Behavioral Analytics in Cybersecurity
SIEM
Behavioral analytics in cybersecurity is a data-driven technique that leverages machine learning (ML) and artificial intelligence (AI) to analyze patterns in user and entity behavior within networks, applications, and other digital environments. By identifying trends and anomalies, behavioral analytics helps detect potential security threats that might otherwise go unnoticed.
Behavioral analytics works by collecting vast amounts of data on how users and entities—such as employees, customers, or IoT devices—interact with a business’s systems. This data is then analyzed to identify normal patterns of behavior and to flag any deviations that may signal suspicious or malicious activities.
How Behavioral Analytics Works
Behavioral analytics compares current user activity to established behavioral baselines. By detecting anomalies—such as a user accessing unusual files, logging in at odd hours, or using a different device—behavioral analytics can alert security teams to possible threats before they escalate.
For example, if a typically office-bound employee logs in from an unfamiliar location late at night, this deviation from their normal pattern could be flagged as a potential breach. Behavioral analytics uses AI-driven algorithms to analyze data in real time, offering an additional layer of protection beyond traditional rule-based systems.
Key Benefits of Behavioral Analytics
Behavioral analytics can help your organization achieve several important cybersecurity outcomes:
- Real-time threat detection: Automatically alerts IT administrators to suspicious activities as they happen.
- Automated incident response: Automatically disconnects users or entities from the network if a threat is detected.
- Enhanced access security: Strengthens access control by identifying abnormal login attempts and activity patterns.
- Risk reduction: Proactively identifies and mitigates potential insider threats and data breaches.
- Improved user experience: Optimizes the user experience by flagging and resolving security issues without disrupting normal workflows.
Types of Behavioral Analytics
Behavioral analytics can be divided into two primary categories:
- User Behavior Analytics (UBA): Focuses on individual user activity and analyzes patterns to detect anomalies.
- User and Entity Behavior Analytics (UEBA): Extends UBA by monitoring not only users but also entities such as network devices, servers, and IoT devices. UEBA is more comprehensive and capable of identifying complex, multi-layered security threats.
The Difference Between UEBA and UBA
Before the development of UEBA, User Behavior Analytics (UBA) was the go-to cybersecurity tool for monitoring and analyzing user behavior within networks and systems. UBA uses advanced analytics to identify patterns of normal user activity and to detect deviations that could indicate potential security risks.
However, with the rise of Internet of Things (IoT) devices and the growing complexity of modern IT environments, the need for more expansive monitoring capabilities became evident. Gartner introduced User and Entity Behavior Analytics (UEBA) to fill this gap. Unlike UBA, UEBA tracks and analyzes the behavior of a wide range of entities beyond users, such as routers, endpoints, and servers. UEBA’s ability to monitor IoT devices individually or in peer groups makes it more effective at detecting threats in multi-device ecosystems.
UEBA also enhances security monitoring for cloud environments, where traditional tools struggle to keep up. By analyzing behavior across cloud-based assets, UEBA helps organizations detect suspicious activity that might indicate a breach or a misconfiguration in remote environments.
What to Look for in Behavioral Analytics Tools
When evaluating behavioral analytics tools, it’s essential to ensure they provide the following features:
- User behavior tracking: Capture and analyze what users click, where they encounter friction, and how they respond to changes in their environment.
- Funnel analysis: Understand how users move through steps to complete actions, such as making a purchase or signing into a secure system.
- Heatmaps: Visualize user interaction with your website or application to identify pain points, bugs, and areas of high activity.
- Customer behavior insights: Leverage data to personalize customer service and improve satisfaction by addressing users’ specific needs.
Behavioral Analytics vs. SIEM
Although both behavioral analytics and Security Information and Event Management (SIEM) solutions are essential to cybersecurity, they focus on different aspects of data:
- Behavioral Analytics: Uses machine learning to analyze user interactions, detecting deviations from normal behavior to provide proactive alerts. It’s most effective for detecting insider threats and compromised accounts.
- SIEM: Primarily collects and correlates security event data, providing a broader view of system logs and events. SIEM uses rule-based correlation and pattern recognition to identify potential threats.
However, the two technologies can complement each other. Many SIEM solutions now include UEBA modules, allowing organizations to enhance their security posture by integrating behavioral analytics within the SIEM framework.
Best Practices for Implementing Behavioral Analytics Solutions
To ensure the successful implementation of a behavioral analytics solution in your organization:
- Train your staff: Ensure that IT and security personnel are well-versed in how behavioral analytics works and how to act on its insights.
- Consider insider threats: Use behavioral analytics to detect insider threats that traditional security tools might miss.
- Use complementary tools: Behavioral analytics works best when integrated with other security tools like SIEM, endpoint detection and response (EDR), and network detection and response (NDR).
The Future of Behavioral Analytics
The future of behavioral analytics will be closely tied to advancements in AI and ML technologies. As these technologies continue to evolve, behavioral analytics will become even more powerful, allowing organizations to make data-driven decisions and detect increasingly sophisticated threats. Predictive analytics could enable companies to anticipate user needs and security risks before they arise, further personalizing customer experiences and strengthening cybersecurity measures.
In addition, behavioral analytics will play a critical role in the growth of zero trust security models, where continuous verification is essential for maintaining network security. By monitoring user behavior and detecting anomalies in real time, behavioral analytics can provide the insights needed to uphold the zero trust philosophy.
