Access Mask Format

Access Mask Format

All securable objects arrange their access rights by using the access mask format shown in the following illustration.

Access mask format

In this format, the low-order 16 bits are for object-specific access rights, the next 8 bits are for standard access rights, which apply to most types of objects, and the 4 high-order bits are used to specify generic access rights that each object type can map to a set of standard and object-specific rights. The ACCESS_SYSTEM_SECURITY bit corresponds to the right to access the object's SACL.
