Attack checks allow you to manage WAN security threats, such as continual ping requests and discovery via ARP scans. You can enable TCP and UDP flood attack checks to manage extreme usage of WAN resources. Additionally, you can block certain Denial-of-Service (DoS) attacks. These attacks, if uninhibited, can use up processing power and bandwidth and can prevent normal regular network services. You can also configure ICMP packet flooding, SYN traffic flooding, and Echo storm thresholds to suspect traffic from the offending source temporarily.

Attack Check
Attacks can be malicious security breaches or unintentional network issues that render the router unusable. Attack checks allow you to manage
WAN security threats, such as continual ping requests and discovery via ARP scans. You can enable TCP and UDP flood attack checks to
manage extreme usage of WAN resources.
Additionally, you can block certain Denial-of-Service (DoS) attacks. These attacks, if uninhibited, can use up processing power and bandwidth
and can prevent normal regular network services. You can also configure ICMP packet flooding, SYN traffic flooding, and Echo storm thresholds
to suspect traffic from the offending source temporarily.
