Active Directory (AD), a vital component of IT infrastructure, often becomes a primary target for threat actors seeking unauthorized access. It\u2019s also an easy target most of the time, because in a lot of companies the AD has been installed with Windows Server NT4.0 somewhere in the late 1990\u2019s and migrated to newer Windows Server versions ever since, but never properly reinstalled or reconfigured. Basically most AD\u2019s are roughly 25 years old, thus date from another era in IT, one during which cyber security wasn\u2019t a big concern yet.<br \/>\nIn this blog post, we will explore some proactive measures to fortify Active Directory security.<\/p>\n<p><span data-contrast=\"auto\">T<\/span><span data-contrast=\"auto\">hreat actors frequently compromise AD Domain Administrator accounts, enabling them to swiftly gain control over an organization&#8217;s network. Common entry points for threat actors include exploiting vulnerabilities in internet-facing devices, compromised credentials through theft or guessing, and malware delivered via phishing emails or drive-by downloads.<\/span> <span data-contrast=\"auto\">This highlights the importance of implementing least privilege access and reinforcing AD security controls to counter potential attacks.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">To defend against attacks and enhance AD security, organizations should adopt proactive measures that create obstacles for threat actors. <\/span><span data-contrast=\"auto\">Following actions are considered best practices:<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<ol>\n<li><span data-contrast=\"auto\"><strong>Conduct an AD Security Assessment:<\/strong> An AD Security Assessment evaluates an organization&#8217;s AD implementation, identifying configuration weaknesses and potential attack vectors. By leveraging configuration review tool sets and interviews with internal personnel, organizations gain valuable insights into their AD environment, enabling them to address vulnerabilities and enhance their security posture.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"auto\"><strong>Reduce Privileged Accounts:<\/strong> Organizations often overlook the presence of numerous privileged accounts within their network, creating an exploitable attack surface. Reviewing and reducing the number of privileged accounts minimizes the risk of unauthorized access and helps manage privileges more effectively.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"auto\"><strong>Review Service Principal Names (SPNs):<\/strong> Service principal names (SPNs) play a critical role in AD authentication. Securing SPNs involves identifying accounts with attached SPNs, reviewing their password status, and ensuring they are not members of privileged groups. By minimizing the number of accounts with SPNs, organizations reduce the potential attack surface and mitigate the risk of impersonation attacks.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"auto\"><strong>Utilize Group-Managed Service Accounts:<\/strong> Group-managed service accounts offer efficient management of service account passwords, including Kerberos, administrator, service, and user accounts. Resetting passwords on all accounts, including service accounts, after evicting threat actors from a compromised environment enhances security without risking application functionality.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<\/ol>\n<p><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559685&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">By investing time and resources in securing Active Directory, organizations can significantly enhance their resilience against cyber intrusions. <\/span><span data-contrast=\"auto\">At Dilaco we partner with <\/span><span data-contrast=\"auto\">Secureworks<sup>\u00ae<\/sup> <\/span><span data-contrast=\"auto\">to help our customers fortify their AD by i<\/span><span data-contrast=\"auto\">mplementing the recommended measures<\/span><span data-contrast=\"auto\">.
