LogRhythm NetMon

Real-Time Visibility into What's Happening on Your Network

Network monitoring plays an essential role in helping detect, stop, and recover from attacks. As threats can bypass perimeter defenses or originate from within, having visibility into your network traffic allows you to immediately recognize suspicious issues.

LogRhythm NetMon provides the real-time visibility and security analytics you need to monitor your organization’s entire network.

Top Network Traffic Analysis Use Cases

Surface data exfiltration activities: 
Identify long-running sessions, “low and slow” sessions hidden in normal traffic, anomalous outbound network sessions, and other activities indicative of data exfiltration.

Discover operational anomalies:
Verify that you aren’t seeing protocols or traffic that you think you’ve blocked or traffic between systems that should be isolated from each other.

Find hidden security threats: 
Catch security threats hiding in low-level chatty protocols like DNS, SNMP, or Kerberos.

Expose nuisance apps and bandwidth hogs: 
Discover when apps that are against corporate policy are being used. Find out who or what is taking up the most bandwidth.

Detect botnets and beaconing: 
Identify traffic using anomalous ports. View malformed packet headers. Recognize command and control callbacks.

See where your network traffic is going: 
Identify outbound IP and URL destinations and classify traffic by ingress, egress, or lateral motion in your network.

See More Activity on Your Network with Deep Packet Analytics

NetMon’s Deep Packet Inspection (DPI) engine gives you a deep understanding of your network activity in an easy-to-access format. It identifies and categorizes thousands of applications at wire speed and populates thousands of metadata fields. NetMon also analyzes and extracts Layer 2–7 network data using a variety of methods, including pattern matching, heuristic modeling, and signatures for session identification.

Deep Packet Analytics (DPA) builds upon DPI to provide a richer source of visibility into network traffic, including immediate recognition of PII, credit card information, port and protocol mismatch, and other key data revealing inappropriate data movement. DPA allows for continuous correlation against full packet payloads and metadata using prebuilt and custom rule sets and provides unprecedented control over alarming and response at the flow and packet level.. Through DPA rules, you can automate threat detection that was previously only possible via manual packet analysis.

Go Further with Network Detection and Response

When a threat crosses your network, time is of the essence. While NetMon helps you detect threats, a solution with centralized analysis and full response capabilities means you can remediate them at lightning speed.

LogRhythm NetworkXDR goes beyond network traffic monitoring to provide complete visibility, machine-based analysis, threat corroboration, and prebuilt response capabilities for real-time network detection and response. With NetworkXDR, broad-spectrum network data flows from NetMon sensors to the LogRhythm NextGen SIEM Platform. The SIEM further enriches this data with environmental and threat context and applies dynamic machine analytics, including known indicators of compromise (IOC) signature-based inspection, tactics, techniques, and procedures (TTP) scenario-based modeling and behavioral analysis to expose evolving threats more effectively.

The result is full coverage against known and unknown network threats without the need for heavy tuning or lengthy machine learning training periods.
