24. Image backup-a backup process for a computer or virtual machine (VM) that creates a copy of the operating system and all the data associated with it, including the system state, and application configurations and saves it as a single file.
25. Incremental backup- one that provides a backup of files that have changed or are new since the last incremental backup
26. Inoculation-A process used by antivirus software; compares old and current qualities of files to detect viral activity
27. IP address-) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication
28. Keystroke logger-keylogger, is a type of software that captures and logs what a user on your computer types on the keyboard
29. Logic bomb-is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met.
30. Logical port- is a software construct serving as a communications endpoint in a computer's host operating system.
31. Logical port blocking-A condition in which a firewall is configured to ignore all incoming packets that request access to a certain port so that no unwanted requests will get through to the computer
32. Macro virus-A virus that is distributed by hiding it inside a macro
33. Malware-Software that is intended to render a system temporarily or permanently useless or to penetrate a computer system completely for purposes of information gathering. Examples include spyware, viruses, worms, and Trojan horses.
34. Master boot record-A small program that runs whenever a computer boots up
35. Multipartite virus-Literally meaning “multipart” virus; a type of computer virus that attempts to infect both the boot sector and executable files at the same time.
36. Network address translation-A process that firewalls use to assign internal Internet Protocol (IP) addresses on a network
37. Packet-A small segment of data that is bundled for sending over transmission media. Each packet contains the address of the computer or peripheral device to which it is being sent
38. Packet filtering-A feature found in firewalls that filters out unwanted data packets sent to specific logical ports.
39. Packet sniffer-A program that looks at (sniffs) each data packet as it travels on the Internet

41. Pharming-Planting malicious code on a computer that alters the browser’s ability to find Web addresses and directs users to bogus Web sites.
42. Phishing-The process of sending e-mail messages to lure Internet users into revealing personal information such as credit card or Social Security numbers or other sensitive information that could lead to identity theft.
43. Polymorphic virus-A virus that changes its virus signature (the binary pattern that makes the virus identifiable) every time it infects a new file. This makes it more difficult for antivirus programs to detect the virus
44. Pretexting-The act of creating an invented scenario (the pretext) to convince someone to divulge information
45. Program file-A file that is used in the running of software programs
46. Quarantining-The placement (by antivirus software) of a computer virus in a secure area on the hard drive so that it won’t spread infection to other files.
47. Script-A list of commands (mini-programs or macros) that can be executed on a computer without user interaction
48. Script kiddy-An amateur hacker who lacks sophisticated computer skills. These individuals are typically teenagers, who don’t create programs used to hack into computer systems but instead use tools created by skilled hackers that enable unskilled novices to wreak the same havoc as professional hackers.
