Computer Forensics (in the context of this document, “forensic analysis”) is the use of specialized techniques for recovery, authentication and analysis of electronic data when an investigation or litigation involves issues relating to reconstruction of computer usage, examination of residual data, authentication of data by technical analysis or explanation of technical features of data and computer usage. Computer forensics requires specialized expertise that goes beyond normal data collection and preservation techniques available to end-users or system support personnel, and generally requires strict adherence to chain-of-custody protocols.
