In this increasingly digital world, computers and mobile phones allow us to complete a range of processes wherever we are in the world, such as checking our bank balance, uploading photographs and chatting with our friends. Unfortunately, there are some individuals who illegally take advantage of this technology, using it to aid them in a variety of criminal activities. In criminal cases, it is vital that a computer forensic professional analyses digital data found on these devices, to help the police to maintain the chain of evidence between the device and those involved to the crime.
Computer forensics is a much wider conception and theory which investigates the transgressions upon computers by virus or cybercriminals. Several acts have been brought into force in order to monitor the criminal activities, yet there are a lot more that still exist. It is very difficult to uncover such activities due to lack of enough proof or substantiation. All these complex situations can be controlled with the assistance of computer forensics. They search for and through both existing and previously existing, or deleted data. Forensic software can help in the data recovery process. They can retrieve data in relation to a crime, and obviously, the culprit does not want the data to be found.
The key dictum of computer forensic specialists is to not simply find the illicit but to also find the facts and evidence. The arrangement of the substantiation is done in a manner that leads the criminal to face legal action.
The need for computer forensics expert becomes all the more important when one considers the fact that the only data that matters is in electronic form. Along with some useful information he can uncover gigabytes of other information that has no relevance on the case. It is for him to resurrect and reconstruct data and extract only the meaningful part, all done using a method that does not tamper or alter the original data in the system in any way. This calls for specialized techniques, use of a well-equipped lab and knowledge.
Knowledge of extraction of meaningful data is, of course, a prime consideration but what is more important is that the computer forensic professional also has full knowledge of the law and be able to extract and present evidence in a way that is acceptable in court. Cybercrime today is not limited to one geographic location. Computer Forensics makes it easy for the controlled, structured and cautious detection of offense and misuse cases. The computer forensics specialists possess adequate knowledge of data retrieval software as well as hardware technicalities and should have the skill and experience to execute the job.
Computer forensics specialists conduct a structured investigation, documenting evidence that enables the court to determine what has happened to the IT system – and who is responsible for it. They investigate the identity or identification of the offender, the period and extent of the crime, and information on the motivation and execution of the crime. They can recover all types of data.
