IS3340 CHAPTER 5 Flashcards
Software that intercepts all incoming (and optionally outgoing) information, scanning each message or file for malware content is called ___?
ANTI-MALWARE SHIELD
Software designed to detect and mitigate spyware is called ___?
ANTI-SPYWARE SOFTWARE
Software designed to detect and mitigate some types of malware, including mainly viruses, worms, and Trojan horses is called ___?
ANTIVIRUS SOFTWARE
A condition in which a running program stores data that is larger than the memory location set aside for the data is called ___?
The extra data spills spills over into adjacent memory, causing other data and possibly instructions to be overwritten. An attacker can place specific data in this area to change the instructions a program executes.
BUFFER OVERFLOW
The practice of identifying malware based on previous experience is called ___?
HEURISTICS
Software that is designed to infiltrate a target computer and make it do something the attacker has instructed it to do is called ___?
MALICIOUS SOFTWARE
A common term used to describe malicious software, including viruses, worms, and Trojan horses, especially in combinations is called ___?
MALWARE
Software that modifies or replaces one or more existing programs, often part of the operating system, to hide the fact a computer has been compromised is called a ___?
ROOTKIT
The unique set of instructions that make up an instance of malware and distinguish it from other malware is called ___?
SIGNATURE
An organized collection of malware signatures used by antivirus or anti-spyware (or other anti-malware) software to identify malware is called ___?
SIGNATURE DATABASE
Software that covertly monitors and records pieces of information such as Web surfing activities and all data process by the browser is called ___?
SPYWARE
Software that masquerades as an apparently harmless program or data file but contains malware instructions is called ___?
TROJAN HORSE
A software program that attaches itself to, or copies itself into, another program for the purpose of causing the computer to follow instructions that were not intended by the original program developer is called ___?
VIRUS
Active malware that either exploits an unknown vulnerability or one for which no fix has yet been released is called ___?
