  1. Module 4: Managing Access to Resources

  2. Overview • Overview of Managing Access to Resources • Managing Access to Shared Folders • Managing Access to Files and Folders Using NTFS Permissions • Determining Effective Permissions • Managing Access to Shared Files Using Offline Caching

  3. Lesson: Overview of Managing Access to Resources • Multimedia: Access Control in Microsoft Windows Server 2003 • What Are Permissions? • What Are Standard and Special Permissions? • Practice: Examining NTFS Permissions • Multimedia: Permission States

  4. Multimedia: Access Control in Microsoft Windows Server 2003 • This presentation explains how Active Directory uses security principals and identifiers to provide access to objects • Important point to watch for: If you delete a security principle and then create it again with the same name, what is the effect on the permissions?

  5. What Are Permissions? • Permissions define the type of access granted to a user, group, or computer for an object • You apply permissions to objects such as files, folders, and printers • You assign permissions to users and groups in Active Directory or on a local computer

  6. What Are Standard and Special Permissions? Standard Permissions Special Permissions

  7. Practice: Examining NTFS Permissions In this practice, you will: • Examine the NTFS default permissions on system folders • Examine the NTFS default permissions on a newly created folder

  8. Multimedia: Permission States In this activity, you will learn the differences between the permission states and then test your knowledge

  9. Lesson: Managing Access to Shared Folders • What Are Shared Folders? • What Are Administrative Shared Folders? • Tools to Create and Manage Shared Folders • Shared Folder Permissions • Methods to Connect to Shared Folders • What Are Published Shared Folders? • How Published Shared Folders Are Used • Best Practices For Using Shared Folders • Practice: Managing Access to Shared Folders

  10. What Are Shared Folders? • Shared folders show an icon of a hand holding the folder • You can share only folders, not files • Default permission on shared folders is Everyone, Read • When you copy or move a shared folder, the folder is no longer shared • To hide a shared folder, include a $ after the name of the shared folder • Users access hidden shares by typing the UNC path

  11. What Are Administrative Shared Folders?

  12. Tools to Create and Manage Shared Folders Who can create shared folders? • On Windows Server 2003 domain controllers • Administrators group • Server Operators group • On Windows Server 2003 member or stand-alone servers • Administrators group • Power Users group Tools used to create and manage shared folders • Computer Management • Window Explorer or My Computer • The Net Share command

  13. Shared Folder Permissions

  14. Methods to Connect to Shared Folders

  15. What Are Published Shared Folders? • A published shared folder: • Is a shared folder object in Active Directory • Can maintain static friendly names • Clients: • Can search Active Directory for published shared folders • Do not need to know the name of the server to connect to a shared folder • Can search by using keywords if they do not know the exact name of the share

  16. How Published Shared Folders Are Used • Administrators can use Active Directory Users and Computers to find shared folders • Windows XP Professional clients can search Active Directory from My Network Places

  17. Best Practices for Using Shared Folders • Use the Authenticated Users group instead of Everyone • Share folders with the appropriate level of permission • Use groups to grant access rather than individual users • Publish shared folders in larger environments

  18. Practice: Managing Access to Shared Folders In this practice, you will: • Connect to an administrative share • Create a shared folder and grant permissions • Publish a shared folder and create keywords • Map a drive letter to the shared folder and test permissions

  19. Lesson: Managing Access to Files and Folders Using NTFS Permissions • What Is NTFS? • NTFS File and Folder Permissions • What Is NTFS Permissions Inheritance? • Effects on NTFS Permissions When Copying and Moving Files and Folders • Best Practices for Managing Access to Files and Folders Using NTFS Permissions • Practice: Managing Access to Files and Folders Using NTFS Permissions

  20. What Is NTFS? NTFS is a file system that provides: • Reliability • Security at the file level and folder level • Improved management of storage growth • Multiple user permissions

  21. NTFS File and Folder Permissions File permissions Folder permissions • Full Control • Modify • Read & Execute • Write • Read • Full Control • Modify • Read & Execute • Write • Read • List Folder Contents

  22. What Is NTFS Permissions Inheritance? Inherit permissions FolderA Read / Write FolderB Access to FolderB Prevent inheritance FolderA Read / Write FolderB FolderC No access to FolderB

  23. Effects on NTFS Permissions When Copying and Moving Files and Folders Copy Copy or Move NTFS Partition C:\ NTFS Partition E:\ Move NTFS Partition D:\ • When you copy files and folders, they inherit the permissions of the destination folder • When you move files and folders within the same partition, they retain their permissions • When you move files and folders to a different partition, they inherit the permissions of the destination folder

  24. Best Practices for Managing Access to Files and Folders Using NTFS Permissions • Grant permissions to domain local groups instead of to users • Group resources to simplify administration • Allow users only the level of access that they require • Grant Read & Execute permission for application folders

  25. Practice: Managing Access to Files and Folders Using NTFS Permissions In this practice, you will: • Examine and configure NTFS permissions • Block NTFS permission inheritance and set permissions • Test NTFS permissions • Test the effects of copying and moving files or folders

  26. Lesson: Determining Effective Permissions • What Are Effective Permissions on NTFS Files and Folders? • Class Discussion: Applying NTFS Permissions • Effects of Combined Shared Folder and NTFS Permissions • Class Discussion: Determining Effective NTFS and Shared Folder Permissions • Practice: Determining Effective NTFS and Shared Folder Permissions

  27. What Are Effective Permissions on NTFS Files and Folders? • NTFS permissions are cumulative • File permissions override folder permissions • Deny overrides all permissions • Creators of files and folders are their owners

  28. Class Discussion: Applying NTFS Permissions NTFS Partition Folder1 File1 Folder2 File2 • Users groupWrite for Folder1 • Sales group Read for Folder1 1 Users Group • Users groupRead for Folder1 • Sales groupWrite for Folder2 2 User1 • Users groupModify for Folder1 • File2 should only be accessible to Sales group with Read permission 3 Sales Group

  29. Effects of Combined Shared Folder and NTFS Permissions Public Full Control NTFS Volume Users Read File1 Change File2

  30. Class Discussion: Determining Effective NTFS and Shared Folder Permissions NTFS Volume NTFS Volume 1 2 Users Group Sales Group FC FC FC R FC FC Users Data User1 Sales User1 Sales Group User2 HR User2 User3 Pubs User3 Class discussion: • Determine effective NTFS permissions • Determine shared folder permissions

  31. Practice: Determining Effective NTFS and Shared Folder Permissions In this practice, you will: • Share the Legal folder • Determine the effective NTFS permissions • Determine the effective combined permissions

  32. Lesson: Managing Access to Shared Files Using Offline Caching • What Is Offline Files? • How Offline Files Are Synchronized • Offline File Caching Options • Practice: Using Offline Caching

  33. What Is Offline Files? • Offline Files is a document-management feature that provides the user with consistent online and offline access to files • Advantages of using Offline Files: • Support for mobile users • Automatic synchronization • Performance advantages • Backup advantages

  34. How Offline Files Are Synchronized • Disconnected from the network • Files are synchronized at logoff. The user works with the locally cached copy • Logged on to the network • Files are synchronized at logon. The user works with the network version of the files • If a file has been modified in both locations • The user must choose which version of the file to keep or to rename one file and keep both versions

  35. Offline File Caching Options

  36. Practice: Using Offline Caching In this practice, you will: • Manually cache a document in the Legal shared folder • Set synchronization options

  37. Lab: Managing Access to Resources In this lab, you will: • Create and share folders • Configure NTFS security • Publish shared folders • Test permissions • Configure automatic caching
