Applied NAS : All

Applied QTS version: All

Answer:

1.In Control Panel > Network & File Service > Telnet/SSH, Modify SSH port number from 22 to an uncommon one eg. 8822 and apply the setting, then reboot the NAS.

2.Remove any unneeded port forward to avoid being scanned from the public network, this will reduce the risk of attack. (Optional)
