Itt operating systems unit 05 lesson 06

This document discusses managing permissions in Windows and configuring printing. It covers NTFS and share permissions, the Windows permission architecture including ACLs and ACEs, and standard and special NTFS permissions. It also discusses sharing files and folders using Homegroups, public folders, and any folder sharing. The document concludes with an overview of the Windows printing architecture, adding local and shared printers, and managing printer permissions and documents.

Managing Permissions NTFS permissions Share permissions Registry permissions Active Directory permissions
Windows Permission Architecture Access Control List (ACL) Access Control Entries (ACEs) Security principal Folder ACL Sales – Read Managers – Full Control JSmith – Deny Access ACEs Security Principal Permission
The Security Tab
Standard 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.
Advanced Security Settings Dialog Box
Allowing 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
Inheriting Permissions
Copying 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
Effective 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.

Assigning Standard NTFS Permissions
NTFS Standard Permissions – Full Control Folder Modify the folder permissions. Take ownership of the folder. Delete subfolders and files contained in the folder. Perform all actions associated with all of the other NTFS folder permissions. File Modify the file permissions. Take ownership of the file. Perform all actions associated with all of the other NTFS file permissions.
NTFS Standard Permissions – Modify Folder Delete the folder. Perform all actions associated with the Write and the Read & Execute permissions. File Modify the file. Delete the file. Perform all actions associated with the Write and the Read & Execute permissions.
NTFS Standard Permissions – Read & Execute Folder Navigate through restricted folders to reach other files and folders. Perform all actions associated with the Read and List Folder Contents permissions. File Perform all actions associated with the Read permission. Run applications.
NTFS Standard Permissions – List Folder Folder View the names of the files and subfolders contained in the folder. File Not applicable
NTFS Standard Permissions – Read Folder See the files and subfolders contained in the folder. View the ownership, permissions, and attributes of the folder. File Read the contents of the file. View the ownership, permissions, and attributes of the file.
NTFS Standard Permissions – Write Folder Create new files and subfolders inside the folder. Modify the folder attributes. View the ownership and permissions of the folder. File Overwrite the file. Modify the file attributes. View the ownership and permissions of the file.
Assigning Special NTFS Permissions
Resource 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.
SHARING FILES AND FOLDERS
Folder Sharing in Windows 7 Any folder sharing Public folder sharing Homegroup sharing
Sharing with Homegroups Uses the Home network location to share the contents of libraries among all users Automatically configured Shares libraries in the users profiles Can add libraries
Creating a Homegroup
Working with Homegroups
Sharing the Public Folder 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 Sharing Full control over what material on the computer is shared Which users have access and to what degree they have access
Managing 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.

WORKING WITH PRINTERS
Windows Print Architecture
Windows Printing Flexibility Stand-alone local printing Printer shared on the network Print device connected directly to LAN Create a printer pool (one print server with more than one print device) Connect multiple printer servers to a single print device
Adding a Local Printer Most common configuration for home, small business, or workgroups Local users can print their own jobs Can share the printer with other network users
Add a Local Printer 1
Add a Local Printer 2
Sharing a Printer
Configuring 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.
Printer Permissions
Managing Documents Pausing, resuming, restarting, and canceling documents in the print queue
Managing Printers Printer priority Scheduling printer access Creating a Printer Pool
Skills 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.
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.
