What is Digital Forensics?

Digital Forensics is a branch of forensic science focused on identifying, collecting, preserving, analysing, and presenting digital evidence. It is a critical discipline in investigations involving cybercrimes, data breaches, fraud, intellectual property theft, and more. The primary goal of digital forensics is to extract meaningful evidence from digital devices such as computers, mobile phones, and network systems while maintaining data integrity. Digital forensic practices ensure the evidence is admissible in a court of law or serves investigative purposes.
