Windows Server 2008 File Classification Rules

Once the file administrator has created the necessary file classification properties, they can proceed in creating classification rules that will actually process and classify the files that meet the rule criteria, by applying the necessary classification property values to the file collections. To create a new classification rule, perform the following steps:

1. Log on to the same Windows Server 2008 R2 system that the Files with Passwords classification property was previously defined on, with an account with administrative rights.

2. Click Start, click All Programs, click Administrative Tools, and select Server Manager.

3. Expand Roles, expand File Services, expand Share and Storage Management, and double-click on the File Server Resource Manager node beneath it.

4. Double-click Classification Management and select the Classification Rules node.

5. In the Actions pane, click on the Create a New Rule link to start the creation of a new classification rule.

6. In the Classifications Rule Definitions window, type in the name of the rule as Classify files with passwords and enter a description.

7. In the Scope section of the page, click the Add button to define the volumes and or folders that this classification rule will be applied to. For our example, we will apply this rule to E:\ITDept. When the location is specified, all subfolders will be included.

8. Once the name, description, and file locations are defined, click on the Classification tab and select Content Classifier from the Classification mechanism drop-down menu.

9. In the Property Name section, select the Files with Passwords property and set the property value to be assigned as Yes.

10. Click the Advanced button to set the additional parameters that will actually be used to determine if the files match the criteria and should be classified with the property defined in this rule.

11. In the Additional Rule Parameters window, select the Additional Classification Parameters tab. On this tab, administrators can define three different types of criteria used to search with a files content. These three types are as follows:

» RegularExpression—The RegularExpression is the same as is used with .NET programming and can be used to find complex or multiple types of data formats, for more complex searches.

» String—The String type is used to find a very specific string, such as password that will not be dependent on the case of the string, although the string must be an exact match. For example, the string password will not match passwords, as that is a different string.

» StringCaseSensitive—The StringCaseSensitive is the same as the string, in that the entire string must be an exact match, but the case must match. For example, the StringCaseSensitive string of Password will not match the string password.

12. For our example, we will specifically look for the word password and will not care about the case. In the Name section, type in String and in the value type in password. Click OK when completed.

13. Back on the Classification Rule Definitions page, click OK to complete the rule creation.

Once the rule is created, it can be scheduled or run manually. To run all of the rules manually, in the tasks pane, right-click on the Classification Rules node and select Run Classification with All Rules Now. Follow the steps to select the type of report that will be generated and whether the administrator will wait for the classification to complete and display the window or to have the process run in the background. If a schedule or a manual run is performed, any files that meet the properties of any enabled classification rules will be classified, unless these files have been previously classified.
