Data acquisition formats

  • What are the formats of data acquisition in digital forensics?

    The four methods of acquiring data for forensics analysis are disk- to- image file, disk-to- disk copy, logical disk- to- disk or disk- to- data file, or sparse data copy of a folder or file.
    Large disks might require using tape backup devices..

  • What format is forensic data acquisition?

    Forensics data acquisitions are stored in three different formats: raw, proprietary, and AFF..

  • Raw format: This is the oldest version of data format that has been used.
    It mainly makes a duplicate copy of the disk by performing bit by bit copying from one disk to another.

Creating a disk-to-disk copy 3.
Creating a logical disk-to-disk or disk-to-data file 4.
Creating a sparse copy of a folder or file.

What are the disadvantages of proprietary format acquisitions?

Proprietary Formats - One major disadvantage of proprietary format acquisitions is the inability to share an image between different vendors’ computer forensics analysis tools.
If your time is limited, consider using a logical acquisition or sparse acquisition data copy method.

The CALS Raster file format is a standard for the interchange of graphics data.
It was developed by the United States Department of Defense (DoD) as part of the Continuous Acquisition and Life-cycle Support (CALS) initiative.
It defines a standard storing raster (bit-mapped) image data, either uncompressed or compressed using CCITT Group 4 compression.
