In which stage of forensics does a forensic expert interpret data and examine file structures for tampering signs?

The stage of forensics where a forensic expert interprets data and examines file structures for signs of tampering is the analysis stage. During this phase, the expert delves deeply into the collected data to identify patterns, anomalies, and any indications of manipulation or unauthorized access. This involves using various tools and methodologies to scrutinize file systems, examine logs, and assess the integrity of data.

In this context, analysis is crucial because it translates raw data into meaningful insights, allowing forensic experts to draw conclusions about the events that transpired. This may involve recovering deleted files, analyzing metadata, and understanding the context surrounding the data.

The other stages serve different purposes: identification focuses on recognizing potential sources of evidence, collection emphasizes gathering relevant data in a forensically sound manner, and presentation involves summarizing findings for stakeholders or in court settings. Each stage is essential to the forensic process, but the act of interpreting and examining data in detail is specifically part of the analysis stage.
