Forensic Image
Forensic Image: A bit-for-bit copy of a storage medium for forensic analysis. This concept is relevant to forensic investigations and reconstruction. Data must be secured in a traceable manner, preserved unchanged, professionally analyzed, and fully documented.
How it works and where it fits
Forensic Image 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.
