SSH блокиране на "хакери"

[111111]

ако сте се зблъскавали с "брутфорсери" искащи достъп до вашата машина през SSH

то следния код би ги затруднил доста

 

/ ip firewall filter
add chain=input protocol=tcp dst-port=22 src-address-list=ssh_blacklist action=drop comment="drop ssh brute forcers" disabled=no 
add chain=input protocol=tcp dst-port=22 connection-state=new src-address-list=ssh_stage3 action=add-src-to-address-list address-list=ssh_blacklist address-list-timeout=1w3d comment="" disabled=no 
add chain=input protocol=tcp dst-port=22 connection-state=new src-address-list=ssh_stage2 action=add-src-to-address-list address-list=ssh_stage3 address-list-timeout=1m comment="" disabled=no 
add chain=input protocol=tcp dst-port=22 connection-state=new src-address-list=ssh_stage1 action=add-src-to-address-list address-list=ssh_stage2 address-list-timeout=1m comment="" disabled=no 
add chain=input protocol=tcp dst-port=22 connection-state=new action=add-src-to-address-list address-list=ssh_stage1 address-list-timeout=1m comment="" disabled=no

в допълнение

/ ip firewall filter
add chain=input protocol=tcp dst-port=22 action=accept comment="SSH traffic monitor" disabled=no

 

сега ще сте по спокойни с релеиката

Да обновим малко Drop правилото

/ip firewall raw
add action=drop chain=prerouting dst-port=22 protocol=tcp src-address-list=ssh_blacklist
