One of the major tasks of IT administrators is to manage their assets across enterprise networks efficiently. They need to keep a close check on user authorizations across the network and manage permissions. As organizations grow, however, they expand their network, which also increases their threat surface. Misconfigurations or failures in implementing authentication, authorization, and accounting (AAA) policies often lead to data breaches and compliance lapses. Keeping track of orphaned accounts and countering privilege escalation attacks also becomes challenging. In this complex and ever-evolving threat landscape, efficient management of Active Directory (AD) is of primary importance.
What Is Active Directory?
Active Directory helps IT teams monitor various network objects, grant and revoke different user permissions, and implement policies for smooth operations within a network. For example, an admin can create a group of users and allocate them specific access permissions to directories on the server. As the network grows, however, it can become difficult for admins to track users, login details, resource allocation details, and permissions. Active Directory is one of the most important IT infrastructure tools, and it helps admins manage user provisioning processes, security, and audits and provides access to each user’s account from a single location. With the help of Active Directory, users can be organized logically into groups and subgroups to provide access control.
Active Directory is a Microsoft product and runs on Windows Server operating systems. It includes several services to manage permissions and provides access to resources in a network.
In Active Directory, data is stored as objects. An object can be understood as a single element, such as a user, group, application, or device. Objects can either be resources or security principals like users or groups. Every object has a name and attributes. For example, a user’s name might be a combination of a name string and information associated with the user.
The Active Directory structure is comprised of three main components: domains, trees, and forests. Several objects, like users or devices that use the same AD database, can be grouped into a single domain. Domains have a domain name system (DNS) structure. Multiple domains can be combined to form a group known as a tree. The tree structure uses a contiguous namespace to arrange domains in a logical hierarchy. Different domains in a tree share a secure connection and trust each other in a hierarchy. This means the first domain can implicitly trust the third domain in a hierarchy. A collection of multiple trees is called a forest. Admins can allocate specific access rights and communication privileges at all levels. Moreover, a forest also includes directory schemas, shared catalogs, domain configurations, and application information. The global catalog servers provide a list of all the objects in a forest, and the schema defines the class and attributes of an object in a forest. Organizational units (OUs) organize groups, users, and devices. Every domain can contain its own OU.
Active Directory provides several services like Domain Services, Lightweight Directory Services, Certificate Services, Federation Services, and Rights Management Services. These services fall under Active Directory Domain Services (AD DS). AD DS comes with Windows Server and is designed to manage client systems. AD DS can be considered the main service of Active Directory; it stores directory information and takes care of the interaction between the user and the domain. When a user tries to connect to a device, server, or resource over a network, AD DS checks the login credentials and access permissions given to the user. Other products like SharePoint Server and Exchange Server also depend on AD DS for resource access.
Active Directory Certificate Services (AD CS) creates, shares, and manages certificates. These certificates enable users to exchange information over the internet securely.
Active Directory Lightweight Directory Services (AD LDS) has the same function as AD DS. AD LDS can store directory data using Lightweight Directory Access Protocol (LDAP) and run numerous instances on a single server. The LDAP application protocol stores data related to objects in directory services, like usernames and passwords, and shares them across the network.
Active Directory Federation Services (AD FS) uses the concept of single sign-on (SSO) to validate users, and it allows them to access multiple applications on different networks in a single session. With SSO, users need to sign in only once for each service.
Active Directory Rights Management Services (AD RMS) protects confidential and discrete information from unauthorized access by encrypting the content on a server.
Active Directory comes with Microsoft Server operating systems and offers a diverse set of features and services. Active Directory helps IT professionals allocate access rights to new hires (account provisioning) and revoke access rights for employees who are leaving the company (account de-provisioning). While Active Directory Domain Services plays a vital role in organizations, it doesn’t natively provide security against cybercrimes. If there’s suspicious activity, IT teams need to go through logs manually and spend time pinpointing areas in need of rectification. This is because the integrated tools that come with Active Directory may not be very effective or helpful at the enterprise level.
Active Directory management tools help overcome these issues. Fortunately, it’s easy to enhance the capabilities of the existing Active Directory suite with third-party software or tools. From automated alert systems to reporting capabilities, there are plenty of products available to fit your needs.
