Conducting a meeting to capture lessons learned is the next step after an incident management team leader sends out a notification that the organization has successfully recovered from a cyberattack because it helps to identify the strengths and weaknesses of the current incident response plan, capture the feedback and recommendations from the incident responders and stakeholders, and implement the necessary improvements and corrective actions for future incidents. Preparing an executive summary for senior management is not the next step, but rather a subsequent step that involves reporting the incident details, impact, and resolution to the senior management. Gathering feedback on business impact is not the next step, but rather a concurrent step that involves assessing the extent and severity of the damage or disruption caused by the incident. Securing and preserving digital evidence for analysis is not the next step, but rather a previous step that involves collecting and documenting the relevant data or artifacts related to the incident.
