open Ports - Securing QNAP

Post by j2019d » Wed Aug 28, 2019 8:39 pm

Hi :)

even tough i choosed "only use https", the ports 80, 8081, 8080 are open. port 631 (rpinter service?) too. did not found a way to close it.

Every unused port is a (possible) security lack...

thanks for any hint! :wink:

shouldn't be an issue if your nas is in your private lan only and not forwarded to wan

correct, but the qnap is running in a medium risk environment & open/free wlan, so i try to close everything not necessary.

an open wifi should be fenced off in a vlan or segregated subnet (some routers even have guest wifi with lan block)

otherwise https is as vulnerable as http

it's only securing the connection from eavesdropping ..nothing else
