What is 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.

Similarly, it is asked, 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.

Subsequently, question is, what is data acquisition in cyber forensics? 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.

In this manner, 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 the main goal of static acquisition?

The main goal of a static acquisition is the preservation of digital evidence.

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 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.

18. What is a hashing algorithm?	A program designed to create a binary or hexadecimal number that represents the uniqueness of a data set, file, or entire disk

What is physical acquisition?

A physical acquisition captures all of the data on a physical piece of storage media. This is a bit-for-bit copy, like the clone of a hard drive. This acquisition method captures the deleted information as well. In contrast, a logical acquisition captures only the files and folders without any of the deleted data.

How can data acquisition be performed on an encrypted drive?

Data acquisition can be performed on an encrypted drive by using the key to perform the decryption leading to data access easily.

Why is forensic acquisition important?

Live forensic acquisition provides for digital evidence collection in the order that acknowledges the volatility of the evidence and collects it in the order of volatility to maximize the preservation of evidence.

Can a live acquisition be replicated?

A live acquisition can be replicated.

What does an autopsy validate an image?

Image Integrity: Being that one of the most crucial aspects of a forensics investigation involves ensuring that data is not modified during analysis; Autopsy will generate an MD5 value for all files that are imported or created by default. The integrity of any file that Autopsy uses can be validated at any time.

What is live analysis?

Live analysis. The examination of computers from within the operating system using custom forensics or existing sysadmin tools to extract evidence.

What is live system forensics?

Live data forensics is one part of computer forensics which is a branch of digital forensic science pertaining to legal evidence found in computers. Live data forensics follows this aim but is only focused on computer systems that are powered on.

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 are the types of digital evidence?

Different types of Digital Forensics are Disk Forensics, Network Forensics, Wireless Forensics, Database Forensics, Malware Forensics, Email Forensics, Memory Forensics, etc.

How does a forensics examiner define an acquisition?

Acquisition: Acquisition is the process of collecting digital evidence from an electronic media. There are four methods for acquiring data: disk-to-disk copy, disk-to-image file, logical disk-to-disk file, and sparse data copy of a file or folder.

What are the three minimum steps of a basic digital forensics examination protocol?

Forensics researcher Eoghan Casey defines it as a number of steps from the original incident alert through to reporting of findings. The process is predominantly used in computer and mobile forensic investigations and consists of three steps: acquisition, analysis and reporting.

How do you collect digital evidence?

Digital evidence is typically handled in one of two ways:

The investigators seize and maintain the original evidence (i.e., the disk). This is the typical practice of law enforcement organizations.
The original evidence is not seized, and access to collect evidence is available only for a limited duration.

What is the difference between digital forensics and computer forensics?

Computer Forensics specifically means the Computing Devices. While Digital Forensics Means all the Devices that works on 0 and 1 it includes Mobile Phones, PDA's, Smart Watches, Printers, Scanners, Secondary Storage Media, Bio metric Devices.

What data does digital forensics use?

Digital forensics is a branch of forensic science focused on recovery and investigation of artifacts found on digital devices. Any devices that store data (e.g. computers, laptops, smartphones, thumb drives, memory cards or external hard drives) are within the ambit of digital forensics.
