Microsoft Sentinel audit tables reference

  • Стаття

This article describes the fields in the SentinelAudit tables, which are used for auditing user activity in Microsoft Sentinel resources. With the Microsoft Sentinel audit feature, you can keep tabs on the actions taken in your SIEM and get information on any changes made to your environment and the users that made those changes.

Learn how to query and use the audit table for deeper monitoring and visibility of actions in your environment.

Important

The SentinelAudit data table is currently in PREVIEW. See the Supplemental Terms of Use for Microsoft Azure Previews for additional legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.

Microsoft Sentinel's audit feature currently covers only the analytics rule resource type, though other types may be added later. Many of the data fields in the following tables will apply across resource types, but some have specific applications for each type. The descriptions below will indicate one way or the other.
