It is also an invaluable asset for organizations aiming to simplify their IT operations and strengthen their security. In turn, AD offers several key benefits.</p> <h4>Streamlined User Management</h4> <p>AD simplifies user account management by providing a centralized platform to create, modify or delete users across the entire network. This means that manual administration of users on individual machines within your network is a thing of the past.</p> <h4>Enhanced Network Security</h4> <p>AD’s robust security features safeguard sensitive data against cyber threats. Group policies and access controls enforce strict password requirements and limit users’ access to specific files or applications based on their specific roles within the company.</p> <h4>Simplified Resource Sharing</h4> <p>Sharing resources like printers or files across a network is much simpler with AD. Administrators can manage these resources centrally, making them available to all users without additional software installation.</p> <h4>Better Group Policy Implementation</h4> <p>The Group Policy feature in AD enables admins to control how systems operate and what users can do on those systems. From setting up <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="e3d8ca76-e45f-4756-962b-337673275a42" href="/us/threat-reference/firewall" title="Firewall">firewall</a> rules to disabling USB ports on endpoints for enhanced security--everything becomes easier with group policies in place.</p> <h4>Faster Troubleshooting</h4> <p>When issues arise, having a centralized system like AD helps diagnose problems faster by providing detailed logs about user activities and system events.</p> </div> </div> </div> </div> <div class="paragraph paragraph--type--space paragraph--view-mode--full space"> <div class="space__wrapper"> <div class="space__item space__md"> </div> </div> </div> <span data-smooth-scroll="true" class="anchor_link" id="toc-5"></span> <div class="paragraph paragraph--type--text-columns paragraph--view-mode--full text-cols"> <div class="block-text-cols__cols block-text-cols__cols-1"> <div class="paragraph paragraph--type--text-column paragraph--view-mode--default block-text-cols__cols__item"> <h3 class="block-text-cols__title">Active Directory Security</h3> <div class="block-text-cols__body"> <p>Active Directory offers security features like access control lists (ACLs), encryption and auditing capabilities to protect sensitive data and resources. These are all important features to employ. But comprehensive and ongoing Active Directory security involves many other steps and strategies.</p> <p>The following are some best practices for Active Directory security:</p> <h4>Strongly Secure Domain Administrator Accounts</h4> <p>Attackers are eager to compromise domain administrator accounts associated with your AD. That’s because these Active Directory users have high privileges with administrative control and authority over an entire domain within an AD “forest.” (A forest is a collection of one or more domain trees in the service directory.)</p> <p>One tip to secure domain admin accounts is to rename them from the default “administrator” to something more creative (and harder to guess). Implementing <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="0f4e4fcd-627a-406a-b38d-a613878b7b89" href="/us/blog/security-awareness-training/how-strong-my-password-guide-enable-your-employees-set-strong" title="How Strong Is My Password? A Guide to Enable Your Employees to Set Strong Passwords&nbsp;">strong password policies</a> and using passphrases can help here. Another good practice is to require <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="b8d75393-714c-4d80-9662-80f4c02efedc" href="/us/threat-reference/multifactor-authentication" title="Multifactor Authentication">MFA</a> for authentication for domain administrators.</p> <h4>Limit the Use of Highly Privileged Access to AD</h4> <p>Authorized personnel are the only users who should have administrative access in your AD. And those who have domain administrator privileges should not use those accounts for everyday tasks. For those they should use more typical user level accounts. Related measures for limiting Active Directory access—which can also help to reduce the risk of <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="dc00abb4-0611-4d1e-9b06-66929590f24f" href="/us/threat-reference/insider-threat" title="Insider Threat">insider threats</a>—include:</p> <ul> <li>Implementing the principle of least privilege (PoLP) to grant users only the permissions they need to perform their work—and no more.</li> <li>Using role-based access control (RBAC) to limit user access to specific tasks or systems.</li> <li>Auditing administrative accounts regularly.</li> </ul> <h4>Use a Locked-Down Secure Admin Workstation (SAW)</h4> <p>A SAW is a highly secure and isolated environment for performing administrative tasks in critical systems and services like Active Directory. The admin must originate from the SAW before they can perform any administrative task or connect to any other administered server or network. Some of the ways to “lock down” a SAW include:</p> <ul> <li>Using dedicated hardware or a virtual machine (VM) for administrative tasks.