What is an important step for an incident responder to take after completing an incident impact assessment?

After completing an incident impact assessment, writing a detailed incident report is a crucial step for an incident responder. This report serves several key purposes. It documents what happened during the incident, the analysis of its impact on the organization, and the effectiveness of the response. A detailed report ensures that there is a formal record of the incident which can be referenced later for analysis, lessons learned, and accountability.

Additionally, an incident report is essential for compliance purposes; many organizations are required to keep a formal record of security incidents by regulations or frameworks they adhere to. It also aids in the identification of trends and patterns that may emerge from multiple incidents over time. This documentation can be invaluable for future incident response efforts and helps in refining security measures and response strategies.

By contrast, revising policies, conducting training sessions, and initiating a security audit, while important actions to take for improving overall security posture, generally follow the documentation of the incident. They are part of the continuous improvement process informed by the findings in the incident report.
