Digital Forensics



Digitalforensics is the process of uncovering and interpreting electronicdata with the intentions of preserving evidence gathered in its mostoriginal form while at the same time reconstructing past events(Sammons,2012).Individuals charged with forensic investigations always follow a setof outlining the procedures. The first step is always to isolate thedevice in question so as to ascertain that it cannot be in any waycontaminated. From here, the investigators make a digital copy of thedevice’s storage media. As soon as the original media has beensuccessfully copied, it is then locked in a safe so as to maintainits originality. It is from here that all investigations are thenconducted (Li,2010).

Digitalforensics is related to the criminal justice system by providingevidence in criminal cases. Evidence obtained through the successfulimplementation of computer forensics has been applied to criminal lawcases. During court proceedings, evidence obtained from digitalforensic is subjected to the typical requirements for digitalevidence, meaning that at all times the evidence provided must bereliable and properly authenticated. The field of digital forensicsrelates to the criminal justice as it provides the right avenue forfighting crimes that would otherwise be hard to deal with.

Digitalforensics has been successfully been indispensable in the convictionof many well-known criminals such as terrorists and murders. Manyterrorist organizations today prefer to use the internet to go abouttheir business, and this is where investigators from forensicdepartments can pin them down without them even knowing. Manycriminals today operate under the assumption that they are good atwhat they do, but the simple mistakes that always do is what forensicscientists use to build their case. Deleting of files does notnecessarily mean that the file is lost forever. Such files can easilybe retrieved in their original form.

Digitalforensic also incorporates the use of Global Position System (GPS)that are embedded in most of today’s Smartphones as well assatellite navigation. This avenue has enabled many suspects andculprits of crimes to be tracked down and eventually prosecuted fortheir crimes. In situations where the GPS cannot prove a suspect’smotives or if they were involved in a particular crime, the use ofGPS has been used many times to confirm a hunch which has seen manyvictims being prosecuted (Webb,2014).Digital forensic also relates well with the criminal proceeding wherethe evidence collected is used either to support or oppose ahypothesis before a criminal court. In other cases, the evidencecollected is used a part of intelligence gathering that may be usedfor other purposes than court proceedings such in halting othercrimes.

Thereis a high need for non-criminal justice majors to study digitalforensic as it will come in very handy in their profession. Anon-criminal justice major deal with a lot of information as such,information authentication will come in very handy. Gathering ofuseful Intel by use of digital will help them unravel most of thedead end cases. In cost other cases, when doing an investigation, onecould feel that they have hit a dead end and they cannot do anythingabout it. But with knowledge of digital forensics one will know thatwhen approach and tool bear no significant results, he or she can useother approaches and tools that might help shade more intelligence(Chen,2013).

Despitethe fact that the field of digital forensic faces a number ofchallenges in as far as the constitution is concerned, itsimplications and effects on the criminal justice cannot beunderestimated. In the near future, more and more cases will behandled with the help of digital forensic investigators.
