The __SystemEvent class has these properties.
-
SECURITY_DESCRIPTOR
-
-
Data type: uint8 array
-
Access type: Read-only
Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event.

A NULL Access Control List (ACL) in the SECURITY_DESCRIPTOR grants unlimited access to everyone all the time. For more information, see Creating a Security Descriptor for a New Object.

Data type: uint64
-

For more information about using uint64 values in scripts, see Scripting in WMI.
