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 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
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.
User’s Manual
10
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 the risk of ARP spoofing.
8. Assign Accounts and Privileges Reasonably
According to business and management requirements, reasonably add users and assign
a minimum set of permissions to them.
9. 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.
10. 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.
11. Secure Auditing
Check online users: we suggest that you check online users regularly to see if the
device is logged in without authorization.
Check device log: By viewing the logs, you can know the IP addresses that were used
to log in to your devices and their key operations.
12. Network Log
Due to the limited storage capacity of the device, 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.
13. Construct a Safe Network Environment
In order to better ensure the safety of device 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.
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
User’s Manual
11
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.
Enable IP/MAC address filtering function to limit the range of hosts allowed to
access the device.
