Spank Protection | To guard against remote host attacks responding to TCP packets that have come from a multicast IP addresses. Attackers exploit this vulnerability by conducting a spank denial of service attack. This results in the host being shut down or the network traffic reaching saturation. Also, this vulnerability can be used by an attacker to conduct stealth port scans against the host. |
Smurf Protection | To guard against attacks where LAN Clients are being used as part of an Amplifier network. |
Land Attack Protection | To protect against a Layer 4 Denial of Service (DoS) attack where the attacker resets the source and destination information of a TCP segment to be the same. A vulnerable machine crashes or freezes because the packet is being repeatedly processed by the TCP stack. |
