Create Normal Background Traffic
Generate background packets with varied addresses, ports, sizes and rates, or replay normal application PCAPs. Use real clients and servers when connections or full application interactions are required.

Why
Requirements
Single attack packets do not represent real security environments, which include normal traffic, scans, lateral movement, DNS/HTTP/TLS sessions, bursts, jitter and policy changes. Background traffic and replayable evidence are needed to assess detection accuracy and performance.
Traffic Generation provides background generation and attack PCAP replay; simultaneous modes require separate devices. ChaosBridge adds link degradation, while Flow Hunter observes sessions and captures before/after the security appliance, connecting input traffic to response.

Implementation
2
Replay Attack and Anomalous Samples
Replay attack PCAPs, malicious sessions, exploit samples, scans and historical incidents with configurable rates, loops, IPv4/port rewriting and mixing ratios.
3
Add Link Degradation and Load
Add ChaosBridge around the security path to emulate loss, delay, reordering and congestion. Check missed detections, incorrect blocking and performance drops.
4
Collect Evidence and Review Results
Flow Hunter observes session changes, alerts, blocking, retransmissions and PCAPs before/after the appliance, producing a detection-path review.

NetAccura Traffic Generation
NetAccura Traffic Generation
Generate L2-L3 test streams. Software models also replay Ethernet PCAPs, rewrite IPv4 addresses and TCP/UDP ports, and multiply traffic for performance, security detection and issue reproduction. Stop all transmit tasks before switching modes. Simultaneous generation and replay require separate devices.
Network Traffic Analyzer
Flow Hunter
Capture passively through mirrored ports or TAPs for L2-L7 analysis, session investigation, protocol-stage diagnosis and PCAP export.
Result
Expected Outcomes
Make Security Testing More Realistic
Combine normal traffic, attack samples, load and link anomalies to expose false positives, missed detections and performance issues.
Retain Evidence from Exercises
Provide attack traffic, before/after sessions and PCAPs rather than relying solely on alert screenshots.
Produce Reviewable Reports and Evidence
Deliver more than throughput or delay figures: include topology, parameters, timelines, quality curves, key sessions, anomalies, PCAP extracts and retest results. Development, testing, operations, vendors and customers can discuss the same evidence rather than relying on screenshots, verbal descriptions and repeated debate.
