SECURITY_QUALITY_OF_SERVICE
The SECURITY_QUALITY_OF_SERVICE data structure contains information used to support client impersonation. A
client can specify this information when it connects to a server; the
information determines whether or not the server may impersonate the client, and if so,
to what extent.
typedef struct _SECURITY_QUALITY_OF_SERVICE { // sqos
DWORD Length;
SECURITY_IMPERSONATION_LEVEL ImpersonationLevel;
SECURITY_CONTEXT_TRACKING_MODE ContextTrackingMode;
BOOLEAN EffectiveOnly;
} SECURITY_QUALITY_OF_SERVICE;
Members
Length
Specifies the size, in bytes, of this structure.
ImpersonationLevel
Specifies what the server may be told about the client, and how the server may
represent, or impersonate, the client. Security impersonation levels govern
the degree to which a server process can act on behalf of a client process. This
member is a SECURITY_IMPERSONATION_LEVEL enumeration type value.
ContextTrackingMode
Specifies whether the server is to be given a snapshot of the client's
security context (called static tracking), or is to be continually updated to track
changes to the client's security context (called dynamic tracking). The value
SECURITY_STATIC_TRACKING specifies static tracking, and the value
SECURITY_DYNAMIC_TRACKING specifies dynamic tracking. Not all communications mechanisms support
dynamic tracking; those that do not will default to static tracking.
EffectiveOnly
Specifies whether or not the server may enable or disable privileges and
groups that the client's security context may include.
