Digital Forensic Investigation (DFI), LLC has been contracted by American Marketing Systems (AMS) to perform a clandestine investigation of a suspected internal skimming operation involving an unknown number of employees in its marketing department or accounts receivable. AMS has just become aware of this predicament, but are unaware of the how the skimming operation is being conducted. DFI has been contracted by AMS to ascertain if a skimming operation exists, and if so, who is implicated and…

Illustrate the differences between digital forensics and network forensics. Digital forensic:  Digital forensic is a branch of forensic science and it talks about the recovery and investigation report found in the digital devices.  Digital forensics is about the "preservation, identification, extraction, documentation and interpretation of computer data"  In order to accomplish these goals, there are well-defined procedures, also derived from law enforcement, for acquiring and analyzing the…

grown exponentially, be it hard drives in personal computers and laptops or solid state memories in mobile devices such as smartphones and tablets, even while idleness times linger behind. This paper discusses four best sources of data that forensics experts hunger to get their hands on. They are log files, hard drives, mobiles devices, and social networking websites. Each of these sources has its own characteristics and techniques that the forensic investigators can use to explore hidden…

Windows registry is an excellent data source for digital forensic analysis because it is one of the quickest and most efficient uses of the forensic investigators time to decide whether a particular computer is of value to an investigation (especially in cases where multiple unknown computers are of interest). It can contain very rich data about an investigation without too much research and troubleshooting. The Windows registry two main task for the operating system; it stores all the setting…

According to Brian Carrier, a digital forensic investigation is a special case of a digital investigation where the procedures and techniques that are used will allow the results to be entered into a court of law. According to university lecturer Andrew Jones, there are four underling principles of Digital Forensics. They are as follows: • Principle 1: No action taken by law enforcement agencies, persons employed within those agencies or their agents should change data that may subsequently be…

commonplace for twenty to thirty years. In 2000, United States v. Scott‐Emuakpor set the precedent when collecting digital evidence, and that was that it was only necessary for testimony of a witness who was present while data was collected from computers for it to be admissible as evidence. Sounds ridiculous in hindsight, know what we know now of the common knowledge of rights to digital privacy. In this case, as an investigator, while waiting for access to the computer’s hard drive, I might…

The discipline of forensic science has been under fire for quite some time now, and one can say that it is completely justified. Fraudulent and incompetent analysts, such as Annie Dookhan, have performed investigations in flawed crime labs, like that of the Baltimore crime lab, and through this process, have imprisoned the innocent, just as Cameron T. Willingham was falsely convicted. Issues occurred in all of these instances that allowed for the devaluing of the field of forensic science. If…

Forensic Science was never something I saw myself loving, let alone wanting to do as a career. It wasn’t even a thing to me until my senior year of high school. I’ve always wanted to be a music teacher because I love music and the ways it can change people, but that all changed in the middle of my senior year when I fell in love with Forensics. I want to be a Forensic Scientist because I want to change people’s lives and the way the world looks at science when it comes to investigating and…
