Multi-level collaborative security policy deployment method, system, equipment and medium

The invention provides a multi-level collaborative security policy deployment method, system and device and a medium, and the method comprises the steps: deploying security policies layer by layer from an upper layer to a lower layer according to the hierarchical relation of all layers in a cross-layer security service; after the security strategies corresponding to the layers are executed on the layers, monitoring items of execution conditions of the layers are obtained, the monitoring items of the layers are fed back layer by layer from the lower layer to the upper layer, and calculation is carried out according to the feedback of the layers to obtain monitoring data; generating a Merkel monitoring tree according to the monitoring data and the issuing sequence of the security policies, and performing collaborative security policy management and control on each layer by verifying the Merkel monitoring tree; the invention provides a method for deploying security policies layer by layer from the upper layer to
