Abstract:

This paper puts forward a hierarchical model of attack cognition first, and describes the cognition method of attack behavior by adopting the LAMBDA l ogic expression method based on time and space factors, and then puts forward a formal description method for the cognition of the attack process. Final ly the paper gives the application steps of the hierarchical cognition model in security situation awareness systems.
