The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure flowchart and acquisition of digital evidence flowchart is shown on Figure 2 and Figure 3 respectively. During this process the investigators should carefully search for all forms of potential electronic evidence that they do have permission to take such as: USB (Universal Serial Bus) storage media, optical discs, mobile phones, tablets, laptops, SD (Secure Digital) and similar cards, NAS (Network-Attached Storage). Other forms of forensic evidence should be also considered such as: fingerprints and DNA before collection of devices, passwords, notes, paper documents, and other information relevant to the investigation. The process of dead forensic is simple, reliable and thorough. The main strength of the dead forensic is precisely defined process of acquisition. The acquisition process can be verified at any time. The process of dead forensic acquisition is simple and does not require very strong programming knowledge. If the acquisition process is strictly followed by the
This would require that a detailed description be given of the data that is the content of the computer which may have been removed from the computer and stored
4.7.5 Data Preservation and Isolation from the Network. The main purpose of a digital forensic report is to keep the data integrity, avoiding any type of data alteration, in order to present valid evidences, for instance in a court. The use of not valid software to check the stored information in a mobile phone can alter these information. The action of receive new data can alter the information stored, for instance an automatic firmware update, or remote device control with the risks involved. Therefore, it is extremelly important have the device completely isolated from the network.
During the comprehensive forensic examination Assante’s personal laptop was subjected to an eighteen hour intrusive search using specialized equipment to open and read all files on the laptop, scanning the unallocated space on the hard drive for deleted files, then proceeding to
There were cameras in their apartment unit at the time of her death, the accused told the police how to operate the security system but did not tell them about the hard drive. By the time they knew about it, it was gone. The hard drive was brought to Court by Mr Craig McCoy. An IT consultant had been asked to examine it. There were no deleted files and the crown examined it to see if the hard drive had been reset at any time but couldn't find anything to support that idea.
Many insufficient technology caused this case to spend many years without being solved until forensic technology became the key factor in this
CO4507 Digital Forensic Investigation Introduction Nowadays digital devices are everywhere in our life’s helping peoples in many sectors and providing possibilities to them. By pronounce the term “digital devices” the majority of the peoples thinking the computers, smart phones, tablets and the cloud applications. Now the digital devices are important not only in our work environment, or for entertainment and educational reasons, but are important because we can use them as digital evidence. Any kind of technology that processes information can be used in a criminal way vise versa can be used as digital evidence in the court.
Compelling Evidence In today’s society, high-tech gadgets and the media have given the impression the essential necessity for forensic evidence in order to convict. Once in a while, cases like the Laci Peterson murder come along with little forensic evidence but a whole lot of circumstantial evidence and motive. In the following paragraphs, I will discuss the forensic evidence discovered that led to the conviction and death sentencing of Laci’s husband, Scott Peterson.
i. Manage The term manage is used to mean acquiring the necessary contractual vehicle and resources that include financial resources that are used in running forensic labs and programs. It can also be used to mean to coordinate and build internal and external consensus that can be used to develop and manage an organizational digital forensic program. Management also is to establish a digital forensic team, usually, the one that is composed of investigators, IT professionals and incidents handlers to perform digital and network forensics. Management provides adequate workspaces that at minimum take in to account
“The special properties and technical complexity of digital evidence often makes it even more challenging, as courts find it difficult to understand the true nature and value of that evidence (Boddington, 2015)”. It’s not uncommon for innocents to be convicted and guilty people acquitted because of digital evidence (Boddington, 2015). However, other factors can also affect the validity of the evidence, including: failure of the prosecution or a plaintiff to report exculpatory data; evidence taken out of context and misinterpreted; failure to identify relevant evidence; system and application processing errors; and so forth (Boddington, 2015). “There is a perception, largely undeserved, that digital evidence somehow alters the true nature of the original evidence and is therefore unreliable. Presented properly, digital evidence is capable of being of tremendous assistance to the courts (Hak,
With the introduction of new technology in recent years, the government can discreetly capture evidence from electronic files,
John Smith was arrested for burglary and possession of a narcotic drug. There are several things that will occur in the first hour or so of John Smiths arrest. However, the process from arrest to arraignment and furthermore from John Smiths trail to incarceration then eventually his release to parole or probation is complex and interlocking. First, his person will be secured and transported to the police station to be processed.
Shipman, aka Dr. Death, murders are the postmortem examination whose analysis of skeletal muscle would have disclosed a significant quantity of morphine, aka heroin, that caused the victims’ deaths. The forensic document examiner is another forensic examiner employed in the Shipman case. Due to the forged will and location of the typewriter in Shipman’s possession, forensic document examiners were used to analyze the two to make a match. Forensic document examiners analyze typewriters, computers, printers, copy machines, and faxes. The examination results in the Shipman case resulted in individual characteristics displayed.
Computer forensics processes must adhere to standards set by the courtroom that often complicates what could have been a simple data analysis. In court, knowing who connected to the system based on logs is not enough. There must be facts that will support those connection
Student Name: Keshab Rawal Student ID: 77171807 Word Count: Title: The rise of anti-forensics: The rise of anti-forensics: Tables of contents: • Overview • Introduction • History • Categories/Tools of anti-forensics • Conclusion • Future Work Overview: Computer forensics is an active topic of research, with areas of study including wireless forensics, network security and cyber investigations. The goal of the computer forensics is to provide information about how the crime happened, why and who is involved in the crime in any legal proceeding by using the computer forensic tools.
As far back as 2001 when the first “Digital Forensics Workshop” was held and a case for standards was made, considerable progress has been made in ensuring the growth and expansion of the practice of computer forensics. Mason (2003) suggested the need for standards by which digital forensic practitioners ensure that evidences for prosecuting cases in the law courts are valid as more judgments from a growing number of cases were reliant on the use of electronic and digital evidences in proving the cases. XXXX (2005 & 2007) emphasized the dynamic nature of technology and its impact on the digital forensics field. Hence, the need for having early standards in regulating the
