Users, Groups, And Permissions Flashcards
The process of identifying and granting access to some user, usually a person, who is trying to access a system
Authentication
The process that defines what resources an authenticated user can access and what he or she may do with those resources. For Windows’ files and folders, it is controlled by NTFS file system, which assigns permissions to users and groups
Authorization
A container that holds user accounts and defines the capabilities of its members. An efficient way of managing multiple users, especially when you’re dealing with a whole network of accounts
Group
Members of this group have complete control over a machine
Administrators
Members of this group are almost as powerful as administrators but they cannot install new devices or access other users’ files or folders unless the files or folders specifically provide them access
Power Users
Members of this group cannot edit the Registry or access critical system files. They can create groups but can only manage only those they create
Users
Enables someone who doesn’t have an account on the system to log on
Guests
Rulesets, connected to every folder and file in your system, that define exactly what any account or group can or cannot do to the file or folder
NTFS Permissions
When you create a new file or folder on an NTFS partition, you become the owner of that file or folder
Ownership
Anyone with the permission can seize control of a file or folder. Administrators have this for everything
Take Ownership Permission
An account with this permission can give or take away permissions for other accounts
Change Permissions
Define what a user may do to a folder
Folder Permissions
Define what a user may do to an individual file
File Permissions
Determines what NTFS permissions are applied to files that are moved or copied into a new folder. Doesn’t necessarily inherit the folder’s NTFS permissions
Permissions Propagation
Copying within a volume creates two copies of the object. The copy of the object in the new location _______ the permission from that new location
Inherits
Moving within a volume creates one copy of the object. That object ______ its permissions, unchanged.
Retains
Copying from one NTFS volume to another creates two copies of the object. The copy of the object in the new location _______ the permissions from that new location. The new copy can have different permissions than the original
Inherits
Moving from one NTFS volume to another creates one copy of the object. The object in the new location _______ the permission from that new location. The newly moved file can have different permissions than the original
Inherits
Owner (permissions for the owner of this file or folder), group (permissions for members of the group for this file or folder), everyone (permissions for anyone for this file or folder), r (read the contents of a file), w (write or modify a file or folder), x (execute a file or list the folder contents)
Linux permissions
Rwxrwxrwx where the first three are for the owner, the second three are for the group, and the last three are for everyone
Linux permission format
Command that enables you to change the owner and the group with which a file or folder is associated
Chown command
chown filename
chown syntax
Command that is used to change permissions. Uses an addition system that gives r a value of 4, w a value of 2, and x a value of 1
chmod command
chmod
chmod syntax