</li> <li>Hardening the SAW’s operating systems—for example, by disabling unnecessary services and features.</li> <li>Implementing strict access controls and user privilege management.</li> <li>Placing the SAW in a separate network segment.</li> <li>Reducing or eliminating direct internet connectivity to the SAW.</li> </ul> <h4>Disable Local Administrator Accounts</h4> <p>Local admins also have high privileges. But unlike domain admins, they are restricted to one, local machine. Local administrators have complete access to resources on the local server or client, though. And they can use their account to create local users, to assign user rights and access control permissions and to install software.</p> <p>Local admin accounts are often configured with the same password on every computer in a domain. So, an attacker only needs to compromise the credentials for one account to sign into others. Not surprisingly, <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="bbc64481-40a5-4e6d-8db9-f727f356b3a4" href="/us/threat-reference/threat-actor" title="Threat Actor">bad actors</a> often use unmanaged local administrator credentials in <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="4f5f680d-55f7-4589-b8c5-8db870462bb1" href="/us/threat-reference/ransomware" title="Ransomware">ransomware</a> attacks.</p> <p>You may want to consider disabling local admin accounts completely. You can instead set up individual accounts with the necessary rights to complete key tasks. To disable a local admin account, you will need to modify Group Policy settings in the Active Directory. Then, you can enforce security policies on Windows computers that are joined to the domain.</p> <h4>Use Managed Service Accounts (MSA)</h4> <p>MSA accounts have complex passwords that AD manages automatically. The AD domain controller rotates the passwords regularly, so the risk of passwords for service accounts being weak, stale or exposed is reduced. By eliminating manual password changes the likelihood of human error is minimized. So, too, is the risk of service disruptions due to password changes.</p> <p>(Note: MSAs are available in Windows Server 2008 R2 and later, including Windows Server 2012, 2012 R2, 2016, 2019 and 2022. The specific features and capabilities of MSAs may vary depending on the version of Windows Server in use.)</p> <h4>Find and Remove Unused Accounts</h4> <p>Creating a formal process to identify inactive users and unused or orphaned accounts in your AD can help ensure you stay on top of this risk. As part of that process, you will need to determine the criteria for identifying inactive accounts, such as a specific period of inactivity (like 90 days). You should also notify relevant stakeholders to make sure that the identified accounts can be deleted safely.</p> <p>Taking the time to back up your AD environment before you start to remove accounts is also a wise practice. You may want to document the accounts you plan to remove and cite the reasons for deleting them, just so you have a record.</p> <h4>Be Vigilant About Patch Management and Vulnerability Scanning</h4> <p>This tip may seem mundane or obvious. However, you need to move fast to <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="f7d3ef6a-7c69-45a6-bd6b-4659dabcfb1b" href="/us/threat-reference/patch-management" title="Patch Management">patch</a> Active Directory vulnerabilities, just as you should do to protect any other critical system. Be sure to scan for and remediate AD vulnerabilities often—once a month or on a more frequent basis, if possible. Prioritize fixes that pose the most serious risk to your business and users. And identify and address any outdated or unsupported software as well.</p> <p>By implementing these <a data-entity-substitution="canonical" data-entity-type="node" data-entity-uuid="1d0563b3-eb95-4e77-a62b-dd8fb65360de" href="/us/blog/insider-threat-management/10-essential-cybersecurity-best-practices-proofpoint" title="10 Essential Cybersecurity Best Practices | Proofpoint">security best practices</a>, organizations can strengthen their AD security posture and minimize the risks to their IT infrastructure.</p> </div> </div> </div> </div> <div class="paragraph paragraph--type--space paragraph--view-mode--full space"> <div class="space__wrapper"> <div class="space__item space__md"> </div> </div> </div> <span data-smooth-scroll="true" class="anchor_link" id="toc-6"></span> <div class="paragraph paragraph--type--text-columns paragraph--view-mode--full text-cols"> <div class="block-text-cols__cols block-text-cols__cols-1"> <div class="paragraph paragraph--type--text-column paragraph--view-mode--default block-text-cols__cols__item"> <h3 class="block-text-cols__title">Active Directory: The Authority in Enterprise Resource Management</h3> <div class="block-text-cols__body"> <p>Active Directory is the ultimate directory service that keeps stored data organized, optimized and secure.
