Computer forensic professionals are as important today as programmers, repair experts and operators because they:

Track down the bad guys – As useful as computers have proven in today’s society, they are also the perfect tools of crime when placed in the right hands. The bad guys have figured out how to use these machines for everything from stealing money to stalking children. Forensic computer experts work to catch these guys by discovering how they commit crimes, where they commit crimes from and ultimately who they are. Many law enforcement agencies, including the FBI, have created cyber crimes divisions to fight back against high-tech criminals.

Prevent bad guys from getting in – Private practice computer forensic experts not only assist with criminal and civil cases, but they also help prevent them from happening in the first place. They do this by assisting individuals and companies in making sure their networks are secured.

Educate people about security and protocols – Some computer forensic experts are willing to play host to seminars and workshops that not only explain their field, but also illustrate what people should be doing to protect themselves.

When a computer crashes or otherwise is rendered unusable, many people just dispose of the old machine in the trash. For businesses and individuals who have personal information stored on their old machines, this can turn out to be a nightmare. Even if the information isn’t accessible by the owner, it can be by a bad guy. This is where computer forensic expertise can come in handy to protect valuable data prior to disposal.

While not all computer forensic experts offer services designed to protect old hard drives from information thieves, some do. When this is the case, a computer forensic expert will:

Completely wipe a hard drive clean – The purpose of hard drive cleaning services prior to disposal is to make sure that traces of data, such as credit card numbers and banking information, cannot be accessed by anyone. Computer forensic experts often offer this service along with a host of others designed to protect people, businesses and their personal information.

Certify the work – When a computer forensics expert does offer hard drive cleaning service, chances are certification of the work will go along with the job. This is important especially for companies that need the peace of mind a written guarantee provides.

If a computer is functional, but is being replaced with an upgrade, computer forensic experts can still provide some security. A hard drive wipe won’t render a hard drive useless. This means old computers can be passed on to others or donated to charity without concern that sensitive information will fall into the wrong hands.

Throwing away a computer or passing it along without having the hard drive properly cleaned can prove to be a very bad idea. The truth is that even damaged hard drives can be accessed by skilled information thieves and personal data can be compromised. When computer forensic experts handle a data wipe, however, the worries can melt away.

When there is a need to hire a computer forensic pro to tackle a job some people wonder why they must pay out the expense. After all, a regular “computer guy” would be able to find missing files, repair damaged data or trace usage, right?

Possibly.

But, can an average computer guy unravel mysteries to make found evidence presentable and intelligible in court?

Probably not!

The truth about computer forensics experts is that they are very different from typical computer repair people. While there are portions of the two professions that do intermingle, there are some distinct features that make computer forensic experts stand out. They include:

It can be terribly frustrating to know that a computer might contain information that would either prove or disprove a criminal or civil case. When finding that information is a must, but protecting its integrity is, as well, forensic computer professionals can deliver on the job. As long as evidence is in fact contained on a machine, these experts are uniquely qualified to bring peace of mind and even closure to a case.

Forensic computer professionals are not like other experts in the computer field. Rather than repair, program or build machines, they specialize in finding traces of information that might be left on a hard drive that could serve as evidence in civil and criminal cases.

Computer forensic experts get the job done by:

Examining a machine – Before a full-scale investigation is launched to study a hard drive and its contents, forensic computer pros do a cursory search to determine if evidence is likely to be found. This can either lead to an escalation in the investigation or a decision that a particular machine might not yield the necessary information.

Cloning of a hard drive – It is very important to protect information stored on a computer for presentation in court. To make sure original data isn’t lost or damaged during a search, investigators will commonly clone the original hard drive.

Careful examination of the clone – Once a clone is made, forensic computer pros will go to work seeking out evidence. This might include a file search, restoring deleted files and even repairing damaged ones. It can also involve Internet use studies and even decoding encrypted files.

Presentation in court – If information is found that is valuable for a case, skilled forensic computer investigators will often present the evidence in court themselves. If not, they are often willing to stand by to explain their procedures and how evidence was located.

If there is evidence to be found, chances are a forensic computer investigator will be able to spot it. In the process, these skilled professionals bring peace of mind to their clients.

There is more to computer forensic investigations than turning on a machine and seeking out files. If this were the case, anyone with the wherewithal to run a basic search could claim to be a forensic computer pro. But, since a lot of bad guys happen to not only be high-tech, but also savvy as well, a special brand of expertise is required for this field.

When the bad guys in criminal or civil cases do happen to be savvy, it takes training, skill and deductive reasoning to puzzle out a case. The fact is that “smart” criminals don’t want to leave traces behind that might implicate them. That means some encrypt their files with serious protections. Others might write in codes or use pictures to send messages. This is where talent for computer forensic investigations can often save the day or prove the case.

To make certain a computer forensic expert with the right knowledge and skill for the task is hired for a job, look for:

Experience – Computer forensics is not a field that one learns overnight. To be able to figure out clues left behind, pros in computer forensic investigations often need years of experience.

Training – The best training in forensic computer investigations often comes from the law enforcement field. When a skilled investigator is needed, look for those who have either worked in law enforcement or who have obtained identical training.

Certification – There are governing agencies that oversee computer forensic investigators. Often, the most highly skilled professionals carry credentials from these agencies.

Networking ability – Just as someone might require a little help to finish a complex crossword puzzle, forensic computer investigators often call on each other to figure out complicated cases to reveal hidden evidence. The best investigators will have a large networking base to assist them with their own cases. This reciprocal type of situation can benefit clients greatly.

There is more to computer forensic investigations than simple file searches. When the evidence isn’t evident, these pros can often puzzle it out.
