Rujukan untuk melindungi Mikrotik dari Scanners bisa juga dilihat di link berikut: http://wiki.mikrotik.com/wiki/Drop_port_scanners , atau juga bisa copy paste dari bari perintah berikut ini:

ip firewall filter add chain=input protocol=tcp psd=21,3s,3,1 action=add-src-to-address-list address-list=”port scanners” address-list-timeout=2w comment="Port scanners to list" disabled=no
ip firewall filter add chain=input protocol=tcp tcp-flags=fin,!syn,!rst,!psh,!ack,!urg action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="NMAP FIN Stealth scan"
ip firewall filter add chain=input protocol=tcp tcp-flags=fin,syn action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="SYN/FIN scan"
ip firewall filter add chain=input protocol=tcp tcp-flags=syn,rst action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="SYN/RST scan"
ip firewall filter add chain=input protocol=tcp tcp-flags=fin,psh,urg,!syn,!rst,!ack action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="FIN/PSH/URG scan"
ip firewall filter add chain=input protocol=tcp tcp-flags=fin,syn,rst,psh,ack,urg action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="ALL/ALL scan"
ip firewall filter add chain=input protocol=tcp tcp-flags=!fin,!syn,!rst,!psh,!ack,!urg action=add-src-to-address-list address-list="port scanners" address-list-timeout=2w comment="NMAP NULL scan"
ip firewall filter add chain=input src-address-list="port scanners" action=drop comment="dropping port scanners" disabled=no

Baris perintah diatas di copy paste pada terminal mikrotik atau juga bisa dengan meremotenya fia ssh yang bisa kita gunakan dengan putty atau tool sejenisnya untuk melakukan remote pada server.
