Info On Forensic Computer Examiner

By Peter Sanders


Forensics is a general term for the use of analyzing and investigation skills applied in criminal law. Technology today has revolutionized almost every aspect of the modern day man and tracing down suspects of crime from the calls they make or their browser information is possible through forensic computer examiner.

With the great revolution in technology in the past few years, criminals can be traced down from their devices or devices found on a crime scene. Scientific investigation generally is the application of analytical and investigative skills to extract imperative information from computing gadgets in a manner presentable to a judicial facility. Computer science skills are instrumental for every examiner.

The usual duties computer forensic experts are expected to perform are divided into three stages. The first and initial stage is the acquirement of a device. The relevant device is initially acquired or a copy made from an image. The device is later made secure and protected from unauthorized access.

The second duty of an scientific investigator after acquiring the device is extracting data found on the device and sorting it out differentiating the relevant and the irrelevant information. Analysis of the data follows while at the same time scrutinizing the information with an aim of filling certain particular puzzles. Reporting is later made by the particular examiner or analyst in such a clear way that will be easy to be comprehended by a common person. Reporting can be done by presentations which should be by any means acceptable in a judicial court.

A virtual systems investigation is yet another concept of the wider computer forensics. In this view, a virtual machine, software functioning similarly to a computing device, is investigated and its data compiled in an understandable manner. Additionally, mobile devices can be used to track down exact locations of criminals or analyze call logs while in the media concept storage devices such as hard disks can provide an important avenue of concluding on a particular case.

Forensic process for computing devices involves clear techniques that can be used to extract data from devices. Cross drive analysis is such one technique where information found on several storage devices may be linked up and a correlation created. Live analysis is yet another technique that may be used which involves obtaining data from within an operating system. Moreover deleted files technique is used to recover deleted files that are suspected to be containing evidence. Operating systems do not entirely erase files thereby easing the retrieval process.

A typical computer forensic process incorporates three distinct stages namely the acquirement of the gadgets, analysis, and scrutiny of data extracted and finally reporting on the findings and conclusions. In the first stage, a media device is acquired or seized from its current handlers or imaged and a similar copy produced. In the second stage, information is obtained through various methodologies and later comprehensive searches are conducted to fill in gaps that may occur. Finally, an examiner writes down a clear report that generally can easily be understood by anyone.

Computer forensic is basically the application of computing, analytical, investigative and analyzing skills in criminal and civil laws. As depicted by this piece, an examiner performs tasks relating to the acquisition of devices, analysis of data and reporting as well as presenting their findings in a detailed and simple manner.
