The Role of Digital Forensics in Combating Cybercrimes

Through this article, we’ll gain an in-depth knowledge as to why cyber forensics technology is crucial and important in solving cyber or digital crimes. Basically, cyber forensics is a method through which cyber forensic experts can obtain data as evidence of a cybercriminal who have committed any major cyber crime through using an electronic equipment. The team of forensic experts should have to comply with correct investigative procedures by submitting electronic or digital evidence on the basis of which it can assist the courts to make correct judgements.

What makes Cyber Forensics so important in solving digital cybercrimes?

• The technology of cyber forensics plays a massive role in today’s highly advanced and modern generation. Faster investigation process with precise outcomes is the major objective for every cyber forensic expert using cyber forensics technology.

• Cyber forensics assists cyber forensic experts in gathering crucial electronic proof or digital evidence in order to track down the offender who have committed any criminal offence.

• The evidence gathered digitally can also be used by people with no guilt to prove their innocence through cyber forensics technology.

• Real-world crimes like burglary, murder, theft, and other crimes can be also solved using cyber forensics technology in addition to using it to solve digital crimes.

• When it comes to monitoring data breaches and identifying the attackers, business organizations can also gain profit from cyber forensics technology.

What procedure do Cyber Forensic experts follow while doing investigation?

1)Data Recognition – Cyber forensic experts have to first figure out what kind of proof is available, what location it has been kept, as well as the form that it is kept.

2) Data Maintenance – After figuring out the data, the next step is to carefully maintain the data and not allowing other individuals to access the gathered evidence so that no one is able to manipulate with it.

3) Data Analysis – This procedure then moves on to system or data analysis. The cyber forensic experts finds the evidence that the cybercriminal tried to destroy. Here the cyber forensic expert retrieves the deleted files and analyse the data in order to find the evidence that the cybercriminal attempted to remove by deleting the files which have been kept in a secret location.

4) Data Documentation – After data analysis, the information has been provided. The file in question contains all of the retrieved and readily accessible (not destroyed) data that is useful for evaluating and reconstructing the crime scene.

5) Displaying Information – At last, the information that has been analyzed is finally provided to the court to help them in making correct decisions or judgements.

Which methods are employed by Cyber Forensic experts while doing investigation?

1) Reverse Steganography – It is a method for concealing crucial information inside of a digital file, image, etc. Therefore, reverse steganography is used by cyber forensic specialists to analyse the data and discover a connection to the case.

2) Stochastic Forensics – In this method, forensic experts examine and recreate online activities using this technique without the help of digital artefacts. In this context, the term “artefacts” refers to unexpected data changes brought on by digital processes.

3) Cross-drive Analysis – In this method, data from various computer discs is correlated and cross-referenced in order to preserve and examine data that is pertinent to the investigation.

4) Live Analysis – With this method, the operating system on the of the culprit’s computer is examined in order to obtain some useful information.

What are the different categories of Cyber Forensics?

1) Network Forensics – In this category of cyber forensics, the experts keep an eye on the network traffic going to and coming from the criminal’s network using automated network intrusion detection systems.

2) Email Forensics – In this category of cyber forensics, the experts examine the cybercriminal’s email and retrieve deleted email conversations to gather important case-related information.

3) Malware Forensics – In this category of cyber forensics, the experts carefully examine at the malware and trojans in order to identify who the involved hacker.

4) Memory Forensics – In this category of cyber forensics, the experts gather raw data from the hacker’s system memory, such as cache and RAM, and then extract information from that data.

5) Mobile Forensics – In this category of cyber forensics, the experts carefully look over and assess the hacker’s retrieved mobile phone details.

6) Database Forensics – In this category of cyber forensics, the experts assess and evaluate the data retrieved from hacker’s database and their linked information.

7) Disk Forensics – In this category of cyber forensics, the forensics expert extracts data from storage media by scanning modified, active, or deleted files.

The Conclusion

Hence, from the above discussion, we can conclude this article by saying that cyber forensics guarantees the system’s security. Cyber forensics collect evidence from digital devices and offer it to the court so that the offender may be punished. Many people, businesses, and other entities learn about these crimes thanks to cyber forensics, and they then take the necessary precautions to prevent them.
