Overview
Why NDR is so important
Networks are the foundation of today’s connected world, making them a prime target of cyber attackers looking to cause disruption and a key source of data for threat detection and analysis. IBM Security® QRadar® Network Detection and Response (NDR) helps your security teams by analyzing network activity in real time. It combines depth and breadth of visibility with high-quality data and analytics to fuel actionable insights and response.
How it’s used
Stop data exfiltration

Reduce dwell time with quick detection
Attackers are patient, often exfiltrating data in small, infrequent batches. Uncover sensitive data moving across your network in real time by way of emails, chat messages, file uploads and downloads or social media.
Discover compromised devices

Automatically update assets to stay ahead of attackers
See new devices as they connect to your network. Continuously profile assets based on attributes and behavior to uncover threats, compromised devices and shadow IT.
Perform threat hunting

Shift from reactive to proactive
Query historical network activity to search for past activity, discover unusual behavior, and identify the assets involved to help prevent similar attacks in the future.
Benefits
Eliminate blind spots
Detect threats faster
Use existing investments
Features
QRadar Flows
Threats hide within the volume of normal traffic on your network. Get a broad network view across a wide range of network devices.
QRadar Network Insights
Analyze and correlate network data in real time. Network insights provides for session reconstruction, full packet capture, extraction of key metadata, and application analysis.
QRadar Network Threat Analytics
Detect slight changes in user or system behavior that might have gone unnoticed by baselining for normal network activity, scouting for anomalies, and identifying suspicious behavior.
DNS Analyzer Application
Get insights into your local DNS traffic by identifying malicious activity and enabling your security team to detect Domain Generated Algorithm (DGA), Tunneling, or Squatting domains that are being accessed from within your network.
QRadar Incident Forensics
Retrace the step-by-step actions of cyber criminals by rebuilding data and retracing actions. Captures, reconstructs, and replays the entire event chain.
QRadar Network Packet Capture
Delivers an optional appliance to store and manage data used by QRadar Incident Forensics when no other network packet capture (Network PCAP) device is deployed.
Mohawk College improves visibility and detection
Visibility is critical to improving network detection and response. The college chose IBM Security® QRadar® SIEM to help it gain visibility into its environment to detect, investigate and respond to cybersecurity breaches.
