What is Digital forensics
Digital forensics is a branch of forensic science that involves the collection, preservation, analysis, and presentation of electronic data that can be used as evidence in a court of law. This field typically deals with digital devices such as computers, mobile phones, digital cameras, and other electronic devices that may contain information relevant to a criminal investigation or civil lawsuit.
The main goal of digital forensics is to gather and analyze digital evidence in a way that is admissible in court and that can help investigators determine how a crime was committed and identify the person or people responsible. This can involve analyzing data from hard drives, recovering deleted files, analyzing network traffic, and examining metadata to determine who accessed a particular file and when.
Benefits of performing Digital Forensics
- Cybercrime investigation: Digital forensics can assist law enforcement authorities in investigating a variety of cybercrimes such as hacking, phishing, identity theft, and cyber espionage. Digital forensics techniques can be used by investigators to extract evidence from computers, mobile devices, and networks in order to identify suspects, trace the origin of attacks, and convict criminals.
- Intellectual property theft: Cases of intellectual property theft, such as copyright infringement, patent breaches, and trade secret theft, can be investigated using digital forensics. Forensic experts can examine digital data to determine whether a specific person or organisation has stolen or misappropriated intellectual property.
