Chapter 14: Users, Groups, and Permissions
Take Ownership
- Administrators can use the ____________ permission to seize any file or folder on a computer, even those you don't actively share.
The 4 situations of Permission Propagation
- 1. Copying data within one NTFS-based volume. - 2. Moving data within one NTFS-based volume. - 3. Copying data between two NTFS-based volumes. - 4. Moving data between two NTFS-baed partitions.
Examples of common actions that require administrator privileges
- 1. Installing and uninstalling applications - 2. Installing a driver for a device - 3. Installing Windows Updates - 4. Adjusting Windows Firewall settings - 5. Changing a user's account type - 6. Browsing to another user's directory
The three groups of rwx stand for what?
- 1. Owner - Permissions for the owner of this file or folder. - 2. Group - Permissions for members of the group for this file or folder. - 3. Everyone - Permissions for anyone for this file or folder.
The 2 issues with permission propagation
- 1. Whether the data is being copied or moved. 2. Whether the data is coming from the same volume or a different one.
Home Groups
- A Home network that can share files and printers.
UAC Classification: Verified
- A digitally signed, third-party program or non-core OS program. - Are not part of the core of Vista and usually written by third parties. - Programs do have valid, verified certificates. - Dialog box is a gray-blue banner.
UAC Classification: Published by Vista
- A program that is a core part of the OS. - Written as part of the core of Vista and show up with a teal-bannered dialog box.
Multiple Groups
- A single account can be a member of:
Partitions
- Early version of Windows refer to grouping of cylinders or transistors on an HDD or SSD as:
Encrypting File System & BitLocker
- Advanced editions of Windows add a system that can encrypt files and folders called _______ and the most advanced editions feature drive encryption through _________.
Security Policies
- Are just rules we apply to users and groups to do everything but NTFS permissions. - Examples: Forcing anyone who logs on to your system to use a password that's at least 8 characters long.
Trusted Platform Module (TPM)
- BitLocker requires a special chip on the motherboard to function and it is called: - This chip validates on boot that the computer has not changed, that you still have the same OS installed and that the computer wasn't hacked by some malevolent program. - Also works in cases where you move the BitLocker drive from one system to another.
chmod command
- Command used to change permissions that uses a nonintuitive (means feels untrue) numbering system.
User Account Control (UAC) / VISTA
- Common in Vista and it manifested as a pop-up dialog box that seemed to appear every time you tried to do anything on a Windows Vista system.
Volumes
- Current version of Windows refer to groupings of cylinders or transistors on an HDD or SSD as:
Third-from-top level
- Displays a consent form and this consent form just pops up like a normal dialog box.
To enable BitLocker
- Double-click the BitLocker Drive Encryption icon in the classic Control Panel, or select security in the Control Panel Home view and then click Turn on BitLocker.
Chown command chown <new owner> filename
- Enables us to change the owner and the group with which a file or folder is associated. - Uses the following syntax.
User Account Control
- Enables users to know when they are about to do something that has serious consequences.
BitLocker to Go
- Enables you to apply BitLocker Encryption to removable drives, like USB-based flash drives. - Applies encryption and password protection, but doesn't require a TPM chip.
BitLocker Drive Encryption (BDE)
- Encrypts the whole drive, including every user's files and is not dependent on any noe account. - If your hard drive is stolen, all of the data on the hard drive is safe.
Administrative Shares
- Every version of Windows comes with several default shares, notably all hard drives. - They give local administrators administrative access to these resources, whether they log on locally or remotely. - You cannot change the default permissions on them. - You can delete them but Windows will re-create them automatically overtime you reboot. - They are hidden and they have been exploited by malware programs because users who setup their computers don't give the administrator account a password.
Characteristics of Local Security Policy
- Has a number of containers that help organize the many types of policies on a typical system. - Under each container are subcontainers or preset polices.
Windows Home Edition
- Have basically no security features?
Step 2: Add/Edit Users and/or Groups
- Head over to the Security tab. - You will notice two sections: the top section is a list of users and groups that currently have NTFS permissions to that folder, and the bottom section is a list of NTFS permissions for the currently selected users and groups.
Dialog
- If a Standard User attempts to do something that requires administrator privileges, he or she sees a __________ box that prompts for the administrator password.
Simpler UAC dialog box

Passwords / Part of securing User accounts
- A way to secure user account is by:
Important point 5 about NTFS permissions
- Administrators do not automatically have complete control over every folder and file. - If an administrator wants to access a folder or file they do not have permission to access, they may go through a process called Take Control.
Connecting to a Microsoft account
- Allows great benefits like data synchronization like logging you into Skype if you have Skype and iCloud services.
Power Users / Power Users group
- Almost as powerful as members of the Administrators group, but they cannot install new devices or access other users' files or folders unless the files or folders specifically provide them access. - Standard user that can install apps and make some configurations. A legacy type of user.
Change permission
- An account with this permission can give or take away permissions for other accounts.
Parental Controls (1)
- An administrator account can monitor and limit the activities of any standard user in Windows, a feature that gives parents and managers an excellent level of control over the content their children and employees can access.
Take Ownership permission
- Anyone with the permission can seize control of a file or folder. - Administrator accounts have Take Ownership permission for everything. - If you own a file, you can prevent anyone from accessing that file. - An Administrator whom you have blocked can take ownership away from you and then access that file.

