WGU- D322 Intro to IT Test Questions
and Answers All Correct
Strategic risk analysis - Answer-security policies are translated into mechanisms which
support information security. We will focus on the risk management process
Social engineering - Answer-threat that targets users.
Phishing - Answer-is the process of targeting a specific individual, usually via email,
under the guise of a reputable or trustworthy entity to reveal private or personal details
such as usernames or password
Hacking - Answer-is when an individual obtains unauthorized access to a host
Malware - Answer-"malicious" software
Spyware - Answer-is often downloaded unknown to the user when accessing web
storages.
Denial of service (DOS) attack - Answer-In the DOS attack, one or more attackers
attempts to flood a server with so many incoming messages that the server is unable to
handle legitimate business
Firewalls - Answer-prevent certain types of messages from coming into or out of the
network and anti-viral software seeks out malware
Antivirus software - Answer-attempts to identify if a file contains a virus or, more
generally, some form of malware.
Information security - Answer-attempts to ensure the confidentiality, integrity, and
availability of information when it is stored, processed, and transmitted (across a
network)
Encryption - Answer-is the idea of obfuscating the information that resides on a
computer or is sent over a network so that if it is intercepted the hacker will be unable to
use the information. Encryption uses a mathematical algorithm for converting the plain-
text information to the encrypted form
Symmetric key encryption - Answer-uses the same key for performing the encryption
and decryption.
, Public-key encryption - Answer-uses two keys, a public and private key.
Software - Answer-is the term we use for the systems and programs that are developed,
as a result of programming and scripting efforts by individuals, to perform a business
function
Application software - - Answer-consists of programs that end users run to accomplish
tasks
System software - Answer-consists of programs that make up the operating system
Server software - Answer-works with hardware to provide a network service
Cloud computing - Answer-combines several different technologies: distributed
computing, computer networks, and storage area networks. The idea is to offer, as a
service, the ability to offload computation and storage from your local computer to the
cloud
Operating system (OS) - Answer-is a program. Its primary task is to allow a computer
user to easily access the hardware and software of a computer system. Beyond this, we
might say that an OS is required to maintain the computer's environment. (Windows
7/8/10, Linux,and Mac OS X., Android, Windows, and iOS)
Operating System Components
(System software) - Answer-User
Applications
OS utilities
Services
Shells
OS Kernel
Software device drivers
OM BIOS drivers
Hardware
Kernel - Answer-The core components of the operating system
Device drivers - Answer-provide specific interfaces between the OS running a computer
and hardware
Shell - Answer-an interface for the user, often personalized for that given user
System utilities - Answer-programs that allow the user to monitor and improve system
performance.
GUI - Answer-allows a user to control the computer by using the mouse and pointing
and clicking at objects on the screen (icons, menus, buttons, etc.).
