The system tracks the logs on your server to identify unsuccessful login attempts. When a specific threshold of failed attempts from one IP address is reached, that address gets blocked for a predetermined duration. Numerous Windows Server machines face relentless attacks, as network scanners and RDP brute-force tools operate continuously. Over time, these tools could potentially discover a valid password, compromising your server's security. Additionally, RDP brute-force attacks can strain server resources, including CPU, RAM, Disk Space, and Network Bandwidth. Check your server's Security EventLog; how many failed login attempts are recorded there? You might find thousands of unsuccessful login attempts originating from a single IP address, indicating an ongoing effort to breach your server's defenses. It's crucial to monitor these logs regularly to enhance your security posture.
