Before going any further, look at this video in which our cybersecurity specialists explain the nitty-gritty of cybersecurity technology.
What is Cyber Forensics?
The science of collecting, inspecting, interpreting, reporting, and presenting computer-related electronic evidence is known as cyber forensics. Evidence can be found on the hard drive or in deleted files.
It is the process of examining, acquiring, and analyzing data from a system or device so that it can be transcribed into physical documentation and presented in court.
During the inspection, it is critical to create a digital or soft copy of the system’s special storage cell. The purpose of carrying out a detailed cyber forensics investigation is to determine who is to blame for a security breach. The entire inquiry is carried out on the software copy while ensuring that the system is not affected.
In the technological age, cyber forensics is an inevitable factor that is incredibly important.
How are cybersecurity and digital forensics related?
Cybersecurityaims to reduce the risk ofcyberattacks and protect against unauthorized exploitation of systems, networks, and technologies. While digital forensicsfocuses on the recovery and investigation of artifacts found on adigitaldevice.

Cyber Forensics Scope
As everything becomes digitalized, the scope of cyber forensics expands. It assists us in combating hostile actions by identifying underlying perpetrators. The evidence gathered during inquiries aids cybersecurity specialists in locating the hackers and crackers.
The role of cyber forensic experts is becoming much more crucial nowadays due to the increase in cybercrime. According to NCRB, cybercrime has doubled from 2016 to 2018, and it is predicted to increase as much as four times than the present day. This shows the importance of law enforcement in solving cybercrime and cyber experts facing various cyber forensics challenges.
Cyber forensics enables specialists to remotely examine any crime scene by reviewing the browsing history, email records, or digital trace.
The Process Involved in Cyber Forensics
Cyber forensics takes a systematic interpretation, sorting it out concisely.
- Obtaining a digital copy of the under inspection system: This method entails producing a copy of the system’s data to avoid harm from being done to the actual system, which might lead to file confusion with the files already present on the computer. Cloning a hard disc entails replicating the hard drive’s files and folders. The duplicate is present on another disc by copying every small piece of data for analysis.
- Authenticating and confirming the replica: After copying the files, experts verify that the copied data is consistent and exactly as it exists in the real system.
- Determining that the copied data is forensically acceptable: It is possible to change the format of the data while duplicating it from a device, resulting in discrepancies in the operating systems of the investigators and the one from which the data was copied. To avoid this, detectives ensure that the structure stays constant and that the data is forensically acceptable and is written on the hard disk drive in a format that is adequately used in the computer.
- Recovering deleted files: Criminals think of innovative ways of deleting the scene and often remove some data that could indicate their misconduct; it is the work of the investigators to recover and reconstruct deleted files with state-of-the-art software.
Forensics specialists can recover files erased by the user from a computer; the files are not permanently wiped from the computer, and forensics specialists can recover them.

- Finding the necessary data with keywords: Researchers use specific high-speed tools to get appropriate information by employing buzzwords in the instance document.
The OS perceives vacant space in the hard disc as room for storing new files and directories; however, temporary files and documents that were erased years ago will be stored there until new data is entered. Forensics specialists look for these files using this free space.
Forensics specialists utilize tools that can access and produce pertinent information throughout all data for phrases.
- Establishing a technical report: The last phase will be to produce a technical report that is relevant and easily understood regardless of the background of the individual. The result of this report is to state clearly the crime, possible culprits, and innocent individuals.
The technical report must be straightforward for everyone to grasp, irrespective of their background. It should focus mostly on who the culprit is and what techniques they used to commit the crime and how.

Skills Required for a Cyber Forensic Investigator
- Technical Aptitude: Cybersecurity is a technology-driven field; you will probably be responsible for debugging, regularly updating the ISS, and offering protection systems in real-time. To conduct the normal operations of cybersecurity professionals, being technologically competent is necessary.
- Beware of details: To preserve the vital elements of an organization and to avoid risks, you need to be very alert and detailed. You would, most likely, be required to conduct a thorough assessment of your infrastructure, swiftly spot issues, and develop ways to solve them in actual environments.
- Analytical ability: A major part of being a cyber forensics specialist is the capability to analyze and build a clear comprehension of data.
- Strong communication skills: A crime scene investigator must be able, as part of a case, to examine and explain technical facts to others in depth.

Cyber Forensics Tools
Let us take a look at some cyber forensics investigation tools:
- Data capture tools: Data capture tools offer computerized assistance, among other things, for forensic testing, data collecting, reporting, query resolution, randomization, and authentication.
- File viewers: A file viewer is a software that correctly displays the data recorded in a file. In contrast to an editor, only the content of a file is visualized by the file viewer.
- File analysis tools: Software for file analysis are developed to allow cyber expertsto comprehend the file structure of an organization. These technologies index, search, monitor, and evaluate critical file data.
- Internet analysis tools: Google Analytics is one of the best, freetoolthat any website owner can use to track andanalyzedata aboutwebtraffic.
Cyber Forensic Career Path
Cyberattacks are growing regularly, and to address them, cyber forensics is required. Cyberterrorism not only threatens an organization but also harms the lives of people through the online promotion of narcotics, militancy, etc. Therefore, it is crucial that cybercrimes are dealt with. There are ample job opportunities in the field of cybersecurity in India as well as around the globe.
According to PayScale, salaries in the field of cyber forensics in India range from INR four lakh per annum to INR eight lakh per annum.
The science of collecting, inspecting, interpreting, reporting, and presenting computer-related electronic evidence is known as cyber forensics. It assists us in combating hostile actions by identifying the underlying perpetrators. Cyberattacks are ever-growing, and cyber forensics is required to address such activities.
