description: The search looks for modifications to registry keys that control the
|
|
enforcement of Windows User Account Control (UAC).
|
|
how_to_implement: To successfully implement this search, you must be ingesting data
|
|
that records registry activity from your hosts to populate the endpoint data model
|
|
in the registry node. This is typically populated via endpoint detection-and-response
|
|
products, such as Carbon Black, or via other endpoint data sources, such as Sysmon.
|
|
The data used for this search is typically generated via logs that report registry
|
|
modifications.

a change in system policy. This type of change should be a very rare occurrence.
