and media could pose a significant information security risk and a potential breach of contract with the clients. The auditor should respond to this information by: * A. Advising the individual managing the audit programme of any recommendation by you to conduct a further audit prior to certification. This is in accordance with ISO/IEC 27006:2022 clause 7.4.3, which states that the audit team leader shall report to the certification body any situation that may significantly affect the audit conclusions or the certification decision, and propose any necessary changes to the audit plan. * C. Considering the need for a subsequent audit within 4 weeks based on the additional information that has come to light. This is in accordance with ISO/IEC 27006:2022 clause 7.5.2, which states that the audit team leader shall review the audit findings and any other appropriate information collected during the audit to determine the audit conclusions, and to identify any need for a subsequent audit. * G. Verifying with the auditee that lower grade machines are used in certain circumstances. This is in accordance with ISO/IEC 27006:2022 clause 7.4.2, which states that the audit team leader shall ensure that the audit is conducted in accordance with the audit plan, and that any changes to the plan are agreed upon and documented. The other options are not appropriate responses, as they either ignore the information, exceed the scope of the audit, or prematurely raise a nonconformity without sufficient evidence. For example: * B. Cancelling the production of the audit report and instead reviewing the organization's contracts with its clients to determine whether they have permitted the use of lower grade machines. This is not a suitable response, as it would delay the audit process and the certification decision, and it would involve reviewing documents that are outside the scope of the ISMS audit. The auditor should focus on verifying the information security risk assessment and treatment process, and the information security incident management process, as they relate to the use of lower grade machines. * D. Doing nothing. All audits are based on a sample and the sample you took did not include a planned review of the lower grade machines. This is not a suitable response, as it would disregard a significant information security risk and a potential nonconformity that could affect the audit conclusions and the certification decision. The auditor should follow up on the information provided by the employee and verify its validity and impact. * E. Extending the certification audit duration to create additional time to audit the use of the lower grade machines. This is not a suitable response, as it would disrupt the audit schedule and the availability of the audit team and the auditee. The auditor should report the situation to the certification body and propose any necessary changes to the audit plan, such as conducting a subsequent audit. * F. Raising a nonconformity against 8.1 Operational Planning and Control as the organization has not been open about its processes. This is not a suitable response, as it would be based on a single source of information that has not been verified or corroborated. The auditor should collect sufficient and appropriate audit evidence to support any nonconformity, and should also consider the root cause and the severity of the nonconformity.
