Definition: A Network Traffic Monitoring Dashboard consolidates flow data, packet captures, and IDS/IPS alerts into a single operational view of what is moving across the network and whether any of it deviates from baseline.
Features:
( Ownership ) Built and maintained by the network security engineering team and used day to day by the SOC and NOC for detection and troubleshooting.
( Data Sources ) Combines flow data, packet captures, and IDS/IPS alerts into one operational view.
( Anomaly Detection ) Surfaces subtle traffic anomalies such as reconnaissance scans, slow data exfiltration, and protocol-layer floods.
( Prevents Blind Spots ) Without centralized visibility, these anomalies go unnoticed until they escalate into an outage or breach.

| Field | Description |
|---|---|
| Data Source | Flow export, mirrored traffic, or IDS/IPS feed contributing to the view, e.g. NetFlow, sFlow, packet capture |
| Metric / Widget | Displayed measure, e.g. throughput by segment, top talkers, protocol distribution |
| Baseline Range | Expected normal value or pattern for the metric |
| Alert Threshold | Value that triggers an anomaly alert, e.g. sudden spike in outbound volume |
| Alert Severity | Priority assigned to threshold breaches, e.g. low / medium / critical |
| Escalation Path | Team or on-call rotation notified when a critical alert fires |
| Retention Window | How long historical traffic data is kept for investigation |
| Dashboard Owner | Team responsible for maintaining widgets and thresholds |
The dashboard ingests data continuously; the NOC watches it around the clock for operational anomalies and escalates suspected security events to the SOC, which periodically tunes alert thresholds based on investigation outcomes.
III. Best Practices & Comparison
| Document | Primary Purpose | Update Cadence | Owner |
|---|---|---|---|
| Network Traffic Monitoring Dashboard | Continuous visibility into traffic volume, mix, and anomalies | Continuous (real-time) | Network Security Engineering / NOC / SOC |
| Network Access Control Log | Records discrete access decisions rather than ongoing traffic patterns | Continuous (event-driven) | NOC / SOC |
| SASE (Secure Access Service Edge) | Cloud-delivered architecture combining network and security monitoring at the edge | As-needed on strategy revision | Network Security Engineering |
- Establish traffic baselines per segment before setting alert thresholds, to reduce false positives.
- Correlate flow anomalies with IDS/IPS and access logs rather than treating any single feed as sufficient.
- Retain historical traffic data long enough to support post-incident forensic review.
- Review and tune alert thresholds regularly as network usage patterns evolve.
- Assign clear on-call ownership so critical alerts are never left unacknowledged.
