Network Security
Flow Collector Sensor
A network device or software agent that passively gathers, aggregates, and forwards network flow records (such as NetFlow, IPFIX, or sFlow) for traffic analysis, anomaly detection, or forensic investigation. See NIST SP 800-137 and IETF RFC 3954.
Quick answer: A network device or software agent that passively gathers, aggregates, and forwards network flow records (such as NetFlow, IPFIX, or sFlow) for traffic analysis, anomaly detection, or forensic investigation. See NIST SP 800-137 and IETF RFC 3954.

Why it matters
Flow Collector Sensor matters because it supports clear communication in Network Security contexts for SOC Analysts, Security Engineers, and Incident Responders. It also connects to aviation training and exam language such as CISSP, CompTIA Security+, and CEH.

Operational example
Deploy a flow collector sensor on the core switch to aggregate NetFlow records from all VLANs for monitoring east-west and north-south traffic.
