Abstract
A method system for analyzing interaction security a TCP/IP layered network model includes: acquiring a cross-layer interaction vulnerability set in the TCP/IP layered network model, and converting target protocol stack source codes into intermediate representations (IRs); dividing a network protocol stack into different layers by scanning the converted IRs, and obtaining source key variables by marking variables for indicating cross-layer interaction in the network protocol stack; obtaining propagation variables by marking variables based on a relationship with the source key variables, and obtaining a propagation path based on a marking sequence of the propagation variables; and obtaining a vulnerability detection result, by performing vulnerability detection based on the propagation path and the cross-layer interaction vulnerability set.
