Computer forensics Wikipedia. Computer forensics analysis is not limited only to computer media. Computer forensics also known as computer forensic science1 is a branch of digital forensic science pertaining to evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the digital information.

The discipline involves similar techniques and principles to data recovery, but with additional guidelines and practices designed to create a legal audit trail. Evidence from computer forensics investigations is usually subjected to the same guidelines and practices of other digital evidence. It has been used in a number of high profile cases and is becoming widely accepted as reliable within U. S. and European court systems. OvervieweditIn the early 1. At the same time, several new computer crimes were recognized such as hacking. The discipline of computer forensics emerged during this time as a method to recover and investigate digital evidence for use in court. Since then computer crime and computer related crime has grown, and has jumped 6. Microsoft Research Alumni Network.

Today it is used to investigate a wide variety of crime, including child pornography, fraud, espionage, cyberstalking, murder and rape.

JPEG image. 3 The scope of a forensic analysis can vary from simple information retrieval to reconstructing a series of events. In a 2. 00. 2 book, Computer Forensics, authors Kruse and Heiser define computer forensics as involving the preservation, identification, extraction, documentation and interpretation of computer data. They go on to describe the discipline as more of an art than a science, indicating that forensic methodology is backed by flexibility and extensive domain knowledge. However, while several methods can be used to extract evidence from a given computer the strategies used by law enforcement are fairly rigid and lack the flexibility found in the civilian world. Use as evidenceeditIn court, computer forensic evidence is subject to the usual requirements for digital evidence. This requires that information be authentic, reliably obtained, and admissible. Different countries have specific guidelines and practices for evidence recovery. In the United Kingdom, examiners often follow Association of Chief Police Officers guidelines that help ensure the authenticity and integrity of evidence.

Computer forensics has been used as evidence in criminal law since the mid 1. BTK Killer Dennis Rader was convicted of a string of serial killings that occurred over a period of sixteen years. Towards the end of this period, Rader sent letters to the police on a floppy disk.

Dr. Conrad Murray Dr. Conrad Murray, the doctor of the deceased Michael Jackson, was convicted partially by digital evidence on his computer. This evidence included medical documentation showing lethal amounts of propofol. Forensic processedit. A portable Tableau write blocker attached to a Hard Drive. Computer forensic investigations usually follow the standard digital forensic process or phases acquisition, examination, analysis and reporting. Investigations are performed on static data i. This is a change from early forensic practices where a lack of specialist tools led to investigators commonly working on live data. TechniqueseditA number of techniques are used during computer forensics investigations and much has been written on the many techniques used by law enforcement in particular. See, e. g., Defending Child Pornography Cases. Cross drive analysis. A forensic technique that correlates information found on multiple hard drives. The process, still being researched, can be used to identify social networks and to perform anomaly detection. Live analysis. The examination of computers from within the operating system using custom forensics or existing sysadmin tools to extract evidence. The practice is useful when dealing with Encrypting File Systems, for example, where the encryption keys may be collected and, in some instances, the logical hard drive volume may be imaged known as a live acquisition before the computer is shut down. Deleted files. A common technique used in computer forensics is the recovery of deleted files. Modern forensic software have their own tools for recovering or carving out deleted data. Most operating systems and file systems do not always erase physical file data, allowing investigators to reconstruct it from the physical disk sectors. File carving involves searching for known file headers within the disk image and reconstructing deleted materials. Stochastic forensics. A method which uses stochastic properties of the computer system to investigate activities lacking digital artifacts. Its chief use is to investigate data theft. Steganography. One of the techniques used to hide data is via steganography, the process of hiding data inside of a picture or digital image. An example would be to hide pornographic images of children or other information that a given criminal does not want to have discovered. Computer forensics professionals can fight this by looking at the hash of the file and comparing it to the original image if available. While the image appears exactly the same, the hash changes as the data changes. Volatile dataeditWhen seizing evidence, if the machine is still active, any information stored solely in RAM that is not recovered before powering down may be lost. One application of live analysis is to recover RAM data for example, using Microsofts COFEE tool, windd, Windows. SCOPE prior to removing an exhibit. Capture.
