Understanding Attack Defense

Because enabling all attack defense functions places a heavy burden over the FW system and may affect service availability, you are advised to learn the basics of attack defense before enabling attack defense functions.

Anti-DDoS Workflow of the FW: This section illustrates the anti-DDoS workflow of the FW.

Mechanisms of SYN Flood Attack and Defense: This section describes the mechanisms of SYN flood attack and defense.

Mechanisms of UDP Flood Attack and Defense: This section describes the mechanisms of UDP flood attack and defense.

Mechanisms of ICMP Flood Attack and Defense: This section describes the mechanisms of ICMP flood attack and defense.

Mechanisms of DNS Request Flood Attack and Defense: This section describes the mechanisms of DNS request flood attack and defense.

Mechanisms of DNS Reply Flood Attack and Defense: This section describes the mechanisms of DNS reply flood attack and defense.

Mechanisms of HTTP Flood Attack and Defense: This section describes the mechanisms of HTTP flood attack and defense.

Mechanisms of HTTPS Flood Attack and Defense: This section describes the mechanisms of HTTPS flood attack and defense.

Mechanisms of SIP Flood Attack and Defense: This section describes the mechanisms of SIP flood attack and defense.

Mechanisms of ARP Flood Attack and Defense: This section describes ARP flood attack and defense mechanisms.

Defense Threshold: This section describes the defense threshold. An appropriate defense threshold brings about effective anti-DDoS.

Single-Packet Attack Defense: This section describes the mechanism of single-packet attacks and how the FW defends against the attacks.
