【 SYN Flood Threshold Blocking Time ( Per Source IP) Seconds】: The
System Administrator can enter the blocking time when the number of SYN
packets per second from attacking source IP Address that is allow to enter
the network/Bandwidth Manager exceed the maximum number (define as
above). After blocking for certain seconds, the device will start to calculate
the max number of SYN packets per second from attacking source IP
Address, if the max number still exceed the define value, it will block the
attacking IP Address continuously.
! Detect ICMP Attack: Select this option to detect ICMP flood attacks. When
hackers continuously send PING packets to all the machines of the LAN
networks or to the Bandwidth Manager via broadcasting, your network is
experiencing an ICMP flood attack.
【 ICMP Flood Threshold( Total) Pkts/Sec】: The System Administrator can
enter the maximum number of ICMP packets per second that is allow to
enter the network/Bandwidth Manager.
【 ICMP Flood Threshold( Per Source IP) Pkts/Sec】: The System Administrator
can enter the maximum number of ICMP packets per second from attacking
source IP Address that is allow to enter the network / Bandwidth Manager.
【 ICMP Flood Threshold Blocking Time ( Per Source IP) Seconds】: The
System Administrator can enter the blocking time when the number of ICMP
packets per second from attacking source IP Address that is allow to enter
the network / Bandwidth Manager exceed the maximum number (define as
above). After blocking for certain seconds, the device will start to calculate
the max number of ICMP packets per second from attacking source IP
Address, if the max number still exceed the define value, it will block the
attacking IP Address continuously.
! Detect UDP Attack: The same as ICMP Flood.
【 UDP Flood Threshold( Total) Pkts/Sec】: The System Administrator can enter
the maximum number of UDP packets per second that is allow to enter the
network/Bandwidth Manager.
