Dynamic Defense
Dynamic defense is supported on the UCM6200 series. It can blacklist hosts dynamically when the LAN mode
is set to "Route" under Web GUISystem SettingsNetwork SettingsBasic Settings page. If enabled, the
traffic coming into the UCM6200 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 UCM6200 firewall, which will then
be displayed in the web page. Please refer to the following table for dynamic defense options on the UCM6200.
