Kaspersky Embedded Systems Security 3.4 for Windows

Configuring SIEM integration settings

To reduce the load on low-performance devices and to reduce the risk of system degradation as a result of increased application log sizes, you can configure the publication of audit events and task performance events to the syslog server via the Syslog protocol.

A syslog server is an external server for aggregating events (SIEM). It stores and analyzes received events and performs other log management actions.

You can use SIEM integration in two modes:

• Duplicate events on the syslog server: in this mode, all task performance events whose publication is configured in log settings, as well as all system audit events, continue to be stored on the protected device even after they are sent to the SIEM server.

  We recommend that you use this mode to reduce the load on the protected device as much as possible.

• Delete local copies of events: in this mode, all events that are registered during application operation and published to the SIEM server will be deleted from the protected device.

  The application never deletes local versions of the security log.

Kaspersky Embedded Systems Security for Windows can convert events in application logs into formats supported by the syslog server so that those events can be transmitted and successfully recognized by the SIEM server. The application supports conversion into structured data format and into JSON format.

You can reduce the risk that events will be relayed to the SIEM server unsuccessfully by defining the settings for connecting to a mirror syslog server.

A mirror syslog server is an additional syslog server to which the application switches automatically if the connection to the main syslog server is unavailable or if the main server cannot be used.

By default, SIEM integration is not used. You can enable and disable SIEM integration, and configure relevant settings (see the table below).

SIEM integration settings

To configure the settings for integration with SIEM:

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 log settings for a group of protected devices, select the Policies tab and open the Properties: <Policy name> window.
   • To configure the application for an individual protected device, select the Devices tab and go to the application settings.
4. In the Logs and notifications section, click the Task logs button in the Settings subsection.

   The Logs and notifications settings window opens.

5. Select the SIEM integration tab.
6. In the Integration settings block, select the
   Send events to a remote syslog server via syslog protocol

   

   The check box enables or disables the functionality for sending published events to an external syslog server.

   If the check box is selected, the application sends published events to the SIEM server according to the configured SIEM integration settings.

   If the check box is cleared, the application does not perform SIEM integration. You cannot configure SIEM integration settings if the check box is cleared.

   By default, the check box is cleared.

   check box.
7. If necessary, in the Integration settings block, select the
   Remove local copies for events that have been sent to a remote syslog server

   

   The check box enables or disables deletion of local copies of logs when they are sent to the SIEM server.

   If the check box is selected, the application deletes the local copies of events after they have been successfully published to the SIEM server. This mode is recommended on low-performance devices.

   If the check box is cleared, the application only sends events to the SIEM server. Copies of logs continue to be stored locally.

   By default, the check box is cleared.

   check box.

   The status of the Remove local copies for events that have been sent to a remote syslog server check box does not affect the settings for storing events of the security log: the application never automatically deletes security log events.

8. In the Events format block, specify the format to which you want to convert application events so that they can be sent to the SIEM server.

   By default, the application converts them into a structured data format.

9. In the Connection settings block:
   • Specify the SIEM connection protocol.
   • In the fields of the same name, specify the IPv4 address and port for connecting to the main syslog server.
   • Select the Use mirror syslog server if the main server is not accessible check box if you want the application to use other connection settings when unable to send events to the main syslog server.
   • In the fields of the same name, specify the IPv4 address and port for connecting to an additional syslog server.
10. Click the OK button.

The configured SIEM integration settings will be applied.
