Hi, Now I research how to scan quickly and effectively, and I try lowering number of ports. (I mean that I want more effective result with fewer ports). According to the book "Nmap Network Scanning" by Fyodor, at p.141, - 576 ports : 90% Effectivenss - 1558 ports : 95% Effectiveness I take "Effectiveness" as Coverage, so when I scan 600 ports, I guess coverage is over 90%. I want to estimate such number. However, I think I need 2 benchmarks: One is remote scanning(over the internet) case, and the other is internal scanning(such as inside my office) case. So I have 2 questions: 1) Are above number(Book "Nmap Network Scanning") estimated by remote scanning? or internal scanning? or mixed? 2) Does anyone know such a document about "Scan coverage and number of ports"?
