After installing the latest Windows updates, my Event Log (Windows API) sensors do not work with error messages:
"Access Denied, Code:5, or 1314 a required privilege is not held by the client."
Workaround for the Event Log (Windows API) sensor issue
Event Log (Windows API) sensors might not work anymore after Windows updates of June 2021 because of security hardening changes for the Event Tracing for Windows (ETW) that relate to the security vulnerability issue CVE-2021-31958. For more information on this issue, see https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-31958.
The Event Log (Windows API) sensor will be deprecated. Please use the WMI Event Log sensor instead, which provides the same functionalities.
