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 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.
