Which function does Active Directory serve in a network?

Active Directory serves a crucial role within a network by managing permissions and access to networked resources. It is a directory service developed by Microsoft for Windows domain networks, which allows administrators to create and manage users, computers, and other devices in a centralized manner.

The primary function of Active Directory focuses on identity and access management; it stores information about members of the domain, including devices and users, and enforces security policies across the network. This means that when a user attempts to access a resource, Active Directory checks their credentials against its directory and determines whether they have the appropriate permissions to gain access. This capability is essential for maintaining the security and integrity of the network, ensuring that only authorized users can access sensitive information and systems.

This focus on managing permissions and access also extends to managing group policies, which can define the settings and restrictions applied at an organizational level, further enhancing security and streamline user experiences. In a multi-user and multi-device environment, this helps ensure that applications, files, and resources are appropriately secured and managed.
