SECURITY_DESCRIPTOR info  Overview  Group

The SECURITY_DESCRIPTOR structure contains the security information associated with an object. Applications use this structure to set and query an object’s security status.

Applications are not to modify the SECURITY_DESCRIPTOR structure directly. For creating and manipulating a security descriptor, use the functions listed in the See Also section.

typedef PVOID PSECURITY_DESCRIPTOR; 

 

Remarks

A security descriptor includes information that specifies the following components of an object’s security:

• An owner (SID)

• A primary group (SID)

• A discretionary ACL

• A system ACL

• Qualifiers for the preceding items

Security descriptors use access-control lists (ACLs) and security identifiers (SIDs) to specify the information in this list.

A security descriptor can be in absolute or self-relative form. In self-relative form, all members of the structure are located contiguously in memory. In absolute form, the structure only contains pointers to the members.
