Abstract

A computer network defense scheme simulation execution system comprises the steps of (1) designing and achieving a formalized computer network defense scheme description language (CNDSDL) with context-free grammar, providing an extended backus naur form (EBNF), designing a language interpreter based on the CNDSDL; (2) proposing a scheme arrangement method based on the CNDSDL, wherein the method comprises a deadlock detection and scheduling algorithm for tasks in a defense scheme, guaranteeing correctness of the defense scheme; and (3) achieving simulation of the defense scheme in a GT net simulation platform, wherein the simulation comprises simulation of an identification section (IDS), a firewall, backups, recovering and linkage tasks among the IDS, a bug library and the firewall.

Description

technical field [0001] The invention designs and implements a computer network defense scheme simulation execution system, belongs to the technical field of computer network security, and relates to the description of the computer network defense scheme, the deployment of the scheme, and the simulation realization of the scheme. Background technique [0002] Due to the diversity and openness of the Internet itself, many software and hardware vulnerabilities in computer systems and network equipment, as well as the growth of the network scale and the increasingly complex structure, the relationship between various parts of the system is complex and diverse, and the means of network attacks are also complicated. With the development of diversity, people are faced with many risks brought by network security issues, which poses greater challenges to computer network defense. In order to meet the needs of ensuring the security of large-scale computer networks and application syst...
