Forensic Data Acquisition. DATA ACQUISITION. Data acquisition is the process of making a forensic image from computer media such as a hard drive, thumb drive, CDROM, removable hard drives, thumb drives, servers and other media that stores electronic data including gaming consoles and other devices.
What is evidence acquisition?
Evidence acquisition is concerned with the collection of evidence from digital devices for subsequent analysis and presentation. … This is done in the context of the Reco Platform, an open source forensic framework that was used to develop the prototype evidence acquisition tool both quickly and efficiently.
Why data acquisition is important in digital forensics?
Courts take a careful notice of the way in which digital evidence has been acquired and stored. … A standardised data acquisition process model is needed to enable digital forensic investigators to follow a uniform approach, and to assist courts of law in determining the reliability of digital evidence presented to them.
What is acquisition in cyber forensics?
What is acquisition in digital forensics? … It involves producing a forensic image from digital devices including CD ROM, hard drive, removable hard drives, smartphones, thumb drive, gaming console, servers, and other computer technologies that can store electronic data.
What is image acquisition in cyber forensics?
Image acquisition of the materials from the crime scene by using the proper hardware and software tools makes the obtained data legal evidence. … As for software tools, they provide usage of certain write-protect hardware tools or acquisition of the disks that are directly linked to a computer.
What evidence does forensic acquisition acknowledge?
The essence of this acquisition type is to minimise impacts to the integrity of the system while capturing volatile forensic data (McDougal 2006:5,9). Live Acquisition refers to the acquisition of a machine that is still running and can retrieve both static and dynamic, volatile data (Forte 2008:13).
What are the steps involved in evidence acquisition?
There are four phases involved in the initial handling of digital evidence: identification, collection, acquisition, and preservation ( ISO/IEC 27037 ; see Cybercrime Module 4 on Introduction to Digital Forensics).
What is the process of network forensic?
The process of capture, recording, and analysis of network packets to determine the source of network security attacks is known as Network Forensics. … Network Forensics examinations have seven steps including Identification, Preservation, Collection, Examination, Analysis, and Presentation and Incident Response.
What is a logical acquisition?
The logical acquisition is a bit-by-bit copy of a given logical storage, (the storage may refer to user data partition as well as system data partition), and this acquisition method produces, in general, a relatively manageable file which can be analyzed and parsed by forensic tools.
What are data acquisition systems?
A data acquisition system is a collection of software and hardware that allows one to measure or control physical characteristics of something in the real world. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software.
What is a sparse acquisition?
sparse acquisition. Like logical acquisitions, this data acquisition method captures only specific files of interest to the case, but it also collects fragments of unallocated (deleted) data. See also logical acquisition.
What is disk to image file acquisition?
It is a flexible method, which allows creation of one or more copies, or bit-for-bit repkations of the suspect drive. ProDiscover, EnCase, FTK, The Sleuth Kit, X-Ways Forensics, ILook Investigator, etc. are the popular tools used to read the disk-to-image files.
What is a dead box computer?
Since investigators typically “pull the plug” on the computer system prior to acquiring an exact copy of the hard drive, this particular methodology is referred to as dead-box forensics—a technique that analyzes the data at rest. … There is also this point to consider: RAM contains data that is not found on the disk.
What is Live digital forensics?
ABSTRACT: Live forensics is a sprouting branch of digital forensics that performs the forensics analysis on. active system; Active systems are normally running systems. Live forensics provides accurate and consistent data for investigation compared to incomplete data provided by traditional digital forensics process.
What’s the difference between live and forensics mode?
There is a feature of “Kali Linux Live” that provides a ‘Forensic Mode’ for its users. The ‘Forensics mode’ is equipped with tools made for the explicit purpose of digital forensics. Kali Linux ‘Live’ provides a Forensic mode where you can just plug in a USB containing a Kali ISO.
What is Live Analysis digital forensics?
Traditional digital forensics is performed through static analysis of data preserved on permanent storage media. … Live analysis uses running system to obtain volatile data for deeper understanding of events going on. Sampling running system might irreversibly change its state making collected evidence invalid.
