What Is Active Directory Management?

Effective AD management streamlines user identity and lifecycle management while strengthening security and compliance.  

Overview

Discover the essentials of Active Directory management, backup, and recovery 

As the standard directory service for Windows domain networks, Active Directory (AD) is the foundation of user identity management for countless enterprises and organizations. This role makes AD a prime target for threat actors – and makes effective AD management a top priority not only from an IT standpoint, but for cybersecurity risk reduction as well.   
 
By following best practices for managing AD, complemented with comprehensive AD backup and recovery, you can: 

• Enhance security and compliance  
• Unify identities across hybrid environments  
• Streamline user lifecycle management
• Improve system performance 
 
Here’s what you need to know about AD and how best to manage it.

What Is AD, and What Does it Do? 

Provided by Microsoft for organizations using Windows Server, AD is the user identity database an overwhelming majority of enterprises rely on to manage access and permissions for network resources. Its policy management tools, automated identity workflows, authentication and authorization mechanisms, reporting tools, and other features help IT teams manage and govern identities and accounts across networks and systems.  
 
The role of AD in network infrastructure includes: 

Centralized authentication – When users log into a Windows domain network, AD verifies their credentials and determines their access rights for network resources.  

Resource access control – AD manages and enforces security policies across the network, controlling access to files, applications, and services based on user roles and permissions. 

Hierarchical structure – To allow efficient management of large-scale networks, AD organizes network elements into a structure of trees, forests, domains, and organizational units.  

Group policy management – Administrators can use AD to implement and manage group-specific policies for security settings and computer configurations across the network.  
 
These functions are enabled through a set of logical components, physical components, and services and protocols. Understanding these core components helps administrators manage and use AD effectively to organize network resources, control access, and maintain security in Windows-based environments. 
 
Ranked from smallest to largest, the logical components of AD include: 

• Objects – The smallest units in AD, objects represent entities like user accounts, computers, and groups.  

Organizational units – OUs are containers used to group related objects, such as employees within the same business unit, resources in a given location, users with similar access privileges, or similar types of devices. They help in assigning administrative duties and enforcing group policies. 

Domains – The primary organizational units in AD, domains define administrative boundaries within a network and contain users, computers, groups, and other objects. Each domain has its own security policies and user accounts. 

Trees – A  tree is a hierarchical structure of one or more domains that are connected through trust relationships or share a contiguous namespace. 

Forests – The highest level of AD structure, a forest is a collection of one or more domain trees that share a common schema, configuration, and global catalog. An organization’s AD forest serves as its main security boundary.  
 
Physical components of AD include: 

Domain Services – The core component of AD, Domain Services are responsible for managing authentication and authorization of users and computers in the network. 

Domain controllers – Domain controller servers host Domain Services and are used to store user account information, manage authentication and authorization requests, and replicate changes to other domain controllers in the domain. 

Global catalog servers – Global catalog servers enable searches for objects across domains by storing partial copies of all AD objects. They also play a key role in authentication by helping locate user accounts during login.  
 
Services and protocols of AD include: 

Lightweight Directory Access Protocol – LDAP, the protocol AD uses to access and manage directory information, provides a standardized way for other services to interact with its directory service. 

Group Policy – Administrators use Group Policy to define, manage, and enforce policies, security settings, and other configurations for users and computers within the AD forest. 

AD Management

Basic Tasks of AD Management 

AD management includes a variety of tasks, but the most important are: 

User and group management – A fundamental aspect of AD management, this includes creating and maintaining user accounts, organizing them into logical groups, assigning permissions and access rights, and managing user authentication and authorization.  

Group Policy management – Admins use Group Policy to create and configure Group Policy Objects to apply and enforce consistent security, user settings, and configurations for users, computers, and OUs across the network. 

Domain controller management – To maintain a secure, reliable, and efficient network infrastructure, admins can add or remove domain controllers; assign individual domain controllers to be in charge of specific operations; and monitor replication between domain controllers.  

Security and access control Maintaining security in AD includes implementing and managing authentication mechanisms, configuring and monitoring access controls, managing security certificates, implementing security best practices, and monitoring for potential threats.  

Benefits

Benefits of Effective AD Management 

By following best practices for the four key elements of AD management, you can help enable a secure, efficient, and well-organized network infrastructure. This enables benefits such as: 

Enhanced security and compliance – A well-organized network infrastructure makes it possible to implement strong authentication mechanisms, enforce access controls, and maintain appropriate and up-to-date security policies for users, groups, and devices across the network. Standardized, automated access approval processes and AD reporting capabilities aid compliance and facilitate audits.  

Unified identities across hybrid environments – AD lets you consolidate identity and permissions management across environments, including AD, Azure AD, UNIX/Linux and Mac OS environments, and cloud-based resources. This makes it simpler to maintain consistent centralized control of user access to applications, databases, and SaaS resources of all types. 

Streamlined user lifecycle management – Effective AD management enables automated user lifecycle processes, including provisioning, modifying, and deprovisioning user accounts. This improves operational efficiency while helping you maintain the principle of least privilege, a key element of modern security.   

Improved system performance – A clean and well-organized AD environment reduces the load on servers to improve response times for queries and overall system performance. This leads to a better user experience and more efficient network operations.

Backup and Recovery 

AD Backup and Recovery 

The central role of AD in both user identity management and security, as well as its desirability as a target for cyberattack, make AD backup and recovery absolutely critical. By following consistent practices to back up AD, including the user accounts, permissions, and network resource configurations stored in its database, you can help enable recovery of this vital data in case of corruption, accidental deletion, or system failure. 
 
The importance of AD backup can be seen in contexts including: 

Disaster recovery – If AD is unavailable, related users can’t log in and systems cannot function properly. A full AD backup helps you restore operations more quickly following a catastrophic failure like a hardware malfunction, cyberattack, or natural disaster.  

Cyber threat mitigation – As ransomware and other cyberattacks targeting AD increase, having backups can help you avoid the security vulnerabilities introduced by a compromised AD database and the need to pay ransom to recover its data.  

Regulatory compliance – Regulations requiring data protection and retention often include a requirement to back up AD. 

Best practices for AD Backup and Recovery:

Many of the best practices for AD backup are similar to those for other forms of enterprise data – and their implementation is just as essential.

• Perform regular, full AD backups – Most organizations back up AD fully every 24 hours. Avoid relying solely on incremental backups, as they can complicate the recovery process. For larger systems with frequent changes, consider backing up twice a day. 

Backup multiple domain controllers – Back up at least two domain controllers per domain in your AD forest. This provides redundancy and increases the chances of successful recovery in case of failure. 

Use consistent AD backup methods – Back up AD using software that provides data consistency, such as those compatible with Microsoft Volume Shadow Copy Service. This preserves the integrity of the AD database during the backup process. 

Secure AD backup storage – Store AD backups securely, ideally following the 3-2-1 backup rule, with multiple copies stored on different media in different locations. This protects backups from unauthorized access and potential data breaches. 

Decouple AD backups from OS and data backups – Separating AD backups from OS and data backups helps prevent potential malware infections and helps enable a clean recovery of AD. 

Regularly test AD backup and recovery processes – Include AD backup and recovery testing in your disaster recovery plan. Regularly verify that your backups are functional and that you successfully can restore AD when needed. 
 
As with backup and recovery in general, the key to an effective AD backup practice is consistency. By adhering to best practices, you can keep your enterprise directory available to support continuous business operations.
