Enhancing Your Organization’s Security with Microsoft Sentinel’s User Entity Behavior Analytics (UEBA)

Microsoft Sentinel is a cloud-native security information event management (SIEM) system that utilizes User Entity Behavior Analytics (UEBA) to enhance an organization’s security. UEBA technology provides a more accurate baseline for modeling user behavior, which in turn enables the detection of anomalous behavior.

In this blog post, I will share insights from the User Entity Behavior Analytics | Microsoft Sentinel in the Field #14 Youtube video on how Microsoft Sentinel’s User Entity Behavior Analytics (UEBA) can enhance your organization’s security

More Accurate Baseline for User Behavior

UEBA technology allows Microsoft Sentinel to create a more accurate baseline for user behavior by analyzing various data sources, including user activity, network traffic, and endpoint data. By creating a baseline of normal user behavior, Microsoft Sentinel can identify deviations from that baseline and alert security teams to potential security threats.

Detailed Information about IPs and Geolocation

Microsoft Sentinel is implementing a new layer of data to identify potential security threats by analyzing user activity and providing detailed information about IPs and geolocation. This information helps security teams quickly identify potential threats and take action to mitigate them.

Easy Integration with Data Sources

Customer data is transformed and stored in Sentinel’s UEBA engine, which can be enabled through settings and data source integration for behavior analytics and identity info. This easy integration allows organizations to quickly start utilizing UEBA technology without the need for additional infrastructure or setup.

AAD IP in Azure Identity Protection

Azure Active Directory (AAD) IP in Azure Identity Protection provides risk level, watchlist tags, VIP user status, blast radius, and user origin in hybrid environments, with user attribute changes logged in the identity info table for easy tracking and correlation. This information allows security teams to quickly identify and investigate potential security threats.

Rich Event Information for Investigation

Sentinel’s behavioral analytics table provides enriched information on events, including anomalies, for deep dive investigations or hunting rules. This information allows security teams to quickly investigate potential security threats and take action to mitigate them.

Utilizing MITRE ATT&CK

When anomalous activity is detected in PowerShell account creation, use UEBA outputs and MITRE ATT&CK for investigation and adjust the anomaly score in Sentinel. This integration with MITRE ATT&CK provides security teams with a framework for investigating and responding to security threats.

Content Hub Solution

Use UEBA’s Content Hub solution and its 23 hunting queries to investigate anomalies and enhance the value of your organization’s security. This feature provides security teams with a library of hunting queries that can be used to quickly investigate potential security threats.

A Must-Have Tool for SOCs

UEBA is a must-have tool for Security Operations Centers (SOCs). Its ability to identify anomalous behavior, provide detailed information about potential security threats, and integrate with other security technologies makes it an essential tool for enhancing an organization’s security posture.

Conclusion

Microsoft Sentinel’s UEBA technology provides a powerful tool for enhancing an organization’s security posture. Its ability to identify anomalous behavior, provide detailed information about potential security threats, and integrate with other security technologies makes it a must-have tool for Security Operations Centers.
