EFT can automatically disconnect and even ban the IP addresses of users who send an excessive number of invalid commands.
To automatically disconnect users after a defined number of invalid commands
In the administration interface, connect to EFT and click the Server tab.
On the Server tab, click the Site you want to configure.
In the right pane, click the Connections tab.
In the Network Usage and Security Settings area, next to Denial of Service settings, click Configure. The Anti-Flood/Hammer Settings dialog box appears.
Select the Disconnect user after <n> consecutive invalid commands check box, then type the number of invalid commands allowed before you disconnect the user. You can automatically add the user's IP address to the Site's banned IP address list by selecting the Add IP address to ban list if excessive invalid commands received check box. You can later remove the ban on the user by deleting the user's IP address from the list in the Site's IP Access/Ban List dialog box.
Click OK to close the dialog box.
Click Apply to save the changes on EFT.
