Chapter 11: Securing and Sharing Your Data
Viewing and modifying existing special permissions
You can view and set special permissions for a file or a folder by completing the fol-
1. In Windows Explorer, right-click the file or folder you want to work with and
then select Properties.
2. In the Properties dialog box, select the Security tab and then click Advanced. In
the “Advanced Security Settings for” dialog box, shown in Figure 11-5, the per-
missions are presented much as they are on the Security tab. The key difference
is that you now have additional advanced options.
3. On the Permissions tab, click Edit. This opens an editable view of the Permis-
sions tab in a new dialog box.
4. Click the existing user or group whose permissions you want to modify, and
then click Edit. This displays an editable “Permission Entry for” dialog box (see
Figure 11-6). If any permissions are shaded (unavailable), they are being inher-
ited from a parent folder. You can override the inherited permission, if neces-
sary, by selecting the opposite permission, such as Deny rather than Allow.
5. To modify existing permissions, use the Allow and Deny columns in the Permis-
sions For list. Select checkboxes in the Allow column to add permissions, and
clear checkboxes to remove permissions.
