Data Forensics
Forensics is an ever evolving science with a lot of possibilities get deeper knowledge about by different forensics training or forensics classes.
The number of crimes involving electronic data is sky-rocketing these days, particularly with the immense preponderance of computers and other digital media in our lives. 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 sexual harassment, intellectual property theft, discrimination, breach of contract and so on. Therefore, it is not that difficult to understand why data forensics is so important in the legal system.
A normal type of computer investigation cannot detect or extract bits of information remained after deletion. File left-overs, deleted files, hidden and discarded files are searched and analyzed as part of the data forensics analysis. Although it often seems impossible to identify the criminal process or to recover data, this search for the needle in the haystack is pretty successful. What is the relevance of such evidence 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.
The challenges that data forensics expert have to face are enormous. The applications are indeed far-reaching, but it takes hours to extract digital evidence and make it stable. 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. Lots of skills, strict standards and great caution are needed for each of these steps and only real pros can succeed.
When a criminal act involving digital systems is detected, the best way of action is not to address the other party and ask for a preservation of computer records, but rather a surgical approach by an expert in data forensics. This will enable the appropriate and cost-limited data collection in the best conditions possible. 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. Even photocopy machines include hard drives and the scanned or copied documents can be afterwards retrieved from them.
