The performance of the Least Squares Support Vector Machine model in network intrusion detection is directly affected by the penalization parameters,so a network intrusion de-tection model based on LSSVM model is improved by sparrow search algorithm for higher accura-cy.Compared with PSO-LSSVM model,GA-LSSVM model,GWO-LSSVM model and LSSVM model,the SSA-LSSVM model has the highest accuracy of network intrusion detection.SSA-LSSVM can achieve high-precision network intrusion detection,and provide decision-making ba-sis for network security maintenance and enhance intrusion detection function.
