What is Active Directory Anyway?

Alright, before we get into the nitty-gritty, let's make sure we're all on the same page. Active Directory (AD) is essentially a directory service developed by Microsoft for Windows domain networks. Think of it as a central database that stores information about all the users, computers, and other resources within a network. This database is organized in a hierarchical structure, making it easy to manage and control access to different resources. It’s like a giant phone book for your company's digital world, making sure everyone can find and connect to what they need. It’s a core component of Windows Server and is used by businesses of all sizes to manage their IT infrastructure. Active Directory allows IT administrators to manage users, computers, and other resources from a central location. It provides a single point of authentication and authorization, simplifying the management of user accounts and access to resources. This central management capability is one of the key active directory advantages. With AD, you can control access to files, printers, and applications, enforce security policies, and deploy software across your network. It streamlines a lot of IT tasks, making life easier for IT professionals and improving the overall efficiency of the organization. AD uses a database called the Active Directory Database (also known as the Directory Information Tree or DIT) to store information. The database is stored on one or more domain controllers, which are servers that hold a copy of the AD database. When a user logs in to a computer that is part of a domain, the computer contacts a domain controller to authenticate the user's credentials. If the credentials are valid, the user is granted access to the network resources that they are authorized to use. The design of Active Directory is based on the Lightweight Directory Access Protocol (LDAP), which allows applications to access and modify directory information. AD also supports other protocols, such as Kerberos for authentication and DNS for name resolution. Furthermore, Active Directory employs a robust security model to protect the integrity of the directory data and prevent unauthorized access. This includes features like password policies, access control lists (ACLs), and auditing capabilities, which contribute to the security of the network environment. It can be used to manage everything from user accounts and passwords to security policies and software deployments. AD is more than just a directory; it's a comprehensive management system that helps organizations maintain control over their IT resources. And hey, it's not all rainbows and sunshine. There are also active directory disadvantages that we'll explore later on.
