...Abstract Mobile forensics involves recovering and retrieving digital evidence or data from mobile devices under forensically sound conditions utilizing established methods (Ayers, Brothers, & Jansen, 2013). The field of mobile forensics is complicated as the variety in providers, manufacturers, propriety technologies and formats are extensive. These challenges are coupled with the fast release and upgrades to mobile devices making a forensic investigator’s job more arduous in attempting to examine and analyze these devices for the purpose of recovering data and evidence (Martin, 2008). This white paper will focus on the challenges of mobile device technology, the methodology utilized in examining these devices to recover data which is crucial to security investigations; which includes the tools, techniques and procedures necessary for gathering data from various similar devices. This paper will also focus on the training and expense of acquiring efficient forensic investigators and, as well as impending approaches for addressing challenges. Introduction “The goal of mobile forensics is the practice of utilizing sound methodologies for the acquisition of data contained within the internal memory of a mobile device and associated media providing the ability to accurately report one’s findings” Mobile devices, contrary to popular belief, includes an array of devices not limited to cellular phones and smartphones, but also include table devices, mp3 players, digital cameras...

...Abstract: Advanced cyberattacks on the public and private sectors at the local, national, and international level have prompted an increase in funding and support for the study of emerging cybersecurity technologies. The considerations for this paper are to discuss the emerging technologies and strategies that can be integrated across the public and private sector to improve cybersecurity on a local, national, and international level. New technologies need to dynamically assess networks real-time such as with the use of Remote Agents and Real-time forensic analysis. These technologies also need to make the attack space less predictable and constantly evolving such as through the use of moving target defense. Emerging Cybersecurity Technologies The E-government Act of 2000 was signed by President Bush to move toward a more 24-7 government. The dream was to eliminate the need to have to stand in line at the DMV for half a day just to pay annual vehicle registration fees (Barker, 2011). Security was certainly a concern, but it was not at the forefront of the move as government agencies would go through massive changes in equipment, manning, and practices in order to move information and programs online. Now, over a decade later we still see moves and changes taking place, such as the department of Veterans Affairs recently moving all of their applications, forms and records online. The expensive cost of getting the government caught up was expected with such an overhaul...

...Digital Forensics is an important aspect to computer systems security. I mean we are talking about Identifying, Collecting, Preserving, Analyzing, and Presenting evidence digitally. Therefore, preserving electronic evidence is important. Investigating Data Theft is a malice act towards a company/ organization (Kruse, 2001). Such theft is made by an employee that is either terminated or resigning. Motives for data theft include setting up a competing business, using the information at a new job, sense of ownership of what was created, and revenge against the employer, among other things. Common Theft include, customer information, financial records, software code, email lists, strategic plans, process documents, secret formulas, databases, research and development materials, and employee records. Now, with such theft around, we often wonder how is such theft achieved. Knowing how technology is always advancing each year, the millennium era grows with fascinating knowledge on the know how to working a computer, hard drives, etc. Tools like flash drive, which can hold thousands of documents that can be copied to the flash drive, and taken anywhere. Then you have Dropbox, remote desktop connections, personal email accounts, smart phones, CD’s/DVD’s, and FTP ( File Transfer Protocol ) (Kruse, 2001) There is always this saying, that personnel who steal data often leave a trail of digital evidence that proves invaluable when investigating data theft.

...1)Introduction; Crime today is at an extreme high. However, forensic science has been there to help solve every crime committed Forensic science is the scientific method of gathering and examining information about the past. The word forensic comes from the Latin forēnsis, meaning "of or before the forum. The word forensic basically means the key to solve a crime.This is the technology used to help forensic teams to analyze and solve crimes.- This is especially important in law enforcement where forensics is done in relation to criminal or civil law,[1] but forensics are also carried out in other fields, such as astronomy, archaeology, biology and geology to investigate ancient times. Forensic Science is used to Identify Criminals Rape, murder, theft, and other crimes almost always leave a devastating mark on the victim. . In modern forensic science, the crime laboratories include photography section, Evidence storage section, identification section, chemistry section, General examination section, Fire arms section, instrument section and crime scene search section. 2)Origins of forensic science: In 16th-century Europe, medical practitioners in army and university settings began to gather information on the cause and manner of death. Ambroise Paré, a French army surgeon, systematically studied the effects of violent death on internal organs.[9][10] Two Italian surgeons, Fortunato Fidelis and Paolo Zacchia, laid the foundation...

...FORENSICS Forensics, by and large, is the application of science to the legal process. It is an emerging research domain in India. There are many different types of forensic sciences baring their vital presence possibly in every field of human endeavor. Of these, let us now discuss about the computational, cyber and the DNA forensics. COMPUTATIONAL FORENSICS: The development of computational methods or mathematical and software techniques to solve forensic issues is called computational forensics. These methods analyze the evidence beyond human cognitive ability. They scrutinize a large volume of data, which is at any case impossible for a human mind to figure out. In spite of this, we can’t say that these techniques alone would serve our purpose because computational forensics is a field which needs huge collaboration between recognition and reasoning abilities of humans combined with comprehension and analytic abilities of the tool or a machine, which is most of the times, a computer. Computational forensics aids us to model the uncertain. At the crime scenes, we usually get incomplete or broken evidences. These evidences are later on modeled by the computational forensic tool which gives us first clues from its largest biometric database (fingerprints, criminal histories, mug-shots, scar and tattoo, physical characteristics like height, weight, hair and eye color and aliases), which is a collection of significant information regarding the criminals, their criminal history...

