Problem Statement
How do you build a forensic timeline after an intrusion and what sources do you prefer?
Explanation
Start with a clear time anchor, like the first alert. Pull endpoint logs, EDR telemetry, Windows Event Logs, Sysmon, Linux audit logs, web server logs, DNS, VPN, and proxy records. Normalize timestamps to one zone. Sequence key events: initial access, privilege change, lateral movement, data staging, exfil. Fill gaps with file system metadata and registry or config changes. A solid timeline reveals scope, helps with containment, and validates eradication.
