摘要
从TCP/IP协议的基本原理出发,讨论了计算机网络扫描技术的理论基础,对当前网络扫描的主要技术-端口扫描和远程操作系统扫描的内在机制作了扼要的分类和阐述,并初步探讨了网络扫描中逃避检测的方法。在此基础上,就先进的网络扫描器的设计思路提出了自己的建议,并给出了一个网络脆弱性扫描器实现的概念模型。
According to basic principles of TCP/IP,the paper presents theoretic basis of computer network scanning techniques,and then gives the compendious classification and explanation of intrinsic characteristic as for current pri-marily both scanning techniques,i.e.port scanning and remote operating system scanning.In addition,several scanning ways to evade detection are simply discussed.Based on it,some design ideas of advanced network scanners are proposed and an implementation concept model of a scanner is presented as well.
