Introduction to Logs
Attackers often try to hide traces of their actions. However, security teams can piece together clues to understand how an attack occurred and sometimes even identify the attacker.
Imagine a crime scene where a locket is stolen from a snowy jungle cabin. Police notice signs like damaged doors, collapsed ceilings, footprints in the snow, and even nearby CCTV footage. By combining these clues, they determine the culprit.
Digital incidents leave similar traces within systems, and these traces are primarily found in logs. Logs are records of activities on a system, whether normal or malicious. They act as digital footprints, helping investigators trace events back to their origin.
