Cybersecurity Recommendations

Use a strong password. At least 8 characters or a combination of characters, numbers, and
upper and lower case letters should be used in your password.

Set the password expiration time and regularly change the passwords of your devices to
ensure that only authorized users can access the system (recommended time is 90 days).

The system will automatically check the latest firmware version once a day. Once the
latest version is checked, you’d better update it to ensure the system is current with the latest
security patches and fixes.

It is recommended to change the service default ports (like HTTP-80, HTTPS-443, etc.) to
reduce the risk of outsiders being able to access.

It is recommended to set the firewall of your router. But note that some important ports
cannot be closed (like HTTP port, HTTPS port, Data Port).

It is not recommended to expose the device to the public network. When it is necessary to
be exposed to the public network, please set the external hardware firewall and the
corresponding firewall policy.

It is not recommended to use the v1 and v2 functions of SNMP.

In order to enhance the security of WEB client access, please create a TLS certificate to
enable HTTPS.

Use black and white list to filter the IP address. This will prevent everyone, except those
specified IP addresses from accessing the system.

If you add multiple users, please limit functions of guest accounts.

If you enable UPnP, it will automatically try to forward ports in your router or modem. It
is really very convenient for users, but this will increase the risk of data leakage when the
system automatically forwards ports. Disabling UPnP is recommended when the function is not
used in real applications.

Check the log. If you want to know whether your device has been accessed by
unauthorized users or not, you can check the log. The system log will show you which IP
addresses were used to log in your system and what was accessed.
