Hello All, I had problems with the security server, the server is frequently attacked using bruteforce attacks. Is there an application that can perform automatic blocking when there are failed login to the ports smtp, pop3 port, and others?
Why don't you try the Smoothwall firewall appliance and its Guardian Active Response (GAR)-mod, and set this up around your perimeter?
GAR is able to add temporary firewall rules to drop connection attempts/attacks under a configurable period of time and works in conjunction with Snort.
