Trellix Network Security and Forensics - Short Review

Overview of Trellix Network Forensics

Trellix Network Forensics is a comprehensive cybersecurity solution designed to enhance the detection, investigation, and response to security incidents within an organization’s network. Here’s a detailed look at what the product does and its key features:

Purpose and Functionality

Trellix Network Forensics is tailored to provide early incident detection and swift investigation capabilities, enabling organizations to determine the scope and impact of threats, contain them effectively, and resecure their networks. The solution captures and indexes full network packets at high speeds, allowing security teams to identify and resolve security incidents more rapidly.

Key Features

1. High-Performance Packet Capture

• The solution offers continuous lossless packet capture with time-stamping at speeds up to 20 Gbps. This ensures that all network traffic is recorded without data loss, even at high network speeds.

2. Centralized Analysis and Visualization

• Trellix Network Forensics includes a centralized workbench with an easy-to-use analytical interface. This allows analysts to review specific network packets and sessions before, during, and after an attack, providing deep insights into attacker activities.

3. Real-Time Indexing and Search

• The solution features real-time indexing of all captured packets, enabling ultrafast search and retrieval using a patented indexing architecture. This facilitates quick querying and retrieval of target connections and packets across all alerts, captured flow, and metadata.

4. Threat Hunting and Anomaly Detection

• The platform allows for effective threat hunting by identifying anomalies and suspicious activities that may have evaded detection by existing security tools. It helps in decoding protocols used by attackers to laterally spread attacks within the network.

5. Custom Dashboards and Visibility

• Users can create custom dashboards to view and share specific network metadata and activity. This centralizes the visibility of threat data, making it easier to monitor and analyze network traffic.

6. IOC Aggregation

• The solution consolidates alerts from other Trellix and third-party products, along with all network metadata, into a single workbench. This allows for immediate pivoting to session data with a single click, enhancing incident response efficiency.

7. Selective Filtering and Intelligent Capture

• Trellix Network Forensics includes intelligent capture with selective filtering, which helps in focusing on critical network traffic and reducing noise. This ensures that only relevant data is captured and analyzed, optimizing the investigation process.

Benefits

• Improved Response Quality: By providing detailed insights into network activities, the solution enhances the quality of incident response, allowing security teams to react swiftly and effectively.
• Quantification of Impact: It enables precise quantification of the impact of each security incident, helping organizations to better understand and mitigate threats.
• Reduced Risk: The centralized workbench and advanced analytics simplify investigations, reducing the risk associated with delayed or incomplete incident responses.

In summary, Trellix Network Forensics is a powerful tool for organizations seeking to enhance their network security posture through advanced packet capture, centralized analysis, and effective threat hunting capabilities.
