I am playing with NMAP in my small private network performing port scanning.
So far I went through scanning the following OSs (Unaltered new installations - Meaning no extra software installed!):
- Ubuntu 14.04
- Windows 2012
- Windows 2008 R2
- Windows 7
Expect for W7, all other OSs returned ports opened. Is W7 this safe in its original version or am I missing any parameter in my NMAP command?
