Operation Manual
219
5.
Change Default HTTP and Other Service Ports
We suggest you to change default HTTP and other service ports into any set of numbers between
1024–65535, reducing the risk of outsiders being able to guess which ports you are using.
6.
Enable HTTPS
We suggest you to enable HTTPS, so that you visit Web service through a secure communication
channel.
7.
MAC Address Binding
We recommend you to bind the IP and MAC address of the gateway to the equipment, thus
reducing the risk of ARP spoofing.
8.
Assign Accounts and Privileges Reasonably
According to business and management requirements, reasonably add users and assign a
minimum set of permissions to them.
9.
Disable Unnecessary Services and Choose Secure Modes
If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to
reduce risks.
If necessary, it is highly recommended that you use safe modes, including but not limited to the
following services:
●
SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication
passwords.
●
SMTP: Choose TLS to access mailbox server.
●
FTP: Choose SFTP, and set up strong passwords.
●
AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords.
10.
Audio and Video Encrypted Transmission
If your audio and video data contents are very important or sensitive, we recommend that you
use encrypted transmission function, to reduce the risk of audio and video data being stolen
during transmission.
Reminder: encrypted transmission will cause some loss in transmission efficiency.
11.
Secure Auditing
●
Check online users: we suggest that you check online users regularly to see if the device is
logged in without authorization.
●
Check equipment 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 equipment, 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 equipment 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.
