分布式端口扫描器Dnmap的设计与实现

Design and Implementation of Distributed Port Scanner Dnmap

nmap事实上成为现代各种扫描器技术上的标杆,但随着近年网络环境发生重大变化,它很容易被发现和拦截。需要对其进行分布式升级,以提高其隐蔽性和运行效率。分布式的dnmap保留了单机的nmap原有各种特点,同时把单个任务分布式化,基于多个设备或多个独立IP实施,在分布式的设备和独立IP地址足够多的前提下,可以减少扫描时间,并且不容易被发现和拦截。dnamp采用Master、Slave双角色的模式,进行分布式部署,将其应用于正面的网络攻防演练,有利于打造更安全稳定的网络环境。

In fact,nmap is the benchmark of modern scanner technology,but with the great changes in the network environment in recent years,it is easy to be detected and intercepted.It needs to be upgraded in a distributed way to improve its concealment and operational efficiency.Distributed dnmap retains the original features of single-machine nmap,and at the same time,it distributes a single task based on multiple devices or multiple independent IP addresses,which can reduce scanning time and is more difficult to be detected and intercepted on the premise that there are enough distributed devices and independent IP addresses.Dnamp adopts the dual-role mode of Master and Slave,and is deployed in a distributed way.Applying it to positive network attack and defense drills is conducive to creating a safer and more stable network environment.
