Digital forensics is a branch of the
forensic sciences related to the investigation of digital devices and
media. Within the field a number of "normal" forensics words are re-purposed, and new specialist terms have evolved.
A
Acquisition
The process of creating a duplicate copy of
digital media for the purposes of examining it[1]
C
Computational forensics
Computational forensics are digital forensics with the use of artificial intelligence.
D
Digital media
Used within the fields to refer to the physical medium (such as a hard drive) or
data storage device
Analysis of a piece of digital media from within itself; often used to acquire data from RAM where this would be lost upon shutting down the device[2]
S
Slack space
The unused space at the end of a file in a file system that uses fixed size clusters (so if the file is smaller than the fixed block size then the unused space is simply left). Often contains deleted information from previous uses of the block
Steganography
The word
steganography comes from the Greek name “steganos” (hidden or secret) and “graphy” (writing or drawing) and literally means hidden writing. Steganography uses techniques to communicate information in a way that is
hidden.[4]
