Author Date Affiliated Institute Securing Evidence and Imaging Introduction A complaint from the Unit Manager, Mr. Roger Ellis suggests possible illicit chat activity related to eBay fraud by designated user id (MalcoMind). The primary task in this investigation lies in the seizure and safe storage of the evidence. The secured evidence should then be imaged prior to examination. The other requirements include gloves, forensic toolkit for fingerprinting, labels, storage packets for cables, tamper-proof containers for transporting the CPUs and forms: inventory of items seized, crime scene photos and notes on search of the surrounding area. Warrant Execution The search warrant was executed at 9:30 am at the residence of Mr. Corrigan …show more content…
A wireless modem, three external HDD and two pen drives. All these items are photographed with the serial numbers recorded on the inventory forms. Evidence gathering The keyboards of the laptops and desktop, the two mouse devices, the CPUs, pen drives, external HDDs and modem were scanned for fingerprints or any other physical evidence (hair, fiber, etc). The laptops were then turned off by pressing the power button. The CPUs were switched off directly from the switchboard powering them. All three external HDDs are stored in paper bags brought to the scene and have been labeled. The cables have been stored in plastic bags and labeled separately. The CPUs are stored in the special containers that we brought along to avoid magnetic interference. The two laptops are stored in laptop bags that were provided by the forensic lab. One of the drawers contained an Apple iPhone and iPod, a Dymo label printer, a Samsung voice recorder and a metal gear box. The contents were photographed, dusted for prints and gathered for evidence. (Janet 2012) Note: The suspected scene of the crime was photographed before any physical contact
Digital Forensic is the process of uncovering and interpreting electronic data that can be used in a court of law. It requires a set of standards to show how the information that is gathered, preserve, and analyzed is strictly followed. The analysts need to understand the evolution of the current technology and how it will impact how they gather their information. The investigator is able to uncover evidence and analyze it to gain the understanding of the motives, crime, and the criminal’s identity to help solve the crime. As computers and technology continue to become a part of our everyday lives, the cyber realm contains a growing realm for evince in all types of criminal investigations (Cummings, 2008) Digital forensics is a way to connect information security and law enforcement. It ensures that the digital evidence is collected in a way that it can make it into the courts in an unhampered or uncontaminated way (Dlamini, M., Eloff, J. & Eloff, M., 2009).
Forensics investigations that require the analyzation and processing of digital evidence can be influenced both positively and negatively by a number of outside sources. In this paper, we will explore how physical security plays a role in forensics investigations activities. We will start by examining how physical and environmental security might impact the forensics investigation process. Next, we will discuss the role that physical and logical security zones play in supporting effective forensics activities. We will illustrate how centralized and decentralized physical and environmental security affects the forensics professional’s approach toward the investigation. Lastly, we will evaluate some potential areas of risk related to the physical security of our case study organization, Widget Factory, identified in Attachment 1.
Computers are also unique in the way they type and print out things. Document examiners can look over these and establish the similarities in the handwriting, and computer forensic specialists can extract logs and other data from most devices. As you can see

A forensic evaluation is a comprehensive and elaborate process that incorporates collection, analysis, and integration of information form multiple sources. Child welfare related evaluations are one of the most complex types of forensic evaluations requiring expert opinion and recommendations on matters pertaining to child custody and visitation, parental fitness and termination of parental rights, and evaluation of adoptive and foster parents. The primary purpose of these evaluations is to inform the court and facilitate decision-making process in child welfare cases. During a child custody evaluation the main doctrine to uphold is the “best interest of the child.” The safety of the child is of paramount consideration. This along with well-being

Technology has opened new encounters and opportunities for the criminal justice system. There are so many new practices of criminal activity, such as computer crimes. There are different types of computer crimes that many people become victims of every day. Computer crime is any crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target ("Computer Crime: Chapter 2: What Are the Crimes?", n.d.). Crimes such as data diddling, pump and dump, social engineering and spoofing are computer crimes. Even though these crimes are difficult by privacy issues, the new technology has made investigations and prosecutions well organized and effective. Though views are different on the pros and cons of specific technological changes in the criminal justice system, there is an agreement the system has changed affectedly ("Effects of Technology in Criminal Justice | eHow", n.d.).
In order for evidence to be used in court, it must be collected and tested by valid methods. The collection of evidence must be completed carefully and properly to prevent cross-contaminating or destroying the evidence. Before evidence can be collected at a crime scene, the area must be secured to ensure everyone stays safe and that the evidence is not destroyed. After the scene is secured by all proper measures, the collection process can begin. The first items to be collected are those that are transient, fragile or perishable. Hair, fibers and small shards of glass are all

The use of computers in homes, schools, offices, and other places has increased in the past few years due to technological developments. As computers have become important components of modern communication, their increased use has also led to the emergence of computer crimes. Computer crimes basically involve the use of a computer system to carry out an illegal activity. In attempts to lessen the frequency and impact of computer crimes, law enforcement agencies use computer forensic to investigate these offenses. Actually, computer crimes are governed by specific laws and dealt with through conducting a computer forensic investigation (Easttom & Taylor, 2011, p.337). Notably, a computer forensic investigation is usually carried out through the use of computer forensic tools, which help in collection of evidence based on the specific offense.
Live acquisition: The future of data acquisitions is shifting toward live acquisitions because of the use of disk encryption with newer operating systems (OSs). In addition to encryption concerns, collecting any data that’s active in a suspect’s computer RAM is becoming more important to digital investigations. The processes and data integrity requirements for static and live acquisitions are the same. The only shortcoming with live acquisitions is not being able to perform repeatable processes, which are critical for collecting digital evidence.
Information about any item, related to the criminal, found at the crime scene (weapons, proofs, if any)

These types of crimes have become a matter of importance for the consumers as well the business firms because it involves large eviction of the amount in terms of money. In these types of crimes, computer and Internet are the primary factor (Spinello, 2000). A high percentage of population is using computers in the Australia, United States as well as other developed nations. These people are much more connected with the world by the use of internet. They are using the computer for fun, business, e-commerce, e-marketing, etc.; thus, it has become an essential part of life and daily routine (Wall, 2008).
