Limitations

When you upgrade to Splunk Enterprise Security version 7.1.x, contributing risk events for risk notables might not be visible in the Risk Event Timeline if the risk notables are created before the upgrade and any one of the following conditions are met:

  • CIM entity zones are enabled
  • Changes are made to the CIM entity zones that apply to existing risk notables
  • Asset and identity framework is disabled

For more information, see After upgrading to Splunk Enterprise Security Version 7.1.0.

Additionally, if you make changes to the CIM entity zones or the assets and identity framework, you might cause a change to the risk object normalization, which might result in contributing risk events not being visible in the Risk Event Timeline visualization. This pertains to risk notables that were created prior to making the changes to the CIM entity zones and assets and identity framework.
