Win32_LogicalFileSecuritySetting class

  • [アーティクル]

The Win32_LogicalFileSecuritySetting WMI class represents security settings for a logical file. You cannot enumerate instances of this class.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Members

The Win32_LogicalFileSecuritySetting class has these types of members:

Methods

The Win32_LogicalFileSecuritySetting class has these methods.

Method Description
GetSecurityDescriptor Class method that retrieves a structural representation of the object security descriptor (SD).
SetSecurityDescriptor Class method that sets an SD to the specified structure.

Properties

The Win32_LogicalFileSecuritySetting class has these properties.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

Short textual description of the CIM_Setting object.

This property is inherited from CIM_Setting.

ControlFlags

Data type: uint32

Access type: Read-only

Control bits that qualify the meaning of an SD or its individual members. For more information about how to set the ControlFlags value, see the Remarks section. The following list lists the flags in ControlFlags. For more information, see SECURITY_DESCRIPTOR_CONTROL.

This property is inherited from Win32_SecuritySetting.

SE_OWNER_DEFAULTED (1 (0x1))

Indicates an SD with a default owner security identifier (SID). You can use this bit to find all of the objects that have default owner permissions set.

SE_GROUP_DEFAULTED (2 (0x2))

Indicates an SD with a default group SID. You can use this bit to find all of the objects that have default group permissions set.

SE_DACL_PRESENT (4 (0x4))

Indicates an SD that has a discretionary access control list (DACL). If this flag is not set, or if this flag is set and the DACL is NULL, the SD allows full access to everyone.

SE_DACL_DEFAULTED (8 (0x8))

Indicates an SD with a default DACL. For example, if an object creator does not specify a DACL, the object receives the default DACL from the access token of the creator. This flag can affect how the system treats the DACL, with respect to access control entry (ACE) inheritance. The system ignores this flag if the SE_DACL_PRESENT flag is not set.

SE_SACL_PRESENT (16 (0x10))

Indicates an SD that has a system access control list (SACL).

SE_SACL_DEFAULTED (32 (0x20))

Indicates an SD with a default SACL. For example, if an object creator does not specify an SACL, the object receives the default SACL from the access token of the creator. This flag can affect how the system treats the SACL, with respect to ACE inheritance. The system ignores this flag if the SE_SACL_PRESENT flag is not set.

SE_DACL_AUTO_INHERIT_REQ (256 (0x100))

Requests that the provider for the object protected by the SD automatically propagate the DACL to existing child objects. If the provider supports automatic inheritance, it propagates the DACL to any existing child objects, and sets the SE_DACL_AUTO_INHERITED bit in the security descriptors of the object and its child objects.

SE_SACL_AUTO_INHERIT_REQ (512 (0x200))

Requests that the provider for the object protected by the SD automatically propagate the SACL to existing child objects. If the provider supports automatic inheritance, it propagates the SACL to any existing child objects, and sets the SE_SACL_AUTO_INHERITED bit in the SDs of the object and its child objects.

SE_DACL_AUTO_INHERITED (1024 (0x400))

Windows 2000 only. Indicates an SD in which the DACL is set up to support automatic propagation of inheritable ACEs to existing child objects. The system sets this bit when it performs the automatic inheritance algorithm for the object and its existing child objects. This bit is not set in SDs for Windows NT versions 4.0 and earlier, which do not support automatic propagation of inheritable ACEs.

SE_SACL_AUTO_INHERITED (2048 (0x800))

Windows 2000: Indicates an SD in which the SACL is set up to support automatic propagation of inheritable ACEs to existing child objects. The system sets this bit when it performs the automatic inheritance algorithm for the object and its existing child objects. This bit is not set in SDs for Windows NT versions 4.0 and earlier, which do not support automatic propagation of inheritable ACEs.

SE_DACL_PROTECTED (4096 (0x1000))

Windows 2000: Prevents the DACL of the SD from being modified by inheritable ACEs.

SE_SACL_PROTECTED (8192 (0x2000))

Windows 2000: Prevents the SACL of the SD from being modified by inheritable ACEs.

SE_SELF_RELATIVE (32768 (0x8000))

Indicates an SD in self-relative format with all of the security information in a contiguous block of memory. If this flag is not set, the SD is in absolute format. For more information, see Absolute and Self-Relative Security Descriptors.

Description

Data type: string

Access type: Read-only

Textual description of the CIM_Setting object.

This property is inherited from CIM_Setting.

OwnerPermissions

Data type: boolean

Access type: Read-only

Owner permissions to the object.

Path

Data type: string

Access type: Read-only

Qualifiers: key

Full path of the file or directory.

SettingID

Data type: string

Access type: Read-only

Qualifiers: MaxLen (256)

Identifier by which the CIM_Setting object is known.

This property is inherited from CIM_Setting.

Remarks

The Win32_LogicalFileSecuritySetting class is derived from Win32_SecuritySetting.

The ControlFlags property contains individual bit positions that identify the specific flags that are set. You can combine the flags by adding the associated values. For example, to specify both SE_DACL_PRESENT and SE_DACL_AUTO_INHERITED you add the associated values 4 and 1024 to make the value of the ControlFlags property 1028.

If the SE_DACL_PRESENT bit is specified and a DACL entry is also present in the call to SetSecurityDescriptor, an empty DACL is written out. If the SE_DACL_PRESENT bit is not set in the control flags, but a DACL is specified as being written out, none will be. Conversely, if SE_DACL_PRESENT bit is set, but no actual DACL parameter is set when calling SetSecurityDescriptor, a NULL DACL is written out.

Note

A NULL DACL creates a security risk because it gives full access to everyone. For more information, see Creating a DACL.

If the SeSecurityPrivilege is not granted or enabled, then the SACL is not returned. For more information, see Privilege Constants and Executing Privileged Operations.

Examples

The following VBScript code example obtains a Win32_LogicalFileSecuritySetting instance for file C:\Temp on the local computer.

strComputer = "." 
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") 

Set colItems = objWMIService.ExecQuery( _
    "SELECT * FROM Win32_LogicalFileSecuritySetting WHERE Path=""c:\\Temp""",,48) 
For Each objItem in colItems 
    Wscript.Echo "Win32_LogicalFileSecuritySetting for file c:\Temp"
    Wscript.Echo "ControlFlags: " & objItem.ControlFlags
    Wscript.Echo "Description: " & objItem.Description
    Wscript.Echo "OwnerPermissions: " & objItem.OwnerPermissions
    Wscript.Echo "Path: " & objItem.Path
    Wscript.Echo "SettingID: " & objItem.SettingID
