1 SUMMARY Mobile forensic tools for government and law enforcement extract data for evidence while maintaining data integrity. There are many mobile forensics tools available to choose from that advertise that they are the best. This report compares and contrasts two popular forensics tools: UFED Physical Analyzer (UFED) and Oxygen Forensics Suite 2015 Analyst Edition (OFS). Evaluation of the forensic tools identified UFED Physical Analyzer as the ideal choice. A cost-benefit analysis between the two tools and UFED had favorable results by mitigating the cost of training. Furthermore, extensive testing by the author and software tests performed by the U.S. Department of Homeland Security’s (DHS) Computer Forensics Tool Testing (CFTT) program determined UFED supports more mobile devices without reporting errors. In addition, the most important feature a mobile forensics tool has is the ability to retain integrity. This is especially true if a criminal case used the mobile device as evidence. UFED has been found to do this extremely well, where OFS falls short due to installing a program on the original device. 2 INTRODUCTION The customer requests an evaluation between two popular mobile forensics tools, OFS and UFED. Mobile forensics tools are valuable pieces of software designed to extract information such as contacts, photos, messages, location history, emails, and social media communications off of devices such as cell phones. Evidence in criminal proceedings, corporate espionage cases, and government espionage cases use this information as evidence. Due to the evidentiary value of the recovered data, it is important to have a tool that maintains device integrity. The purpose of the evaluation is to decide which tool would be... ... middle of paper ... ...compared to Oxygen Forensic Suite. However, the training costs per trainee is at a greater cost. Taking into consideration the greater capabilities of UFED, the benefits outweigh the costs. To mitigate training costs, select employees can attend the training and become the trainers within the organization. 7 CONCLUSION & RECOMMENDATION This report presents two alternative tools for mobile forensics: UFED Physical Analyzer, developed by Cellebrite USA Inc. and Oxygen Forensics Suite, developed by Oxygen-Forensics Inc. Each tool features the ability to extract valuable forensic data from mobile devices. However, this report recommends UFED as it was found to support a larger variety of mobile devices while maintaining data integrity. Additionally, it provides superior data extraction throughout the most popular mobile devices with a favorable cost benefits analysis.
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.
Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne particles, insulation, textile fibers, soot, soils and mineral grains, and explosive residues. Although these are the most common found elements, they are not the only ones. The Trace Evidence Unit is known to examine the largest variety of evidence types and used the biggest range of analytical methods of any unit. materials are compared with standards or knowns samples to determine whether or not they share any common characteristics. In this paper I will discuss the different kinds of trace evidence and how crime scene investigaros use it to solve cases and convict criminal.
Hundreds across the nation watch forensic shows every day. From fictional shows similar to Criminal Minds and CSI, to nonfictional shows such as The First 48 and Forensic Files. However, these shows have something in common. Criminological programs continuously show how the crime happened, what it takes to crack the case, how investigators accumulate evidence, a...
There is a wide range of Linux forensic software available. There are single tools like file carvers, or there are comprehensive collections of tools. In the following, some of the most popular Linux forensic tools are described. The focus is put on The Sleuth Kit because it is organized according to the different filesystem layers. This provides an interesting insight on how forensics is done on filesystems.

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human; Working the Scene--Different Stages; and Working the Scene--Different Skills (Genge vii-viii). Included are instructions on what professionals should do upon arriving at a crime scene, what items to bring with them, how to protect the crime scene, and how to protect the evidence from contamination. In addition to writing about the subject of forensic science, the author also included several appendixes and suggested readings to help the reader learn even more information about the subject. In addition, the author included a list of colleges that offer programs in the field of forensic science.
The data a computer forensics acquisition tool collects is stored as an image file in one of three formats. Two formats are open source and the third is proprietary. Each vendor has unique features, so several different proprietary formats are available. Depending on the ...
Mobile devices are being exposed to a record number of security threats with potentially alarming statistics indicating a 400 percent increase in Android malware for example, while Wi-Fi connections are also being increasingly targeted. While the conventional desktop PC will still continue to serve important functions at both consumer and professional levels, there is an expectation that mobile devices will become the predominant form for accessing both personal and professional content it is understandable that cyber criminals have begun focusing on mobile devices which have at the same time grown their user base while substantially consolidating the operating system variants which makes the surface area for a potential attack substantially larger (...
What did they do ? Before we talk about it any further, we have to know some definitions that we use in digital forensics and digital evidence, not only two of them but the others too. This chapter will explain about it . Before we talk about it any further, we have to know the definition of what we are talking about. In the introduction we already know what digital forensic and digital evidence shortly are. In this chapter, we will more explore what they are, and some state that we found when we search about digital forensic and digital evidence. Computer forensics is a broad field and applied to the handling of crimes related to information technology. The goal of computer forensic is to securing and analyzing digital

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice
Digital Forensic is described as “ a forensic science encompassing the recovery and investigation of materials found in digital devices “ (“Introduction to Digital Forensics,” 2011). The objective of digital forensics is to implement a well-structured investigation while preserving a documented chain of custody and evidence custody form to know what really occurred on digital devices and who was accountable for it.
Physical evidence is additionally important in every criminal investigation because too often witness accounts are sometimes biased or unreliable. Physical evidence such as trace evidence, DNA, and fingerprints may objectively attach one or more persons to a victim or suspect to a crime. Favorably, physical evidence can also demonstrate inestimable for exonerating an innocent suspect. Laboratory members and criminal investigators should perform together to resolve the biggest portion of evidence to institute the right suspect for a strong prosecution. Willingly, investigation officers should aggressively contact laboratory personnel when questions arise about the cases because DNA evidence is sensitive.
