If you are running FTP on your Windows Server you may observe thousands of failed login attempts in your FTP logs.
These failed login attempts are brute-force attacks on your FTP server. Hackers are trying to guess your password
using special brute-force tools with dictionaries by rotating through hundreds and thousands of password variations.
Failed FTP Logon Attempts in IIS logs
Someday they may succeed and your server might be compromised!
Even if you have super strong password, brute-force attacks abuse your server resources: CPU, RAM, Bandwidth and Disk Space.
RdpGuard
allows you to protect your FTP Server from brute-force attacks.
RdpGuard works with any FTP Server software and any custom ports.
It monitors one or multiple FTP ports on your server and detects failed login attempts.
If the number of failed login attempts from a single IP address reaches a set limit (three by default),
the attacker's IP address will be blocked.
