IPBan is a simple option for securing your machine while on the internet by blocking hackers and botnets via your firewall.
IPBan is designed to monitor failed logins and other bad behavior and then bans the offending IP addresses on Windows (and Linux). It is a highly configurable, lean, and powerful security solution to help keep you safe from malicious intrusion while online.
IPBan is capable of protecting RDP, SSH, and SMTP, as well as providing database protection for MySQL or SQL Server. Additional protections for systems that write to the event viewer or log files utilizing XML/regular expressions can be easily be added by reconfiguring IPBan's file.
