The research for this paper revealed several articles containing proposed frameworks that combine the approaches outlined above in the effort of offering the greatest analysis efficiency alongside data privacy protection. This section focuses on outlining the proposed frameworks, the positive aspects, and any known challenges. Gupta (2013) approaches privacy protection during the forensic investigation process by proposing a framework based on the logic that criminal behavior and evidence remains similar from case to case. The framework consists of three modular stages of an Expert System, Evidence Extraction, and Ranking. The Expert System is a database comprised of historical digital crime cases, case profiles, and stored images of the …show more content…
The reduced data process required only 79 seconds to collect the subset from a 320GM hard drive, which presents a significant reduction in time when compared to the time required to forensically image and verify a hard drive using standard forensic bit-by-bit imaging (2014). The proposed methodology presents an efficient solution for reducing data storage requirements while simultaneously reducing the chances of a privacy violation from reviewing unrelated personal information.
Bashir, Khan, and Bhutto (2015) propose a framework for forensic triage clustering techniques that compare the case evidence against a database of blacklisted information containing information over prior malicious attacks. The framework consists of five phases: (1) identification and isolation of the machine under investigation; (2) data imaging, memory dump, log files, and other system activities; (3) extraction of potential evidence files; (4) triage comparison against the blacklist database; and (5) reporting. The blacklist database contains the history of previous malicious malware or cyber-attacks and allows investigators the ability to use clustering to single out any files matching known attack information. Testing successfully showed a reduction in files needing analysis and provided efficiently accessible information on
The legal right is with the officers which allows them to search passenger compartments which are found in the suspect’s vehicle. If officer feels that adequate suspicion exist, they have every right to conduct limited suspect search. Vehicles can be searched by the officials without a warrant, if they have the probable cause with them as per the fourth amendment.
Over the years, in the United States the approach to sex offenders has changed. The criminal justice model doesn’t see sex offenders any different from any other type of crime. Sex offenders are responsible for their actions. In contrast, the medical model see/believe sex offenders as mentally ill with diagnosable sexual disorders. Laws in the United States are based on this model. Offenders are usually admitted to a hospital or a mental health hospital.
Development of this technical evaluation report is the result of a request from a standing Army CPT to fulfill the requirement of expanding the CPTs memory forensics capabilities. The three considerations of cost, capability, and operating systems compatibility are the main points for comparison. The memory forensic tools where compared and contrasted based upon the guidelines that the CPT provided. When comparing the two tools in all three factors of consideration Magnet IEF was the clear winner. The final recommendation of this technical evaluation is that the CPT acquires Magnet
To begin this digital forensic investigation interviews with the Information Technology personnel should be conducted to gather details about the computer systems, components, and network. Interviewing staff will aid in determining the impact the incident has caused to the company such as loss of information and/or profits. During evidence collection SME’s business could suffer major financial losses if computers are moved to a crime lab for an extended period. If possible, an on-site investigation would be most efficient for the company. The investigator will need to collect volatile data related to RAM, log files, caches, and network. To collect nonvolatile data clones of the hard drives may be the best option to prevent interruptions to business operations. Since SME is using Windows Server NT an assessment of the contents of the windows registry can reveal an operators actions, including programs accessed, external tools used, and unfamiliar IP address. After collection of data, an analysis in a forensic lab should be conducted. Using timeline analysis the crime can be reconstructed by examining alterations of files. Throughout this entire process it is essential that proper documentation and chain of custody are maintained. Without this documentation digital evidence may be found irrelevant if court proceedings are necessary. When a timeline is established the investigator may begin sorting through data relevant to the incident. The forensic investigation
Until recently, forensic scientists needed only to study physical evidence to determine what had taken place at a crime scene. This consisted of gathering fibers and samples of any bodily fluids left behind and also taking note of every aspect of the crimes scene to determine what had happened. In today’s age, that is all still necessary for most crime scenes; however, there is a new frontier for criminals to commit illegal acts. This new frontier is the internet. Cyber-crime has become increasingly prevalent in recent years. This rise of new technology is forcing the field of forensic science to adapt in order to investigate cyber-crimes as well. With the advent of personal computers, the science of forensics has been forced to evolve with the times and as a result the field of digital forensics has developed. While many of the same principles can be applied, special considerations in regards to how the 4th Amendment of the Constitution applies to the practice of digital forensics must be taken.
