If no ACEs in an ACL apply to a user, that user is denied access to the object. In other words, not explicitly having privileges to an object is exactly the same as being explicitly denied access.

When you assign permissions directly to an object, you create an explicit permission. Assigning explicit permissions to every individual folder, file, registry value, and Active Directory object would be a ponderous task. In fact, managing the massive number of ACLs that would be required would have a significant impact on the performance of Windows Server 2003. To make managing permissions more efficient, Windows Server 2003 includes the concept of inheritance. When Windows Server 2003 is initially installed, most objects have only inherited permissions. Inherited permissions propagate to an object from its parent object. For example, the file system uses inherited permissions. Therefore, each new folder you create in the root C:\ folder inherits the exact permissions a s s i g n e d t o the C:\ folder. Similarly, each subkey you create in the HKEY_LOCAL_MACHINE\Software\ key inherits the exact permissions assigned to the parent key.

At a command line, by using Cacls or XCacls Two command-line tools exist for modifying ACLs: Cacls and XCacls. You can use either manually, but they are more commonly used within a batch file. You can call such a batch file from your application s setup routine. From within an assembly The .NET Framework includes no native way to control ACLs. However, you can configure ACLs from your application by calling command-line tools or by referencing Microsoft Win32 security application programming interfaces (APIs).

The sections that follow describe each of these different techniques.
Lesson 1: Protecting Files Using Access Control Lists
How to Configure ACLs Using Windows Explorer
To set, view, change, or remove permissions for files and folders by using Windows Explorer, follow these steps: 1. Open Windows Explorer, and then locate the file or folder for which you want to set special permissions. 2. Right-click the file or folder, click Properties, and then click the Security tab, as shown in Figure 4-1.

3. In the Group Or User Name list, click a group or user. The Permissions list will display that security principle s ACLs. 4. You can now perform the following actions:
To modify a group or user s ACLs, select or clear the appropriate check boxes in the Permissions list. To add users or groups, click the Add button. In the Enter The Object Names To Select box, type the name of the user or group using the format domainname \name. When you are finished, click OK. To remove an existing user s ACL, click the group or user, and then click Remove.

5. To modify special permissions, click Advanced, and then do one of the following:
To set special permissions for a new group or user, click Add. In the Name box, type the name of the user or group using the format domainname \name. When you are finished, click OK to automatically open the Permission Entry dialog box. To view or change special permissions for an existing group or user, click the name of the group or user and then click Edit. To remove a group or user and its special permissions, click the name of the group or user and then click Remove. If the Remove button is unavailable, clear the Allow Inheritable Permissions check box. The file or folder will no longer inherit permissions.
This book does not describe individual special permissions for other types of objects, nor how to edit them. However, the user interface for editing special permissions for other objects is similar to that for files and folders. How to Override Inheritance for a New Permission After you set permissions on a parent object, new child objects automatically inherit these permissions. You can override this default behavior when adding a new permission, however. Using the file system as an example, if you do not want child folders to inherit a new permission, follow these steps: 1. Use Windows Explorer to view the folder s properties. 2. Click the Security tab, and then click the Advanced button. 3. In the Advanced Security Settings dialog box, click the Add button. 4. In the Select User Or Group dialog box, specify the user or group that the ACE will apply to, and then click OK. 5. In the Permission Entry dialog box, select This Folder Only in the Apply Onto list when you specify permissions for the parent folder, as shown in Figure 4-2. To specify permissions that do not apply to the parent folder, but exist only to be inherited, select Subfolders And Files Only, Subfolders Only, or Files Only. Other objects, such as the registry, provide similar functionality.
If the Apply Onto list is dimmed, the permission was inherited from the parent. You can change inheritance only for explicit permissions.
