In order to better ensure the safety of device and reduce potential cyber risks, we
recommend:
●
Disable the port mapping function of the router to avoid direct access to the intranet
devices from external network.
●
The network should be partitioned and isolated according to the actual network needs. If
there are no communication requirements between two sub networks, it is suggested to
use VLAN, network GAP and other technologies to partition the network, so as to achieve
the network isolation effect.
●
Establish the 802.1x access authentication system to reduce the risk of unauthorized
access to private networks.
●
Enable IP/MAC address filtering function to limit the range of hosts allowed to access the
device.
