网络扫描隐蔽性分析

On the Concealment of Network Scanning

各种不同的网络扫描方法,其隐蔽性和效率根据不同的原理而各不相同。同种扫描也可以采用不同的使用策略和方法而改变其隐蔽性。分析了各种网络扫描的隐蔽性,提出了对付隐蔽扫描可以采取的一些通用策略,并针对不同的扫描方式给出相应的对策。

Different network scanning methods have different concealment and efficiency. Even the same can has different concealment under different conditions. In this paper we analyze the concealment of different kinds of network scan, and then put forward some general policies to deal with it. At last, we introduce the specific methods to different scan type.