...Undelete 360 is the free version of a commercial product, and so leaves out some useful features (file filtering, previews and so on). These still appear in the interface, though, and suggest you upgrade if you ever click on them, which can be annoying. There are no restrictions on the amount or size of the files you can recover, though, and otherwise the program is very simple to use: point it at a drive, it'll scan for deleted files, then you can view particular file types (JPGs, PDFs, videos and more) by choosing them from a tree. Scanning speed isn't great, but Undelete 360 can recover files that other programs miss, and so it's definitely worth considering [ (Williams, 2013) ]. Standard undelete programs are perfect for recovering a few files, but if you've lost an entire partition then you'll probably benefit from a specialist application like MiniTool Partition Recovery. The free (for personal use) program has a wizard-based interface which makes it very straightforward to use. Point MiniTool Partition Recovery at the problem drive, specify the area to be searched, and it'll scan for the missing partition. A report will let you know what the program has found, and you can recover the partition in a few seconds. You don't get a bootable recovery disc here, so if your system partition is damaged then MiniTool Partition Recovery won't help you very much. Otherwise, it provides a quick and easy way to locate and restore lost partitions [ (Williams, 2013) ]. A tool called...

...found. It will be discussed having the implications of poor packaging and the results which lead to contamination of all evidence if not packaged properly and the outcome when it is taken to court also the reliability of the CSI’s involved. It is also the job of the CSI to make sure all health and safety procedures are in place before handling and taking any piece of evidence as there are varying risks involved like sharps, contamination of evidence, weather conditions other witnesses interfering with the scene, other personnel and any form of biological hazards. These must be taken seriously and analysed before any search. Unit 5 1. Detail the forensic evidence that would have been taken away from the scene by the perpetrator. The crime scene is probably the most important part of any criminal investigation. It is where forensic science starts. Locard’s Principle states that every contact leaves a trace (Locard, 1928). This is the primary rule of scene investigation – you are looking for ‘contact’ evidence that will help solve the crime. This trace may be in the form of a specific recoverable material, such as a chip of paint, or that of a mark or impression, such as a fingerprint. This physical evidence must be protected against loss and contamination and be...

...Welcome to Homicide Forensic Science is a fundamental component of the justice system. Forensic scientists use scientific techniques and knowledge to assist law enforcement in investigations and solving crimes. They collect and analyze numerous types of evidence, including blood, body fluids; DNA; and human tissue. Forensic scientists assist the decision makers by showing the prosecutor if the issue has merit before it reaches the courtroom thereby reducing the number of cases having to be heard. Their decisions are based on scientific investigations and not circumstantial evidence or unreliable witnesses. Forensic scientists can restore faith in the judicial system with the use of science and technology for facts in criminal and civil investigations. The legal system is established on the belief that the legal process results in justice for all. History of forensic science The history of Forensic science or the applying of scientific principles to legal questions has a lengthy and interesting history. The first recorded autopsy was reported in 44 B.C was on Julius Caesar, where the Roman physician, Antistius proclaimed that he had 23 wounds on his body but only one was fatal. In 1248, a Chinese book entitled “His Duan Yu” (meaning The Washing Away of Wrongs) explaining how to tell apart a drowning from a strangulation. This was also the first recorded use of medicine to assist in solving crimes. In 1590, the first microscope was developed. In 1775, Karl...

...Expert Witness Helped Convict Wrong Man A panel of six independent forensic scientists stated, in a report filed in a Houston State court, that crime laboratory supervisor James Bolding helped convict an innocent man of rape in 1987. Because Bolding either lacked basic knowledge of blood typing or gave false testimony, George Rodriguez spent 17 years in prison for a rape that he did not commit. Bolding’s testimony in the case was challenged amid a scandal that led to retesting of evidence in 360 cases; And with the report filed, that number could increase by the thousands, involving 25 years of cases. “The panel concluded that crime laboratory officials might have offered ''similarly false and scientifically unsound'' reports and testimony in other cases, and it called for a comprehensive audit spanning decades to re-examine the results of a broad array of rudimentary tests on blood, semen and other bodily fluids” (Liptak and Blumenthal, 2004). There have been many cases where forensic science and law enforcement experts have provided sworn testimony, documents, or reports intended for the court that contain unreliable or misleading information, findings, opinions, or conclusions. Some are found to have been intentionally offered by the expert in order to secure an unfair or unlawful conviction, via ‘fitting the evidence to the crime’. A state audit of the Houston police department (HPD) crime lab, completed in December 2002, found that HPDs DNA technicians there...
