My role in the investigation was to search the suspects digital evidence to help find more helpful information and advance the case.

If important data is lost, then the entire case can be put into jeopardy and question my ability as the investigator. The use of anti-forensics tools which overwrite, destroy or modify files by the culprits could hinder the investigation, so the threat of this risk must be taken into account. The loss or damage of the physical evidence from which the data was recovered is also an important risk to consider. There is potential for a failure of the hardware involved - this may be the evidence, or even hardware in the computer forensics lab. Legal issues could arise if the opposition believe that my job was done unprofessionally or if I have been biased in favour of the prosecution[7]. Minimizing risks is essential after the identification of the potential risks. Minimizing The Risks It was important that I did everything I could to reduce the risks involved before I proceeded any further. Here are the ways I minimized the risks during this investigation: Preserved evidence securely Documented all findings Maintain chain of custody [5] Stayed with the structured checklist Followed the standardized approach Create backups for all evidence Work off copies of evidence Keep an unbiased view …show more content…

My objective at this stage is to find evidence that will help progress the investigation and potentially lead to further clarity on all aspects of the case.

Where would the potential data be stored? Is there any deleted documents sill stored on the disk? In the cell phones, fax machines and the telephone and voicemail systems yielded little new digital evidence that was relevant to the case. The involvement of the equipment itself however, meant that there was a sophisticated communication system used between the locations. The computers however had a different story. Overall, there were 30 computers that needed to be investigated that were found at the 5 crime scenes. Most of the computers, 25 to be precise yielded some evidence such as product logging details, client lists and sales reports, all of which were found on the computers without the need for forensic tools. The most important and interesting evidence came from 5 of the computers, 1 at each scene. These computers were separated from the others in an office - more than likely a designated office for the manager of

This ultimately results is a subsequent communication which requires the holder to disclose those passwords or taking on an additional task of tracking the passwords. In both the cases, the level of work is expanded and the police investigator has to take on additional tasks then he was initially required to. This while increasing the cost of investigation also increases the time taken in investigation. Therefore while identifying the property, or the hardware of the computer, an inclusion needs to be made in relation to the passwords that may be protecting that hardware. Similarly for the data demanded in the digital format the investigator, would have to highlight that mere data in digital format is not required, but also the passwords or the code's which restrict access to that data are also required.

As far back as 2001 when the first “Digital Forensics Workshop” was held and a case for standards was made, considerable progress has been made in ensuring the growth and expansion of the practice of computer forensics. Mason (2003) suggested the need for standards by which digital forensic practitioners ensure that evidences for prosecuting cases in the law courts are valid as more judgments from a growing number of cases were reliant on the use of electronic and digital evidences in proving the cases. XXXX (2005 & 2007) emphasized the dynamic nature of technology and its impact on the digital forensics field. Hence, the need for having early standards in regulating the
