What Is Digital Forensics?
Digital forensic science is a branch of forensic science that focuses on the recovery and investigation of material found in digital devices related to cybercrime. The term digital forensics was first used as a synonym for computer forensics. Since then, it has expanded to cover the investigation of any devices that can store digital data. Although the first computer crime was reported in 1978, followed by the Florida computers act, it wasn’t until the 1990s that it became a recognized term. It was only in the early 21st century that national policies on digital forensics emerged.
Digital forensics is the process of identifying, preserving, analyzing, and documenting digital evidence. This is done in order to present evidence in a court of law when required.

Next, isolate, secure, and preserve the data. This includes preventing people from possibly tampering with the evidence.

Who Is a Digital Forensics Investigator?
A Digital Forensics Investigator is someone who has a desire to follow the evidence and solve a crime virtually. Imagine a security breach happens at a company, resulting in stolen data. In this situation, a computer forensic analyst would come in and determine how attackers gained access to the network, where they traversed the network, and what they did on the network, whether they took information or planted malware. Under those circumstances, a digital forensic investigator’s role is to recover data like documents, photos, and emails from computer hard drives and other data storage devices, such as zip and flash drives, with deleted, damaged, or otherwise manipulated.

How Is Digital Forensics Used in an Investigation?
Digital footprint is the information about a person on the system, such as the webpages they have visited, when they were active, and what device they were using. By following the digital footprints, the investigator will retrieve the data critical to solving the crime case. To name a few –Matt Baker, in 2010, Krenar Lusha, in 2009, and more cases were solved with the help of digital forensics.
Cyber forensic investigators are experts in investigating encrypted data using various types of software and tools. There are many upcoming techniques that investigators use depending on the type of cybercrime they are dealing with. Cyber investigators’ tasks include recovering deleted files, cracking passwords, and finding the source of the security breach. Once collected, the evidence is then stored and translated to make it presentable before the court of law or for police to examine further. The role of cyber forensics in criminal offenses can be understood with a case study: cold cases and cyber forensics
Recent Case Study –
Thousands of digital devices that have been seized by police as evidence for alleged crimes, including terrorism and sexual offenses, are sitting in storage in a growing backlog that investigators are struggling to tackle.
In the lack of efficient resources to analyze the evidence, the PA news agency has found that 12,122 devices (includes phones, tablets, and computers) are awaiting examination across 32 forces. Unlikely, the backlog has remained the same previous year resulting in hampering prosecutors in criminal cases. In another case, a Times investigation from the last year confirmed awaiting examination of 12,667 devices from 33 police forces. The long-pending investigations show how overwhelmed a digital forensic team is due to the sheer volume of digital evidence collected.
Phases of Digital Forensics
What Are Digital Forensics Tools?
The Sleuth Kit
The Sleuth Kit (earlier known as TSK) is a collection of Unix- and Windows-based utilities that extract data from computer systems. It is an open-source software that analyzes disk images created by “dd” and recovers data from them. With this software, professionals can gather data during incident response or from live systems. Professionals can integrate TSK with more extensive forensics tools.
FTK Imager is an acquisition and imaging tool responsible for data preview that allows the user to assess the device in question quickly. The tool can also create forensic images (copies) of the device without damaging the original evidence.
Xplico is a network forensic analysis tool (NFAT) that helps reconstruct the data acquired using other packet sniffing tools like Wireshark. It is free and open-source software that uses Port Independent Protocol Identification (PIPI) to recognize network protocols. The tool is built on four key components: Decoder Manager, IP Decoder, Data Manipulators, and Visualization System.

Digital Forensics Job Profiles
If you have good analytical skills, you can forge a successful career as a forensic
computer analyst, tracing the steps of cybercrime
The role of a forensic computer analyst is to investigate criminal incidents and data breaches. These forensic analysts often work for the police, law enforcement agencies, government, private, or other forensic companies. They use specialized tools and techniques to retrieve, analyze, and store data linked to criminal activity like a breach, fraud, network intrusions, illegal usage, unauthorized access, or terrorist communication.

The Life of a Digital Forensic Investigator
Challenges a Computer Forensic Analyst Faces
The most notable challenge digital forensic investigators face today is the cloud environment. While cloud computing is incredibly beneficial to an organization, they are also challenging for forensics investigators. The basic principle that the cloud is somebody else’s computer holds some truth, but huge server farms host most data. Since the cloud is scalable, information can be hosted in different locations, even in different countries. This makes it extremely difficult to gather accurate and trusted evidence in a case because establishing a proper chain of custody becomes nearly impossible. In addition, the jurisdiction of the data must be considered since different laws apply to depend on where it is located.
