Computer forensicsPRINCIPLE “Forensic computing is the process of - a)Identifying b)Preserving c)Analysing and d)Presenting digital evidence in a manner that is acceptable.”
FUNCTION: • Detect a computer incident, identify the intruders and prosecute the perpetrator in a court of law.
HISTORY • Began to evolve more than 30 years ago in US when law enforcement and military investigators started seeing criminals get technical. • Over the next decades, and up to today, the field has exploded. Law enforcement and the military continue to have a large presence in the information security and computer forensic field at the local, state and federal level.
NEEDS OF COMPUTER FORENSICS • To produce evidence in the court that can lead to the punishment of the actual. • To ensure the integrity of computer system. • To focus on response to hi-tech offenses, started to intertwine.
CYBER CRIME: “any illegal act that involves a computer it’s system or it’s applications”. • Burglary • Suicide • Obscenity • Homicide • Administrative investigation • stalking • Types of cyber crime : • Child prom • Breech of computer security • Fraud /Theft • Copy right violations • Identity theft • Narcotics investigations • Threats
