This counter tracks the total number of SYN flood attacks the Topsec IDS has detected, a denial-of-service technique that overwhelms a target with half-open TCP connection attempts. An admin monitors this counter to catch attempts to exhaust a server's connection table and deny service to legitimate clients. For example, a sharp rise in idsSynflood detections aimed at a specific server would prompt the admin to check that server's SYN cookie or connection-limiting defenses.
