This command allows you to set the maximum number of SYN packets
allowed before a flood is detected. If the number of SYN packets are counted
within the time duration set by the command
security set IDS
floodperiod
is greater than the maximum value set here, the suspected
attacker is blocked for the time limit specified in the command
security set
IDS DOSattackblock
.
For example, using the default settings, if more than 20 SYN packets are
received per second for a 10 second duration, the attacker is blocked.
