Appendix 5 Cybersecurity Recommendations
Cybersecurity is more than just a buzzword: it’s something that pertains to every device that
is connected to the internet. IP video security 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 from Dahua on
how to create a more secured security system.
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
