Standard and Special PermissionsStandard and Special Permissions
• Permissions allow you to grant specific degrees of access to security principals.
• Preconfigured permission combinations are called Standard Permissions.
• Special Permissions are more granular and can be applied individually, but are rarely used.

Allowing and Denying PermissionsAllowing and Denying Permissions
• Additive– Start with no permissions and then
grant Allow permissions (preferred method)
• Subtractive– Start by granting Allow permissions
and then grant Deny permissions

Copying and Moving NTFS FIlesCopying and Moving NTFS FIles• Copy file to a folder within NTFS volume,
inherits folder permissions• Copy file to a folder between NTFS
volumes, inherits folder permissions• Move file to a folder between NTFS
volumes, inherits folder permissions• Move file to a folder within NTFS volume,
retain permissions regardless what permissions the folder may have
• Copy or move file from FAT32 to NTFS volume, inherits folder permissions
![Page 11: Itt operating systems unit 05 lesson 06](https://reader035.fdocuments.net/reader035/viewer/2022062220/555895b1d8b42a2a738b4751/html5/thumbnails/11.jpg)
Effective PermissionsEffective Permissions
• The combination of Allow permissions and Deny permissions for each security principal:– Allow permissions are cumulative.– Deny permissions override Allow
permissions.– Explicit permissions take precedence
over inherited permissions.

Resource OwnershipResource Ownership
• Every file and folder on an NTFS drive has an owner.
• The owner always has the ability to modify the permissions, even if current permissions settings deny them access.
• The owner is the person who created the file or folder.
• Others with the “Take Ownership” permission can become the owner.

• Simplest way to give clients file sharing capability (small business networking)
• Network Discovery and Public Folder Sharing must be turned on
• Copy files to be shared to the Public folder

Any Folder SharingAny Folder Sharing• Full control over
what material on the computer is shared
• Which users have access and to what degree they have access

Managing Share PermissionsManaging Share Permissions• Share permissions
are independent from other permissions.
• With Password Protected Sharing enabled, users must have user accounts on the computer or in a domain.

• Stand-alone local printing• Printer shared on the network• Print device connected directly to

server with more than one print device)
• Connect multiple printer servers to a single print device

Configuring Printer SecurityConfiguring Printer Security• When password
protected sharing is turned on, users must log on to the computer with a user account that has a password.
• Users must have the appropriate permissions to access the printer.

Skills SummarySkills Summary• Windows 7 has several sets of permissions,
which operate independently of each other, including NTFS permissions, share permissions, registry permissions, and Active Directory permissions.
• NTFS permissions enable you to control access to files and folders by specifying just what tasks individual users can perform on them.
• Share permissions provide rudimentary access control for all of the files on a network share.
![Page 44: Itt operating systems unit 05 lesson 06](https://reader035.fdocuments.net/reader035/viewer/2022062220/555895b1d8b42a2a738b4751/html5/thumbnails/44.jpg)
Skills Summary (cont.)
• The printing architecture in Windows is modular, consisting of the print device, a printer, a print server, and a printer driver.
• A local printer is one that supports a print device directly attached to the computer or attached to the network.
• A network printer connects to a shared printer hosted by another computer.
