Cybersecurity Recommendations Appendix 2
Mandatory actions to be taken for basic device network security:
1. Use Strong Passwords
Please refer to the following suggestions to set passwords:

The length should not be less than 8 characters.

Include at least two types of characters; character types include upper and lower case
letters, numbers and symbols.

Do not contain the account name or the account name in reverse order.

Do not use continuous characters, such as 123, abc, etc.

Do not use overlapped characters, such as 111, aaa, etc.
2. Update Firmware and Client Software in Time

According to the standard procedure in Tech-industry, we recommend to keep your device
(such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped
with the latest security patches and fixes. When the device is connected to the public
network, it is recommended to enable the “auto-check for updates” function to obtain
timely information of firmware updates released by the manufacturer.

We suggest that you download and use the latest version of client software.
"Nice to have" recommendations to improve your device network security:
1. Physical Protection
We suggest that you perform physical protection to device, especially storage devices. For
example, place the device in a special computer room and cabinet, and implement well-done
access control permission and key management to prevent unauthorized personnel from
carrying out physical contacts such as damaging hardware, unauthorized connection of
removable device (such as USB flash disk, serial port), etc.
2. Change Passwords Regularly
We suggest that you change passwords regularly to reduce the risk of being guessed or cracked.
3. Set and Update Passwords Reset Information Timely
The device supports password reset function. Please set up related information for password
reset in time, including the end user’s mailbox and password protection questions. If the
information changes, please modify it in time. When setting password protection questions, it is
suggested not to use those that can be easily guessed.
4. Enable Account Lock
The account lock feature is enabled by default, and we recommend you to keep it on to
guarantee the account security. If an attacker attempts to log in with the wrong password
several times, the corresponding account and the source IP address will be locked.
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 device, thus reducing
