This process takes place with the generation of security tokens checked against a predefined set of rules unique to each user.Īuthentication and authorization form the basis of identity and access management. Something you are, like a fingerprint or other biometricĪuthorization: Authorization is the other core functionality of AD, which successively follows the authentication process. Access and permissions to use appropriate network resources and other relevant data are granted to users through authorization. Something you have, like a soft token or a smart card Something you know, like an email address, or a username and password combination The process of checking identities in very definitive terms forms the basis of the authentication process. Identities can be authenticated through any of the following three ways:
Now, let us look at two of the most fundamental processes of an AD environment:Īuthentication: Authentication is one of the core functionalities of AD through which the identity of any user that logs on to an AD domain is checked and access is either allowed or denied. The DC has complete domain authority and controls the authentication and modifications to all network resources contained within its domain. A Windows environment that has a DC with AD DS installed and functioning as the central authenticating and authorizing node is called a domain-controlled environment.ĪD follows a client-server architecture with the DC being the central server that services the other connected network resources in the domain. All these domain objects may share the same central domain controller (DC). Grouping network resources logically to form an AD domain is done by the administrator. AD also allows administrators to define security policies that govern who has access to what in the network. Unlike in a workgroup where network administrators have to individually identify and manage policies and permissions manually, AD provides a central database that facilitates administrators to set up appropriate access controls and permissions to use various network resources.
AD is set up to centrally configure, group together, and manage a logical collection of network resources in an AD domain. In order to ensure the effective management of these resources, IT administrators use AD and its components, including AD DS. It is the core component and a server role in Active Directory (AD), the specialized, proprietary directory service in Windows operating system environments.Ĭonsider an enterprise or a complex business set up with many connected network resources. Active Directory Domain Services (AD DS) is the traditional, on-premises domain service offered by Microsoft.
