Ultimate Guide to Identity Threat Detection and Response (ITDR)

ITDR is a cybersecurity approach focused on protecting user identities and systems from cyber threats. It combines tools, processes, and best practices to detect and address  identity-based threats, such as compromised accounts and password leaks, focusing on prevention, identification, and response to attacks on identity infrastructure.

What is Identity Threat Detection and Response?

A thief wanting to gain entry to a house to steal something can try to pry open a locked back door or window, or he can simply walk in through the front door with a key as if he were a resident. This metaphor describes the scenario where an attacker abuses legitimate credentials to gain access to a network or system. The 2023 Verizon Data Breach Investigations Report declared the abuse of credentials to be the leading cause of breaches. According to the report, “74% of all breaches include the human element, with people being involved either via error, privilege misuse, use of stolen credentials, or social engineering.”

Organizations are adopting advanced security technologies encompassed within the framework of identity threat detection and response that unifies data to understand identity profiles and policies holistically. Gaining clear visibility of your identity attack surface can be enhanced with behavioral analytics to identify deviations from peer group baselines and derive context about the anomalous behavior from adjacent identity, access and security data.

Why ITDR Security Is Necessary

Organizations are increasingly adopting cloud-based systems, complicating access validation for a distributed workforce that includes third parties like vendors and contractors, adding complexity to the management of identity access to resources. Using the principles of zero trust, ITDR can limit access to those that need it. 

The vulnerabilities associated with user identities have become a prime target for malicious actors. Identity threat detection and response is necessary to reveal threats aimed at compromising credentials, accessing sensitive information, and/or exploiting weaknesses in identity management.

The Significance of ITDR in Cybersecurity

ITDR security continuously monitors and analyzes identity-related activities and contextualizes it with adjacent telemetry, enabling the timely and accurate detection of potential threats. This allows organizations to respond swiftly, mitigating the impact of identity-based attacks and preventing unauthorized access or data breaches.

Types of Identity Threats Addressed

Identity-based threats are especially difficult to detect, because they leverage legitimate credentials and appear to be permitted actions—to a point. Eventually there is some anomalous behavior that makes the activity stand out as suspicious. It’s important to note that an attack, or even an accidental action by an employee, can come from “inside the house” as easily as it can come from an outsider.

Some common types of identity threats include:

Account Takeover Attacks

A malicious actor gains unauthorized access to a user’s legitimate credentials and uses them to steal information, plant malware, commit fraud, etc. ITDR tools can detect and respond to these attacks by monitoring for unusual behavior and account activity, validating a true threat and automating response to force MFA, reduce access privileges or quarantine users or assets until remediated.

Insider Threats

Workers with legitimate credentials can intentionally or accidentally cause havoc by performing actions they shouldn’t be doing, such as uploading data to personal file shares, emailing proprietary data off the network or deleting data. If these actions are unusual for the worker, they can be flagged for investigation. The role of predictive security analytics for detecting insider threats is critical.

Misuse of Privileged Access

This is an insider threat whereby a person with privileged access rights attempts to do something they are not legitimately permitted to do, such as access sensitive data or systems, or create new accounts that can be used for further abuse. An identity threat detection and response solution would catch the behavior of this user and elevate the risk to the SOC based on the user’s privileges.

Phishing and Social Engineering

These types of threats misuse the trust and confidence of workers with access rights by tricking them to take harmful actions, such as typing their account information and passwords into a malicious website or surreptitiously downloading malware. ITDR systems can alert on an employee whose actions are anomalous or pose a risk to the business.

Key Components of ITDR Security

A complete ITDR system offers a comprehensive set of threat detection and response capabilities specifically designed to prevent breaches based on identity-based attacks. This includes identity and access analytics for visibility and identity governance, risk scoring, real-time monitoring, predictive analytics, and automated remediation and incident response.

Real-time Monitoring and Alerts

Continuous real-time monitoring of user identities and activities is crucial to detect potential cyber threats, like failed logins, unauthorized data access, or malware connections. ITDR tools help by immediately identifying risks and initiating swift actions, such as alerting or disabling suspicious accounts.

User and Entity Behavior Analytics (UEBA)

UEBA capabilities establish dynamic behavior baselines for every user and entity in the environment. This helps to identify anomalies in real-time that may indicate risk. Machine learning-based analytics can incorporate context around the suspicious activity by cross-validating anomalies with security alerts, privileges and other indicators of compromise in-order to determine whether a risk is actually a threat.

Risk Scoring and Prioritization

Not every anomaly is a threat, but all threats start with anomalies. By cross-validating behavioral, identity and security analytics you’re able to establish logical risk scoring to aid in prioritizing true threats and not endlessly chasing false positives. Risk scores need to be normalized on a fixed scale to be understandable and that they can’t be a static calculation, adjusting dynamically across the environment based on what is changing in real-time as other risks and threats present themselves. At the end of the day, context reigns supreme and false positives can deluge cand debilitate SOC teams.

Automated Incident Investigation and Response

With so many alerts and an overworked security team, it’s critical for an ITDR system to expedite the investigation process by collecting relevant contextual information and bringing it back to the security analyst from a single UI. In addition, response playbooks can be automatically triggered when true threats are identified.

The Benefits of Identity Threat Detection and Response

With identity being the new perimeter, the focus on identity-centric security is a powerful guardian, offering a multitude of benefits across various crucial aspects of an organization’s security posture. Among them are:

Enhanced Security Posture

Identity threat detection and response proactively hunts for identity system anomalies, reducing attack surfaces by managing vulnerable accounts and enhancing visibility into user activities, thus identifying and rectifying weak or misconfigured identity policies before exploitation.

Rapid Threat Mitigation

Real-time threat detection capabilities enable swifter responses to security incidents. This type of system can trigger automated countermeasures upon detecting suspicious activity, such as prompting for MFA, limiting access to sensitive data or completely  locking down compromised accounts. By minimizing the time attackers have unauthorized access to systems, itI significantly reduces the potential damage they can inflict.

Compliance and Reporting

Many regulations, like GDPR and HIPAA, mandate robust identity security measures. Identity detection and response helps an organization achieve and maintain compliance with  a proactive approach to identity threat detection. In addition, it provides comprehensive reports on user activity, access patterns, and threats. This data empowers the organization to identify trends, understand user behavior, and make informed security decisions. By analyzing the data, it’s possible to gain valuable insights into the organization’s security posture.

Fixing SOC Blindspots

By incorporating identity and access data into an enterprise data lake and deploying the advanced analytics capabilities of identity detection solutions the SOC is able to gain greater visibility and reduce false-positives.