Companies need to understand their requirements and choose the best Active Directory management tools for their needs. Moreover, the third-party software they choose should work well with the existing digital environment and resolve issues related to cybersecurity and networking.
Active Directory management (AD management) ensures Active Directory is working as required. AD management is the process of managing and monitoring the operations of the Active Directory services found in Windows Server operating systems. AD management is also a part of the network or server monitoring and management processes.
Active Directory monitoring can help automate Active Directory user provisioning processes, comply with regulations and audits, provide security, and grant access to users’ accounts from a central location. Network administrators using AD and Windows Server’s native administration and management features can perform this service manually. This process can also be performed using customized software designed to automate Active Directory monitoring.
Benefits of Implementing an Active Directory Environment
A Better Representation of the Network
The Active Directory structure provides a clear picture of the network. Active Directory allows admins to centrally manage users and authorizations, regardless of the size of the network. A centralized approach to management is one of the most important reasons to implement Active Directory.
Single Sign-On Capability
Imagine a situation where a user has to memorize several passwords and usernames for various servers. This situation can become even more complicated, especially when the number of users increases. To simplify this, a domain controller can be added to the environment. The single sign-on (SSO) capability of the domain controller allows users to enter their usernames and passwords on one server and access other servers without having to enter these details again.
Efficient Management of Trust Relationships
Active Directory allows the use of trust relationships among various domains. This means that a two-way trust relationship can exist between two entities. For example, if there is a two-way trust relationship between two websites, the users can use the resources on both sites with a single password and username.
Centralized Policy-Based Management
Centralized policy-based management is another benefit of Active Directory. This feature helps manage and improve the security settings of workstations from a single point. This means admins can monitor, control, and manage the security settings of all the network resources from a single point.
Improved Scalability With Organizational Units
Active Directory uses the concept of organizational units (OUs) to improve scalability in large organizations. An OU can be defined as a collection of users and computers. When companies have large domains, they can be organized into OUs. For example, a company has a huge HR department and there is an admin managing the entire domain. The company can create an OU named HR, and all the user accounts and computers related to HR can be moved to it. The admin who is responsible for this OU can be given certain administrative rights limited to this OU.
Multi-Master Replication and Sites
The concept of multi-master replication and sites is another amazing benefit of an Active Directory environment. Every domain controller contains a copy of Active Directory in an Active Directory multi-master replication environment. Whenever a change is made to Active Directory, the closest domain controller will update accordingly. Other domain controllers in the environment will also update themselves. This concept also applies to sites. Each site has its own domain controller, so when a user within a site updates the Active Directory, the changes are reflected in the domain controller within the site. The domain controller on the other side of the site will also update the changes at regular intervals.
How Does Active Directory Work?
When you begin installing a Windows computer, all the systems are workgroups or standalone computers. There’s no domain present at this stage. Such an environment includes several systems, workstations, or servers with separate passwords and usernames.
With the help of Active Directory, you can organize all the information related to users, systems, and devices in a single place. The information related to the Active Directory, users, groups, and passwords is stored in an AD database known as the NTDS.DIT file (NT Directory Services).
Initially, all the systems are separate devices. To reap the benefits of Active Directory, the Active Directory Domain Services must be installed on a server. This server contains the NTDS.DIT database file. Information about users, computer accounts, user groups, and passwords will be stored in this database file. After the creation of the file, admins can create a domain controller. A domain can have multiple domain controllers.
Active Directory uses a security mechanism known as Kerberos. Once the user enters his or her login details, Kerberos grants a Ticket Granting Ticket (TGT) to the user through a ticket-granting system. The user then presents this ticket to other workstations and servers throughout the same domain (or even on other domains where a trust relationship exists). The servers identify the ticket and understand it’s been issued by a trusted domain controller. After authorization, the users get the permissions necessary to complete their intended tasks.
Active Directory maintains consistency among several domain controllers. It’s possible to have multiple domain controllers in an environment. Large organizations normally have multiple domain controllers, so admins must ensure all the domain controllers contain the same information. To maintain consistency, Active Directory implements synchronization mechanisms to ensure all domain controllers have consistent data.
