Ultimate Guide to Identity Threat Detection and Response (ITDR)
ITDR, standing for Identity Threat Detection and Response, represents an innovative category of cybersecurity solutions dedicated to safeguarding user identities and identity-based systems from cyber threats. Organizations need to adopt an approach that integrates a blend of security tools, processes, and best practices aimed at anticipating, identifying, and addressing threats associated with identity. These threats encompass both credential compromise or misuse as well as the management of credentials, access, and entitlements. The primary focus of ITDR solutions is on identifying, mitigating, and responding to potential identity-based threats, including attacks on identity infrastructure, compromised user accounts, and leaked passwords.
What is Identity Threat Detection and Response?
A thief wanting to gain entry to a house to steal something can try mightily 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 of the home. This metaphor describes the scenario where an attacker abuses legitimate credentials to gain access to a network or system. It has become such a commonplace scenario that 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.”
Amid the heightened threat posed by identity-based attacks, organizations are adopting advanced security technologies encompassed within the framework of ITDR. At the heart of any ITDR solution is the unification of identity data to understand the identity profiles and policies holistically. Having this visibility and understanding of your identity attack surface is then further complemented with behavioral based security analytics. Combined, you’re able to identify deviations from peer group baselines and derive context about the anomalous behavior from adjacent identity, access and security data.
Why ITDR Is Necessary
ITDR security is critical in today’s landscape due to the escalating frequency and sophistication of identity-based attacks. Organizations increasingly rely on cloud-based and interconnected systems, each with their own method for validating access for a distributed workforce that often includes third parties like vendors and contractors. What’s more, the number of device, application, and service entities on networks is growing exponentially, contributing to the complexity of understanding who or what is accessing enterprise resources, and for what purpose.
The vulnerabilities associated with user identities have become a prime target for malicious actors. ITDR is necessary to preemptively identify, investigate, and respond to 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 proactive stance allows organizations to respond swiftly, mitigating the impact of identity-based attacks and preventing unauthorized access or data breaches. Additionally, ITDR contributes to enhanced visibility into the attack surface of identities, facilitating better governance, risk assessment, and strategic decision-making. In essence, ITDR serves as a fundamental component in the toolbox of cybersecurity measures, fortifying defenses against evolving threats in the digital landscape.
Types of Identity Threats Addressed by ITDR
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. What’s more, 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 ITDR solution would catch the behavior of this user and elevate the risk to the SOC based on an understanding of the user’s sensitive 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
A critical first step is the continuous and real-time monitoring of identities and their actions for suspicious activity, for example, failed login attempts, unauthorized access to critical data or connections to a known malware site may signal a potential cyberattack. Through real-time scrutiny of user accounts and activity logs, ITDR tools can promptly detect potential threats and trigger immediate alerts or automated responses, such as disconnecting a misbehaving account.
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 ITDR won’t be deemed successful if it adds to the false positive deluge currently debilitating 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, ITDR’s 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
Using proactive threat detection techniques, ITDR goes beyond static defenses, actively seeking out suspicious activity within an organization’s identity systems. By identifying and addressing vulnerabilities in the identity infrastructure, such as abandoned, orphaned or over-privileged accounts, ITDR shrinks the attack surface available to malicious actors. Moreover, ITDR provides improved visibility and context with a holistic view of user activity and access across systems, shedding light on previously hidden connections and anomalies. This in particular helps with finding misconfigured or weak identity policies that need to be addressed prior to being exploited.
Rapid Threat Mitigation
ITDR’s 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, ITDR significantly reduces the potential damage they can inflict.
Compliance and Reporting
Many regulations, like GDPR and HIPAA, mandate robust identity security measures. ITDR helps an organization achieve and maintain compliance by demonstrating a proactive approach to identity threat detection and response. In addition, ITDR provides comprehensive reports on user activity, access patterns, and detected threats. This data empowers the organization to identify trends, understand user behavior, and make informed security decisions. By analyzing ITDR data, it’s possible to gain valuable insights into the organization’s security posture and identify areas for improvement.
Fixing SOC Blindspots
By incorporating identity and access data into an enterprise data lake and deploying the advanced analytics capabilities of ITDR solutions the SOC is able to gain greater visibility and reduce false-positives.
