<New scan scope> window

In this window, you can add and configure scan scopes.

Scan scope settings

Setting	Description
Scan scope name	Field for entering the scan scope name. This name will be displayed in the table in the Scan scopes window. The entry field must not be blank.
Use this scope	This check box enables or disables scans of this scope by the application. If this check box is selected, the application processes this scan scope. If this check box is cleared, the application does not process this scan scope. You can later include this scope in the component settings by selecting the check box. The check box is selected by default.
File system, access protocol, and path	The settings block lets you set the scan scope. You can select the file system type in the drop-down list of file systems: Local (default value) – local directories. If this item is selected, you need to indicate the path to the local directory. Mounted – Mounted remote or local directories. If this item is selected, you need to indicate the protocol or name of the file system. Shared — The protected server's file system resources accessible via the Samba or NFS protocol. All remote mounted – all remote directories mounted on the device using the Samba and NFS protocols. All shared — All of the protected server's file system resources accessible via the Samba and NFS protocols.
	If Shared or Mounted is selected in the drop-down list of file systems, you can select the remote access protocol in the drop-down list on the right: NFS: remote directories mounted on a device using the NFS protocol. Samba: remote directories mounted on a device using the Samba protocol. Custom – resources of the device's file system specified in the field below.
	If Local is selected in the drop-down list of file systems, then in the input field you can enter a path to a directory that you want to add to the scan scope. You can use masks to specify the path. You can use the `` (asterisk) character to create a file or directory name mask. You can indicate a single `` character to represent any set of characters (including an empty set) preceding the `/` character in the file or directory name. For example, `/dir//file` or `/dir///file`. You can indicate two consecutive `` characters to represent any set of characters (including an empty set and the `/` character) in the file or directory name. For example, `/dir/*/file/` or `/dir/file/`. The `` mask can be used only once in a directory name. For example, `/dir///file` is an incorrect mask. You can use a single `?` character to represent any one character in the file or directory name. The / path is specified by default – the application scans all directories of the local file system. If the Local type is selected in the drop-down list of file systems, and the path is not specified, the application scans all directories of the local file system.
Filesystem name	The field for entering the name of the file system where the directories that you want to add to the scan scope are located. The field is available if the Mounted type is selected in the drop-down list of file systems and the Custom item is selected in the drop-down list on the right.
Masks	The list contains name masks for the objects that the application scans. By default the list contains the * mask (all objects). You can add, edit, or delete masks. Clicking the Delete button removes the selected item from the table. This button is available if at least one item is selected in the table. The selected element's settings are changed in a separate window. Clicking the Add button opens a window where you can specify the new item settings.

If this check box is cleared, the application includes this area in the scan scope. You can later exclude this scope by selecting the check box.

The check box is selected by default.

File system, access protocol, and path

The settings block lets you set the exclusion scope.

In the drop-down list of file systems, you can select the type of file system of the directories to be excluded from scans:

Local, for local directories.
Mounted – mounted directories.
All remote mounted – all remote directories mounted on the device using the Samba and NFS protocols.

If Mounted is selected in the drop-down list of file systems, you can select the remote access protocol in the drop-down list on the right:

NFS: remote directories mounted on a device using the NFS protocol.
Samba: remote directories mounted on a device using the Samba protocol.
Custom – resources of the device's file system specified in the field below.

If Local is selected in the drop-down list of file systems, then in the input field you can enter a path to a directory that you want add to the exclusion scope. You can use masks to specify the path.

You can use the * (asterisk) character to create a file or directory name mask.

You can indicate a single * character to represent any set of characters (including an empty set) preceding the / character in the file or directory name. For example, /dir/*/file or /dir/*/*/file.

You can indicate two consecutive * characters to represent any set of characters (including an empty set and the / character) in the file or directory name. For example, /dir/**/file*/ or /dir/file**/.

The ** mask can be used only once in a directory name. For example, /dir/**/**/file is an incorrect mask.

To exclude the mount point /dir, you need to specifically indicate /dir (no asterisk).

The mask /dir/* excludes all mount points at the level below /dir but not /dir itself. The /dir/** mask excludes all mount points below the level of /dir but not /dir itself.

You can use a single ? character to represent any one character in the file or directory name.

The / path is specified by default. The application excludes all directories of the local file system from scan.

Filesystem name
