Is Advanced Forensic Format a proprietary format?
Abstract This paper describes the Advanced Forensic Format (AFF), which is designed as an alternative to current proprietary disk image formats. AFF offers two significant benefits. … Raw images are widely used because they work with practically every forensic tool available today.
What is a proprietary file?
(ii) A proprietary file format is one that a company owns and controls. Data in this format may need proprietary software to be read reliably. … Proprietary software usually reads and saves data in its own proprietary format. For example, different versions of Microsoft Excel use the proprietary XLS and XLSX formats.
What is raw format in digital forensics?
The RAW image format is basically a bit-for-bit copy of the RAW data of either the disk or the volume stored in a single or multiple files. There is no metadata stored in the image files. … This means almost every tool supports raw images. Even non-forensic tools.
Which format does not support compression in cyber forensics?
A new file format, Advance Forensics Format (AFF), has been developed to store raw images, which are quite large and cannot be compressed.
What is AFF4?
The advanced forensics file format (AFF4) is a third generation forensic file format integrating multiple image streams, the expression of arbitrary information and storage virtualisation into the forensic file format itself.”
What should be the very first consideration when responding to a crime scene?
Upon entry to the scene, the forensic team must first determine the location of all potential digital crime scenes. At this point, they touch nothing, being careful to not disturb the evidence in its state and only assessing the evidence and what immediate preservation procedures must be performed.

What are the disadvantages of creating a bit stream copy from a disk to a network drive?
The biggest disadvantage is the time involved in transferring the data in bit-stream mode. Typically, only files are used by the operating system or user, but a bit-stream copy will transfer even the unused bits, multiplying the amount of time required to complete the process.
