The Evolution of Computer Forensics: A Historical Perspective

What is Forensic Computing? - LogsignModern society relies heavily on technology, and digital devices are an integral part of our daily lives. However, with the increase in cybercrime, the need for digital forensics also rises. Digital forensics involves gathering and analyzing digital evidence to solve crimes that involve digital devices. Forensic computing is one aspect of digital forensics that deals with the analysis of digital evidence using specialized tools and techniques. In this article, we will provide a comprehensive guide to forensic computers, including what it is, its importance, and the tools and techniques used.


What is forensic computing?

Forensic computing is the practice of analyzing digital evidence from computers, mobile devices, and other digital devices, to uncover potential evidence for a crime or incident, for example, cyber-attacks, data breaches, fraud, and hacking. The process involves recovering deleted files, analyzing network traffic, reviewing log files, and other techniques to extract evidence from digital devices. Forensic computing is crucial in solving crimes with a digital component. It provides the necessary tools and techniques to recover and analyze digital evidence to help investigators and law enforcement agencies to solve crimes and bring to justice those responsible.


The Importance of Forensic Computing

Forensic computing plays a vital role in solving cybercrime cases that involve computers and other digital devices. Cybercrime is on the rise, and the most common forms of cyber attacks include phishing, ransomware, and malware. With forensic computing, investigators can analyze the digital evidence left behind by cybercriminals and track their activities to bring them to justice. It’s worth noting that forensic computing is not only limited to cybercrime investigations but can also be beneficial in business fraud investigations, computer misuse, and intellectual property theft. Forensic computing has gained significant importance in recent years, and it’s no longer an afterthought but a crucial part of digital investigation and evidence gathering.


Tools and Techniques Used in Forensic Computing

Forensic computing relies on various tools and techniques to analyze digital evidence. The tools help to recover information that has been deleted or hidden on digital devices. Here are some of the common tools and techniques used in forensic computing:


Disk Imaging: This is the process of creating a forensic image of a device’s storage media to extract data. Forensic investigators usually use specialized tools like FTK Imager, dd, and EnCase to create disk images.


File Recovery: The process of recovering deleted files from digital devices using specialized tools like Recuva and FTK Imager.


Network Analysis: Network forensics involves analyzing network traffic to extract digital evidence about cyber-attacks. Specialized tools like Wireshark, Snort, and NetworkMiner are used to analyze network data.


Hashing: A technique used to verify data integrity, ensuring that the data has not been modified or corrupted. Hashing tools like HashCalc and Md5sum are used to create digital signatures of data.


The Forensic Computing Process

The forensic computing process involves various stages, including identification, preservation, collection, examination, and reporting. Here is a brief overview of the forensic computing process:


Identification: The initial phase involves identifying digital evidence from the crime scene, such as computers, mobile devices, and other digital devices.


Preservation: Once identified, digital evidence must be properly preserved and secured to ensure that it’s not tampered with or destroyed.


Collection: Once the evidence is preserved and secured, the investigating team will collect the evidence, including disk images, network traffic logs, and any other relevant evidence.


Examination: In this stage, the forensic team will perform a detailed analysis of the digital evidence using various tools and techniques.


Reporting: After completing the examination, the forensic team will prepare a report that details the evidence collected and their findings.




Forensic computing is an important aspect of digital forensics that involves analyzing digital evidence to solve crimes and incidents that involve digital devices. It’s a rapidly growing field that’s gaining significant importance in recent years, as the need for digital investigation and evidence gathering increases. Using specialized tools and techniques, forensic computing can recover deleted files, analyze network traffic, and create disk images to extract digital evidence that can be used in legal proceedings. We hope that this guide provides a comprehensive overview of forensic computing and its importance in the digital age.
