This counter tracks the total number of IP spoofing attacks the Topsec IDS has detected, where packets carry a forged source IP address to disguise the true origin or impersonate a trusted host. An admin monitors this counter to catch attempts to bypass IP-based access controls or launch reflection/amplification attacks. For example, a rising idsIpspoof count could indicate an attacker forging internal IP addresses to slip traffic past address-based firewall rules.
