The term “computer forensics” was coined in 1991 in the first training session held by the International Association of Computer Specialists (IACIS) in Portland, Oregon. Since then, computer forensics has become a popular topic in computer security circles and in the legal community. Like any other forensic science, computer forensics deals with the application of law to a science. In this case, the science involved is computer science and some refer to it as Forensic Computer Science. Computer forensics has also been described as the autopsy of a computer hard disk drive because specialized software tools and techniques are required to analyze the various levels at which computer data is stored after the fact. Computer forensics deals with the preservation, identification, extraction, and documentation of computer evidence. The field is relatively new to the private sector, but it has been the mainstay of technologyrelated investigations and intelligence gathering in law enforcement and military agencies since the mid1980s. Like any other forensic science, computer forensics involves the use of sophisticated technology tools and procedures that must be followed to guarantee the accuracy of the preservation of evidence and the accuracy of results concerning computer evidence processing. Typically, computer forensic tools exist in the form of computer software.

Malicious users intent on waging an attack against a person or system. Crackers may be motivated by greed, power, or recognition. Their actions can result in stolen property (data, ideas, and so on), disabled systems, compromised security, negative public opinion, loss of market share, reduced profitability, and lost productivity. The correct name for an individual who hacks into a networked computer system with malicious intentions. The term “hacker” is used interchangeably (although incorrectly) because of media hype of the word “hacker. ” A cracker explores and detects weak points in the security of a computer networked system and then exploits these weaknesses using specialized tools and techniques.

A type of malicious software that can destroy the computer’s hard drive, files, and programs in memory, and that replicates itself to other disks. Selfreplicating, malicious code that attaches itself to an application program or other executable system component and leaves no obvious signs of its presence. The oldest form of malicious code objects that plague cyberspace. Once they are in a system, they attach themselves to legitimate operating system and user files and applications

Code objects that include a broad range of programmed computer security threats that exploit various network, operating system, software, and physical security vulnerabilities to spread malicious payloads to computer systems. Software or firmware intended to perform an unauthorized process that will have adverse impact on the confidentiality, integrity, or availability of an information system. (. See Trojan horse. )
