SetServiceObjectSecurity info  Overview  Group

The SetServiceObjectSecurity function sets the security descriptor of a service object.

BOOL SetServiceObjectSecurity(

Parameters

hService

Identifies the service. This handle is returned by the OpenService or CreateService function. The access required for this handle depends on the security information specified in the dwSecurityInformation parameter.

dwSecurityInformation

Specifies the security information to be set. Any or all of the following flags can be specified:

Value	Meaning
OWNER_SECURITY_INFORMATION	Sets the object’s owner security identifier (SID). The hService handle must have WRITE_OWNER access, or the calling process must be the object’s owner.
GROUP_SECURITY_INFORMATION	Sets the object’s primary group SID. The hService handle must have WRITE_OWNER access, or the calling process must be the object’s owner.
DACL_SECURITY_INFORMATION	Sets the object’s discretionary access control list (ACL). The hService handle must have WRITE_DAC access, or the calling process must be the object’s owner.
SACL_SECURITY_INFORMATION	Sets the object’s system ACL. The calling process must have the SE_SECURITY_NAME privilege. For more information about security privileges, see Privileges.

lpSecurityDescriptor

Points to a SECURITY_DESCRIPTOR structure containing the new security information.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Errors

The following error codes can be set by the service control manager. Other error codes can be set by the registry functions that are called by the service control manager.

Remarks

The SetServiceObjectSecurity function sets the specified portions of the service object’s security descriptor, based on the information specified in the lpSecurityDescriptor buffer. This function replaces any or all of the security information associated with the service object, according to the flags set in the dwSecurityInformation parameter and subject to the calling process’s access rights.

The initial security descriptor of a service object is created by the service control manager, based on the security descriptor of the process that called the CreateService function to create the service. You can change the security descriptor by calling the SetServiceObjectSecurity function.
