Data Forensics

Forensics is an ever evolving science with a lot of possibilities acquire deeper knowledge about by different forensics schools or forensics colleges.
With the ever increasing importance of computers and digital media for both personal and corporate users, the number of crimes involving electronic data is now higher than ever. Thus, data forensics has become a distinct sub-division of forensic science consisting of technical expertise, the finding of electronic evidence, digital investigations and even data recovery. To count only a few of the judicial cases for which data forensics is useful, we ought to mention breach of contract, intellectual property theft, discrimination, sexual harassment and so on. Therefore, it was not difficult for data forensics to become a legal necessity in the context of the computers’ ubiquity.

The exact specificity of data forensics is the extraction of pieces of information that would remain undetected at a normal investigation. File left-overs, deleted files, hidden and discarded files are searched and analyzed as part of the data forensics analysis. Although there are lots of challenges when trying to recover data or to identify the criminal process, experts in this fields have more than once been successful at finding the needle in the haystack. What relevance does such evidence have for legal cases? Well, it has been proved by practice that the recovery of a deleted e-mail message can change the course of a trial.

Data forensics constantly needs to face apparently unsurmountable challenges. The applications are indeed far-reaching, but the work to extract digital evidence is strict and exhausting. Sometimes the extractor has difficulties in getting to the information that is buried too deep in the electronic system, or too exposed to destruction. This is also the reason why a duplication procedure is used to protect the information during the extraction process. Great caution, strict standards and lots of skills are required for each of these steps and only real pros can succeed.

A data forensics expert should be contacted immediately, once a breach in the security system or a criminal act against electronic media is detected. This will reduce the costs of data collection and will make info recovery more likely. Besides computers, there are other electronic storage devices that can be the target of criminal activity, and data forensics also deal with hacked USB devices, DVDs or voice mail systems. Memory hard drives are now incorporated even in fax and photocopy machines so that many of the documents can be recovered afterwards.
