Digital Forensics
Digital Forensics is the process of preserving, obtaining, analyzing, and presenting electronic data so that it can be used as evidence. It is a branch of forensic science that focuses on retrieving and analyzing data from digital devices including computers, and other digital storage media. Digital Forensics’ goal is to determine the details of a digital incident, such as a Cybercrime or data security breach, in a manner that is impartial, thorough, and compatible with legal rules and regulations.
Digital Forensics Process
Digital Forensics involves several processes that are used to investigate and analyze digital devices and systems for evidence in a criminal or civil case. These processes must be conducted in a manner that is compatible with the rules of evidence, and ensures that the evidence can be used in any legal requirements.
The first step in a Digital Forensics process is to start the investigation and seize the evidence. This involves acquiring digital devices or data that is relevant to the case. This may involve seizing electronic devices, such as computers or smartphones, or acquiring data from cloud services.
During this process, the relevant data related to the case is identified and extracted from the collected evidence. This includes information such as emails, documents, images, and other types of digital files that are relevant to the case.
The next step is to collect the evidence from the digital device or system. This may involve using specialized tools and techniques to extract data from the device, such as acquiring a disk image or copying specific files.
Preserving the evidence is the next step here. This involves duplicating the digital data and ensuring that the original data is kept undamaged. This is an important process since it ensures that the evidence will be accepted in court and can be used to support the findings of the investigation.
The collected evidence till now, is then analyzed to uncover any related information. This involves using various Digital Forensics tools to examine the data, such as disk imaging tools, data recovery tools, and many more.
The final step of the Digital Forensics process is to prepare a report, document the findings of the Digital Forensics investigation, and present the evidence in a clear and brief form to the relevant authorities or stakeholders.
Here, are some of the challenges that are faced by Digital Forensics.
Despite these challenges, a range of powerful tools and techniques are available to digital forensic investigators. Here are some examples:
