MikroTik merupakan salah satu router yang cukup handal untuk menangani kebutuhan di jaringan Anda. Dengan beberapa fitur diantaranya management bandwidth, ip firewall, web proxy, loadbalancing server membuat MikroTik banyak digunakan sebagai router di Warnet, Kantor, RTRW Net, sekolah, dan di perumahan.
Di bawah ini saya akan sedikit berbagi script untuk mengamankan MikroTik dari port scanner, DDOS dan netcut. Anda tinggal copy pastekan script di bawah ini pada Terminal Winbox Anda, dan MikroTik Anda akan bertambah tebal dinding keamanannya. No system was secure, so pelajari terus security di MikroTik Anda!!
