Explanation
sFlow is a network monitoring protocol that samples packets and exports network-layer statistics (primarily Layers 2–4), providing visibility into traffic volumes, flows, and device-level data. For sFlow to be a useful addition to the SOC's monitoring capabilities, the engineering team must ensure that application layer visualizers are available. Without tools that can translate sFlow's network-level data into application-layer context-such as identifying which application generated a flow, correlating traffic to known threats, or visualizing behavior patterns-the raw sFlow data has limited actionable value for security analysts. Network taps (A) are not required since sFlow is agent-based on switches. Bandwidth (B) and log aggregator placement (C) are secondary concerns compared to the ability to interpret the data meaningfully.
