Digital forensics is a branch of cybersecurity that involves the process of identifying, preserving, analyzing, and documenting digital evidence. It is the process of storing, analyzing, retrieving, and preserving electronic data that may be useful in an investigation. Digital forensics is concerned with the identification, preservation, examination, and analysis of digital evidence, using scientifically accepted and validated processes, to be used in and outside of a court of law. It includes data from hard drives in computers, mobile phones, smart appliances, vehicle navigation systems, electronic door locks, and other digital devices. Digital forensics is used in both criminal and private investigations, and it is concerned with the recovery and investigation of material found in digital devices and cybercrimes. Digital forensics experts are also hired by the private sector as part of cybersecurity and information security teams to identify the cause of data breaches, data leaks, cyber attacks, and other cyber threats. The skills needed for digital forensics in cybersecurity include knowledge of computer networking concepts and protocols, risk management processes, laws, regulations, policies, and ethics as they relate to cybersecurity and privacy, and knowledge of operating systems, among others.
