Security descriptors are data structures of security information for ''securable'' Windows objects, that is objects that can be identified by a unique name. Security descriptors can be associated with any named objects, including files, folders, shares, registry keys, processes, threads, named pipes, services, job objects and other resources. Security descriptors contain discretionary access control lists (DACLs) that contain access control entries (ACEs) that grant and deny access to trustees such as users or groups. They also contain a system access control list (SACLs) that control auditing of object access.〔(【引用サイトリンク】title=What Are Security Descriptors and Access Control Lists? )〕 ACEs may be explicitly applied to an object or inherited from a parent object. The order of ACEs in an ACL is important, with access denied ACEs appearing higher in the order than ACEs that grant access. Security descriptors also contain the object owner. Mandatory Integrity Control is implemented through a new type of ACE on a security descriptor.〔https://msdn.microsoft.com/en-us/library/bb625957.aspx What is the Windows Integrity Mechanism?〕 Files and folder permissions can be edited by various tools including Windows Explorer, WMI, command line tools like Cacls, XCacls, ICacls, SubInACL,〔(SubInACL home page )〕 the freeware Win32 console FILEACL,〔(FILEACL home page )〕〔 〕 the free software utility SetACL, and other utilities. To edit a security descriptor, a user needs WRITE_DAC permissions to the object, a permission that is usually delegated by default to administrators and the object's owner. ==See also== * * Information technology security audit * Authorization * Computer security * Information security * Token (Windows NT architecture) * Windows SID * SDDL 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Security descriptor」の詳細全文を読む スポンサード リンク
