摘　　要：蠕虫病毒、拒绝服务攻击等安全问题对网络防御构成了很大挑战。在网络带宽急剧下降的情况下,网络应急防御所用端口扫描方法的效率成为一个引人关注的问题。将遗传算法用于端口的应急扫描,提出了三种端口应急扫描策略,设计了端口应急扫描算法。仿真结果表明,该方法能够有效解决传统穷举扫描法面临带宽不足时出现的效率问题。Security problems of worm virus and denial of services attack bring great challenges to the defense of complex networks. In the circumstances of sharp fall of bandwidth of complex networks ,the efficiency of port scanning method for networks emergency defense becomes a conspicuous issue. By applying genetic algorithm to port emergency scanning, in this paper three types of emergency port scanning policies are presented and an emergency port scanning algorithm is designed. Results of the simulation indicate that, compared with traditional exhaus- tive port scanning method, the method presented in this paper can solve efficiency problem in the conditions of bandwidth shortage.
