DYNAMIC DEFENSE
Dynamic defense can blacklist hosts dynamically when the UCM6510 is set to "Route" under web
GUI->Settings->Network Settings->Basic Settings: Method. If enabled, the traffic via TCP connection
coming into the UCM6510 can be monitored, which helps prevent massive connection attempts or brute
force attacks to the device. The blacklist can be created and updated by the UCM6510 firewall, which will
then be displayed in the web page. Please refer to the following table for dynamic defense options on the
UCM6510.
Table 12: UCM6510 Firewall Dynamic Defense
Enable dynamic defense. The default setting is disabled.
Configure the dynamic defense periodic time interval (in minutes). If the number
of TCP connections from a host exceeds the “Connection Threshold” within this
period, this host will be added into Blacklist. The valid value is between 1 and 59
when dynamic defense is turned on. The default setting is 59.
Blacklist Update
Interval
Configure the blacklist update time interval (in seconds). The default setting is
120. This defines how long the IP will be blocked once added into the UCM6510