The overall goal of a good theory is to be of assistance in helping one understand crime and how the criminal justice system works. Theories cover the making and the breaking of the law, and also criminal and deviant behavior. Furthermore individual theories may be either macro or micro, along with showing patterns of criminal activity along the way. Theories can also be used to guide policy making, and can be evaluated with a number of different circumstances including: clarity, scope, parsimony, testability, practical usefulness, and empirical validity
Whether it is a criminal or a civil case, an accused should be required to provide his password to the Forensic Examiner for the purposes of decrypting his hard drive. Legal action in the judicial process is dependent on admissible evidence. This suggests that all relevant data should not be withheld by both parties and that each independent piece of evidence must be equally and fairly evaluated in the judicial system before legal action ensues (barristerharri, 2012).
Some of the most important procedures used in collection of information to be used in a court of law include collecting live data from the RAMs images. Such live recovery of information can be collected from the F-Response which can collect data from the networks of a computer. Information can be collected when the computer is logged on or connected to the network or when the computer is executing (Carrier, 2006, p. 56). The other procedure that can be used in the collection of information for forensic purposes is the encryption of hard disks. Encryption of the hard disk creates logical images that can be collected using the F-Response (Eoghan & Gerasimos, 2008, p. 95). The other important procedure for collection of information is making sure that all data storage devices are kept away from magnets and any other devices that might destroy data stored in them. It is important that the handling individuals obtain the information collection manuals that help them collect information effectively (Eoghan & Gerasimos, 2008, p. 94).
“In 2003, two students from MIT bought 158 used and formatted disk drives from a wide variety of locations. From there they were able to extract over 5,000 credit card numbers, secret corporate financial information, detailed personal and medical information, along with many gigabytes of personal emails and pornography” (Sherweb, 2010, para 2). Computer forensic tools are used to find out and analyzing available, deleted, or hidden information that may be used for evidence in a legal matter. These forensic tools allows the user to uncover potential evidence that someone else does not want to be discovered. This
The IoT will create unique circumstances in the already established digital forensic process. Trained, qualified professions execute digital forensic investigations with the assistance of tools and techniques to acquire and analyze data. These tools are carefully tested and reviewed by peers and experts before use in the field, to ensure the evidence collected with these tools will be accepted in a court of law. "Among the existing methodologies are the 4-stage Computer Forensic Investigative Process and the 13-stage Extended Model of Cybercrime Investigation" (Oriwoh 609). These methods outline the basic procedure for preparing, examining, presenting, and storing the evidence. IoT investigations will differ in the breadth, and technical
In this paper, I review some relevant current challenges and future of digital forensic. Section 2 tell about current challenges such as IoT and Cloud Computing. Section 3 analyze the current challenges. Section 4 provides the future direction of digital forensic. Lastly section 5 the conclusion of this paper.
In this week’s class, we learned about the difficult situations that might arise when dealing with the criminal justice system and such things as trauma, mental health illness, and substance misuse. In addition, great emphasis was put on displaying resilience towards these situations in order to ensure that we make our self-care of utmost importance, and to guarantee our success in the criminal justice system (Abramson, 2017, Lecture on Mental disorders, trauma, and substance misuse). Furthermore, the knowledge and skills I have learned throughout the class and from the conference on dealing with trauma, mental illness, and substance misuse, will hopefully aid myself in the criminal justice system, as it is likely that I will be exposed to
I hereby certify that this material, which I now submit for assessment on the programme of study leading to the award of Degree of Honours B.Sc. in Cyber Security & Digital Forensics in the Institute of Technology Blanchardstown, is entirely my own work except where otherwise stated, and has not been submitted for assessment for an academic purpose at this or any other academic institution other than
The rest of the paper is organized into various different sections as follows. In section 2, we give a brief outline of the approaches for securing both the audit log files and well as the audit logs server along with other security mechanisms. The third section includes a brief study of how we can index and retrieve the data for any forensic investigation which may be quite essential in a fast paced criminal investigation. The fourth section discusses in depth about the use of the valuable information uncovered using log files and how they can help us find important patterns.
Service learning at the Orleans Public Defenders was eye opening. I worked as a client services intern, and it was strange because even though I did the same thing each week, how it happened or the cases I would hear was always interesting and different. Usually court would start at 9:30a or 10:00a depending on the judge or 11a if the judge was delayed. I would work with my supervisor to prepare the files that the lawyer would need for the preliminary hearing and walk over to the courthouse. Once there, I asked clients for contact numbers so we could call the requested people about their bond, and then, I would take notes on each person’s case so we could make a memo after the arraignment for OPD reference.
