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.
