This guide tells you how to configure Netflow collection protocol which accepts events from Netflow v5 and Netflow v9. You use this protocol to accept events for security purposes, not for network performance purposes. This means that you should choose to accept events from select key strategic points in your network only (not everywhere).

How Netflow Collection Works

The Log Collector service collects events from Netflow v5 and Netflow v9.

Deployment Scenario

The following figure illustrates how you deploy the Netflow Collection Protocol in Security Analytics.