- Because limited users can't do common tasks, most users create an ______________ account and log on. - Such accounts have full control over the computer, so any malware or any simple user mistake that slips in through the account can do a lot of harm.
Third thing tech should know to see what happens when you copy or move an object, such as a file or folder
- Copying from one NTFS volume to another creates 2 copies of the object. - The copy of the object in the new location INHERITS the permissions from that new location. - The new copy can have different permissions than the original.
First thing tech should know to see what happens when you copy or move an object, such as a file or folder
- Copying within a volume creates two copies of the object. - The copy of the object in the new location INHERITS the permissions from that new location. - The new copy can have different permissions than the original.
Best Practice way to give NTFS permissions
- Create users and put the users into groups and give NTFS permissions to those groups. - Set NTFS permissions on a per folder basis for individual groups.
NTFS permissions
- Define exactly what any particular account can or cannot do to the file or folder and are quite detailed and powerful. - Example: You can set up ________ permissions allowing a user account to edit a file but not delete it. - Example: You could also configure _______ permissions to enable any member of a user group to create a subfolder for a particular folder.
Permissions
- Define exactly what users may do to a resource on the system.
Folder permissions
- Define what a user may do to a folder. - Example: "List folder contents," which gives the permission to see what's in the folder.
File permissions
- Define what a user may do to an individual file. - Example: "Read and Execute," which gives a user account the permission to run an excitable program.
The level of access
- Defined by a set of restrictions called NTFS permissions.
User account characteristics
- Each user account gets unique personal folders, such as Documents, Desktop, Pictures, Music, and more. - By default, only a person logged in as a specific user can access the personal folders for that user account. - For every different User account you have, you can set NTFS permissions for each of the gummy bears (USER ACCOUNT).
Guests / Guests group
- Enables someone who does not have an account on the system to log on by using a guest account. - Example: Might use this feature at a party, to provide casual Internet access to guests, or at a library terminal. - Limited Account - Makes no changes at all.
local user account
- Every Windows system stores the user accounts as an encrypted database of user names and passwords. - Windows calls each record in this database a:
How to add or remove NTFS permissions
- First select the user or group you wish to change and then clicking Edit to open a Permissions dialog box. - To add NTFS permission, select the allow checkbox next to the NTFS permission you want to add. - You remove an NTFS permission by deselecting the allow checkbox next to the NTFS permission you want to remove.
Administrators / Administrators group
- Grants complete control of the machine. - Any account that is a member of the Administrators group has complete _______ privileges. - Common for the primary user of a Windows system to have her account in the Administrators group. - Example: When you create the Jane user account and make Jane an administrator, your placing Jane in the Administrators group.

- In Windows 8.1 enables you to create a new user account based on a global Microsoft account. - Accounts from _______ charm is the primary graphical place where Windows 8 wants you to create users.
A group (Container)
- Is a container that holds user accounts and defines the capabilities of its members. - Is an organization method. - An efficient way of managing multiple users, especially when you are dealing with a whole network of accounts. - Standalone computers like home users can rely on this too. - You can have a group called Movie watchers and another group called Movie Adders. - Makes it easier to assign permissions to these different groups and add users to appropriate group.
Activity Reporting
- Logs a user's successful and blocked attempts to run an application, visit a Web site, download a file, and more. - Enable you to limit the time that standard users can spend logged on.
non-alphanumeric characters / Part of securing User accounts
- Makes any password much more difficult to crack because of two reasons. 1. Forces the hacker to consider many more possible characters than just letters and numbers. 2. Most password crackers use a combination of common words and numbers to hack passwords.
Users / Users group (standard users)
- Members of the Users group cannot edit the Registry or access critical system files. - They can create groups but can manage only those they create.
Standard users
- Members of the users group are called: - They use apps, save files, browse the web & download. - Example: If you change the Jane account from administrator to standard user, you specifically take the Jane account out of the Administrators group and place it into the Users group. - Nothing happens with her personal files or folders, but what the Jane account can do on the computer changes rather dramatically.
User Account Control (UAC)
- Microsoft addressed the problem of administrator-level account with a feature that enables standard users to do common tasks and provides a permission dialog box when standard users and administrators do certain things that could potentially harm the computer. - A security feature introduced in Windows Vista to prevent unauthorized changes to Windows.
Fourth thing tech should know to see what happens when you copy or move an object, such as a file or folder
- Moving from one NTFS volume to another creates one copy of the object. - The object in the new location INHERITS the permissions from that new location. - The newly moved file can have different permissions than the original.
Second thing tech should know to see what happens when you copy or move an object, such as a file or folder
- Moving within a volume creates one copy of the object. - That object RETAINS its permissions, unchanged.
grayed-out
- NTFS Allow permissions that are __________ tells you that the permissions here are inherited. - These checkboxes cannot be changed.
Important point 2 about NTFS permissions
- NTFS permissions are assigned both to user accounts and groups, although it's considered best practice to assign permissions to groups and then add user accounts to groups instead of adding permissions directly to individual user accounts.
User Security
- NTFS permissions are windows strongest attribute for:

1. The list details every user and group with access to that file or folder. 2. The list specifies the level of access each user or group has to that file or folder.
Groups make Windows administration much easier in two ways
1. You can assign a certain level of access for a file or folder to a group instead of to just a single user account. - Example: You can make a group called Accounting, and put all user accounts for the accounting department in that group. If a person quits, you don't need to worry about assigning all of the proper access levels when you create a new account for his or her replacement. - After you make the account for the new person, just add her account to the appropriate access group. 2. Windows provides numerous built-in groups with various access levels already predetermined.
