...computer forensics Background of Computer forensics: What is most worth to remember is that computer forensic is only one more from many forensic subdivisions. It’s not new, it’s not revolution.. Computer forensics use the same scientific methods like others forensics subdivisions. So computer forensics is not revolution in forensic science! It’s simple evolution of crime techniques and ideas. Forensic origins: Forensic roots from a Latin word, “forensic” which generally means forum or discussion. In the reign of the Romans, any criminal who has been charged with a crime is presented before an assembly of public folks. Both of the complainant and the defendant are to present their sides through their own speeches. The one who was able to explain his side with fervent delivery and argumentation typically won the case. It is important to realize that computer forensics is only one subdivision of forensic science. It is digital, it includes most advanced computer science but still it is only branch of forensic science, an its main goal is submission of the proven claims of scientific methods and strategies to recover any significant digital traces. Computer Forensic Timeline: 1970s • First crimes cases involving computers, mainly financial fraud 1980’s • Financial investigators and courts realize that in some cases all the records and evidences were only on computers. • Norton Utilities, “Un-erase” tool created • Association of Certified Fraud...

...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...

Forensics is the process of using scientific knowledge for collecting, analyzing, and presenting evidence to the courts. (The word forensics means “to bring to the court.”) Forensics deals primarily with the recovery and analysis of latent evidence. Latent evidence can take many forms, from fingerprints left on a window to DNA evidence recovered from blood stains to the files on a hard drive. Because computer forensics is a new discipline, there is little standardization and consistency across the courts and industry. As a result, it is not yet recognized as a formal “scientific” discipline.

...Assignment 1: Computer Forensics Overview CIS 417 Computer Forensics Computer forensics is the process of investigating and analyzing techniques to gather and preserve information and evidence from a particular computing device in a way it can be presented in a court of law. The main role of computer analyst is to recover data including photos, files/documents, and e-mails from computer storage devices that were deleted, damaged and otherwise manipulated. The forensics expert’s work on cases involving crimes associated with internet based concerns and the investigations of other potential possibilities on other computer systems that may have been related or involved in the crime to find enough evidence of illegal activities. Computer experts can also use their professional knowledge to protect corporate computers/servers from infiltration, determine how the computer was broken into, and recover lost files in the company. Processes are used to obtain this information and some of the processes are as follows; * Investigation process: Computer forensics investigations will typically be done as part of a crime that allegedly occurred. The first step of the investigation should be to verify that a crime took place. Understand what occurred of the incident, assess the case, and see if the crime leads back to the individual. * System Description: Next step, once you verified the crime did occur, you then begin gathering as much information and data about the specific...

...Assignment 4 Computer Forensic Tools Derek Jackson Computer Crime Investigation Professor: Dr. Jessica Chisholm 03/06/2016 When purchasing computer forensics tools and resources for a company, you always want to make sure you are doing the necessary research and determining which of these programs are the best options for the company. This is very important job in any company as you are in charge of not only protecting the company’s data with these tools, but also recovering any information that may have been lost or deleted. There are many programs that are available that can be used to recover deleted files. Two of the programs that you could use are the MiniTool Partition Recovery and PC Inspector File Recovery. The MiniTool Partition Recovery is a free program that has a wizard-based interface which makes it very easy and straightforward to use and understand. You can point the MiniTool Partition Recovery at the problem drive, specify the area to be searched, and it will scan for the missing partition. Then a report will generate that will let you know what the program has found, and you can then recover that partition in a few seconds typically. The only downfall is that you won’t get a bootable recovery disk, so if the partition is damaged then the MiniTool Recovery program won’t be able to recover the deleted partition. The PC Inspector File Recovery allows you to be able to recover a full set of missing files on both FAT and NTFS drives. They are clearly...

...International Journal of Digital Evidence Fall 2007, Volume 6, Issue 2 Computer Forensic Analysis in a Virtual Environment Derek Bem Ewa Huebner University of Western Sydney, Australia Abstract In this paper we discuss the potential role of virtual environments in the analysis phase of computer forensics investigations. General concepts of virtual environments and software tools are presented and discussed. Further we identify the limitations of virtual environments leading to the conclusion that this method can not be considered to be a replacement for conventional techniques of computer evidence collection and analysis. We propose a new approach where two environments, conventional and virtual, are used independently. Further we demonstrate that this approach can considerably shorten the time of the computer forensics investigation analysis phase and it also allows for better utilisation of less qualified personnel. Keywords: Computer Forensics, Virtual Machine, computer evidence. Introduction In this paper we examine the application of the VMWare (VMWare, 2007) virtual environment in the analysis phase of a computer forensics investigation. We show that the environment created by VMWare differs considerably from the original computer system, and because of that VMWare by itself is very unlikely to produce court admissible evidence. We propose a new approach when two environments, conventional and virtual, are used concurrently and independently. After the images...

...this research paper was to analyze three anti-forensic techniques for potential methods of mitigating their impact on a forensic investigation. Existing research in digital forensics and anti-forensics was used to determine how altered metadata, encryption, and deletion impact the three most prominent operating systems. The common file systems for these operating systems were analyzed to determine if file system analysis could be used to mitigate the impact of the associated anti-forensic technique. The countermeasures identified in this research can be used by investigators to reduce the impact of anti-forensic techniques on an investigation. Also, the results could be used as a basis for additional research. File system analysis can be used to detect and mitigate the impact of the three methods of anti-forensics researched under the right circumstances. Some areas of anti-forensics and file systems have been relatively well-researched. However continued research is necessary to keep pace with changes in file systems as well as anti-forensic techniques. Keywords: Cybersecurity, Albert Orbinati, Windows, Linux, Macintosh, file table.

...Computer Intrusion Forensics Research Paper Nathan Balon Ronald Stovall Thomas Scaria CIS 544 Abstract The need for computer intrusion forensics arises from the alarming increase in the number of computer crimes that are committed annually. After a computer system has been breached and an intrusion has been detected, there is a need for a computer forensics investigation to follow. Computer forensics is used to bring to justice, those responsible for conducting attacks on computer systems throughout the world. Because of this the law must be follow precisely when conducting a forensics investigation. It is not enough to simple know an attacker is responsible for the crime, the forensics investigation must be carried out in a precise manner that will produce evidence that is amicable in a court room. For computer intrusion forensics many methodologies have been designed to be used when conducting an investigation. A computer forensics investigator also needs certain skills to conduct the investigation. Along with this, the computer forensics investigator must be equipped with an array of software tools. With the birth of the Internet and networks, the computer intrusion has never been as significant as it is now. There are different preventive measures available, such as access control and authentication, to attempt to prevent intruders. Intrusion detection systems (IDS) are developed to detect an intrusion as it occurs, and to execute countermeasures when detected...

...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...
