As you might have already heard, computer forensics have become the new heroes of the information age helping to catch evil-doers by digging for mysterious files hidden deep within their computer hard drives...
But what exactly is computer forensics?
One site gives the definition as, "...the use of analytical and investigative techniques to identify, collect, examine and
preserve evidence/information which is magnetically stored or encoded."
In simple terms, it means looking at the data on a hard drive or other computer storage device, (especially files that have been
deleted), and figuring out what the person who was using that computer was trying to do with it.
It's not as easy as it sounds. In order for data to be admissible in court you need to know and follow the strict computer forensics guidelines that experts in digital forensics have developed.
With the proper tools and software, forensics
experts can retrieve deleted files, Web pages
visited, or a complete record of emails
as evidence in criminal trials.
Private cyber forensics consulting firms work with law enforcement as well as large and small companies. These cyber investigators
can help track terrorists, stop traffic in child pornography, or discover the culprit who infects emails or web sites with
malicious viruses, and help police solve other criminal investigations.
In the hands of a trained forensics expert, a computer can provide proof of fraud or harassment long after digital evidence was thought
to have been deleted.
In the age of increased computer security, "detectives" in this field can also snag people in white collar crimes, such as industrial espionage which
can be a big problem if a corporation is about to launch a new product or marketing campaign.
In fact, a few large companies
have even hired full-time computer forensics experts to fend off any possibility of digital theft or tampering.
