What Is ITDR

Gartner listed identity threat detection and response (ITDR) among its top security and risk management trends for 2022 and beyond - and study after study keeps verifying the importance of an effective ITDR strategy. For example, the Identity Defined Security Alliance (IDSA) revealed that more than 90% of the organizations it surveyed suffered an identity-related attack in 2023, and a 2024 IBM report found that attacks using stolen credentials increased by 71% year over year.

To help your organization defend against identity threats, this article provides an in-depth guide to ITDR, including the key capabilities to look for when evaluating candidate tools.

Understanding ITDR

ITDR is not a single process or piece of software. Rather, it is a framework focused on detecting and responding to suspicious activity related to identities, such as privilege escalation attempts and repeated failed logons. Accordingly, an effective ITDR strategy involves using a combination of processes, tools and policies to protect identities and the systems that house them.

ITDR doesn't replace other core security disciplines like privileged access management (PAM), vulnerability scanning and data loss prevention (DLP). Rather, it is a another layer of security that complements your existing tools and processes.

Key Components of ITDR

A comprehensive ITDR security system includes three core functions: identity monitoring, threat detection and incident response.

Identity Monitoring

Continuous monitoring of identities and their activity is essential to spotting and thwarting threats. A solid ITDR system will establish baseline of the normal behavior of each identity, typically using technologies like machine learning (ML) and artificial intelligence (AI) to analyze past activity and uncover patterns. It will then watch user activity, looking for any aberrant actions that could indicate that the account is being misused by its owner or has been taken over by an adversary.

In addition to monitoring the activity of users, an ITDR system needs to carefully track all activity around the identities themselves, such as any expected creation of accounts or granting of new privileges to existing accounts.

All this monitoring needs to happen in real time so that the organization can be alerted to threats in time to respond effectively and prevent serious damage.

Threat Detection

A modern IT ecosystem is bursting with activity, and not every anomalous event is a threat. For example, multiple unsuccessful login attempts could be an adversary trying to breach the network - or simply the legitimate account owner struggling to remember or correctly type their password.

To avoid overloading security teams with alerts, ITDR solutions need to accurately identify true threats and weed out false alarms. To do this, they normally rely on user behavior analytics (UBA) to compare current activity to the established baseline of normal behaviors for the identity. For example, UBA can determine that a user is not only accessing sensitive data but doing so at an unusual time or from an unexpected location, which means the activity is more likely to be a true threat. This analysis feeds risk scoring, where the tool assigns each anomaly a number that represents its potential of becoming a security threat.

Incident Response

ITDR solutions facilitate response to threats in multiple ways. They often provide dashboards and reports that display potential threats and their rankings, and offer real-time alerts that notify security teams about high-risk activity by email, text or other channels.

In addition, most advanced ITDR systems can respond to some threats automatically: Security teams build response playbooks that define threat indicators and the actions to be triggered in response. Examples of these actions include:

• Disconnecting compromised systems and applications from the network
• Disabling the offending user account and resetting its password
• Executing a specified PowerShell script
• Reverting an unwanted change, such as a modification to folder permissions

Why ITDR Is Essential Today

While ITDR has always been important, several modern realities make it absolutely essential today. They include the explosion in remote work, increasingly strict compliance mandates and the rapidly evolving threat landscape.

Modern Work Environments

Remote and hybrid work has become common in recent years. While this shift offers a wealth of benefits like increased productivity and cost savings, it has also introduced a new cybersecurity risk: Traditional access management and security controls like network firewalls are simply no longer sufficient for a strong cybersecurity posture. Instead, organizations need to layer on robust identity threat detection and response strategies to prevent, detect and respond to identity-based threats.

Stringent Compliance Requirements

Many organizations today must comply with strict regulations for controlling access to sensitive data. While mandates like the Payment Card Industry Data Security Standard (PCI DSS) and the Health Insurance Portability and Accountability Act (HIPAA) have been around for years, new laws are constantly being added. For example, the General Data Protection Regulation (GDPR) has broad reach and violations can result in extremely hefty fines, and similar data privacy laws are being introduced by other national and state governments.

An effective ITDR strategy is essential for achieving, maintaining and proving compliance with many regulations because ITDR helps organizations effectively manage access to regulated data, including financial transactions, medical records and customer information.

Sophisticated and Relentless Cyberattacks

Identity-related cyberattacks have increased in recent years, and adversaries are using more sophisticated tactics and techniques. Moreover, there are now open-source tools and even services available that enable less technical threat actors to discover weak points in an organization's defenses and launch targeted attacks.

ITDR can help organizations mitigate their risk from these rapidly evolving threats. For example, it can help them block, detect and respond to social engineering attacks like phishing scams, in which hackers manipulate or trick users into giving them confidential information such as their credentials. ITDR can also help organizations spot and shut down credential stuffingattacks, which use automated tools to try to log on using stolen credentials.

What to Look for in an ITDR Solution

When assessing identity threat detection and response tools, be sure to check for the following features:

• Comprehensive preventive controls - To prevent identity threat actors from compromising your systems, an ITDR solution should provide or integrate smoothly with identity and access management (IAM) features like multifactor authentication (MFA), role-based access control (RBAC) and stringent access policies.
• Continuous identity discovery - In any modern IT environment, identities are frequently being created, deleted and modified. Look for an ITDR solution that will keep up by maintaining an up-to-date inventory of all identities and their access privileges and alerting you to any suspicious changes.
• Real-time threat detection - To detect identity threats in time to prevent significant damage, you need an ITDR solution that delivers real-time threat detection. To enable your security teams to focus on true threats, look for advanced analytics and UBA powered by technologies like ML and AI.
• Automated remediation - Automation is essential for neutralizing identity threats as quickly as possible. Check candidate solution for a robust set of automated response actions and an easy-to-use interface for defining the criteria that will trigger them.
• Deception-based detection of privilege escalation - While threat actors often gain a foothold in the network by compromising the credentials of regular users, they usually need elevated privileges to access sensitive systems and data. Therefore, make sure the ITDR solution you choose can spot common privilege escalation tactics. For even more effective protection, look for a tool that offers deception-based features like honeypots and decoy accounts to lure in malicious actors and proactively thwart their activity.

ITDR Challenges and Trends

Organizations worldwide are recognizing the importance of ITDR. In fact, 75% of security personnel now leverage ITDR-based security tools, according to a 2024 report from Anomali. However, integrating ITDR with other security systems remains a challenge. Gaps often stem from disparate data sources, inconsistencies across security layers and varying levels of identity management maturity. Malicious actors can exploit these gaps to gain unauthorized access, evade detection and compromise critical systems.

The market is responding. Emerging trends that can enhance ITDR effectiveness include the following:

• Advancements in ML and AI - We've barely scratched the surface of the capabilities of AI and ML for strengthening security. As these technologies get better and better, we can expect identity threat detection response solutions to become more accurate and efficient.
• Better integration - Vendors are working to enable ITDR solutions to integrate seamlessly with both existing security tools and emerging technologies.
• Evolving regulatory landscape - Government bodies at all levels are increasingly passing laws to protect the privacy of residents and consumers. Accordingly, ITDR solution providers will need to continue working to balance security with privacy concerns, for example, by ensuring that identity monitoring practices are transparent and respect user consent.
