Given a Scenario, use Data, Artifacts and Sources to Support a Security Investigation
When investigating a security incident, the quality of the evidence is just as important as the investigation itself. Security professionals must know where to obtain reliable information, how to preserve digital evidence, and which people and technologies can assist throughout the investigation. In this chapter, you will learn how logs, forensic artifacts, data sources, system images, stakeholders, and log-parsing techniques are used to identify attacks, reconstruct events, and support informed security decisions.
