Network Security Simulation system

A network security simulation system. The network security simulation system is capable of analyzing a hacking procedure through a simulation on a network. The network security simulation system is based on a component model base which librarizes each component of a network system as an object. The network system which is an analysis target can be freely designed based on the library. At least one attacker node and at least one target node are set in the designed network system. Hacking commands are transmitted from the attacker node to a target node through various components of the network system to change a state of the target node. The changed target node state is analyzed by a result analysis unit and then provided to a user.
