The correct option is D. There is a nonconformity (NC). The Service Manager does not comply with the software security management procedure. (Relevant to clause 8.1, control A.8.30). The IT Manager should have approved the test results according to the software security management procedure, not the Service Manager. The Service Manager's decision to accept the failed security tests also violates the "security-by- design" and "security-by-default" principles that the organization adopted. The other options are either incorrect or irrelevant. The organization and developer did perform acceptance tests, but they failed (B, C). The Service Manager's decision to continue the service does not justify the nonconformity (A).

The audit team leader suggesting a specific solution on resolving the nonconformities is unacceptable in an external audit. This could compromise the impartiality of the audit process by appearing to assist the auditee in corrective actions, which should independently originate from the auditee to ensure the integrity and effectiveness of the ISMS.

Yes, it is acceptable for Sinvestment to request that the review of documented information occur on-site. The company has the right to stipulate that no documents be carried off-site, especially to maintain control over sensitive information and ensure confidentiality, which aligns with the security controls expected in ISO/IEC
27001.

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.
