Examples of Flow Alerts
Use Case #1 - Possible Port Scanning
The user computers are generating too many SYN connections per minutes and this may be sign of a port scanning in progress.
Use Case #2 - Possible Cluster Node Failure
When the active nodes in a cluster attempt to connect to an unresponsive node, UNUM Insight Analytics Flow records an excessive number of connections in SYN state for the cluster housekeeping protocol.
