What is a forensic analysis?

Forensic analysis consists of a series of procedures that certify the evidence or findings in a reliable manner.
These include identifying evidence, acquiring data, analyzing and studying the results, and finally, preparing and presenting a report.
Data can be obtained not only from a hard drive, but also from a wide range of sources such as mobile phones, telephone routers, car control units and multimedia systems, unmanned aerial systems, or nautical devices.
All phases are important, but without a doubt, the preparation of a report that clearly, truthfully, and simply summarizes the results obtained can make the difference before a court of law.

What is the Chain of Custody?

It is a technical-legal supervision procedure used to identify and clarify digital traces related to a crime — from the moment they are detected and reported until they are evaluated by the computer forensic expert. The purpose of this procedure is to preserve the integrity of the evidence and prevent any manipulation, contamination, alteration, damage, replacement, or destruction. This procedure constitutes a formal guarantee system that aims to record all activities carried out by every person who comes into contact with the evidence.

What is the Counter-Expert Report?

The counter-expert computer forensic report is the forensic opinion issued by a computer forensic expert to identify errors in technique, methodology, structure, and chain of custody in a document submitted by the opposing party as a forensic computer report. During the preparation of this counter-expert computer report, the following aspects are verified:
  • That the computer forensic report complies with the required structure and digital forensics protocols.
  • That the chain of custody has been maintained and the evidence is repeatable.
  • That the report meets legal standards and complies with computer forensics regulations.
  • That the computer forensic expert who signs the report meets legal requirements and is qualified to issue a forensic computer report.
  • That it is a technical report and not a personal opinion presented as a forensic conclusion.
  • That the computer forensic expert has acted impartially.
