Understanding Computer Forensics and Its Significance
What is Computer Forensics?
Computer forensics, often called digital forensics, involves the identification, preservation, analysis, and presentation of electronic evidence. It plays a crucial role in criminal investigations, corporate security, and incident response, helping professionals uncover digital footprints related to cybercrimes, data breaches, or unauthorized activities. The ultimate goal is to establish a factual timeline and gather admissible evidence for legal proceedings.
