Configuring the KSN Usage task

To configure the KSN Usage task:

1. Expand the Managed devices node in the Kaspersky Security Center Administration Console tree.
2. Select the administration group for which you want to configure application settings.
3. Perform one of the following actions in the details pane of the selected administration group:
   • To configure application settings for a group of protected devices, select the Policies tab and open the Properties: <Policy name> window.
   • To configure the application for a single protected device, select the Devices tab and open the Application settings window.

     If an active Kaspersky Security Center policy is applied to a device and blocks changes to application settings, then these settings cannot be edited in the Application settings window.

4. In the Real-time Server Protection section, click the Settings button in the KSN Usage subsection.

   The KSN Usage window opens.

5. On the General tab, configure the following task settings:
   • In the Action to perform on KSN untrusted objects section, specify the action that Kaspersky Security for Windows Server is to perform if it detects an object identified by KSN as untrusted:
     • Remove
       

       Kaspersky Security for Windows Server deletes the object with KSN-untrusted status and places a copy of it in Backup.

       This option is selected by default.

     • Log information
       

       Kaspersky Security for Windows Server records information about the object with KSN-untrusted status in the task log. Kaspersky Security for Windows Server does not delete the untrusted object.

   • In the Data transfer section, restrict the size of files for which the checksum is calculated:
     • Clear or select the Do not calculate checksum before sending to KSN if file size exceeds (MB) check box.
       

       This check box enables or disables calculation of the checksum for files of the specified size for delivery of this information to the KSN service.

       The duration of the checksum calculation depends on the file size.

       If this check box is selected, Kaspersky Security for Windows Server does not calculate the checksum for files that exceed the specified size (in MB).

       If the check box is cleared, Kaspersky Security for Windows Server calculates the checksum for files of any size.

       The check box is selected by default.

     • If required, in the field to the right, change the maximum size of files for which Kaspersky Security for Windows Server calculates the checksum.
   • In the KSN Proxy section, clear or select the Use Kaspersky Security Center as KSN Proxy check box.
     

     The check box allows to manage the data transfer between the protected devices and KSN.

     If the check box is cleared the data from the Administration Server and protected devices is sent to KSN directly (not via the Kaspersky Security Center). The active policy defines which type of data can be sent to KSN directly.

     If the check box is selected, all data is sent to KSN via the Kaspersky Security Center.

     The check box is selected by default.

     To enable KSN Proxy the KSN Statement must be accepted and Kaspersky Security Center properly configured. See Kaspersky Security Center Help for more details.

6. If needed, configure the task start schedule on the Task management tab. For example, you can start the task by schedule and specify the At application launch frequency, if you want the task to run automatically when the protected device is restarted.

   The application will automatically start the KSN Usage task by schedule.

7. Configure the data handling before starting the task.
8. Click OK.

The modified settings are applied. The date and time of modifying the settings, as well as information about the task settings before and after modification, are saved in the system audit log.
