Exabeam Overview
Exabeam is a comprehensive security intelligence platform designed to help organizations detect, investigate, and respond to security threats across their entire IT infrastructure. Here’s a detailed look at what Exabeam does and its key features.
Core Functionality
Exabeam is built to overcome the limitations of traditional security products that often operate in silos, failing to share critical data effectively. It integrates advanced security analytics with automated threat detection, investigation, and response (TDIR) capabilities, making it easier for security teams to outsmart attackers.
Key Features and Functionality
Security Data Collection and Management
Exabeam collects logs, events, and data from diverse sources, including security tools, endpoints, cloud platforms, and more. It efficiently parses and stores this data in various formats, minimizing storage footprint and providing fast search and analysis across hot, warm, and cold data archives.
User and Entity Behavior Analytics (UEBA)
Exabeam uses UEBA to identify anomalous activities by establishing user and device baselines to understand normal behavior. This helps in detecting insider threats, lateral movement, and credential changes, among other anomalies.
Threat Detection and Investigation
The platform employs advanced algorithms and machine learning to analyze enriched data, identifying suspicious activities and potential threats. It triggers alerts for suspicious events and provides investigators with contextual information and automated timelines, streamlining the investigation process.
Incident Response and Automation
Exabeam automates routine tasks such as containment and remediation through automated response scripts and security orchestration, automation, and response (SOAR) integrations. This enables quick and effective responses to security incidents.
Security Compliance
Exabeam helps organizations comply with various security regulations, such as HIPAA and PCI DSS, by providing audit trails and reports that demonstrate a proactive security posture.
Additional Capabilities
- Insider Threat Detection: Detects suspicious behavior by internal users, indicating potential malicious intent or compromised accounts.
- Fraud Prevention: Identifies suspicious financial transactions and user activities related to known fraud patterns.
- IoT Security: Monitors and secures Internet of Things (IoT) devices, detecting vulnerabilities and suspicious communication patterns.
- Cloud Security: Extends security intelligence to cloud environments, providing visibility and threat detection across cloud infrastructure.
- Endpoint Security: Integrates with endpoint security solutions to gain deeper insights into endpoint activity and identify potential malware or unauthorized access attempts.
- Security Operations Center (SOC) Optimization: Centralizes and streamlines SOC operations, enhancing team efficiency and threat response times.
Exabeam Security Operations Platform
Exabeam’s platform includes several key components:
Exabeam Security Analytics
This component provides automated threat detection powered by UEBA, correlation, and threat intelligence. It is designed to operate on and enhance existing SIEM or data lake solutions, offering deeper detection and improved triage capabilities.
Exabeam Security Investigation
This feature builds on the UEBA capabilities with content, workflows, and automation to provide intelligent triage for the TDIR workflow. It includes dynamic alert prioritization and turnkey playbooks for automating repeated workflows.
Exabeam Fusion
Exabeam Fusion combines cloud-scale security log management, SIEM, security analytics, and security investigation capabilities. It offers rapid data ingestion, simplified search experiences, and powerful behavioral analytics to uncover weak signals that other tools might miss. Fusion accelerates investigations, reduces response times, and ensures consistent, repeatable results.
Architecture and Workflow
Exabeam’s architecture includes several layers:
- Data Collection Layer: Gathers data from various sources.
- Normalization and Enrichment Layer: Cleanses, normalizes, and enriches data with contextual information.
- Analytics and Detection Layer: Uses advanced analytics engines and machine learning to identify suspicious activities.
- Investigation and Response Layer: Provides tools for investigating alerts and orchestrating response actions.
- Reporting and Compliance Layer: Generates reports on security posture and compliance requirements.
- Threat Intelligence Layer: Integrates with threat intelligence feeds to update detection rules and enhance threat awareness.
Automation and AI
Exabeam leverages automation and AI to enhance the security workflow. It automates evidence collection with timelines, visualizes the investigation scope, and uses context-aware risk scoring to prioritize alerts. The platform also integrates generative AI to provide event context and accelerate investigations.
In summary, Exabeam is a robust security intelligence platform that automates and streamlines the entire TDIR workflow, providing advanced analytics, automation, and compliance features to help organizations effectively protect their systems and data from evolving cyber threats.
