Description: SYN attack - Number of un-Acked Syns
What is asmSynatkNumberofunAckedSyns?
This is the current count of TCP handshakes the gateway is tracking that have sent a SYN but not yet completed with a final ACK. This is effectively a live gauge of half-open connection pressure on the gateway, and a number that keeps climbing rather than draining is the direct signal of an in-progress SYN flood consuming connection-table resources. For example, this value holding steady around 5,000 unacknowledged SYNs would indicate a sustained low-grade SYN flood rather than a single passing burst.
