What type of information is important for Eva to gather from individual interviews?

The most relevant type of information for Eva to gather from individual interviews is a comprehensive evaluation of security policy implementation. This is crucial for understanding how well security policies are being applied in practice within the organization. During interviews, employees can provide firsthand accounts of their experiences with the security measures that have been put in place and whether these measures are effectively protecting the organization's information assets. Insight into policy implementation can help identify any gaps between policy and practice, which is vital for ensuring compliance with ISO/IEC 27001 standards.

Information about employee expertise can be valuable, but it does not directly pertain to the evaluation of security measures or how well they are functioning in terms of protecting information. Feedback on organizational culture might provide context for understanding employee behavior and attitudes toward security, yet it doesn't offer the specific insights needed to assess the effectiveness of security policies. Lastly, evaluating audit team performance assessments focuses on the auditors rather than the security policies themselves, which diverts attention from the primary goal of assessing the organization's compliance with information security standards. Thus, information regarding security policy implementation is paramount for a successful audit process in line with ISO/IEC 27001 guidelines.
