What is UEBA: The Complete Guide to User and Entity Behavior Analytics

17.04.2024 Read

As the world becomes increasingly digital, cyber-attacks are becoming more sophisticated, and traditional security measures, like firewalls and passwords, are no longer sufficient in protecting sensitive data.

This raises a critical question: how can organizations identify hidden threats lurking within their networks? While traditional security analytics solutions can miss these hidden threats, UEBA emerges as a promising tool that uses AI to monitor user behavior anomalies and flag the ones that might indicate a cyberattack.

In this comprehensive guide, we'll break down UEBA, how it works, and why it's crucial for an organization's cybersecurity.

Understanding User and Entity Behavior Analytics

UEBA, or User and Entity Behavior Analytics, is a powerful cybersecurity behavior analysis tool that uses ML and statistical analysis to create a comprehensive understanding of activity within your network.

UEBA tools can flag anything from unauthorized access attempts by compromised accounts to unusual data transfers that could signal exfiltration attempts or malware infections.

Here are the key benefits of UEBA:

  • Automated threat detection: Optimizes resources and detects threats such as compromised accounts, brute force attacks, and data breaches.
  • Risk reduction: Detects breached user accounts early to prevent potential loss or damage.
  • Faster response time: Uses precise risk scoring to minimize reaction time to breaches.
  • Less noise: Reduces false positives and helps prioritize significant risks, enhancing security team effectiveness.

In essence, UEBA technology acts as a proactive guardian and provides constant cybersecurity monitoring for anomaly detection for entities that traditional security measures might miss. UEBA solutions not only provide user activity analysis but can analyze the behavior of devices, applications, and even data itself.

Difference between UEBA and Traditional Security Tools

While traditional security tools remain fundamental to cybersecurity, they often treat authorized user actions as routine. The technology of user behavior analytics brings a new level of insight by focusing on behavior patterns.

This comparative table illustrates the importance of User and Entity Behavior Analytics:

UEBA is capable of identifying unauthorized attempts, an excessive number of failed logins, or an authorized user login from an unfamiliar device or location as suspicious behavior. It prevents attackers from gaining system access via phishing or stolen credentials and enhances the overall robustness of cybersecurity measures.

UEBA vs SIEM: A comparison

While they may seem to serve similar purposes, SIEM and UEBA are two critical tools in any security professional's arsenal. When used together, they excel in providing a comprehensive view of network activity.

SIEM provides raw data from various sources, which is enriched by UEBA with contextual information and behavioral insights. SIEM's rules and correlations help identify known threats, while UEBA's ML and statistical models detect unknown or emerging threats through entity behavior monitoring and entity risk management.

SIEM alerts cybersecurity teams about security issues and supports forensic analysis and compliance through log management. UEBA generates user risk profiling scores to prioritize investigations and aids in root cause analysis by providing user profiles.

Both systems monitor for suspicious user types, with SIEM focusing on excessive data access and unauthorized logins, and UEBA detecting abnormal behaviors and signs of manipulation through predictive analytics in security.

A Step-by-step Guide to Implementing UEBA

Implementing UEBA deployment strategies demands thorough planning and integration with existing security setups. Following best practices for UEBA implementation ensures an advanced threat detection and response to cybersecurity needs.

Here are tips for successful UEBA integration:

1. Define Your Security Objectives

The first step is to clearly define what you want to achieve with UEBA. You can start by identifying the specific areas you're most concerned about, such as insider threat detection, advanced malware infections, or unauthorized access attempts. Identify key data sources for analysis, such as user activity logs, network traffic, file access logs, and email communications.

2. Select a UEBA Solution

When choosing a UEBA vendor, consider the following:

  • Machine Learning Capabilities: Opt for a solution that uses advanced machine learning to analyze behavior patterns, improving detection accuracy over time.
  • Data Source Integration: The UEBA should integrate with security infrastructure and ingest data from identified sources for anomaly detection in cybersecurity.
  • SIEM Integration: A UEBA that integrates with SIEM can provide a comprehensive view of security events, simplifying threat detection and response.

3. Data Setup and Quality Management

The next critical step is establishing data collection processes. Configure data pipelines to gather information from your identified sources and ensure its quality before feeding it into the UEBA system. Data inconsistencies or errors can significantly hinder the effectiveness of anomaly detection. Data normalization and cleansing techniques might be necessary to prepare your data for analysis.

4. Baseline Creation and Fine-Tuning

Allow the UEBA system sufficient time to analyze historical data and establish baseline behavior patterns for users and entities within your network. This process involves behavioral analytics for security, where the UEBA system analyzes user and entity actions to identify patterns and establish what constitutes normal behavior.

During this initial period, it's crucial to monitor the system's performance and fine-tune detection rules, including security event correlation, to minimize false positives. Expect this stage to be iterative, requiring adjustments as the system learns and refines its understanding of normal activity.

5. Continuous Monitoring and Improvement

UEBA is not a "set it and forget it" solution. Maintenance is essential in security monitoring solutions to ensure its effectiveness. Regularly review the system's performance metrics, such as the number of alerts generated and their accuracy.

As user behavior monitoring evolves, adjust baselines accordingly to maintain optimal detection capabilities. Refine detection rules based on real-world security incidents and threat intelligence feeds to ensure the system stays up-to-date with the latest attack methods.

6. Integration and Team Training

For a successful UEBA implementation, integrate the chosen solution with existing security tools to foster a unified security posture. This will streamline workflows and allow the security team to leverage the insights generated by UEBA alongside data from other security solutions. Train the security team on interpreting UEBA alerts and effectively responding to potential security incidents identified by the system.
