In the context of a third-party certification audit, it is very important to have effective communication between the audit team and the auditee. The formal communication channels, such as the names and contact details of the audit team members, the auditee representatives, the audit client and any other relevant parties, can be established during the opening meeting. This helps to ensure that the audit objectives, scope, criteria, methods, schedule and any other arrangements are clearly understood and agreed by all parties. It also facilitates the exchange of information, feedback, requests, concerns and complaints during the audit process.

Explanation:
"An audit finding is the result of the evaluation of the collected audit evidence against audit criteria." The words that best complete the sentence to describe an audit finding are evaluation and evidence. According to ISO 19011:2022, an audit finding is the result of the evaluation of the collected audit evidence against audit criteria12. The other options are either not related to the definition of an audit finding or do not fit the sentence grammatically.

Conducting an ISO/IEC 27001 audit

This is a minor nonconformity. The backup frequency not adhering to the company's procedure of daily backups but occurring once a month represents a deviation from established processes, yet it might not immediately impact the effectiveness of the information security management system.

Confidentiality is one of the principles of audit conduct that auditors should adhere to when performing audits. Confidentiality means that auditors should exercise discretion in the use and protection of information acquired in the course of their duties3. Auditors should respect the intellectual property rights of the auditee and other parties involved in the audit, and should not disclose any information that is sensitive, proprietary, or confidential without prior approval from the auditee or other authorized parties3. Auditors should also obtain the auditee's permission before using a camera or recording equipment during an audit, as these devices may capture confidential information or infringe on the privacy of individuals3. Therefore, these two options correctly state the function of confidentiality in an audit. The other options are either incorrect or irrelevant to confidentiality. For example, auditors are not forced by regulatory requirements to maintain confidentiality in an audit, but rather by ethical obligations and contractual agreements3. Observers in an audit team can access confidential information if they have signed a confidentiality agreement and have been authorized by the auditee3. Audit information can be used for improving personal competence by the auditor only if it does not compromise confidentiality or conflict with other interests3. As an auditor is always accompanied by a guide, there is still a risk to the auditee's sensitive information if the guide is not trustworthy or authorized to access such information3.

ISO/IEC 27001 does not mandate the use of a specific risk assessment methodology. Organizations are free to choose their own approach as long as it is systematic, consistent, and capable of producing valid and comparable results. This allows organizations, such as the marketing agency in the question, to adapt the methodology to suit their specific needs and business context, provided it complies with the requirements set out in the standard.
