Digital Forensic: An Overview of the Application, Tools, and Future

This presentation provides an overview of digital forensic, including its definition, process, and application areas. It discusses the different branches of digital forensic, such as network forensic and mobile device forensic. The presentation also highlights the pros and cons of digital forensic and introduces commonly used forensic tools like FTK and Volatility. Finally, it explores the future of digital forensic in the context of the growing digital trend.

Digital Forensic

What is Forensic?
 Collection and investigation of valid information which provides accurate evidence to civil
and criminal laws in order to take action against the crime.
 This procedure is followed by the below steps
Thoroughly investigates the case.
Suspect statements
Identify the victims and possible criminal.
Establish the relation between the crime scenario with the criminal

What is Digital Forensic?
 Digital forensic is an application of Forensic Science investigation which
is followed by Digital Devices.
This technique is the process of identification, preservation, extraction
and documentation of useful evidence by variety of digital devices which
includes computers and mobile devices.
Extensive detection process by using advance digital equipment.
Comprehensive Investigation.

Branches of Digital Forensic
Network Forensic
This types of forensic process
is concerned with the
observation and investigation
of computer network, internet
traffic in order to collect
useful evidence against the
crime.
Forensic Data
analysis
This is process of data
analyzing which
investigates the structured
data in order to detect
fraudulent activity.
Database
forensic
This process is opt
for the forensic study
performed in forensic
database and
metadata.
Mobile device
Forensic
This procedure is
conducted by
gathering the
evidence against the
crime by mobile
devices.

Application Area of Digital Forensic.
 Individual case investigation.
 Civil crimes.
 Criminal prosecutors.
 Insurance Company.

Example of Digital Forensic Devices
o Volatility
o EnCase
o MailXaminer
o FTK
o REGA

Pro’s of Digital Forensic
There are several benefits of Digital Forensic present in the field of Forensic Science, those benefits are
listed below:
This procedure helps to eliminate or reduce the sampling risk which is one of the biggest advantage of
digital forensic over external auditor.
Digital forensic procedure provides comprehensive comparison result.
Utilizing the vulnerability of any system in order to analyze their fraudulent by rootkits and Sniffers.
 Proper utilization of virus and worm.
Significant Usage of computers and internet has made this approach quite inexpensive.

Con’s of Digital Forensic
 High chance of getting hacked.
 Due to the dynamic technology changes, there is a significant issue regarding system
upgrade.
 Lack of physical evidence.
 In order to suspect large amount of storage is needed, which is around 10 terabytes.

Mostly Used Forensic Tool
 FTK ( Forensic Toolkit)
This is a digital forensic software application developed by AccessData in 2017.
Data driven image preview and investigation process.
In the field of cybercrime and corporate security the wide use of FTK has been
observed.
 Provides MD5 and SHA1 hashes.

Mostly Used Forensic Tool
 Volatility
This digital forensic tool is created in 2016.
Developed in order to analyze malware.
This tool is developed using Python. Which supports Microsoft, Linux as well as the Mac
OS x.

Future of Digital forensic
As per the growing digital trend the future of Digital forensic is exceptionally good
considering the fact that the process of digital forensic is a speedy and inexpensive process
in the field of forensic investigation. However, Digital forensic has significant benefits
limitations of this cannot be ignored. Thus, the investigator must protect there machines
from hackers and should always keep the system up to dated.
