Tips On Computer Forensics Investigation

By Peter Gray


In an exceedingly paperless world, computers have been become so accessible that almost every home can afford to have one for personal use. This accessibility combined with the increasing computer education has led to a population that has the digital world at their fingertips making communication and work much easier than it used to be. On the downside of this however crime and its ability to be committed and concealed with nothing more than simple computer has also advanced. Computer forensics investigation is vital in this time and era.

Today, technology has increasingly become extremely integrated especially into individual lives, so much so that they expect to always have a very constant access to their individual mails, and also keep in constant touch with their social circle even during the working hours. This therefore means that organizations may be very susceptible to things like cyber-crime and other online-related frauds. Oftentimes, the organizations are usually much unprepared in dealing with such circumstances efficiently.

The examination usually follows a detailed and comprehensive process to ensure that all facts are put out well and the evidence provided is effective. The phases are inclusive of acquisition, examination, analysis and finally reporting. The tools that are available for a criminologist have set higher standards thus providing factual and precise evidence that the courts can rely on to make a ruling.

There are a number of methods used during the investigation and they are mostly applied by the law enforcement for example a criminologist. Cross drive analysis is an example of a technique used whereby the facts found on numerous hard drives is correlated and thus can be used to classify shared networks and hence implement irregularity detection. In cases where encryption of data is required the live analysis technique is used, the encryption keys are unruffled using tools to extract evidence.

The actual acquisition of the evidence is then carried out but as earlier stated must follow all legal channels to preserve its integrity and ensure it is admissible in a court of law. Sensitive material must be transferred via controlled disks and appropriately copied to the investigators storage system, follow the required chain of custody and transported in a manner that protects it from loss, damage or compromise. This then paves the way for evidence analysis.

Therefore, in order to properly handle these cyber-related crimes, services of competent computer forensic experts become extremely important. These experts usually possess exemplary skills in handling these issues, since they have amassed great knowledge requisite in dealing with these cyber-related issues. The skills they have generally involve not only the preservation but also accurate identification of digital proof or evidence.

When faced with these cases that require forensic investigations, companies usually tend to concentrate solely on the high costs involved, and overlook the actual situation or ramifications that will result if proper mechanisms are not employed. Evidence that is acquired after the examinations of a competent computer forensics expert can prove to be very weighty and handy, and thus inform the successful results of the investigations. In addition, these services will also reduce the essence of a complete legal tussle or action.

Once all the necessary data or evidence has been obtained a detailed report of all procedures, policies methods and tools used in the entire process must be well documented. These reports are especially vital in court cases because they are a way for any one who wishes to challenge the evidence to see a clear sequence of events that helps confirm that the evidence is authentic and credible which could ultimately directly affect the outcome of a court case.
