What is active directory and how it works

Active Directory (AD) is a directory service developed and designed by Microsoft for Windows-based networks. It stores and centrally manages user data, applications, services, and security policies to control data access throughout a network.

Components of Active Directory #

Active Directory consists of two main components – The Domain Name System (DNS) and The Lightweight Directory Access Protocol (LDAP).

  • DNS: This is a distributed and hierarchical name resolution service used for accessing resources on a network.
  • LDAP: This is an application protocol in which a client can access and change information stored in the Directory.

Active Directory Services #

Active Directory provides several built-in services designed to help administrators manage and secure their networks. These services include single sign-on authentication, group policy management, and security and auditing capabilities.

How Do Active Directory Services Work? #

Active Directory services are primarily used for authentication and authorization. When a user attempts to log into a computer, Active Directory will authenticate their credentials against the user data stored in the directory. Once the user is authenticated, Active Directory will determine if they have been assigned the correct access rights and authorization to access the resources on the network. This process ensures that only authenticated and authorized users are allowed access.

Conclusion #

Active Directory is an essential part of any Windows-based network, providing administrators with the ability to securely manage and control access to resources on the network. By utilizing the built-in services such as single sign-on authentication, group policy management, and security and auditing capabilities, Active Directory can help ensure that only authenticated and authorized users are allowed access to resources on the network.
