Cybersecurity Recommendations Appendix 1

Cybersecurity is more than just a buzzword: it’s something that pertains to every device that is
connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic
steps toward protecting and strengthening networks and networked appliances will make them
less susceptible to attacks. Below are some tips and recommendations on how to create a
more secured security system.

Mandatory actions to be taken for basic equipment 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

equipment (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 equipment 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 equipment network security:

1. Physical Protection

We suggest that you perform physical protection to equipment, especially storage devices.
For example, place the equipment 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 equipment (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 equipment 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.

Cybersecurity Recommendations 22

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. Enable Whitelist

We suggest you to enable whitelist function to prevent everyone, except those with
specified IP addresses, from accessing the system. Therefore, please be sure to add your
computer’s IP address and the accompanying equipment’s IP address to the whitelist.

8. 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.

9. Assign Accounts and Privileges Reasonably

According to business and management requirements, reasonably add users and assign a
minimum set of permissions to them.

10. 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.

11. 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.

12. 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.

13. 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.

14. 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.

Cybersecurity Recommendations 23

 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.
