Computer forensics is the scientific examination and analysis of data held on, or retrieved from, computer storage media in such a way that the information can be used as evidence in a court of law. It may include the secure collection of computer data; the examination of suspect data to determine details such as origin and content; the presentation of computer based information to courts of law; and the application of a country’s laws to computer practice. Forensics may involve recreating “deleted” or missing files from hard drives, validating dates and logged in authors/editors of documents, and certifying key elements of documents and/or hardware for legal purposes..”
