  • Fail2ban

    Free Linux Website

Out of the box Fail2Ban comes with filters for various services (apache, courier, ssh, etc).

    Fail2Ban is able to reduce the rate of incorrect authentications attempts however it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.
