The availability of high quality documentation of the IS as well as knowledgeable stakeholders are an important prerequisite for successful IS security risk management processes. However, little is known about the relationship between stakeholders, their knowledge about the IS, security documentation and how quality aspects influence the security and risk properties of the IS under investigation. We developed a structured data quality assessment process to identify quality issues in the security documentation of an information system. For this, organizational stakeholders were interviewed about the IS under investigation and models were created from their description in the context of an ongoing security risk management process process. Then, the research model was evaluated in a case study. We found that contradictions between the models created from stakeholder interviews and those created from documentation were a good indicator for potential security risks. The findings indicate that the proposed data quality assessment process provides valuable inputs for the ongoing security and risk management process. While current research considers users as the most important resource in security and risk management processes, little is known about the hidden value of various entities of documentation available at the organizational level. This study highlights the importance of utilizing existing IS security documentation in the security and risk management process and provides risk managers with a toolset for the prioritization of security documentation driven improvement activities.
