Which of the following phases of an incident response involves generating reports?

The "Lessons learned" phase of incident response is where the incident is reviewed, documented, and analyzed to identify what went well, what could be improved, and to generate reports that inform future incident response efforts. This includes creating a final report detailing the incident, the response, and recommendations. "Recovery" focuses on restoring systems and services to normal operation. "Preparation" involves activities before an incident occurs, such as developing policies and training. "Containment" aims to limit the scope and impact of an ongoing incident. While documentation occurs throughout the process, the formal reporting and analysis for improvement are central to the "Lessons learned" phase.
