This scenario aligns closely with CHFI v11 objectives under Procedures and Methodology, specifically postmortem analysis and log-based forensic investigation. Postmortem analysis refers to the examination of collected system, application, and network logs after an incident has occurred, with the goal of reconstructing events and determining the root cause of a security breach.
In this case, the investigator is reviewing historical network logs collected during the incident window, not monitoring live traffic. CHFI v11 emphasizes that postmortem analysis is essential for answering the core forensic questions: what happened, how it happened, when it happened, and who was responsible. By correlating timestamps, IP addresses, protocols, and event sequences across logs, investigators can identify attack vectors, trace the origin of the attack, and understand attacker behavior.
