Active Directory, or AD as it less formerly known, is essentially a directory
service that was developed by Microsoft for Windows domain networks.
When it was first created, the software was solely responsible for centralised domain management, but it soon became an umbrella term for a wide range of directory-based and identity-related services.
The software authenticates and authorises all users and computers that
utilise a Windows doain type network, while assigning and enforcing
adequate security policies for systems installing or updating the programme.
For example, when logging into a computer that is part of a Windows
domain, Active Directory checks the password and determines the level of authority of the user. It also enables and manages the storage of information providing authorisation mechanisms that are key in the age where cyber security is of upmost importance. Knowledge of this software is beneficial for anyone wishing to work in the IT field.
