Understanding Different Types of Digital Forensics Exercised

Many people might think that computer and digital forensics are two sides of the same coin. But little do they realize that the former is a part of the latter. And like computer forensics, there are many types of digital forensics which are evolving constantly in the scientific field with various sub-disciplines. Some of these sub-divisions are listed below.

  1. Computer forensics

Computer forensics involves identifying, preserving, soliciting, analysing, and reporting the proof found on the computer systems, laptops and storage media relevant to the investigation and legal proceedings.

  1. Network forensics

Network forensics involves monitoring, capturing, preserving, and analysing the network events to locate the source of the security attacks, breaches or other events like virus, worms, malware attacks, security breaches and unusual network traffic.

  1. Mobile phone forensics

Mobile phone forensics involves recovering the electronic proof from cell phones, SIM cards, smart phones, GPS devices, PDAs, tablets and game consoles.

  1. Digital image forensics

Digital image forensics involves extracting and analysing the digitally gained photographic evidence to verify its authenticity by the recovery of the metadata of the image to determine its history.

  1. Digital audio or video forensics

Digital audio or video analysis involves collecting, analysing, and evaluating the audio and video recordings. It is the means to authenticate the originality of these files or whether it has been tampered either accidentally or maliciously.

  1. Memory forensics

Memory forensics involves recovering the evidence from RAM of a computer system which is called known as live acquisition.

When digital forensics is put into practice, there are still exceptions looming behind the stage to blur away this classification because this grouping is implemented on the basis of skill sets, lab space, contractual requirements etc. For instance:

  1. Smartphones are operable without SIM cards and can be deemed as computers.
  2. Removable media devices like memory cards are also a part of mobile forensics or computer forensics.
  3. Tablets with in-built keyboards can also be deemed as laptops and classified under computer or mobile forensics.

The universe of digital forensics at companies like Elijaht will consistently evolve with endless future and more advanced technologies and it will continue to bloom with innovative kinds of digital data built by new devices which is capable to log into the activities of the people. Even though, digital forensics is initiated outside the mainstream of forensics, it is now completely and totally deemed as a branch of forensic science.
