1.What is Digital Forensics?

Digital Forensics is outlined because the method of preservation, identification, extraction, and documentation of pc proof which might be utilized by the court of law. it’s a science of finding proof from digital media sort of a pc, movable, server, or network. It provides the rhetorical team with the simplest techniques and tools to resolve sophisticated digital-related cases.
Digital Forensics helps the rhetorical team to analyzes, inspect, identifies, and preserve the digital proof residing on numerous styles of electronic devices.

2.History of Digital forensics

Here, are vital landmarks from the history of Digital Forensics:
  • Hans Gross (1847 -1915): initial use of scientific study to go criminal investigations
  • FBI (1932): came upon a work to supply forensics services to all or any field agents and alternative law authorities across the USA.
  • In 1978 the primary pc crime was recognized within the Sunshine State pc Crime Act.
  • Francis man of science (1982 – 1911): Conducted initial recorded study of fingerprints
  • In 1992, the term pc Forensics was employed in tutorial literature.
  • 1995 international organisation on pc proof (IOCE) was fashioned.
  • In 2000, the primary Federal Bureau of Investigation Regional pc rhetorical Laboratory established.
  • In 2002, Scientific Working Group on Digital Evidence (SWGDE) published the first book about digital forensic called “Best practices for Computer Forensics”.
  • In 2010, Simson Garfinkel known problems facing digital investigations.

3.Objectives of pc forensics

Here are the essential objectives of victimisation pc forensics:
  • It helps to recover, analyze, and preserve pc and connected materials in such a way that it helps the investigation agency to gift them as proof in an exceedingly court of law.
  • It helps to postulate the motive behind the crime and identity of the most perpetrator.
  • Designing procedures at a suspected crime scene that helps you to make sure that the digital proof obtained isn’t corrupted.
  • Data acquisition and duplication: ill deleted files and deleted partitions from digital media to extract the proof and validate them.
  • Helps you to spot the proof quickly, and conjointly permits you to estimate the potential impact of the malicious activity on the victim
  • Producing a pc rhetorical report that offers an entire report on the investigation method.
  • Preserving the proof by following the chain of custody.

4.Process of Digital forensics

Digital forensics entails the following steps:
  • Identification
  • Preservation
  • Analysis
  • Documentation
  • Presentation
What is Digital Forensics? History, Process, Types, Challenges



Let’s study each in detail



It is the first step in the forensic process. The identification method primarily includes things like what proof is gift, wherever it’s keep, and lastly, however it’s keep (in that format).
Electronic storage media will be personal computers, Mobile phones, PDAs, etc.


In this part, information is isolated, secured, and preserved. It includes preventing individuals from victimisation the digital device in order that digital proof isn’t tampered with.


In this step, investigation agents reconstruct fragments of information and draw conclusions supported proof found. However, it would take various iterations of examination to support a selected crime theory.


In this method, a record of all the visible information should be created. It helps in recreating the crime scene and reviewing it. It Involves correct documentation of the crime scene together with photographing, sketching, and crime-scene mapping.


In this last step, the method of summarisation and rationalization of conclusions is completed.
However, it should be written in a layperson’s terms using abstracted terminologies. All abstracted terminologies ought to reference the particular details.

5.Types of Digital Forensics

Three styles of digital forensics are:

Disk Forensics:

It deals with extracting information from storage media by looking out active, modified, or deleted files.

Network Forensics:

It may be a sub-branch of digital forensics. it’s regarding observation and analysis of electronic network traffic to gather vital data and legal proof.

Wireless Forensics:

It may be a division of network forensics. the most aim of wireless forensics is to offers the tools got to collect and analyze the information from wireless network traffic.

Database Forensics:

It may be a branch of digital forensics regarding the study and examination of databases and their connected data.

Malware Forensics:

This branch deals with the identification of malicious code, to check their payload, viruses, worms, etc.

Email Forensics :

Deals with recovery and analysis of emails, as well as deleted emails, calendars, and contacts.

Memory Forensics:

It deals with aggregation information from system memory (system registers, cache, RAM) in raw kind so carving the information from Raw dump.

Mobile Phone Forensics:

It primarily deals with the examination and analysis of mobile devices. It helps to retrieve phone and SIM contacts, call logs, incoming, and outgoing SMS/MMS, Audio, videos, etc.

6.Challenges long-faced by Digital Forensics

Here, are major challenges faced by the Digital Forensic:
  • The increase of PC’s and extensive use of internet access
  • Easy availability of hacking tools
  • Lack of physical evidence makes prosecution difficult.
  • The great amount of space for storing into Terabytes that produces this investigation job tough.
  • Any technological changes need associate degree upgrade or changes to solutions.

7.Example Uses of Digital Forensics

In recent time, industrial organizations have used digital forensics in following a sort of cases:
  • Intellectual Property theft
  • Industrial espionage
  • Employment disputes
  • Fraud investigations
  • Inappropriate use of the web and email within the workplace
  • Forgeries connected matters
  • Bankruptcy investigations
  • Issues concern with the regulative compliance

8.Advantages of Digital forensics

Here, are pros/benefits of Digital forensics
  • To make sure the integrity of the pc system.
  • To manufacture proof within the court, which might result in the penalization of the perpetrator.
  • It helps the businesses to capture vital data if their pc systems or networks are compromised.
  • Efficiently tracks down cybercriminals from anyplace within the world.
  • Helps to protect the organization’s money and valuable time.
  • Allows to extract, process, and interpret the factual proof, so it proves the cybercriminal action’s in the court.

9.Disadvantages of Digital Forensics

Here, are major cos/ drawbacks of victimisation Digital Forensic
  • Digital proof accepted into court. However, it’s should be proven that there’s no tampering
  • Producing electronic records and storing them is a very expensive affair
  • Legal practitioners must have intensive pc knowledge
  • Need to provide authentic and convincing evidence
  • If the tool used for digital rhetorical isn’t in line with nominative standards, then within the court of law, the proof will be marginal by justice.
  • Lack of technical information by the investigation officer won’t supply the required result .


Hope you’ll perceive this post , you need to conjointly realize this subject . Moral Hacking ( half – vi ) is completed . In next half we have a tendency to are about to find out how to hack an online server (In sight of Education ) . conjointly raise your doubt within the comments .
