Rapports d'investigations

Digital investigation involves identifying, collecting, analyzing, documenting, and presenting digital evidence. Identification begins by detecting security incidents and identifying potential evidence sources like system logs and user reports. Preservation ensures data integrity through disk imaging and write blockers, maintaining a chain of custody. Analysis involves examining collected data, including log files, malware, and network traffic, to extract relevant information. Documentation is crucial, with timestamping, screenshots, and structured reports. Presentation involves communicating findings through technical reports, visual summaries, and court testimony. Understanding how protections are bypassed is also essential, analyzing evasion techniques. Recovering deleted files and connection histories helps uncover traces. Finally, detecting hidden evidence requires steganography and analysis of unallocated space. This structured approach is critical for legal validity and reproducibility in any digital investigation. Each stage must be conducted with rigor and meticulous record-keeping. The goal is to understand events, identify actors, and reconstruct activities.
