Abstract
The invention provides an industrial control white list updating method and device, electronic equipment and a storage medium, and relates to the technical field of network security, and the method comprises the steps: when a DHCP message is captured, analyzing the DHCP message, and obtaining an MAC address of a DHCP client and a first IP address allocated to the DHCP client by a DHCP server; according to the MAC address, the first IP address and a first mapping relation, whether the first IP address is a redistributed or newly distributed IP address is judged, and the first mapping relation is used for recording the corresponding relation between the MAC address and the IP address; and under the condition that the first IP address is the redistributed or newly distributed IP address, updating the IP address in the industrial control white list according to the first IP address. According to the invention, the industrial control white list can be linked and updated according to the change of the IP address, and the accuracy of service security management and control is improved.
