<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">With the growing prevalence of credential-based cyberattacks, protecting digital identities has become a critical priority for businesses. It’s far easier for attackers to exploit credentials, such as passwords, than to breach highly fortified systems. For organizations, safeguarding and monitoring access within their Identity and Access Management (IAM) frameworks has never been more essential. This article dives into the implementation of Identity Threat Detection and Response (ITDR) systems, offering a unified approach to prevention, detection, and response, and taking cybersecurity beyond just prevention methodologies.</p>

<h2 class="font-bold text-h3 leading-[40px] pt-[21px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">Why is Identity Threat Detection Crucial?</h2>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">User credentials, such as usernames and passwords, are among the most frequent targets for cyber attackers. They often provide direct access to critical systems and sensitive data, making them one of the biggest vulnerabilities in modern security landscapes. Reports show that many data breaches originate from stolen, compromised, or misused credentials, making credential security a pressing challenge.</p>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">IAM, or Identity and Access Management, is the framework businesses use to control and secure access to resources. Traditionally, IAM has focused on preventive measures like multi-factor authentication (MFA) and role-based access control (RBAC). While these methods are essential, they fail to address the gaps around detecting and responding to credential misuse. This is where ITDR systems step in to bridge the gap, combining IAM with Security Information and Event Management (SIEM) systems for a holistic security approach.</p>

<h2 class="font-bold text-h3 leading-[40px] pt-[21px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">What Are ITDR Systems?</h2>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Identity Threat Detection and Response (ITDR) systems are cybersecurity platforms that combine identity management and security monitoring to tackle credential-related risks. Unlike traditional preventive tools, ITDR delivers robust measures for threat detection and response. ITDR systems operate across three key phases:</p>

<h3 class="font-bold text-h4 leading-[30px] pt-[15px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">The Collection Phase</h3>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">The foundation of ITDR systems begins with precise data collection. These systems gather valuable insights from various sources, including:</p>

<ul class="pt-[9px] pb-[2px] pl-[24px] list-disc [&amp;_ul]:pt-[5px] pt-[5px]">
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="1"><b><strong class="font-bold">Identity Providers (IDPs):</strong></b> These platforms are responsible for user authentication processes and often enable Single Sign-On (SSO) capabilities. They provide key insights into user behavior, such as access patterns and failed authentication attempts.</li>
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="2"><b><strong class="font-bold">Directories:</strong></b> Directories store vital information, such as usernames, hashed passwords, and user roles. Common examples include systems utilizing Lightweight Directory Access Protocol (LDAP) or Microsoft Active Directory.</li>
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="3"><b><strong class="font-bold">Network Flow Data:</strong></b> Capturing network activity provides additional context to log files. Unlike logs that could be tempered with, network flow data ensures added visibility across organizational traffic.</li>
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="4"><b><strong class="font-bold">Firewall and Security Logs:</strong></b> These logs track access attempts to sensitive resources, helping identify possible intrusions or unauthorized access attempts.</li>

</ul>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">By consolidating data from these sources, ITDR systems offer a centralized and holistic view of identity activity across an enterprise, enabling organizations to monitor patterns and detect anomalies effectively. These insights are often presented through customizable dashboards, providing actionable intelligence about risky behaviors and suspicious accounts.</p>

<h3 class="font-bold text-h4 leading-[30px] pt-[15px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">The Detection Phase</h3>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">ITDR systems excel at detecting anomalies and identifying patterns that traditional tools might overlook. Unlike traditional SIEM tools that focus on events that <i><em class="italic">did happen</em></i> (e.g., a login attempt), ITDR systems can recognize activities that <i><em class="italic">should have happened</em></i> but didn’t. For example:</p>

<ul class="pt-[9px] pb-[2px] pl-[24px] list-disc [&amp;_ul]:pt-[5px] pt-[5px]">
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="1">A user logs in but skips the expected MFA step.</li>

</ul>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">ITDR systems employ advanced techniques, such as state diagrams, to map expected workflows and identify deviations. For instance:</p>

<ul class="pt-[9px] pb-[2px] pl-[24px] list-disc [&amp;_ul]:pt-[5px] pt-[5px]">
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="1">Internal users should access general applications after appropriate authentication.</li>
 	<li class="text-body font-regular leading-[24px] my-[5px] [&amp;&gt;ol]:!pt-0 [&amp;&gt;ol]:!pb-0 [&amp;&gt;ul]:!pt-0 [&amp;&gt;ul]:!pb-0" value="2">External users should log in via a VPN (Virtual Private Network), complete MFA, and then access sensitive applications.</li>
</ul>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">Deviations from these expected workflows raise red flags and trigger alerts for further investigation.</p>

<h3 class="font-bold text-h4 leading-[30px] pt-[15px] pb-[2px] [&amp;_a]:underline-offset-[6px] [&amp;_.underline]:underline-offset-[6px]" dir="ltr">The Response Phase</h3>
<p class="text-body font-regular leading-[24px] pt-[9px] pb-[2px]" dir="ltr">When ITDR systems detect a threat, they immediately initiate response actions to minimize damage and prevent escalation. Common response actions include:</p>

<ul class="pt-[9px] pb-[2px] pl-[24px] list-disc [&amp;_ul]:pt-[5px] pt-[5px]">
