What is data acquisition in computer forensics?
DATA ACQUISITION. Data acquisition refers to the creation of a forensic image using computer media, such as thumb drives, CDROMs, thumb drives and removable hard drives.
You might also wonder, "What is acquisition computer forensics?"
Acquisition: Digital evidence is collected from electronic media. There are four ways to acquire data. These include disk-to disk copy, disk-to–image file, logical disc-to–disk file and sparse copy of a folder or file. For court proceedings, only well-preserved evidence is admissible.
What is evidence acquisition? Acquisition refers to the process of copying and cloning digital evidence from mobile devices. FTK imager, Oxygen forensic Suite, Windows Mobile Devices, Zune and X-Ways can all be used to imaging.
Why is forensic acquisition so important?
Forensic acquisition allows for digital evidence to be collected in an order that recognizes the variability of the evidence. This ensures maximum preservation.
What is the difference in digital forensics from computer forensics?
Computer Forensics refers to the Computing Devices. Digital Forensics refers to all devices that work on 0 or 1. It includes mobile phones, smart watches, printers, scanners, secondary storage media, biometric devices, and Smart Watches.

What is a forensic image?
A forensic image is an image or exact, sector by sector, copy of a hard disk, taken using software such as Paraben Lockdown/Forensic Replicator or Logicube Forensic Dossier.
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's the main goal of a static acquisition?
What is the primary goal of static acquisition? to preserve the digital evidence.
Why is the area of computer forensics important?
Computer forensics is also important because it can save your organization money. From a technical standpoint, the main goal of computer forensics is to identify, collect, preserve, and analyze data in a way that preserves the integrity of the evidence collected so it can be used effectively in a legal case.
What is digital evidence and its types?
Digital evidence can be any sort of digital file from an electronic source. This includes email, text messages, instant messages, files and documents extracted from hard drives, electronic financial transactions, audio files, video files.
What is live acquisition?
A "live" acquisition is where data is retrieved from a digital device directly via its normal interface; for example, switching a computer on and running programs from within the operating system.
What is digital forensics used for?
As well as identifying direct evidence of a crime, digital forensics can be used to attribute evidence to specific suspects, confirm alibis or statements, determine intent, identify sources (for example, in copyright cases), or authenticate documents.
What is the difference between static acquisitions and live acquisitions?
Static Acquisition: which is the preferred way to collect a digital evidence when a computer seized during police raid. Live Acquisition: is the way to collect digital evidence when a computer is powered on and the suspect has been logged on to. This type is preferred when the hard disk is encrypted with a password.
What are the steps involved in forensic analysis?
The digital forensic process is a recognized scientific and forensic process used in digital forensics investigations. The process is predominantly used in computer and mobile forensic investigations and consists of three steps: acquisition, analysis and reporting.
What are the steps of forensic analysis?
What Are the Steps in Forensic Analysis?
- 1) Seizure.
- 2) Acquisition.
- 3) Analysis.
- 4) Reporting.
- Visual Inspection: The purpose of this inspection is just to determine the type of evidence, its condition, and relevant information to conduct the examination.
What is a forensic analysis report?
Forensic analysis refers to a detailed investigation for detecting and documenting the course, reasons, culprits, and consequences of a security incident or violation of rules of the organization or state laws. Forensic analysis is often linked with evidence to the court, particularly in criminal matters.
What is the first step in the development of computer forensic capabilities?
The first digital forensic process model proposed contains four steps: Acquisition, Identification, Evaluation and Admission. Since then, numerous process models have been proposed to explain the steps of identifying, acquiring, analysing, storage, and reporting on the evidence obtained from various digital devices.
What is static acquisition?
static acquisition. a data acquisition method used when a suspect drive is write-protected and can't be altered. if disk evidence is preserved correctly, static acquisitions are repeatable. whole disk encryption. an encryption technique that performs a sector-by-sector encryption of an entire drive.
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.
How long does a forensic computer analysis take?
A complete examination of a 100 GB of data on a hard drive can have over 10,000,000 pages of electronic information and may take between 15 to 35 hours or more to examine, depending on the size and types of media.
What is digital forensics and how is it used in investigations?
Digital Forensics revolves around investigation of digital data collected from the multiple digital sources. The collected data is preserved and analyzed by cyber crime investigator. Further, it can then be used as a potential source of evidence in the court of law.
When did digital forensics start?
Until the late 1990s, what became known as digital forensics was commonly termed 'computer forensics'. The first computer forensic technicians were law enforcement officers who were also computer hobbyists. In the USA in 1984 work began in the FBI Computer Analysis and Response Team (CART).
