Forensics: reconstruct what really happened
Digital forensic investigation reconstructs, after an incident, the precise timeline of an attack from the traces left on systems: logs, modified files, network connections, and live memory at the time of the events.
Definition
This discipline answers specific questions: how the attacker got in, which systems were affected, what data may have been accessed or exfiltrated, and whether access has been closed off. These answers determine both technical remediation and legal obligations, including notification in the event of a personal data breach.
Methodological rigor matters as much as technical expertise: preserving the integrity of collected evidence is essential if the incident is to be the subject of a complaint or legal proceedings. This is why a forensic investigation follows documented procedures from end to end.
Key points
Reconstruct the timeline
The investigation precisely traces the sequence of an attack, from initial entry through to detection.
Legal stakes
The findings may determine whether notification to the CNIL is required or support legal proceedings.
A rigorous methodology
Preserving the integrity of collected evidence is an end-to-end requirement of the investigation.
How BCIT can support you
Digital forensic investigation is part of our incident response and cyber crisis management.
Frequently asked questions ❓
Is a forensic investigation always necessary after an incident?
It is recommended whenever there is doubt about the extent of the compromise, especially if a notification RGPD may be required.
Who can conduct a forensic investigation?
A specialized team, internal or external, following a rigorous methodology that preserves the integrity of collected evidence.
