Cross-domain killer chain construction method, device and equipment based on meta-path

The invention relates to a meta-path-based cross-domain killer chain construction method, apparatus and device. The method comprises the following steps: acquiring target node type information of a target node in a combat network, and generating a meta-path set of a killing chain according to the target node type information; and traversing the weapon platform according to the meta-path set and the target type information of the newly added target node to obtain a target killing chain set. The target killing chain set is composed of a plurality of cross-domain target killing chains. And calculating the action effect of each cross-domain target killing chain by adopting an effect evaluation function, and obtaining the cross-domain target killing chain according to the action effect. By adopting the method, the simulation effect of different weapon platforms can be improved, and the quick construction of the cross-domain killing chain is realized. 本发明涉及一种基于元路径的跨域杀伤链构建方法、装置及设备。所述方法包括：获取作战网络中目标节点的目标节点类型信息，根据目标节点类
