Organizations of all sizes all over the world use Active Directory to help manage permissions and control access to critical network resources. But what exactly is it, and how can it potentially help your business? Active Directory (AD) is a directory service that runs on Microsoft Windows Server. The main function of Active Directory is to enable administrators to manage permissions and control access to network resources. In Active Directory, data is stored as objects, which include users, groups, applications, and devices, and these objects are categorized according to their name and attributes. Active Directory Domain Services (AD DS) are a core component of Active Directory and provide the primary mechanism for authenticating users and determining which network resources they can access. AD DS also provides additional features such as Single Sign-On (SSO), security certificates, LDAP, and access rights management. AD DS organizes data in a hierarchical structure consisting of domains, trees, and forests, as detailed below. Domains: A domain represents a group of objects such as users, groups, and devices, which share the same AD database. You can think of a domain as a branch in a tree. A domain has the same structure as standard domains and sub-domains, e.g. yourdomain.com and sales.yourdomain.com. Trees: A tree is one or more domains grouped together in a logical hierarchy. Since domains in a tree are related, they are said to “trust” each other. Forest: A forest is the highest level of organization within AD and contains a group of trees. The trees in a forest can also trust each other, and will also share directory schemas, catalogs, application information, and domain configurations. Organizational Units: An OU is used to organize users, groups, computers, and other organizational units. Containers: A container is similar to an OU, however, unlike an OU, it is not possible to link a Group Policy Object (GPO) to a generic Active Directory container. Besides Active Directory Domain Services, there are a handful of other critical services that AD provides. Some of those services have been listed below: Lightweight Directory Services: AD LDS is a Lightweight Directory Access Protocol (LDAP) directory service. It provides only a subset of the AD DS features, which makes it more versatile in terms of where it can be run. For example, it can be run as a stand-alone directory service without needing to be integrated with a full implementation of Active Directory. Certificate Services: You can create, manage and share encryption certificates, which allow users to exchange information securely over the internet. Active Directory Federation Services: ADFS is a Single Sign-On (SSO) solution for AD which allows employees to access multiple applications with a single set of credentials, thus simplifying the user experience. Rights Management Services: AD RMS is a set of tools that assists with the management of security technologies that will help organizations keep their data secure. Such technologies include encryption, certificates, and authentication, and cover a range of applications and content types, such as emails and Word documents. The server that hosts AD DS is called a domain controller (DC). A domain controller can also be used to authenticate with other MS products, such as Exchange Server, SharePoint Server, SQL Server, File Server, and more. A comprehensive step-by-step guide to setting up Active Directory on Windows Server is beyond the scope of this article. Instead, I will provide a basic summary of the steps required to install AD, which should at least point you in the right direction. Assuming you already have Windows Server (2016) installed, you will need to…
Once you have Active Directory Domain Services installed, you will then need to configure your installation, which includes changing default passwords, setting up OUs, domains, trees, and forests. As mentioned, a detailed explanation of setting up and configuring Active Directory is beyond the scope of this article. For detailed up-to-date instructions, you will need to consult the official documentation. Given that increasingly more organizations are shifting their business operations to the cloud, Microsoft has introduced Azure Active Directory (Azure AD), which is their cloud-based version of Windows AD, which can also sync with on-premise AD implementations. Azure AD is said to be the backbone of Office 365 and other Azure products; however, it can also be integrated with other cloud services and platforms. Some of the differences between Windows and Azure AD are as follows. Communication: Azure AD uses a REST API, whereas Windows AD uses LDAP, as mentioned previously. Authentication: Windows AD uses Kerberos and NTLM for authentication, whereas Azure AD uses its own built-in web-based authentication protocols. Structure: Unlike Windows AD, which is organized by OUs, trees, forests, and domains, Azure AD uses a flat structure of users and groups. Device Management: Unlike Windows AD, Azure AD can be managed via mobile devices. Azure AD does not rely on Group Policy Objects (GPOs) to determine which devices and servers are able to connect to the network. If you are reading an article about Active Directory, it’s more than likely that you are not already using it. In which case, you might be better off starting with Azure AD as opposed to Windows AD. One of the main reasons why you might want to use Windows AD is if you are storing large amounts of valuable data and have a team of experienced IT professionals managing your cybersecurity program.

Active Directory (AD) is a database and set of services that connect users with the network resources they need to get their work done. The database (or directory) contains critical information about your environment, including what users and computers there are and whos allowed to do what. Which Active Directory component has a central security database that is used by all computers that are members of it?Which Active Directory component has a central security database that is used by all computers that are members of it? Domain controllers download Group Policy settings every five minutes. What is the Active Directory?Active Directory (AD) is Microsofts proprietary directory service. It runs on Windows Server and enables administrators to manage permissions and access to network resources. Active Directory stores data as objects. An object is a single element, such as a user, group, application or device such as a printer. Is Active Directory a distributed database?AD DS is a distributed database that stores and manages information about network resources as well as application-specific data from directory-enabled applications. AD DS allows administrators to organize elements of a network (such as users, computers, and devices) into a hierarchical containment structure. What is Active Directory and why is it used?Active Directory stores information about objects on the network and makes this information easy for administrators and users to find and use. Active Directory uses a structured data store as the basis for a logical, hierarchical organization of directory information. What is Active Directory and example?An example of an Active Directory domain name would be ad-internal.company.com, where ad-internal is the name you are using for your internal AD domain, and company.com is the name of your external resources. Where is Active Directory database is stored?The AD database is stored in the NTDS.DIT file located in the NTDS folder of the system root, usually C:Windows. AD uses a concept known as multimaster replication to ensure that the data store is consistent on all DCs. This process is known as replication. What is Active Directory database and list the Active Directory database files?The NTDS.dit is a active directory database that is used to store entire Active Directory specific information. The NTDS. dit file on a particular domain controller contains all naming contexts hosted by that domain controller, including configuration and schema naming contexts. Which Active Directory component is responsible for authenticating users when they log on to a workstation?The Windows Domain Controller (DC), which is the server running the AD DS role, is the software/hardware that provides the AD set of services. The primary function of a domain controller is to authenticate and authorize all users and their resources into a Windows domain network. Which Usmt file is generated by running ScanState EXE with the Genconfig option?All applications should be installed on the destination computer before LoadState is used. The Config.xml file is generated by running ScanState.exe with the /genconfig option. What is the name of the domain controller database that Windows Server 2016 uses to store data about user access and resources on the network?Active Directory (AD) Which type of server is responsible for signing in clients that are joined to an Active Directory domain?The domain controller is the Microsoft Active Directory server responsible for responding to requests for authentication from users and computer accounts (for example, logging in and checking permissions) within the Windows Server domain. The Active Directory server contains the domain controller.
