Digital Forensics
Also known as:DFIR
Digital Forensics: Preserves and analyzes digital traces to reconstruct security-relevant events. The term is relevant to investigations and reconstructions that meet evidentiary standards. Data must be backed up in a traceable manner, preserved unaltered, analyzed professionally, and fully documented.
For Windows investigations, the Eric Zimmerman ToolsEric Zimmerman ToolsTool suite for forensic analysis of Windows artifacts such as Registry hives, event logs, the MFT, LNK files, and Jump Lists. support structured analysis of many persistent artifacts.
How it works and where it fits
Digital Forensics belongs to a prepared workflow for handling security-relevant events. A technical signal becomes a substantiated incident only through triage, context, and assessment. Roles, decision authority, escalation paths, and stopping conditions should therefore be agreed in advance so actions remain consistent under time pressure.
Practical security relevance
Execution must balance rapid containment with careful evidence preservation. Actions should not unnecessarily destroy important traces or disrupt business operations without control. Timelines, decisions, and changes are documented; after recovery, root causes, identified gaps, and lessons learned feed back into controls, detection logic, and response plans.
