The invention discloses a service-based killer chain analysis construction method, which belongs to the technical field of cooperative combat, and comprises the following steps: constructing a
service resource pool, and setting a
service discovery mechanism; on the basis of the fusion situation set, a situation switching event is recognized so as to perform local updating, and a three-level situation view is constructed; constructing a directed hyperedge, generating a directed
hypergraph in combination with function category constraints, generating a
dimensionality reduction state space based on multi-dimensional constraints, and generating an initial combat candidate set; configuring a management node, sending task invitation information to the initial combat candidate set in combination with the subtasks, generating a response scheme, performing adaptive screening, generating an initial killing chain, and performing failure
verification; constructing a servitization twinborn body, deducing the initial killing chain, and executing
delay at a calculation end so as to perform
elimination recombination or
delay optimization; a service combination template is constructed, an efficiency feedback mechanism is established, the superposition influence of frequent situation switching and
state space catastrophe is cooperatively solved, and the real-time performance of generation of the killing chain is remarkably improved.
