Secure Auditing
●
Check online users: we suggest that you check online users regularly to see if the device is
logged in without authorization.
●
Check device log: By viewing the logs, you can know the IP addresses that were used to log in
to your devices and their key operations.
12.
Network Log
Due to the limited storage capacity of the device, the stored log is limited. If you need to save the
log for a long time, it is recommended that you enable the network log function to ensure that the
critical logs are synchronized to the network log server for tracing.
13.
Construct a Safe Network Environment
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.
