Overview:
When an attacker attempts to penetrate a targeted Linux/UNIX system, the first task involved is usually to discover which OS the system is running and then compromise it with known exploits. If you can thwart an attacker from identifying the OS, then you can make it much harder and more time-consuming for the attacker to compromise the system. One of the most popular tools for revealing the OS is Nmap. This sample hack from O'Reilly's Network Security Hacks shows how to effectively block Nmap from "fingerprinting" a Linux/UNIX system.
