This enables resource managers to enforce access control in the following ways: Shared resources use access control lists (ACLs) to assign permissions. Objects include files, folders, printers, registry keys, and Active Directory Domain Services (AD DS) objects. Security principals perform actions (which include Read, Write, Modify, or Full control) on objects. During the access control check, these permissions are examined to determine which security principals can access the resource and how they can access it. Each resource has an owner who grants permissions to security principals. They are assigned rights and permissions that inform the operating system what each user and group can do. In the access control model, users and groups (also referred to as security principals) are represented by unique security identifiers (SIDs). Shared resources are available to users and groups other than the resource's owner, and they need to be protected from unauthorized use. After a user is authenticated, the Windows operating system uses built-in authorization and access control technologies to implement the second phase of protecting resources: determining if an authenticated user has the correct permissions to access a resource. Feature descriptionĬomputers that are running a supported version of Windows can control the use of system and network resources through the interrelated mechanisms of authentication and authorization. Key concepts that make up access control are permissions, ownership of objects, inheritance of permissions, user rights, and object auditing. This topic for the IT professional describes access control in Windows, which is the process of authorizing users, groups, and computers to access objects on the network or computer.
