What is the purpose of diagraming a timeline of activities during incident analysis?

The purpose of diagramming a timeline of activities during incident analysis is primarily to track event correlations. This tool aids in visually representing the sequence of events that occurred before, during, and after an incident, allowing analysts to pinpoint how different events may have interacted with each other. By placing activities on a timeline, patterns, relationships, and trends can be observed more easily, which is crucial in understanding the root causes of incidents and how they unfolded.

Tracking event correlations in this manner is essential for building a comprehensive view of what happened and for determining the effectiveness of response actions. This understanding can lead to informed decisions on how to enhance incident management processes, prevent future incidents, and improve overall security posture.
