● Change Default HTTP and Other Service Ports. It is recommended 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. ● Enable HTTPS. It is recommended to enable HTTPS, so that you visit Web service through a secure communication channel. ● Enable Whitelist. It is recommended 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. ● MAC Address Reservation/ Binding. It is recommended to bind the IP and MAC address of the gateway to the equipment, thus reducing the risk of ARP spoofing. ● Assign Accounts and Privileges Responsibly. In accordance to business and management requirements, add users and assign a minimum set of permissions to them. ● 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 9 | www.icrealtime.com ● 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. ● 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. ● 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 ● 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. ○ 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.
