Highlights
Computer forensics is defined as the equivalent of surveying a crime scene or performing an autopsy, involved in all aspects of an investigation. It addresses a wide range of crimes and disputes, including fraud and theft.
The term 'forensic' originates from a Latin word meaning 'forum' or 'discussion,' where criminal cases were presented. The video details various subdivisions of forensic science, such as forensic pathology, accounting, anthropology, archaeology, chemistry, and DNA analysis, each applying scientific principles to legal questions.
The timeline of computer forensics began in the 1970s with early computer crime cases. Key developments include the creation of forensic utilities like 'unerased' in the 1980s, the formation of organizations like HTCIA and IIC, and the establishment of FBI's magnetic media program, which evolved into the Computer Analysis and Response Team. International conferences and guidelines for digital evidence also marked significant milestones.
Important standards in computer forensics include examining copies instead of original media, using write-blocking technology, supervisor review of results, testing hardware and software, and maintaining objectivity. The forensic process consists of five basic steps: preparation, collection, examination, analysis, and reporting.
This section elaborates on the core phases: Collection (identifying, labeling, acquiring data), Examination (processing collected data using automated and manual methods), Analysis (interpreting examination results to derive useful information), and Reporting (documenting actions, explaining procedures, and providing recommendations for improvement).
Cybercrime encompasses crimes made possible by computers, such as network intrusions and virus dissemination, as well as computer-based variations of traditional crimes like identity theft, stalking, and terrorism. It categorizes computer crime into three types: computer as a target (e.g., spreading viruses), computer as a weapon (e.g., fraud), and computer as an accessory (e.g., storing illegal information).
Examples of cybercrime include data breaches (LinkedIn, Harmony, Twitter password leaks), theft of telecommunication services, sales and investment frauds, and electronic fund transfer frauds. Cybercrime problems extend to electronic vandalism, terrorism, extortion, piracy, pornography, and various telemarketing and electronic money laundering frauds.
The growth of cybercrime has led to the creation of numerous jobs in law enforcement (CIA, FBI, local police), private sector information security, cyber tech official roles in companies, technology fields in accounting and law firms, and military intelligence. A good investigator needs the highest level of ethics, unbiased judgment, strong documentation skills, awareness of when to seek help, and good communication skills.
