Appendix 1 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 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.
