IBM's QFlow and VFlow offer deep application visibility through layer 7 traffic capture and analysis, facilitating enhanced network, application, and user monitoring. These tools integrate with QRadar SIEM for improved security intelligence and can detect threats such as zero-day attacks while ensuring compliance and thorough forensic investigations. Key features include deep packet inspection, stateful application classification, and passive monitoring for asset profiling.

2. 2 IBM Security
 Layer 7 traffic capture and analysis
for deep application insight
 Network, application and user
activity monitoring
 Full integration with QRadar SIEM
and QRadar Risk Manager
QRadar QFlow and QRadar VFlow Overview
QRadar QFlow monitors traffic in physical
environments and QRadar VFlow in virtual / cloud
environments to provide advanced flow collection and
analysis for Layer 7 visibility, via deep packet
inspection and stateful application classification
Key Capabilities Benefits
 Reduce the risk and severity of
security breaches
 Ensure regulatory and internal
policy compliance
 Perform more complete and
accurate forensic investigations
Network and Application Visibility
 Layer 7 application monitoring
 Content capture

QRadar QFlow & VFlow: Application Layer visibility and content awareness
• Provides Layer 7 visibility and stateful
classification of applications and protocols
• Uses Deep Packet Inspection (DPI)
technology to sample payload content and
identify malicious transfers
• Passive activity monitoring helps identify
and automatically configure new hosts,
assets and services within QRadar SIEM
Core Features
 VFlow delivers application layer visibility
of all virtual network traffic
 Runs as virtual host software on the
virtual server, not requiring additional
hardware
 Analyzes port mirrored traffic for a
physical network switch bridging gap
between physical and virtual realm

4. 4 IBM Security
 Network traffic doesn’t lie. Attackers can stop logging and
erase their tracks, but can’t cut off the network (flow data)
• Deep packet inspection for Layer 7 flow data
• Pivoting, drill-down and data mining on flow sources for advanced
detection and forensics
 Helps detect anomalies that might otherwise get missed
 Enables visibility into attacker communications
Differentiated by network flow analytics

5. 5 IBM Security
 Helps detect zero-day attacks that have no signature
 Enables policy monitoring and rogue server identification
 Provides visibility into all attacker communications
 Uses passive monitoring to build asset profiles and classify hosts
 Improves network visibility and helps resolve traffic problems
Flows provide context for true network intelligence
