What is Computer Forensics?

A Backup Article Contributed by Teresa Phillips

General Overview of Computer Forensics.

Computer forensics is designed to find legal evidence, bringing perpetrators to justice. Even though the evidence may have been erased, data can be recovered. Encrypted files can also be uncovered in an effort to bring the evidence to light. A computer specialists can use various methods to recover this evidence. Thereafter, that evidence can be used during discovery, depositions, or in court.

What are the Advantages of Computer Forensics?

A computer is a computer. Almost anything is essentially the same. Any version of windows can be accessed by another computer. Software types are also similar in many ways. One version of software can used to uncover evidence in other versions. Computers were designed, not for crimes, but for business, pleasure and many other sorts of work.

If they weren't designed in this way, then business "a" could not stay in contact with business "b". It would create a lot of problems for any business without that "computer network". Computers were designed to make our lives easier. Therefore, computer forensics has the advantage over any criminal that would attempt to get away with that seemingly unstoppable crime. The methodology of a forensics expert, allows for quick identification of places to look and the signs of previous of data.

Recovery of evidence is almost foolproof.

Why is the Preservation of Evidence So Critical by a Computer Forensics Expert?

The main objective of the forensics expert is to protect the chain of evidence. The crimes committed can be of the serious nature. Homicides, fraud, drug and embezzlement records keeping, and child pornography are some of the worst. Therefore, damaged or flawed evidence is basically useless in any courtroom. Evidence can be thrown out and the charges could be dropped. Dangerous criminals can be released due to insufficient evidence. Obviously, the duties of the forensics expert are very important.

Every Step Taken by the Computer Forensics Expert is Important!

First of all, the computer system must be protected. It is possible to alter or damage files. The accidental introduction of virus is also possible. All of the files and software must be examined. A detailed search is started. There are normal or existing files. Deleted and hidden files are next, always being careful to uncover them all. Password protected and encrypted files are actually the hardest to recover. They are usually the most important and contain valuable evidence. All of these steps are taken carefully and precisely. They will ensure expert testimony, as required.

The End Result of Expert Computer Forensics!

Person "a" is damaged or injured by person "b". A crime has been committed. The evidence is collected. A computer is seized by law enforcement and a forensics expert begins his most important job. The examination of the files are thoroughly gone over. Evidence is put into the hands of the prosecutor. A trial begins and expert testimony is given. The suspect is convicted and the victim is given their reprisal. Computer forensics can be rewarding if it is done properly and with a professional attitude.
