Term
What determines how UAC dialog boxes will appear on your computer?
Definition
The way UAC dialog boxes appear on your computer depends on your permission level. The dialog box displayed for an administrator differs from the one displayed for a standard user. This helps to limit the tasks that can be performed by a standard user.
Term
(T/F)
You do not require administrative privileges for all tasks under UAC.
Definition
True
Term
What types of tasks can a standard user typically perform under UAC?
Definition

Term
(T/F)
applications that have not been verified and digitally signed will be verified under UAC, but require administrator privileges.

Term
Windows 7 increases computer security by making all three UAC dialog boxes ____ .
Definition
modal
Term
What does it mean if a dialog box is modal?
Definition
This means that you must respond to these boxes before you can continue any task. This further helps to maintain the security of your computer.
Term
What is the Windows 7 UAC strategy for accoun types to maintain security and flexibility?
Definition
For security, Microsoft recommends that all users log on as standard users. As a standard user, you can send e-mails, browse the Internet, and use most applications. UAC prompts standard users to enter an administrative password whenever they are about to perform tasks requiring administrative rights, such as installing a new program. As a result, standard users do not need to switch to an administrator account each time they want to perform a task requiring administrative privileges.
Term
What are the four types of notification screens you will see under UAC that request permission before certain tasks can be performed?
Definition
A Windows program needs your permission to start
A non-Windows program requires permission to start
A program created by an unknown publisher requires permission to start
You have been blocked by your system administrator from running a program
Term
if you do not recognize the publisher of a program you're installing, you should check the name of the program before deciding to install it.
Definition
name
Term
This UAC notification enables you to verify the publisher of the program you want to run
Definition
A Windows program needs your permission to start
Term
This UAC notification validates the publisher of the program so that you can be assured of its safety.
Definition
A non-Windows program requires permission to start
Term
When will you receive the UAC notification 'A non-Windows program requires permission to start'?
Definition
If you're installing a program without a valid digital signature
Term
Before you perform any installation tasks you should search the internet for the program name to validate safety 'A program created by an unknown publisher requires permission to start'.
Definition
If you're trying to run a program without a valid digital signature, UAC notifies you that the program you're trying to run has an unknown publisher. Because such programs might not be safe to run, continue only if you're certain about the program's source. If you're not sure, you can search for the program or publisher on the Internet to ensure that the program is safe.
Term
What do you need to do if you get this UAC notification: 'You have been blocked by your system administrator from running a program'?
Definition
There may be certain programs that your administrator blocks because they may not be safe to run. This is mainly true for programs whose source or publisher is not known. If you still want to run the program, you need to ask for permission from your system administrator.
Term
(T/F)

Term
Name the four security settings offered in the Action Center:
Definition
Always notify
Default - Notify me only when programs try to make changes to my computer
Notify me only when programs try to make changes to my computer (do not dim my desktop)
Never notify
Term
This setting prompts or notifies users every time they configure or install software. At the same time, this setting dims your desktop, reminding you that you need to either accept or reject the UAC request before you can perform any other task.
Definition
Action Center UAC security setting of Always notify
Term
What is the 'secure desktop'?
Definition

This setting prompts or notifies you every time you change the configuration of your computer or install software and if a program outside Windows tries to change a Windows setting.
Definition
Action Center UAC security setting of Default notify
Term
What are the exceptions to the UAC Default notify security setting notificaiton?
Definition
prompt doesn't appear if you
• change basic Windows settings
o date
o time
o update device drivers
o format partitions.
This is because these changes do not pose a security threat and are considered safe
Term
This setting is similar to the default setting. However, the difference is that this UAC notification isn't modal
Definition
Action Center UAC security setting of Notify me of changes without invoking secure desktop
Term
Why might a user wish to block the use of secure desktop?
Definition
This makes this setting less cumbersome than the default setting because you can finish your task before responding to a notification. If you've selected this setting, the frequency of notifications also reduces.
Term
What is the disadvantage of not using secure desktop?
Definition
The disadvantage of this setting is that you can easily lose track of the UAC prompts if you don’t respond to them immediately.
Term
Selecting this setting exposes your computer to potential security risks, because UAC does not notify you if software is being installed or updated on your computer or with changes to Windows settings.
Definition
Action Center UAC security setting of Never notify
Term
What could happen if you use the least secure setting for UAC?
Definition
data on your computer, including your personal data, saved files, and even protected system areas can be lost or damaged.

Term
(T/F)

UAC protects your computer against installation of malicious code or programs on your computer. It does this by asking you for permission every time a program attempts to make a major change to your computer. So it allows you to install only those applications that you trust.
Term
(T/F)
UAC doesn't display any prompt if the program you're installing has a valid digital signature.
Definition
