A list of exceptions can be defined to include addresses that are considered secure, regardless of the number of failed connection attempts. You can easily configure the maximum number of failed logon attempts that will trigger IP blocking and set the amount of time that an address will be kept on the blacklist (by default, 24 hours). Block IP addresses that repeatedly fail to connect Together with the Windows firewall, the RdpGuard security mechanism ensures intrusion prevention. It works as a Windows service, which means that the protection system is kept active even if there is no logged in client. This ensures that remote desktops are protected against brute-force attacks and that your server is more difficult to break in. What this application actually does is constantly monitor the event log in order to detect consecutive connection attempts and immediately block the source IP address. RdpGuard is specifically designed to handle such situations, acting as a security layer for your server. Your Windows Server will be protected even if nobody is logged in.Repeated failed login attempts from the same IP address to a server might be a sign that someone is trying to guess the password and access the server without consent.
How can you protect your server from brute-force password-guessing attacks on RDP? The answer is RdpGuard – powerful tool that allows you to protect your Remote Desktop from brute-force attacks. This means that someone is trying to find a password to access your server. How many failed login attempts do you see? The log may note thousands of failed login attempts from a single IP address. Take a look at your server’s Security EventLog. Eventually they may find a password to access your server! Moreover, RDP brute-force attacks abuse server resources (CPU, RAM, Disk Space and Network Bandwidth).
Network scanners and RDP brute-force tools work 24/7. Many Windows Server machines are under constant attack. If the number of failed logon attempts from a single IP address reaches a set limit, the attacker’s IP address will be blocked for a specified period of time. It monitors the logs on your server and detects failed logon attempts. RdpGuard is a host-based intrusion prevention system (HIPS) that protects your Windows Server from brute-force attacks on various protocols and services (RDP, FTP, IMAP, POP3, SMTP, MySQL, MS-SQL, IIS Web Login, ASP.NET Web Forms, MS Exchange, RD Web Access, VoIP/SIP, etc).
