Cybersecurity Recommendations
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
