RDP Defender is a new powerful tool available for free since the 9.20 release of TSplus. It enables you to protect your public server from hackers, network scanners and brute force robots that try to guess your Administrator login and password. Using current logins and password dictionaries, they will automatically try to login to your server hundreds to thousands times every minute. With RDP Defender, you can monitor Windows failed login attempts and automatically blacklist the offending IP addresses after several failures.
You can find it on the bottom of the gateway tile of the Admin Tool:
When you click on it for the first time a shortcut icon is automatically generated on your desktop.
You can of course configure it to match your needs, for example by adding your own workstation IP address, so this tool never blocks you. Open RDP Defender, click on the „Tools“ menu, then click on „Options and Whitelist“. You can add as many IP addresses as you want in the whitelist. These addresses will never be blocked by RDP Defender:
You can also set the maximum failed logon attempts from a single IP address (by default, it is 10). And the time of reset for failed logon attempts counters (by default it is 2 hours).
You can start, stop, restart, enable or disable the service by clicking on the service tab.
Caution: RDP Defender is not supported on Windows 2003 and Windows XP.
