PECB Updated ISO-IEC-27001-Lead-Auditor Exam Questions and Answers by fatimah

According to ISO 19011:2018, which provides guidelines for auditing management systems, an auditor conducting a certification audit should prepare for an audit by reviewing relevant information about the auditee’s context and processes1. This may include reviewing documented information related to the audited management system (such as policies, procedures, manuals), previous audit reports and records (such as findings, nonconformities, corrective actions), relevant legal and regulatory requirements (such as laws, standards), relevant risks and opportunities (such as internal and external issues), relevant performance indicators (such as objectives, targets), etc1. Therefore, an auditor may need work documents such as an audit plan (which defines what will be done during an audit), a sample plan (which defines how many samples will be taken from a population), and a checklist (which helps to ensure that all relevant aspects are covered during an audit)1. However, an auditor does not need work documents such as an organisation’s financial statement (which is not directly related to information security management), a career history of the IT manager (which is not relevant to assessing conformity with ISO/IEC 27001:2022), or a list of external providers (which is not necessary for planning an audit)1. References: ISO 19011:2018 - Guidelines for auditing management systems

Comprehensive and Detailed In-Depth Explanation:

A preventive control is a security measure implemented to prevent security incidents or risks from occurring. It proactively protects information systems and mitigates potential threats.

A. Using an application that prioritized orders based on its prior knowledge – This is an operational enhancement but not a security control. It improves efficiency but does not directly prevent security breaches or risks.

B. Signing a confidentiality agreement – This is a preventive control because it ensures that sensitive business information remains protected from unauthorized disclosure before transitioning to an outsourced service provider. It mitigates the risk of intellectual property theft or data misuse by legally binding the parties to confidentiality.

C. Expanding the capacity of the in-house data center – This is a corrective or operational control, as it addresses the issue of insufficient infrastructure but does not prevent security-related threats.

This aligns with ISO/IEC 27001:2022 Annex A Control A.5.6 (Contact with Special Interest Groups), which includes legal agreements and confidentiality measures to protect sensitive information.

According to ISO/IEC 17021-1, which specifies the requirements for bodies providing audit and certification of management systems, a certification body should establish criteria for determining audit time and audit team composition based on factors such as the scope of certification, size and complexity of the organization, risks associated with its activities, etc2. Therefore, if an auditee requests to extend the audit scope to include two additional sites after completing Stage 1 of an initial certification audit, the audit team leader should obtain information about the additional sites to inform the certification body, so that they can review and approve the change in scope and adjust the audit time and audit team accordingly2. The other options are not appropriate actions for the audit team leader to take in this situation. For example, increasing the length of the Stage 2 audit to include the extra sites without informing the certification body may violate their procedures and policies; arranging to complete a remote Stage 1 audit of the two sites using a video conferencing platform may not be feasible or effective depending on the nature and location of the sites; and informing the auditee that the request can be accepted but a full Stage 1 audit must be repeated may not be necessary or reasonable if there are no significant changes in the auditee’s ISMS since Stage 12. References: ISO/IEC 17021-1:2015 - Conformity assessment – Requirements for bodies providing audit and certification of management systems – Part 1: Requirements

The only option that is not prohibited in acceptable use of information assets is C: company-wide e-mails with supervisor/TL permission. This option implies that the sender has obtained the necessary authorization from their supervisor or team leader to send an e-mail to all employees in the organization. This could be done for legitimate business purposes, such as announcing important news, events or updates that are relevant to everyone. However, this option should still be used sparingly and responsibly, as it could cause unnecessary disruption or annoyance to the recipients if abused or misused. The other options are prohibited in acceptable use of information assets, as they could violate the information security policies and procedures of the organization, as well as waste resources and bandwidth. Electronic chain letters (A) are messages that urge recipients to forward them to multiple other people, often with false or misleading claims or promises. They are considered spam and could contain malicious links or attachments that could compromise information security. E-mail copies to non-essential readers (B) are messages that are sent to recipients who do not need to receive them or have no interest in them. They are considered unnecessary and could clutter the inbox and distract the recipients from more important messages. Messages with very large attachments or to a large number of recipients (D) are messages that consume a lot of network resources and could affect the performance or availability of the information systems. They could also exceed the storage capacity or quota limits of the recipients’ mailboxes and cause problems for them. ISO/IEC 27001:2022 requires the organization to implement rules for acceptable use of assets (see clause A.8.1.3). 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 Acceptable Use?
