2.4.4.12 SYSTEM_AUDIT_CALLBACK_ACE
The SYSTEM_AUDIT_CALLBACK_ACE structure defines an ACE for the SACL that specifies what types of access cause system-level notifications. A system-audit ACE causes an audit message to be logged when a specified trustee attempts to gain access to an object. The trustee is identified by a SID.

Header (4 bytes): An ACE_HEADER structure that specifies the size and type of ACE. It also contains flags that control inheritance of the ACE by child objects.
Mask (4 bytes): An ACCESS_MASK structure that specifies the user rights that cause audit messages to be generated.
Sid (variable): The SID of a trustee. The length of the SID MUST be a multiple of 4. An access attempt of a kind specified by the Mask field by any trustee whose SID matches the Sid field causes the system to generate an audit message. If an application does not specify a SID for this field, audit messages are generated for the specified access rights for all trustees.
ApplicationData (variable): Optional application data. The size of the application data is determined by the AceSize field of the ACE_HEADER.
