Introducing Quest Security Guardian Using the Dashboard Tier Zero Objects Assessments Findings Security Settings Appendix - Security Guardian Indicator Details

Configuring a Forwarding Destination

 

If your organization uses Microsoft Sentinel and/or Splunk (Cloud Platform or Enterprise) as a SIEM solution, you can configure Security Guardian to forward Findings to the applicable tool for further analysis.

You can also configure email alerts for Findings, as well as for the first completed assessment.

 

Once configured, the tile for the forwarding destination shows details of the configuration, as well as when the last Finding was sent. A forwarding destination can also be edited or removed.

 

To access the Forwarding configuration page:

  1. From the On Demand left navigation menu, choose Security | Settings.

  2. Make sure the Forwarding tab is selected.

To configure Microsoft Sentinel as a forwarding destination:

  1. Click Add Forwarding Destination, select Microsoft Sentinel.

  2. Enter the Sentinel Workspace ID and Shared (Primary) Key.

    Refer to the Microsoft documentation for instructions on Finding the Workspace ID and key.

  3. Click Send Test Event to ensure that a connection can be made to Sentinel.

    A message will be returned indicating whether or not the test event was successfully sent. If the test event was not successful, ensure the Workspace ID and Shared Key were entered correctly.

  4. Click Save.

To configure Splunk (Cloud Platform or Enterprise) as a forwarding destination:

  1. Click Add Forwarding Destination, select Splunk.

  2. Enter the Splunk HTTP Event Collector URL (e.g. <http or https>://<cloud or server address>:<port>) and Token.

    Refer to the Splunk documentation for instructions on Finding the HTTP Event Collector URL and Token.

  3. Click Send Test Event to ensure that a connection can be made to Splunk.

    A message will be returned indicating whether or not the test event was successfully sent. If the test event was not successful, ensure the URL and Token were entered correctly.

  4. Click Save.

To configure Email as a forwarding destination:

  1. Click Add Forwarding Destination, select Email.

  2. Add the Forward To email recipients that you want alerts sent to. If you are entering multiple email addresses, separate each with a semicolon.

  3. Click Save.

Managing Indicators

  • Tier Zero object activity
  • The following exposures and compromises:
    • Security Assessment vulnerabilities detected by Security Guardian
    • Critical Activity and unprotected Tier Zero objects collected by On Demand Audit.

NOTE: Indicator-specific detail, with listings by severity and by the data source, can be found in the Appendix.

 

If you no longer want a Finding to be generated for an indicator, you can mute it.

EXCEPTION: New Tier Zero object indicators cannot be muted.
