【Linux/Nmap】识别操作系统指纹

网络侦察的第一步是确定网络中哪些机器是处于激活状态的。Nmap就是这样一款检测操作系统是流行工具,不仅可以检测远程操作系统是否运行,同时也可以执行各种端口扫描。

nmap通过向目标主机发送多个UDP与TCP数据包并分析其响应来进行操作系统指纹识别工作。在使用Nmap扫描系统的同时,该工具会根据响应包分析端口的打开和关闭状态。下图选项告诉Nmap在发现主机后不执行端口扫描,只打印出响应扫描器的主机,一般被称为“ping扫描”。这种扫描不会引起目标网络太多注意。对攻击者来说,了解有多少主机处于激活状态比列出每个IP的端口和主机名要有价值得多。 ...
