An intrinsic vulnerability refers to a weakness that is inherent to a system or tool, such as a data processing tool's inability to perform bound checking on arrays. This characteristic makes the system susceptible to issues like buffer overflows, which can lead to crashes or other types of failures. References: = The concept of intrinsic vulnerability is based on the understanding that certain vulnerabilities are built into the system and are not influenced by external factors. This aligns with the general principles of information security management systems and the content typically covered in ISMS ISO/IEC 27001 Lead Auditor training and certification programs

The two true statements are B and E. According to ISO 19011:2022, the audit plan describes the arrangements for a set of one or more audits planned for a specific time frame and directed towards a specific purpose1, while the audit programme describes the activities and arrangements for an audit2. The other options are either false or irrelevant. The responsibility for managing the audit programme rests with the audit programme manager, not the audit team leader (A)3. The audit plan can be changed during the conducting of the audit if necessary, with the agreement of the audit client and the auditee 4. The audit programme and the audit plan are not the same thing, so D and F are incorrect.

Explanation:
One possible way to complete the sentence is:
"When reviewing the effectiveness of action taken in response to a nonconformity, an auditor seeks evidence of change that will prevent recurrence of the issue." According to ISO/IEC 27001:2022, clause 10.1, the organization shall continually improve the suitability, adequacy, and effectiveness of the ISMS by evaluating the performance and the effectiveness of the ISMS, ensuring that the policy and objectives are aligned with the strategic direction of the organization, and taking actions to achieve the intended outcomes of the ISMS. One of the ways to achieve continual improvement is to identify and correct nonconformities and take actions to eliminate their causes and prevent their recurrence.
Therefore, when reviewing the effectiveness of the corrective actions, an auditor should look for evidence that the organization has analyzed the root cause of the nonconformity, implemented appropriate changes to the ISMS, and verified that the changes have resulted in the desired improvement and prevented the recurrence of the issue.

The use of new technologies such as big data presents new challenges in auditing, particularly the issue of combining structured and unstructured data. Big data environments often include diverse data sets that auditors need to understand and interpret, which requires new skills and approaches to ensure effective and comprehensive audit coverage.
