ITDR Combines and Refines Familiar Cybersecurity Approaches

The advantages of using proactive approaches to identify threats before the attackers can cause too much damage are clear to enterprise security teams. One such approach, identity threat detection and response (ITDR), focuses on finding and mitigating threats by monitoring user behavior and detecting anomalies.

ITDR involves continuous monitoring of user identities, activities, and access patterns within an organization’s network. Security teams use ITDR tools to detect and respond to potential threats and unauthorized access attempts in real time.

ITDR typically involves the following key components:

• Data collection: Gathering user activity data from various sources, such as log files, network traffic, and application usage.
• User profiling: Creating a baseline of normal user behavior patterns, including access habits, data usage, and time spent on specific tasks.
• Anomaly detection: Comparing current user activities with the established baseline to identify deviations that may indicate potential threats or unauthorized access attempts.
• Alerting and response: Notifying IT security teams of suspicious activities and providing them with the necessary information to investigate and remediate threats.
• Continuous improvement: Updating user behavior baselines and refining detection algorithms as users and threats evolve.

ITDR is not an entirely new concept, as it builds upon established methodologies such as fraud detection and user entity behavioral analysis (UEBA).

Fraud detection refers to the process of identifying and preventing fraudulent activities, such as unauthorized transactions or account takeovers, in industries like banking and finance. Fraud detection systems analyze vast amounts of data, including user behavior, transaction patterns, and historical trends, to identify anomalies that may signal fraud. By detecting potential fraud early, organizations can mitigate financial losses and protect their customers’ trust.

Similarly, UEBA is a security approach that focuses on detecting and preventing insider threats by monitoring user activities within an organization’s network. UEBA solutions analyze user behavior patterns — such as login times, data access, and system usage — to identify deviations that may indicate malicious intent or compromised accounts. By detecting potential insider threats early, organizations can prevent data breaches and minimize damage to their reputation.

How ITDR, Fraud Detection, and UEBA Are Similar

At their core, ITDR, fraud detection, and UEBA share the common goal of identifying and mitigating potential threats by monitoring user behavior and detecting anomalies. While their specific applications may differ, they all leverage advanced analytics, machine learning algorithms, and continuous monitoring to achieve this goal. Here are some key similarities between these approaches:

• Centered on data: All three methodologies rely on the collection and analysis of large volumes of data to detect potential threats. This includes user activities, access patterns, and historical trends, which are used to create a baseline of normal behavior and identify deviations.
• Real-time monitoring and detection: ITDR, fraud detection, and UEBA solutions continuously monitor user activities and analyze data in real time to detect potential threats as they occur. This enables organizations to respond quickly to incidents and minimize damage.
• Anomaly detection and alerting: These methodologies employ advanced analytics and machine learning algorithms to identify anomalies that may signal potential threats. Upon detection, IT security teams are alerted, enabling them to investigate and remediate incidents.
• Emphasis on adapting and evolving: ITDR, fraud detection, and UEBA solutions are designed to adapt and evolve as user behavior and threat landscapes change. By continuously updating behavior baselines and refining detection algorithms, these systems remain effective in detecting new and emerging threats.
• Focus on prevention: These approaches emphasize proactive threat detection and response, aiming to identify potential incidents before they can cause significant harm. By focusing on prevention, organizations can reduce the impact of security breaches and protect their valuable assets.

Risks and Rewards of Moving to ITDR

As the cybersecurity landscape continues to evolve, the need for innovative and proactive security solutions becomes increasingly apparent. Heidi Shey, principal analyst at Forrester Research, predicted two serious risks CISOs will encounter in implementing ITDR. First, a C-level executive to be fired for their firm’s use of employee monitoring, which can violate data protection laws like GDPR. Second, a Global 500 firm will be exposed for burning out its cybersecurity employees, who are expected to be available 24/7 through major incidents, stay on top of every risk, and deliver results in limited timeframes.

Finally, Shey also predicted that at least three cyber insurance providers will acquire a managed detection and response (MDR) provider in 2023, continuing the trend that Acrisure started in 2022. These MDR acquisitions will give insurers high-value data about attacker activity to refine underwriting guidelines, unparalleled visibility into policyholder environments, and the ability to verify attestations. Such moves will change cyber insurance market dynamics and the requirements for coverage and pricing, which should help push security measures like ITDR into common use.

ITDR is not a radical departure from established cybersecurity methodologies, but rather an extension and refinement of existing practices. By recognizing the common threads between ITDR, fraud detection, and UEBA, organizations can build on their existing security investments and expertise to create a more comprehensive and robust security posture.
