Change Auditor for EMC 7.3 - User Guide

Configuring audit scope

Audit only volumes, extensions and operations that are vital for your environment.

* 
NOTE: Configuring the auditing scope to audit only critical files/folders is recommended because this filtering controls the traffic between the coordinator and agent. However, changes to the auditing scope as described below will have no impact on the traffic between EMC and the agents.

Use the EMC Auditing template to specify the auditing scope for EMC events. For example, using the EMC Auditing template you can:

•
Decrease the number of volumes being audited
•
Set the Audit Path to File, Folder or Volume and enter the file, folder or volume to be audited.
•
To specify a file, enter: <ShareName>\<FolderName>\<FileName.ext>
•
To specify a folder, enter: <ShareName>\<FolderName>
•
To specify a volume, enter: <VolumeName>
•
Decrease the number of file extensions being audited
•
Use the Inclusions tab to specify individual subfolders or files to be included for auditing.
•
Use the Exclusions tab to exclude individual subfolders or files from auditing.
* 
NOTE: On both the Inclusions and Exclusions tabs, you can specify a group of files or subfolders using wildcard characters. That is, use an asterisk (*) to substitute zero or more characters or use a question mark (?) to substitute a single character.

See File/Folder Inclusion and Exclusion Examples for more information and examples.

•
Decrease the number of operations being audited
•
Use the Events tab to select only vital file and/or folder events.

File/Folder Inclusion and Exclusion Examples

This section provides sample entries for the Inclusions and Exclusions tabs on the auditing wizard. It does not list every combination available, but provides a variety of examples to help you understand how to use the wildcard characters allowed on these two tabs.

The Inclusions and Exclusions tabs only appear when the Folder, Volume or All Volumes option is selected in the Audit Path field and the Scope includes child objects. Use these two tabs as described below:

•
Inclusions tab - enter a file mask to specify what is to be audited.
•
Exclusions tab - optionally enter a file mask (or path) to specify subfolders and files in the selected audit path that are to be excluded from auditing.

Inclusions tab

You must enter a file mask on the Inclusions tab to specify what is to be audited in the selected audit path. Use the following characters to specify a file mask on the Inclusions tab:

•
Fixed characters such as letters, numbers and other characters that are allowed in file names.
•
An asterisk (*) wildcard character to substitute zero or more characters.
•
Question mark (?) wildcard character to substitute a single character.
•
A double asterisk (**) to specify a recursive match. (find match in the folder and all subfolders in audit path).
* 
NOTE: The slash (\) and double asterisk (**) characters can only be used with volumes.
Examples:

The following table provides some examples of file masks that can be used on the Inclusions tab of the auditing wizard. Note that <String> in this table may contain any of the file mask characters described above (i.e., fixed characters, * or ?).
